6. Types of organic farming <br>Finally, let's talk about the types of his model. There are basically three structures. One is the spatiotemporal structure, the other is the food chain type, and the last is the complex type. Spatio-temporal structure is a kind of organism based on a biological population. Agroecosystems, rationally created based on mutually beneficial symbiotic relationships between science, ecology, and biology, have biological populations with different ecological locations taking their place in the system. , Complement each other and allow you to maximize the use of solar energy, water and mineral nutrients. Three-dimensional structures with multiple time series and multiple levels in space have economic and environmental advantages. In particular, there are three-dimensional nesting models of orchards. A 3D model of farmland nesting, a 3D model of waters breeding, and a 3D model of farm planting and breeding. The structure of a food chain mainly refers to a favorable circulating agroecosystem, designed according to the laws of energy flow and the material cycle of the agroecosystem. Since the output of one production unit in the system is the input of another production unit, the waste in the system is recycled many times, which improves the energy conversion rate and resource utilization rate, and has great economic benefits. And agriculture is effectively prevented. Waste pollution from the agricultural ecological environment. In particular, this is a mode of internal processing of materials in crop production. Modes of internal treatment of materials in the breeding industry, modes of treatment of materials in a combination of planting, selection and treatment. The latter composite type is an organic combination of the above two, so the materials in the system can be efficiently produced and reused. This is a mode of modest input, high productivity, waste reduction, no pollution, high efficiency. type.<br>The importance of developing ecosystem agriculture is very important. The development of ecosystem agriculture can resolve the contradiction between the destruction of humans and nature. It is also a kind of life instinct that we create for better survival. This is our measure of salvation and has a deep natural meaning. The development of organic farming to optimize agricultural production models is also an inevitable manifestation of rapid economic development. Secondly, it can also increase the productivity and economic value of the land.
