Advantages of pond-based agriculture

Sangji fish pond type" in many southern rural areas is very consistent with the long-term development of the economic field and to ensure that the environment is not polluted. It is characterized by the fact that farmers utilize the principle of mutualism of organisms to establish the ecosystem of the pond. They dug ponds to raise fish, planting mulberry on the pond surface, using mulberry leaves to raise silkworms, and then use silkworm sand to feed the fish, containing fish droppings in the pond mud as fertilizer to return to the pond base, forming a closed ecological chain, known as the "mulberry-based fish ponds type". In this food chain, the mulberry tree is the producer, the silkworm is the primary consumer, the fish is the secondary consumer, and the microorganisms in the fish pond are the decomposer, in which the material is recycled over and over again and endlessly, and the waste is fully utilized. This mode of production, as far as its characteristics are concerned, is in line with the spirit of eco-agriculture.

This model practically organizes agricultural production according to the principles of ecology, makes full use of local natural resources, takes advantage of the interdependence between animals, plants, and microorganisms, carries out waste-free production, provides as many clean products as possible, makes effective use of mechanical equipment, fertilizers, and pesticides while minimizing their polluting impacts, and also fully absorbs the experience of traditional agriculture in an effort to achieve the greatest green vegetation, highest biological yield, the most rational photosynthesis, the best economic benefits, the best ecological balance and other goals.

Eco-agriculture is different from organic agriculture in that it does not exclude chemical substances such as fertilizers, pesticides, herbicides, etc., so it may achieve higher yields. It is also different from petroleum agriculture, that is, pay more attention to the ecological balance, so that the mountains, water, field comprehensive use, in the fertilizer on the importance of organic fertilizers, in the control of pests and diseases pay attention to biological control and integrated control, reduce the pollution of pesticides. So most of China's agricultural scientists believe that China's agricultural modernization only take the road of ecological agriculture, in order to avoid a series of problems of petroleum agriculture, in the output of a large number of high-quality products at the same time, can also be expected to establish a beautiful and pleasant environment.

With the development of science, modern agriculture is constantly transitioning to a more advanced and improved direction. It can be predicted that this evolution will certainly change the face of the whole society greatly.
