A compound system for planting and breeding in paddy fields and fish ponds

Abstract

The invention relates to a paddy field and fish pond planting and breeding complex system, which belongs to the technical field of comprehensive utilization of agricultural ecological aquaculture. The composite system includes rice fields, fish ponds, simple ecological ditches and enhanced ecological ditches. There is a rice field at one end of the fish pond, and a strengthened ecological ditch and a sump are provided on one side of the fish pond and the paddy field. A simple ecological ditch is provided in the paddy field, and a small overflow is provided on the simple ecological ditch. The rice field passes through a large overflow and the sump. Connected, the fish pond is connected with a simple ecological ditch through a pump. The invention organically combines rice field planting and fish pond cultivation through ecological ditches, and realizes a new mode of circulating water species cultivation in which fish pond cultivation water is purified through rice fields and ecological ditches and then returned to fish ponds. It solves the problems that rice-fish contradictions exist in the production process of the existing rice-based planting and breeding mode, such as drying the field, fertilizing, and pest control, and the output is limited, which is not convenient for large-scale promotion.

Description

technical field [0001] The invention relates to a paddy field and fish pond planting and breeding complex system, which belongs to the technical field of comprehensive utilization of agricultural ecological aquaculture. Background technique [0002] Traditional paddy-fish farming is a rice-fish production method in which fish ditches and fish slides are excavated in paddy fields for fish farming. Its remarkable advantage is that fish can be raised on the water surface of rice fields, which can not only obtain fish products, but also use fish to eat pests and weeds in rice fields, excrete manure, turn soil to promote fertilizer decomposition, and create good conditions for rice growth. Increase production by about 10%. This rice-based farming model also takes fish farming into account. In the actual production process, there are contradictions between rice and fish such as shallow irrigation, drying the field, fertilizing, and pest control. At the same time, the production o...

Problems solved by technology

This rice-based farming model also takes fish farming into account. In the actual production process, there are contradictions between rice and fish such as shallow irrigation, drying the field, fertilizing, and pest control. At the same time, the production of catches is limited, and the average average fish yield per mu is about 50 kg.
