Rice-crayfish-macrobrachium nipponensis comprehensive planting and breeding method

Abstract

The invention discloses a rice-crayfish-macrobrachium nipponensis comprehensive planting and breeding method. The rice-crayfish-macrobrachium nipponensis comprehensive planting and breeding method comprises the following steps that a rice field serves as a rice-crayfish-macrobrachium nipponensis co-cropping area, crayfish fry are stocked in February to March, and the crayfish fry are caught to appear on the market in May to June; rice is planted in the middle of June, after rice seedlings in the last ten days of June are dried in the sun, circular ditches around the rice field are cleaned and disinfected, and part of aquatic plants are transplanted; macrobrachium nipponensis offspring seeds are stocked in early July; mature rice harvested in late October; and the macrobrachium nipponensis is caught for sale in November. According to the rice-crayfish-macrobrachium nipponensis comprehensive planting and breeding method, on the premise that the rice planting area is not reduced, the rice-crayfish-macrobrachium nipponensis comprehensive planting and breeding mode is adopted, the time and space of the rice field are effectively expanded, and meanwhile, the comprehensive benefits of rice and fish planting and breeding are improved.

Description

technical field [0001] The invention relates to the technical field of comprehensive cultivation of aquatic products and agricultural products, in particular to a method for comprehensive cultivation and cultivation of rice-crayfish-Macrobrach japonicus. Background technique [0002] The comprehensive rice and fish farming model of "one water for two uses, one field for double harvest, stable grain and increased efficiency, win-win for grain and fish, and ecological protection" has increased farmers' income and made great contributions to ensuring food security and ecological security. The rice-fishing project is booming in the rural areas of our country, and has now formed a modern rice-fishing breeding industry with nearly 20 species of breeding objects and a planting area of ​​more than 34 million mu. The model of rice-fishing breeding is also constantly evolving. [0003] At present, the rice fish breeding industry mainly includes the following modes: (1) Symbiotic breed...

Problems solved by technology

However, in the above continuous cropping and symbiotic comprehensive planting and breeding models, different aquatic species cannot "peacefully coexist", which affects the breeding benefits
