I remember the first time I saw the slogan "charge for 5 minutes and talk for 2 hours", I immediately thought of those children who were alive and kicking all day. They are almost tireless in playing. They will be noisy in scenic spots or playgrounds until all the electricity is consumed. Then, in their parents’ arms or in the back seat of the car, they are still drinking or talking one second and falling asleep the next.

　　Next, it may often take only an hour to rest, and they can "resurrect with blood" and continue to play wildly. The reason why the baby is so tired is also a great reason.

　　However, although we all know this feature of children, do you know the reasons behind it? Why is there so much energy in their small bodies?

　　Comparable to triathletes.

　　At present, the most famous research on the amazing potential of children in anti-fatigue is an experiment done by researchers at the University of clermont-ferrand: they recruited three groups of volunteers, each with 12 people, who were national male athletes engaged in triathlon, cycling or long-distance running; 12 boys with an average age of 10 and a half; And 12 ordinary adult men who rarely engage in strenuous exercise participated in the study.

　　These three groups of volunteers were asked by the researchers to do two sets of 7-second cycling sprints, and then pedal their bicycles as soon as possible for 30 seconds.

　　After exercise, the researchers compared the energy production of different groups of volunteers, including aerobic exercise and anaerobic exercise. Among them, anaerobic exercise does not consume oxygen, but will produce a lot of lactic acid, which will cause muscle fatigue.

　　After that, the researchers compared the recovery rate of heart rate, blood oxygen level and lactate clearance rate of different groups of volunteers after exercise. Finally, the researchers found that children are not easily exhausted by cycling, which is equivalent to the fatigue of professional athletes.

　　In fact, in all tests, children’s physiological function performance is better than that of untrained adults, and their physical strength recovery speed is faster than that of professional athletes.

　　Muscle structure has advantages.

　　Although the experimental results are surprising, this advantage of children’s undeveloped body is not accidental, it is the result of children’s special body structure.

　　Don’t treat children as miniature adults, they are all "Little Superman" — — As far as muscle composition is concerned, children’s muscles are composed of 70% red muscle fibers and 30% white muscle fibers, while in adults’ bodies, red and white muscles account for 50% respectively.

　　This particularity of muscle structure means two completely different energy production mechanisms. White muscle fibers are mainly supplied with energy through anaerobic, that is, creatine phosphate (a high-energy molecule) and sugar (glucose) are directly supplied with energy, which can make muscles release strong explosive force in a short time. In contrast, red muscle fibers are powered by aerobic respiration.

　　Red muscle contains a large number of "small factory" mitochondria, which can use more oxygen and make the production more efficient. Therefore, although it is inferior to white muscle in explosive power and strength, red muscle has stronger endurance.

　　If an adult still has a lot of red muscle fibers, it is mostly inherited or the result of high-intensity training. But children do not benefit from training, but are born to be comparable to endurance athletes.

　　Small body shape is more divided

　　Children’s infinite energy not only comes from their unique muscle structure, but also benefits from their small body shape, which makes them have an extremely fast oxygen supply speed before their height soars in adolescence, and can deliver oxygen to all motor muscles in a short time to provide energy in time.

　　"It’s like the difference between a mouse and an elephant. Mice are small in size and have high oxygen demand, mainly relying on aerobic energy supply system; Elephants that are huge and bulky rely on anaerobic energy supply systems. " Sebastian Ratel, the leader of the research project, said, "In small animals, it takes much shorter time to transport oxygen."

　　As for the recovery speed, the experiment shows that the recovery rate of heart rate in children’s group is 85%, that of athletes is 60%, and that of untrained adults is only 40%.

　　Researchers attribute this outstanding performance of children to a more effective acetylcholine inhibition mechanism — — This neurotransmitter can slow down the beating speed of the heart through the parasympathetic nervous system (controlling the autonomous operation of the body).

　　Children also have outstanding performance in removing metabolic waste from the body. You know, metabolic waste is the culprit that disturbs muscle contraction. The research team tested the content of lactic acid in the blood of the tester — — Lactic acid is a metabolite produced by muscle fatigue. The test results show that compared with endurance athletes, children’s lactic acid disappears faster, and ordinary adults are far behind in this respect.

　　"Lightning speed" is the wonder of researchers for children’s physical recovery ability. They analyzed that this may be because children are smaller and their muscles are closer to the oxygen-rich blood pumped by the heart, so they can use oxygen more effectively. Children’s extra energy comes from slow muscle fibers, which contract slowly, protecting children from being injured by excessive exercise.

　　No need to exercise deliberately.

　　Although the metabolic ability is not limited by body shape, children’s legs are not strong enough, coordination is insufficient, and the toughness repair ability of tendon system is weak, which leads to low body efficiency and limited mechanical movement ability. It is true that children’s quick recovery makes people feel never tired, but it is not the case when they exercise for a long time.

　　After children enter adolescence, their bodies gradually turn to rely on anaerobic system, which, like their adult parents, makes them tired easily and slows down their recovery. Therefore, before puberty comes, it is best to focus on cultivating their sports skills and action effectiveness through coordinated exercise and motor function exercise, so as to improve sports efficiency, rather than focusing on improving aerobic metabolism, because children’s aerobic metabolism efficiency is already very high.

　　Therefore, there is no need to deliberately do aerobic exercise in childhood. On the contrary, from adolescence, it is necessary to continuously improve the motor function and efficiency of the body. Since children’s bodies grow rapidly and have a brand-new body cognition after entering adolescence, it is necessary to focus on improving aerobic metabolism at this time to maintain the body’s rapid recovery ability, delay the onset of fatigue, and prevent diabetes, obesity, insulin resistance and cardiovascular diseases.

