Shrimp-rice co-culture breeding method

Abstract

The invention discloses a shrimp-rice co-culture breeding method. The shrimp-rice co-culture breeding method includes steps of (1), selecting lands; (2), transforming rice fields; (3), releasing juvenile shrimps; (4), constructing juvenile shrimp rearing sites; (5), carrying out feeding management in juvenile shrimp rearing phases; (6), carrying out adult shrimp breeding management; (7), cultivating rice; (8), sorting the rice fields; (9), sufficiently applying base fertilizers; (10), transplanting rice seedlings; (11), managing the rice fields; (13), draining water and carrying out harvesting. The shrimp-rice co-culture breeding method has the advantages that local rice field resources can be sufficiently utilized, and accordingly the shrimp-rice co-culture breeding method is low in cost;scientific and systematic management is carried out, and accordingly crawfishes can neatly grow and develop and are high in survival rate; the crawfishes and the rice are bred in a pollution-free manner, are high in quality and have high economic benefits; the development of the local crawfish breeding industry can be promoted; shrimp-rice system co-culture can be carried out, and accordingly theeconomic benefits can be obviously increased.

Description

technical field [0001] The invention relates to a breeding method for co-cropping shrimp and rice. Background technique [0002] Crayfish breeds fast, has a short breeding cycle, and at the same time has delicious meat, rich nutrition, large market demand, broad development prospects, high economic benefits, and widely exists in freshwater ponds in my country. However, due to serious water pollution, the quality of wild crayfish has been seriously affected; at the same time, overfishing of wild resources and backward artificial breeding techniques have caused the degradation of germplasm resources and the decline in production. Rice is widely planted in my country. By transforming the field, the co-cropping model of shrimp and rice has been completed to achieve mutual benefit and a virtuous circle, which has effectively improved the utilization rate of land and water resources. The social, economic and ecological benefits are very obvious. Shrimp Rice co-cropping technology ...
