What are the advantages and characteristics of ecological agriculture?

First, comprehensive. Ecological agriculture is supported by agricultural ecosystem. The overall biological yield of eco-agriculture is high, which stems from the reasonable and coordinated structure of eco-agriculture. The utilization of photosynthetic products in ecological agriculture is reasonable, which ensures the energy flow and material recovery in the system, arranges multiple cropping and intercropping, and improves the utilization rate of photosynthetic products of green plants. The comprehensiveness of ecosystem insists on taking agriculture as the center, and the coordination of ecological agriculture construction in China should be developed from household and village level to county level [4]. "County" is the most basic unit of China's administrative system and has relatively independent administrative and economic autonomy. From the administrative point of view, it has the right to use policies and other measures to mobilize its own financial resources and give play to its ability to adjust the eco-economic system, so as to realize the functions of economic scale and crisis sharing. From the planning point of view, the county seat is a natural group with a certain scale and characteristics, and it is a combination of macro and micro. It can design an optimized land use form according to the needs of farmers, and also set a reasonable per capita arable land area to effectively coordinate the rural working population. Realize the recycling of resources and the regeneration of energy, so as to achieve the purpose of adjusting the entire agricultural industrial structure.

Second, diversity. The ecological balance maintained by ecological agriculture is the best dynamic balance of spiral development. The difference between eco-agriculture and narrow-sense agriculture lies in: in terms of production content, it is not limited to planting, but diversified management of agriculture, forestry, animal husbandry and by-fishing, which develops in an all-round way. In the production area, it is not limited to cultivated land, but regards all the land as its own living place; It is not limited to grains, but scientifically arranges agricultural production based on nutrition and according to the quantity and proportion of heat energy (sugar, fat, etc.). ), protein, multivitamins and various minerals needed for human nutrition.

Third, efficiency. Through deep processing of materials and recycling of energy, eco-agriculture has improved farmers' value-added income, accelerated agricultural production efficiency and changed the local agricultural industrial structure. The core of eco-agriculture is science and technology, which can realize the value-added production of specific cash crops through the technical means of ecological model, balance the regional advantages of various regions with the technical means of ecological engineering, coordinate technology with social needs and local reality, give play to the adjustment ability of eco-economic system, realize the function of economic scale and crisis sharing, and form high economic benefits.