　　Mentality and sleep also help.

　　In addition to the characteristics of physiological function, children’s mentality is a model of "living in the present". They devote themselves wholeheartedly to the present activities, crying if they want to, smile happily, naive and carefree, while we adults bear all kinds of pressures and worries of life every day, and have a lot of depressed negative emotions, which is also a great consumption of physical vitality and energy.

　　Needless to say, children can generally get much more abundant sleep recovery time than adults. According to the statistics of national data, the average sleep time of children under 5 years old is 10 ~ 12 hours, which is beyond our adults’ reach. (brown squirrel)

　　On May 9th, the Ministry of Agriculture held a press conference to launch and implement the "Five Actions of Agricultural Green Development". Ye Zhenqin, spokesperson of the Ministry of Agriculture, Liao Xiyuan, director of the Science and Technology Education Department of the Ministry of Agriculture, Zeng Yande, director of the Planting Management Department, Ma Youxiang, director of the Animal Husbandry Department, and Li Shumin, deputy director of the Fisheries and Fishery Administration Bureau, introduced the relevant situation and answered questions from reporters.

　　Ye Zhenqin introduced that in recent years, China’s agricultural development has continuously reached a new level, with bumper harvests year after year, abundant supply of cotton, oil, sugar, fruit and vegetable tea, meat, eggs and milk, aquatic products, etc., but it has also paid a great price. Agricultural resources have been overdrawn for a long time, overexploited, agricultural non-point source pollution has increased, and the agricultural ecological environment has lit up a "red light". Excessive use of chemical fertilizers, pesticides and other inputs, low utilization rate of crop straw, agricultural film recovery rate, livestock manure treatment and resource utilization rate, and continuous decline of marine fishery resources have become prominent problems facing the current agricultural ecological resources and environment. General Secretary of the Supreme Leader emphasized that Lucid waters and lush mountains are invaluable assets should adhere to the basic national policy of saving resources and protecting the environment, and promote the formation of a green development mode and lifestyle. The Ministry of Agriculture implemented the spirit of the important speech of the Supreme Leader General Secretary and the central government’s decision-making arrangements. In 2015, it launched a tough battle to prevent and control agricultural non-point source pollution, and put forward the goal and task of "one control, two reductions and three basics", which achieved good results. This year, the Ministry of Agriculture further focused on the key points, and launched the "Five Actions of Agricultural Green Development", such as the action of recycling livestock manure, the action of replacing chemical fertilizer with organic fertilizer for fruit, vegetable and tea, the action of straw treatment in Northeast China, the action of agricultural film recycling and the action of protecting aquatic organisms with emphasis on the Yangtze River.

　　Ye Zhenqin said that these five major actions are aimed at the outstanding problems and shortcomings facing the current green development of agriculture. These issues are highly valued by the central leadership, concerned by the masses and concerned by the society. Whether it can be solved well is related to the sustainable development of agriculture and the vital interests of ordinary people, especially the broad masses of peasants. Solving these problems will hold the "bull’s nose" of agricultural green development and grasp the key task of agricultural sustainable development. The implementation of the five major actions is an important deployment and major measure to promote the structural reform of the agricultural supply side, which is conducive to changing the traditional production mode, reducing the excessive use of inputs such as fertilizers, optimizing the production environment, improving product quality, and ensuring the supply of high-quality green agricultural products from the source; It is conducive to promoting the comprehensive management and resource utilization of agricultural production waste, turning waste into treasure and turning decay into magic. In the final analysis, it is conducive to slowing down the trend of excessive utilization intensity of agricultural resources and increasing non-point source pollution, and promoting the formation of a green development mode of agriculture in China and embarking on a sustainable development path.

　　Ye Zhenqin briefly introduced the contents of the five major actions:

　　Action on resource utilization of livestock manure.At the 14th meeting of the Central Leading Group for Finance and Economics, General Secretary of the Supreme Leader emphasized that accelerating the treatment and recycling of livestock and poultry breeding wastes has a bearing on the production and living environment of more than 600 million rural residents, which is a long-term good thing for the benefit of the country and the people. The implementation of this action is to solve the problem of low level of treatment and utilization of livestock manure in China, and to launch a tough battle for pollution prevention and control of livestock and poultry breeding in an all-round way. This year, the central government plans to arrange special funds, adopt the method of substituting awards for subsidies, focus on large livestock counties and large-scale farms, promote the resource utilization of livestock manure in the whole county, coordinate existing projects, and focus on supporting the construction of livestock manure treatment and utilization facilities; Focus on large-scale farm households, build a national platform for direct reporting of livestock and poultry farm information, and realize accurate support, accurate management and accurate service; Establish a national scientific and technological innovation alliance for recycling livestock and poultry waste, summarize and refine effective models, and guide local and large-scale farms to scientifically control livestock manure. Through the implementation of this action, the comprehensive utilization rate of livestock manure in China will reach more than 75%, and the matching rate of manure treatment facilities and equipment in large-scale farms will reach more than 95%. By 2020, the problem of recycling manure in large-scale farms will be basically solved.

