Throughout Agroecology In the process of development, agriculture has probably gone through several stages: first, primitive agriculture, using simple tools such as stone tools and sticks to engage in simple agricultural activities; Second, the traditional agriculture based on manpower, animal power, hand tools and ironware is developed from the experience accumulated by several generations and dominated by self-sufficient natural economy; The third is to take traditional agriculture as the leading role. Modern agriculture is a modern agriculture developed by using modern science and technology, the means of production and scientific management methods provided by modern industry.
At present, China Agroecology The development stage is generally in the stage of modern agricultural development, but there is no lack of traditional agriculture in the vast mountainous areas, and the production efficiency is extremely underground. Therefore, China's agricultural development is a combination of modern and traditional development model.
In the development of modern agricultural ecology, people have achieved unprecedented development in agricultural production and grain output through the promotion and application of modern agricultural technologies such as pesticides, fertilizers and mechanization. However, the application and promotion of high-energy substances such as pesticides and fertilizers have begun to deplete resources, reduce soil fertility, affect the agricultural ecological environment, reduce the quality of agricultural products, and greatly affect human health.
