Asian monsoon paddy field agriculture has the following characteristics: first, small-scale peasant management; Second, the output per unit area is high, but the commodity rate is low; Third, the level of mechanization is low; Fourth, the amount of water conservancy projects is large; Fifth, the technical level is low; Sixth, rich experience in planting.
Solution: increase investment in science and technology, moderately expand planting scale, etc. But now the ecological environment problems in Dongting Lake are serious, mainly including: 1, the secondary reclamation of farmland in the lake area is serious, and the trend of crop yield reduction is obvious; 2. The pollution load increases, which seriously endangers fishery production; 3. The wetland area is reduced, and biodiversity is threatened. I hope it can be handled as soon as possible: 1, returning farmland to lakes; 2. Prevention and control of water pollution; 3. control sediments.