　　Action on replacing chemical fertilizer with organic fertilizer for fruit, vegetable and tea.At present, the amount of chemical fertilizer used in horticultural products such as fruits, vegetables and tea accounts for 40% of the amount of agricultural chemical fertilizer, which is the field with the greatest potential to promote chemical fertilizer reduction. The implementation of organic fertilizer substitution action is to solve the environmental problems caused by excessive use of chemical fertilizer, and strive to build the organization mode, service mechanism and policy framework of organic fertilizer substitution in 3-5 years. In the process of promotion, we should pay equal attention to reduction and efficiency, coordinate production and ecology, and highlight key varieties, namely apples, citrus, protected vegetables and brand tea; Highlighting the dominant producing areas means selecting 100 key counties in the dominant and core areas of fruit, vegetable and tea to carry out pilot demonstrations of replacing chemical fertilizers with organic fertilizers, exploring replicable and popularized technical models and operating mechanisms, and building a number of green product bases, characteristic product bases and well-known brand bases. Through the implementation of this action, we will strive to reduce the amount of chemical fertilizer in the dominant fruit, vegetable and tea producing areas by more than 20% and the amount of chemical fertilizer in the core producing areas and well-known brand production bases (parks) by more than 50% by 2020.

　　Action on straw treatment in Northeast China.Northeast China is a big granary in China. The total amount of straw, especially corn straw, is large, and the average household straw output is 3.2 times of the national average. In 2015, the comprehensive utilization rate of straw in Northeast China was only 66.6%, which was 13.5 percentage points lower than the national average. It can be said that the straw problem in Northeast China has been solved, and the comprehensive utilization level of straw in China has reached a big step. This year, it is planned to allocate 600 million yuan from the central government to carry out pilot projects to promote the comprehensive utilization of straw in 60 major corn-producing counties in Northeast China. Vigorously promote recycling technologies such as deep ploughing and mulching, and promote the development of circular agriculture with straw as the link; Accelerate the cultivation of socialized service organizations for straw collection, storage and transportation, establish a full coverage service network in major corn-producing counties, and improve the professional level of straw collection, storage and transportation; Innovate and mature a number of new technologies, new processes and new equipment in the fields of straw returning to the field, feed and fuel utilization, and improve the standardization level of comprehensive utilization of straw; At the same time, we will promote the introduction and implementation of preferential policies such as land use, electricity consumption and credit, and establish an industrialization development mechanism with government guidance, market players and multi-participation. Through the implementation of this action, we will strive to achieve more than 80% comprehensive utilization rate of straw in Northeast China by 2020, and increase the utilization capacity of straw by more than 27 million tons.

　　About the recycling action of agricultural film.The total amount of agricultural film used in China is more than 2.6 million tons every year, but the recovery rate is less than 2/3. This action is mainly to solve the problem of "white pollution" caused by the difficulty and high cost of plastic film recycling at present. This year, 100 demonstration counties will be built in Gansu, Xinjiang, Inner Mongolia and other regions, with cotton, corn and potatoes as the key crops, and the application of thickened plastic film, mechanized picking, specialized recycling and resource utilization as the main direction, which will be implemented in succession and promoted throughout the county. Strengthen source control and accelerate the revision of plastic film standards; At the same time, adjust the subsidy policy, change from "make-up use" to "make-up recycling", pilot the extension system of producer responsibility for plastic film recycling, and explore the mechanism of "whoever produces and recycles" so that the responsibility for plastic film recycling will be transferred from users to producers. Through the implementation of this action, we will strive to achieve more than 80% recycling rate of agricultural film by 2020 and effectively control the "white pollution" of farmland.

　　On the protection of aquatic life with emphasis on the Yangtze River.The General Secretary of the Supreme Leader stressed that the restoration of the ecological environment of the Yangtze River should be placed in an overwhelming position, and great protection should be done together, instead of large-scale development. This action is mainly to solve the problem of continuous decline and deterioration of fishery resources and environment and promote the sustainable development of fishery. In the protection of aquatic biological resources in the Yangtze River, we will vigorously promote the rescue action plan for Chinese sturgeon and Yangtze finless porpoise, and take the lead in achieving a comprehensive ban on fishing in the aquatic biological protection zone in the Yangtze River basin. In strengthening the management and protection of marine fishery resources, we will focus on promoting "double control of fishing boats", "total management" and "fishing in summer", continue to clean up and rectify the "homeless network" and the "three noes" ships involved in fishing, and guide and support fishermen to change jobs; At the same time, actively promote the construction of marine pastures, proliferation and conservation of fishery resources. Through the implementation of this action, we will strive to effectively curb the decline of aquatic biological resources, the deterioration of water ecological environment and the decline of aquatic biodiversity in the Yangtze River basin, restore the growth of aquatic biological resources, and realize the coordination between the total output of marine fishing and the total carrying capacity of fishery resources by 2020.

　　Ye Zhenqin pointed out that the implementation of the "Five Actions of Agricultural Green Development" is not only related to the green development of agriculture itself, but also to the protection and sustainable development of the entire ecological environment and resources, and it is also an important way to beautify the rural living environment and promote the construction of new countryside. In the next step, the Ministry of Agriculture will work with the provincial agricultural departments to implement the concept of green development, promote the structural reform of agricultural supply side, and embark on a road of agricultural modernization with high output efficiency, product safety, resource conservation and environmental friendliness.

　　CCTV reporter:In recent two years, for the purpose of protecting the local environment, some areas have designated "no-feeding areas" and closed down livestock and poultry farms. At the same time, the import of livestock products from abroad has continued to increase. How can the Ministry of Agriculture coordinate the coordinated development of animal husbandry production and environmental protection in such a situation?

