Economic benefit and health value of green agriculture

Green agriculture is "big agriculture" in a broad sense, which includes: green animal and plant agriculture, white agriculture, blue agriculture, black agriculture, fungus agriculture, facility agriculture, horticultural agriculture, sightseeing agriculture, environmental protection agriculture, information agriculture and so on. In specific applications, we generally refer to the "three products", namely pollution-free agricultural products, green food and organic food, as green agriculture. After China's entry into WTO, the international market requires high-grade, high-quality and excellent varieties of agricultural products and non-toxic, harmless and pollution-free agricultural products. China must take the road of green agriculture development. Suggestions on the development of green agriculture in China are as follows: First, the combination of multiple species and main species should be adopted in the model to form reasonable competition among species and make full use of various energy sources in unit space; Secondly, in terms of space allocation, the collocation form, density and space of species should be properly applied, so as to improve the utilization length of time; Thirdly, the production structure should be carried out according to the law of energy conversion and material circulation, and the efficiency of energy conversion and material circulation can be improved by prolonging or perfecting the food chain and improving the trophic level. If we can change the slack farming into busy farming from two crops a year, the integration of yard planting, breeding and processing will help solve the transfer problem of surplus idle rural labor; Fourthly, technically, we should make full use of the scientific combination of various technical measures to form an agricultural system that combines mechanical technology with food technology, organic agricultural technology with inorganic agricultural technology, and realize the organic unity of long-term ecological benefits and economic benefits: form an efficient agricultural group that is suitable for forest, grazing, water and tourism. The so-called economic benefit of green agriculture refers to the agricultural production and operation mode with the production, processing and sales of green food as the axis. Green food refers to pollution-free, safe, high-quality and nutritious food produced in a specific way according to the principle of sustainable development, which is recognized by specialized agencies and allowed to use green marks. At present, actively developing green agriculture has become a strategic measure to meet international challenges. The economic benefits are remarkable! At the same time, developing green agriculture is also the need to adhere to sustainable development and protect the environment. The operation mode of "black agriculture" is often highly dependent on large-scale agricultural machinery, fertilizers and pesticides, which not only consumes a lot of non-renewable energy, but also causes soil erosion, air and water pollution. Developing green agriculture can fundamentally solve these problems. Green agriculture takes "green environment", "green technology" and "green products" as the main body, which promotes the transformation from chemical agriculture that relies too much on chemical fertilizers and pesticides to ecological agriculture that mainly relies on biological internal mechanism. Northeast China is an important grain producing area in China. Summarizing the experience and lessons of developing agriculture in advanced areas at home and abroad, we can see that there are three main ways to develop agriculture in Northeast China today with global economic integration and domestic economic marketization: first, optimize industrial structure; Second, adjust the structure of national fiscal expenditure and increase support for agriculture; The third is to improve the competitiveness of agricultural products, including participating in international competition, such as developing green agriculture. The first two items must be solved by the government and the market, and only the third item is the most fundamental, that is, fundamentally changing the mode of agricultural operation. Northeast China has unique advantages for developing green agriculture, and can become a big economic zone for developing green agriculture in China. First, fertile soil and superior geographical environment are favorable conditions for developing green agriculture. There are Sanjiang Plain, Songnen Plain and Liaohe Plain in the northeast. Most of these great plains are black soil in Ma Pingchuan, with fertile soil, deep soil layer, good soil quality and flat cultivated land. In addition, Changbai Mountain and Daxinganling Mountain, which are unique in Northeast China, are natural barriers in Northeast Asia and have great economic and ecological values. This is the basic condition for developing green agriculture in Northeast China. Secondly, the achievement of eco-province construction is a solid subjective condition for developing green agriculture. The state approved Jilin and Heilongjiang provinces as ecological pilot provinces in China. These two provinces have made remarkable achievements in the construction of ecological provinces, laying a solid foundation for developing green agriculture and promoting the improvement of ecological environment. Third, industrial economic base and scientific and educational advantages are the material basis for developing green agriculture. Northeast China has the advantages of perfect industrial system, science and education, human resources, infrastructure and rich agricultural products resources. These are solid material foundations for developing green agriculture. Fourthly, the establishment of green food production base and the development of its products have opened up a new situation for the development of green agriculture. The three northeastern provinces have established a number of green food production bases and created a number of green food brands. This has played an exemplary role in developing green agriculture in Northeast China, thus opening up a new situation in developing green agriculture in Northeast China. Although there are many favorable conditions for developing green agriculture in Northeast China, to fundamentally change people's farming methods and agricultural products circulation methods for thousands of years, we need to carry out major reforms in concepts, farming techniques, material input, scientific research, etc., and we must give full play to the important role of governments at all levels in developing green agriculture in Northeast China. Make full use of the existing ecological advantages and plan and implement the "Green Agriculture Project". "Green agriculture project" refers to a systematic project centering on the production and marketing of green food, including the construction of ecological environment. Now people propose to build a "green northeast", which means to build the northeast into an industrial base for agricultural products, green products and traditional Chinese medicine. The important projects involved in the "Green Agriculture Project" here mainly include: agricultural and sideline products and green products processing base, Changbai Mountain specialty base, Beijing medicine base and so on. Local governments should implement specific construction projects according to local conditions, such as the construction of production bases, the construction of leading enterprises, the construction of market system, and the layout of industrialization. In order to promote the steady development of green agriculture industry in Northeast China, it is necessary to make long-term and short-term plans for developing green agriculture. Formulate policies that are inclined to the development of green agriculture and increase investment in agriculture. The government should be inclined to develop green agriculture when formulating policies. For example, the national policy of developing resource-based cities and regional connecting industries should be tilted to the northeast, increasing the central financial investment and long-term low-interest loans from the China Development Bank, and increasing the proportion of national infrastructure investment for the construction of "green agricultural projects", the regional development of connecting industries and the construction of resource-based cities. In this way, the green agriculture in Northeast China has been cultivated and set a good example for the whole country. Relying on scientific and technological progress to promote the development of green agriculture. Governments at all levels in northeast China should promote the in-depth development of green agricultural resources through scientific and technological progress, increase the scientific and technological content of green agricultural products brands and increase the added value of products; Transform and equip the traditional agricultural industry with high technology, realize the high technology of green agricultural industry, and then maximize the economic benefits. Improve the green food supply chain. From the structure of green food supply chain, green food production base is connected with logistics distribution center, and logistics distribution center is connected with supermarket chain monopoly. The key point here is that the logistics distribution center plays the role of a link between production and sales and is the key to the whole supply chain. From the current reality in Northeast China, both ends of the green food supply chain (production base and supermarket chain) have developed to a certain extent, but there is no stable and efficient logistics distribution center. Therefore, governments at all levels should create conditions for the market, vigorously develop logistics distribution centers and optimize the green food supply chain. At present, we should establish and standardize the logistics distribution center, establish and improve the supply chain management information system and improve the new product development mechanism.
