Abstract

The invention provides a rice and shrimp co-culture ecological breeding method. According to the rice and shrimp co-culture ecological breeding method, ditches shaped like the Chinese character'tian 'are arranged, so that a breeding water body has good fluidity, submerged plants are planted in a shrimp pond, the dissolved oxygen content of the water body is further increased, and the survival rate of shrimp breeding is increased; shrimp larvae are processed with a nutrient solution before stocking, the shrimp larvae after transportation are helped to recover vigor, nutrition is supplemented, the shrimp larvae are made to adapt to culture conditions of a new environment, and the culture survival rate is increased; by continuously changing feed feeding points in the breeding period, swimming ingestion of the shrimps is effectively promoted, the physique and immunity of the shrimps are enhanced, the morbidity is reduced, and the breeding survival rate is increased; and with adoption of the ecological breeding method, the rice field can be fully utilized, high-quality adult shrimps can be obtained through breeding, and the economic benefits of breeding are increased.

Description

technical field [0001] The invention relates to the technical field of ecological planting and breeding, in particular to a rice-shrimp co-cropping ecological breeding method. Background technique [0002] At present, the status of fishery resources is not optimistic. Whether it is freshwater or seawater, China's aquaculture industry relies heavily on offshore fishery resources, showing a high-carbon, high-nitrogen, and low-quality production model. The traditional single-pond mouth regulates water ecology. Integrated mixed culture There is no room for large growth in model output, especially in the case of heavy pollution of external water quality, endogenous nutrition can no longer be effectively adjusted through polyculture, water quality is easy to deteriorate, and there is an urgent need for a sustainable ecological comprehensive farming model that complements different farming units . At present, effective rice-fishing co-cropping models in China, such as the rice-shr...