　　Ma Youxiang:In recent years, livestock manure has been increasingly criticized. But we should not forget that animal husbandry has provided a strong guarantee for the supply of meat, eggs and milk for urban and rural residents, and made great contributions to increasing farmers’ income and ensuring employment. Livestock manure is a by-product of large-scale farming and a developing problem.

　　In the past, it was scattered farming, and a few pigs were raised in one household, and all the livestock manure was returned to the field. At present, the level of large-scale livestock and poultry farming in China has reached 56%. Compared with the traditional decentralized farming, the labor productivity, resource conversion rate, livestock and poultry productivity, quality and safety guarantee ability, anti-risk ability and comprehensive competitiveness have all been revolutionized. However, large-scale farms have not only produced scale benefits, but also produced considerable scale manure. Livestock manure is an important resource, and it is inseparable from organic fertilizer to improve soil fertility and develop organic agriculture, and it is also an important raw material for clean energy. For example, biogas power generation can use livestock manure as raw material, which is also in line with the requirements and development direction of green development.

　　The Ministry of Agriculture has always attached great importance to the coordinated development of animal husbandry production and environmental protection. During the Twelfth Five-Year Plan period, it was put forward that the development of animal husbandry should pay equal attention to ensuring supply, safety and production, and develop environmentally friendly animal husbandry. Specifically, we should make overall plans in three aspects. First, make overall plans in guiding ideology. Adhere to the importance of ensuring supply, ecology and safety. Solve the problem of manure pollution in the development of animal husbandry, realize the development of animal husbandry with higher quality by promoting the utilization of manure resources, and promote the upgrading of animal husbandry with green development. We can’t simply pursue the development of animal husbandry without paying attention to the pollution of farming, and we can’t ignore the historical development stage and basic conditions and shut down and ban the farms. Second, we should make overall plans for work deployment. Whether it is the "Thirteenth Five-Year Plan" or the annual work arrangement, whether it is the policy design or the investment arrangement, it is necessary to achieve a coordinated balance between ensuring supply and protecting the environment. It not only supports the transformation and upgrading of animal husbandry, but also considers the resource utilization of manure. There are both requirements for delineating "no-breeding areas" and measures for adjusting and optimizing breeding areas. It not only supports standardized and large-scale farming, but also carries out green development demonstration creation. We should not only consider "planting for raising" but also "raising for planting" to realize a new development relationship of combining planting and raising and farming-animal husbandry cycle. Third, we should coordinate the implementation of work responsibilities. It is necessary to implement the local government’s territorial management responsibility for the resource utilization of livestock and poultry manure, and to implement the responsibility system of the mayor of the vegetable basket, which is an integral part of two responsibility.

　　Regarding the adjustment of pig layout, the contradiction between aquaculture and water environment is more prominent in the southern water network area because the water environment is relatively sensitive and the carrying capacity is relatively limited. In 2015, the Ministry of Agriculture issued "Guiding Opinions on Promoting the Adjustment and Optimization of Pig Breeding Layout in Southern Water Network Areas" to guide the southern water network areas to scientifically determine the suitable breeding scale according to the land carrying capacity, and also formulated and issued the "National Pig Production Development Plan" to optimize the regional layout and actively guide the transfer of pig production to areas with large environmental capacity such as Northeast China. Now, the trend of pigs going northward is very obvious. A large number of pig breeding has been transferred to four provinces and regions in Northeast China. The development of Northeast China has a foundation, resources and space, and it is a key area to undertake the transfer of pig industry. In the next step, the Ministry of Agriculture will further increase its support based on the adjustment of the layout of pigs in the country, and strive to make Northeast China an important supply base of pork products in the country, and truly realize the combination of planting and breeding and the cycle of agriculture and animal husbandry.

　　Economic Daily reporter:China is a big country that uses chemical fertilizers, and the use of chemical fertilizers plays an important role in ensuring the output of agricultural products such as grain. Why do you propose to implement the action of replacing chemical fertilizer with organic fertilizer for fruit, vegetable and tea?

　　Zeng Yande:We propose that organic fertilizer should replace chemical fertilizer, which is the need of the situation and the necessity of development. In the past, in order to ensure supply, the amount of chemical fertilizer was indeed too much. This will not only increase the cost, but also bring some impacts on the ecological environment. I want to point out that the current reduction of chemical fertilizer, including the development of organic fertilizer instead of chemical fertilizer, is not to abandon chemical fertilizer, but to reduce the unreasonable use in the past and reduce the momentum of excessive use. It is an important measure to replace chemical fertilizer with organic fertilizer to promote the green development of agriculture now.

　　I think there are three points in the significance of this action: First, reduce costs and increase efficiency. China is a big producer of fruits, vegetables and tea, but its comprehensive benefit is far lower than that of developed countries in Europe and America. An important reason is that the amount of chemical fertilizer is too high. The average amount of chemical fertilizer per mu of fruit trees in China is 37.4 kilograms, which is more than twice that of Japan, six times that of the United States and seven times that of the European Union. The average amount of chemical fertilizer per mu of vegetables is 47.6 kilograms, which is 12.8 kilograms higher than that of Japan, nearly 30 kilograms higher than that of the United States and more than 30 kilograms higher than that of the European Union. Now only by using organic fertilizers can the amount of chemical fertilizer be reduced and the production cost be reduced. The second is to improve quality and efficiency. Nowadays, many consumers say that the taste of fruits and vegetables is not as good as in the past, which is also related to the excessive use of chemical fertilizers. The experiment shows that the appearance and internal quality of the fruit in the orchard with organic fertilizer are obviously improved, which is what we often say is good taste and high commodity value. After applying organic fertilizer, the anthocyanin content in pericarp will be increased by 20%-30%, and vitamin C will be increased by 10%-30%. The third is to improve the environment. At present, there is a phenomenon in agricultural production. On the one hand, excessive use of chemical fertilizers brings soil acidification and eutrophication of water bodies, and on the other hand, livestock manure accumulation can not be effectively used to cause pollution. By replacing chemical fertilizer with organic fertilizer, we can combine agriculture and animal husbandry more closely, make use of livestock manure and improve the quality of agricultural products, which is a good thing for many purposes.

　　China national radio reporter:On the one hand, the "five major actions of agricultural green development" have a wide coverage and a great span. On the other hand, each action may have different priorities and progress. How to ensure that these actions can be promoted simultaneously and achieve practical results?

　　Ye Zhenqin:The "Five Actions of Agricultural Green Development" does have a wide coverage, many links and many subjects, which need to be promoted as a whole. Minister Han Changfu of the Ministry of Agriculture demanded that the Ministry of Agriculture should take the five major actions as the overall, strategic and long-term tasks of agricultural development, and must achieve practical results. From the perspective of the Ministry of Agriculture, there are many things to be done and many things that can be done. We focus on four aspects:

　　First, do a good job in organizational leadership. The Ministry of Agriculture has set up a leading group for five major actions, with Minister Han Changfu as the leader. Each leading group has a set of leadership promotion mechanism, and each action is under the overall responsibility of the vice minister as the "captain of the action". The lead departments are responsible for formulating plans, studying the promotion mechanism and strengthening the division of responsibilities. Some of these five action plans have been issued, and some are being formulated. The Ministry of Agriculture will formulate good policies, do a good job in top-level design, sum up good models, and push all localities to implement their work.

　　Second, do a good job of demonstration. The five major actions are a new task, and many of them need to carry out pilot projects first, explore models and sum up experience, and form a number of typical and governance models that can be replicated and promoted. For example, 100 demonstration counties (cities) have been selected for the action of replacing chemical fertilizer with organic fertilizer for fruit, vegetable and tea, which are not only big counties for fruit, vegetable and tea production, but also big counties for livestock and poultry breeding. For example, agricultural film pollution control, this year, 100 demonstration counties were established in Gansu, Xinjiang and Inner Mongolia to comprehensively promote the use of thickened plastic films and basically establish a recycling system. The recovery rate of plastic films in the demonstration counties reached more than 80% in the current season, taking the lead in realizing the basic resource utilization of plastic films.

　　Third, establish a mechanism to promote implementation. The implementation of the five major actions depends on the efforts of the government, the market and the society to form a joint force. Generally speaking, there are three sentences: First, government support is indispensable. This year, the Ministry of Agriculture will integrate the existing funds, actively strive for incremental funds, promote the effectiveness of various tasks through subsidies and other means, and gradually establish a policy and project system based on green ecology. Second, the market mechanism is more important. In these five major actions, except the aquatic organism protection action, the other four actions must establish a market-oriented operation mechanism, and at the same time give full play to the role of financial funds, and encourage the participation of third-party entities such as production and operation entities and governance entities. For example, in promoting the action of replacing chemical fertilizer with organic fertilizer, the government has adopted the way of purchasing services, and at the same time encouraged social capital to enter, inciting all kinds of capital to participate in the production, popularization and application of organic fertilizer. Third, the assessment constraints should be strengthened. The five major actions cannot be carried out by the agricultural sector alone, let alone by the Ministry of Agriculture, but also by local governments. We will establish a mechanism to promote implementation, so that there are standards and assessments, and link policy projects, funding arrangements and assessments to fully mobilize the enthusiasm of local governments and large-scale business entities.

　　Fourth, innovative technology model. The implementation of the five major actions is highly technical. The Ministry of Agriculture should give full play to the systematic advantages of professional technology and team, actively organize and carry out collaborative research in Industry-University-Research, increase the research and development of supporting new technologies, new products and new equipment, integrate and assemble a number of replicable and scalable technology models, and expand the scope of promotion. For example, the livestock manure recycling action has summed up seven kinds of manure recycling treatment modes, and issued them to all localities for reference, guiding local governments to adapt to local conditions and policies.

　　"Five actions of agricultural green development" is an overall war and a systematic project. In the next step, we will strengthen overall planning and coordination, integrate resources, and form a working pattern of joint management and linkage from top to bottom. In particular, it is necessary to highlight key areas, national modern agricultural demonstration zones, grain production functional zones, important agricultural product production protection zones, characteristic agricultural product advantage zones, agricultural sustainable development experimental demonstration zones and modern agricultural industrial parks, and take the lead in promoting the five major actions as a whole, establishing the mechanism and model of agricultural green development, so that the five major actions can see results as soon as possible and benefit the society and the masses as soon as possible.

　　Xinhua News Agency reporter:Plastic film mulching is known as the "white revolution" in agriculture, but the problem of "white pollution" caused by plastic film residue in rural areas is becoming increasingly prominent. How to deal with the dilemma of "white revolution" and "white pollution"?

　　Liao Xiyuan:Agricultural film is the fourth largest agricultural means of production after seeds, pesticides and fertilizers. It has obvious functions of warming, preserving moisture and weeding, and has made great contributions to increasing agricultural production and farmers’ income. However, with the increasing amount and service life of plastic film, it has also caused "white pollution" in some areas, which has become a prominent problem facing the green development of agriculture. In recent years, local agricultural departments have actively promoted the recycling of plastic film. First, they have strengthened the capacity building of plastic film recycling and processing. Support the construction of a number of waste plastic film processing enterprises and recycling outlets. The second is to strengthen the recycling and management of plastic film and vigorously implement the "five ones" comprehensive management of plastic film. Third, strengthen the scientific and technological innovation of plastic film, and combine with Industry-University-Research to carry out experiments and demonstrations of degradable plastic film.

　　In the next step, we will focus on the action objectives and key tasks, and strive to promote the work in five aspects. First, promote the revision of plastic film standards. Increase the thickness and stretching length of plastic film, improve the recoverability of plastic film and strengthen the source control. Second, promote demonstration and lead, focus on 100 demonstration counties in the northwest, concentrate on investment, integrate technology, and create demonstration models. Third, promote mechanism innovation, adjust and implement relevant subsidy policies, change from "supplementary use" to "supplementary recycling", accelerate the study of the extension mechanism of producer responsibility for plastic film recycling, and explore the transfer of responsibility for plastic film recycling from users to producers. Fourth, promote scientific and technological innovation, organize scientific and technological forces, focus on tackling key problems of degradable plastic films, picking up residual films and researching and developing processing machinery, establish a monitoring and investigation system for agricultural films, strengthen statistical analysis and improve the assessment index system. Fifth, promote the implementation of the work, clarify the division of responsibilities, departments cooperate with each other, and the main body cooperates to form a joint force to ensure that the measures are fully implemented.

　　People’s Daily reporter:In the action of replacing chemical fertilizer with organic fertilizer for fruit and vegetable tea, it is mentioned that by 2020, the amount of chemical fertilizer in the dominant producing areas of fruit and vegetable tea in China will be reduced by more than 20%, and the amount of chemical fertilizer in the core producing areas and production bases of well-known brands will be reduced by more than 50%. Can this goal be achieved? What measures need to be taken if it is achieved on schedule?

　　Zeng Yande:The action of zero growth in fertilizer use has been implemented for three years and achieved initial results. Last year, the use of chemical fertilizers was almost zero, and the growth rate was slowing down. Some provinces had already experienced negative growth, and the atmosphere was forming. We propose that by 2020, the amount of chemical fertilizer will be reduced by more than 20% in the dominant areas where fruit, vegetable and tea organic fertilizer replaces chemical fertilizer, and by more than 50% in the core areas and well-known brand production bases. This goal is fully demonstrated and can be achieved through hard work.

　　We consider the following points, mainly the "five movements". First, policy support and promotion. Nowadays, the cost of rural labor is increasing, and it is time-consuming and laborious for farmers to apply organic fertilizer and farmyard manure, so it is necessary to support farmers to apply organic fertilizer through policy guidance. This year, the central government has arranged special funds to support the replacement of chemical fertilizers with organic fertilizers for fruits, vegetables and tea, and at the same time, combined with biogas projects, pilot projects for resource utilization of livestock manure and other projects, they have promoted in the same direction and formed a joint policy force. Beijing, Shanghai, Jiangsu, Zhejiang and other provinces and cities have arranged special funds to support farmers to use organic fertilizer, and accumulated a set of good practices, and the policy effect is very good. The second is the combination of agriculture and animal husbandry. Encourage the local use of livestock and poultry manure and other aquaculture waste, and build and apply organic fertilizer. The demonstration county of replacing chemical fertilizer with organic fertilizer for fruit, vegetable, tea is also a large breeding county, realizing recycling and turning waste into treasure. The third is driven by technological innovation. For example, the composting of livestock manure, the application of commercial organic fertilizer, and the harmless treatment of biogas residue and biogas slurry, a set of replicable and popularized technical models are preliminarily put forward. It is also necessary to innovate the service mechanism, incite social capital, and invest organic fertilizer instead of chemical fertilizer. Some places have already had good experience. The fourth is the demonstration of new business entities. New business entities have initiative and enthusiasm for the utilization of organic fertilizer, so they should play their exemplary role in standardization, scale and intensive utilization, and lead organic fertilizer to replace chemical fertilizer. The fifth is the promotion of brand base. By implementing organic fertilizer instead of chemical fertilizer, we will produce the best quality agricultural products with the healthiest soil, and build a number of green product bases, characteristic product bases and well-known brand bases.Increase the supply of green products. Some bases are doing very well, using organic fertilizer, creating organic food, and doing brand sales to meet consumers’ diversified and characteristic consumption needs. We believe that through the promotion of these measures, the goal of reducing fertilizer consumption can be achieved through three to five years’ efforts.

　　Farmer Daily reporter:May I ask how the Ministry of Agriculture will promote the new summer fishing moratorium system and achieve a total ban on fishing in the aquatic life reserve in the Yangtze River basin? In addition, what specific measures are there in the construction of marine pasture?

　　Li Shumin:This problem involves three aspects. First, regarding the system adjustment of summer fishing moratorium, in order to ensure the implementation of the new summer fishing moratorium, on May 1, the Ministry of Agriculture, together with the China Marine Police, carried out special enforcement actions on summer fishing moratorium in Xiangshan, Zhejiang, Dalian, Liaoning and Sanya, Hainan around key areas, key time periods and key targets. The key areas are fishing ports and fishing grounds, and the key periods are one end and one end during the summer fishing moratorium and the licensed fishing implementation period. The key targets are fishing auxiliary vessels, licensed fishing vessels, vessels with special operation methods, vessels with "criminal records" that have repeatedly violated the summer fishing moratorium in the past, and vessels with "three noes" involved in fishing. In order to ensure the effectiveness of law enforcement, we will focus on strengthening the linkage between law enforcement departments, land and sea, inside and outside the line, so as to achieve the stability of fishing order and social stability in fishing areas in summer.

　　With regard to taking the lead in realizing a total ban on fishing in the aquatic biological reserve in the Yangtze River basin, we adopt the method of retreating first and banning later. First, we will promote the fishermen in protected areas to retreat and land, and then issue a fishing ban on relevant waters, and steadily promote the comprehensive ban on fishing in protected areas. In the next step, we will, in accordance with the principle of "central guidance and local support", make overall plans to promote the implementation of policies for fishermen to settle down ashore, education, medical insurance, subsistence allowances, old-age care and poverty alleviation, strengthen practical skills training, and strive to broaden the channels for increasing income of fishermen who have retired ashore, and strive to ensure that fishermen are guaranteed to be retired and protected areas are prohibited from catching.

　　Based on the principle of marine ecosystem, marine pasture is a fishery model that constructs or repairs the places needed by marine organisms to breed, grow, seek prey or avoid natural enemies by artificial reefs, proliferation and release, etc. in specific sea areas, so as to proliferate and conserve fishery resources, improve the ecological environment of sea areas and realize sustainable utilization. Since 2002, the Ministry of Agriculture has actively supported the local development of marine pastures. Up to now, China has invested 5.58 billion yuan in the construction of marine pastures, which has produced obvious ecological, social and economic benefits. Through the combination of marine pasture with marine sightseeing and leisure fishing, the country has accepted more than 16 million tourists every year, which has become a new bright spot of marine economic growth. Since 2015, the Ministry of Agriculture has organized the establishment of national-level marine pasture demonstration zones, and it is planned to create a number of national-level marine pasture demonstration zones with strong regional representation and outstanding public welfare functions in about five years. Up to now, we have created two batches of 42 national marine pasture demonstration areas. This year, we will also organize a national on-site meeting on the construction of marine pastures, sum up advanced models, popularize advanced experience, and promote the development of marine pastures in China to a new level.

　　Xinhuanet reporter:As a big granary in China, the average straw yield in Northeast China is much higher than the national level, but its comprehensive utilization rate is lower than the national level. Excuse me, how to promote the comprehensive utilization of straw according to the characteristics of Northeast China?

　　Liao Xiyuan:On the one hand, the total amount of straw in Northeast China is large, returning to the field is slow and the cost of leaving the field is high. On the other hand, the organic matter content in black land needs to be improved urgently, and farmers have a strong demand for heating in winter. In carrying out straw treatment in Northeast China, we will focus on improving the agricultural level of straw, the specialization level of collection, storage and transportation, the standardization level of comprehensive utilization and the improvement of market utilization level, with fertilizer, feed and fuel utilization as the three main directions, and earnestly do seven enhancements. The first is to strengthen the implementation of responsibilities. Implement the responsibilities of local governments at all levels and production and operation entities, and form a working pattern of joint management and linkage from top to bottom. The second is to strengthen policy support. Further increase support for straw returning to fields, collection, storage and transportation, processing and utilization. The third is to strengthen resource integration. Increase the integration and utilization of project funds, concentrate on the use of funds with other agriculture-related projects, and integrate forces to achieve key breakthroughs. The fourth is to strengthen market leadership. Comprehensive utilization of taxation, finance and other policies to stimulate the vitality of market players, and accelerate the establishment of an industrial utilization mechanism for the stable operation of all aspects of straw storage, storage, transportation and marketing. The fifth is to strengthen regional focus. Focus on key areas, take counties as units, increase project support, and ensure that these places meet the standards first. The sixth is to strengthen performance appraisal. Adopt a third-party assessment mechanism to regularly supervise the implementation of the action plan and promote the implementation of the work. Seventh, strengthen publicity and training. Summarize the typical experience in time, strengthen the model promotion, carry out a series of training at different levels and subject, and make full use of the Internet and other media to publicize the successful experience and good practices of straw treatment in Northeast China.

　　Agricultural materials reporter:The straw treatment action in Northeast China proposes to carry out pilot projects in 60 major corn producing counties in Northeast China to promote the introduction of subsidy policies. Is the list of 60 major corn producing counties confirmed? What adjustments will be made to the subsidy policy compared with last year?

　　Liao Xiyuan:We propose to carry out demonstration work in 60 counties, but further communication is needed in the northeast, and selection should be made according to procedures. Promote the implementation of the subsidy policy for comprehensive utilization of straw, mainly including straw returning to the field, collection, storage and transportation, processing and utilization. For example, returning farmland needs to subsidize agricultural machinery and farming, and plowing needs to subsidize bundling machinery and specialized organizations. In terms of straw storage, it is necessary to promote the local authorities to introduce a system for the management of protected agricultural land for the temporary storage yard of straw storage, and give certain subsidies to the storage yard with a storage capacity of more than 10,000 tons. In terms of processing and utilization, it is necessary to promote the local power consumption for straw processing to be included in the scope of agricultural power; In the aspect of fuel utilization, it is necessary to support the development of biomass heating and gas supply enterprises, and give subsidies to straw briquette cooking heating stoves.

Special feature of 1905 film network After the film directed by Tian Zhuangzhuang, the fifth generation director of China, was released in 1986, the audience couldn’t understand it because it was too small and had a poor reputation. At that time, he left a "cruel remark": "My film was made for people in the next century".

Although Tian Zhuangzhuang clarified that this was a joke, more than 30 years later, horse thief really crossed the century and came to Cannes Film Festival for its premiere with a totally new look of 4K48 Tibetan dubbing.

On May 17th, Tian Zhuangzhuang came to the premiere under the guidance of Fu Mao, the artistic director of Cannes. He recalled that he was invited to Cannes during the filming of horse thief in 1985, and 34 years later, he revisited his hometown with horse thief, which was very predestined.

Cannes Classic Unit was founded in 2004. In the past 15 years, Chinese films selected for this unit have been selected. This time, the restored version of "horse thief" is the first time that an independent restored film from the mainland of China has been selected for this unit, and another domestic restored film has also been selected.

After the release of horse thief, we talked with director Tian Zhuangzhuang, photographer Hou Yong and relevant persons responsible for restoration and overseas distribution about this restored version of past lives. This film goes to the world in the form of restoration, which also opens a new way for other China classic films to open up international visibility and audience.

Horse thief has been restored three times.

Horse thief was once listed by martin scorsese as one of the top ten personal films in 1990s, and also highly praised by movie master Bertolucci and Evans.

The film tells the story of a poor Tibetan herder, Rolb, who steals horses for a living and struggles with his family between making a living and faith. It is a film that dilutes the story, breaks through the narrative tradition, and has both practical significance and religious color.

However, the film’s dirty spots, scratches, particle jitter and fading over time have greatly affected the viewing effect of the film. In 2017, the restoration team of China Film Archive began to repair the film.

After three times, for the first time, it was repaired with 2K technology. After reading it, Tian Zhuangzhuang found that there was a big problem, so he asked the photographer Hou Yong to supervise it. For the second time, it further adopted 4K and 48-frame restoration projection technology to improve the restoration effect.

Hou Yong introduced us that he first adjusted the frame, "If you don’t adjust it, it will really be finished. The frame is wrong, not 1: 2.35, but it seems to be cut into a feeling of 1: 1.6 or 1: 1.85." Secondly, he gave advice on color matching. He and Tian Zhuangzhuang insisted that the color of the picture should not be too bright. "Now the digital color is fake and calculated, because there is no film now, everyone has long since.

At the same time, there are some detailed adjustments. For example, a picture of a night play taken on a daily basis, the first repair version is still adjusted to the brightness of the day, and the second repair is close to the feeling of a night play. Hou Yong said frankly that his participation was to restore and get closer to the color sense of the film and the desired picture effect when shooting at that time.

Tian Zhuangzhuang didn’t personally participate in the restoration process. He said that his only advice was to find Tibetan audio tracks, because Tibetan is more authentic and natural than Chinese dubbing. Three months after the idea was put forward, China Film Archive found the Tibetan sound file from France and re-made it into 5.1 channels, which also contributed to the completion of the latest Tibetan restored version.

Judging from the screening effect in Cannes, the quality of the film is very clear, and there are also very pleasing colors. Tian Zhuangzhuang also praised us: "This is the best of all the restored versions of the fifth-generation film I have ever seen."

Zuo Heng, the representative of China Film Archive, also came with Tian Zhuangzhuang and his party this time. He deeply regrets the restoration process of horse thief:

"Restoration is a very delicate state. For example, we think that the film is a little dim and needs to be brightened, but this may not be what the director and photographer wanted at that time." It is precisely because of the guidance of the creative team such as Hou Yong that the restoration effect is closer to the original appearance.

As for the early domestic films, Zuo Heng revealed that he could only get information from the director’s notes, review articles, photos and other documents at that time to repair them. "Just like repairing the old mural, it may have been painted by Leonardo da Vinci, but later generations should repair it, whether it is right or wrong, even if there is a mistake, there should be an aesthetic embodiment."

How to restore the film to the world

Digital restoration technology has brought a new round of criticism of classic films, and re-examined the artistic value and historical value of films, and the international market of restored films has also become active in recent years.

Zuo Heng told us that the current overseas distributors are very interested in classic old films. Compared with the new films, it takes a lot of energy to make publicity. Most of the old films have passed the time certification, and they can log in to cinemas, online platforms or make DVDs in various countries through multi-channel and sub-regional distribution.

Xie Meng, head of Chek Lap Kok Culture, led the overseas distribution of the restored version of horse thief. He introduced the film to Cannes as their first stop. "Through the platform of Cannes Film Festival, it can be introduced to more filmmakers, curators of other national film archives or overseas distributors, and then they will take the film to their respective markets or film festivals."

Next, they will take the restored version of horse thief to the second stop of overseas promotion: Lyon Film Festival, because there is a distribution market dedicated to the restoration of classic films.

Xie Meng believes that there is a certain profit margin in overseas distribution of domestic classic restoration films, which can be released as a new film model with relatively simple operation.

He also said that whether it is cultural activities organized by the government, exchanges in film festivals, or promotion through international sales channels, the most important thing for China to restore classic films to the world is the film content itself. "What kind of content is released in what channel will determine the width and breadth of the final spread."

In addition to the restored version of horse thief and the restored version of Diary of a Nurse, which will premiere in Cannes, there will be many domestic classic restored films, such as (1965) and (1956) and 2-3 4K restored films planned by China Film Archive every year, and this international trip of horse thief will also enable them to go global in the future and gain more effective promotion experience.
