Embodiment Construction

[0026] The purpose of the present invention is to provide a more effective rice-shrimp symbiosis breeding technology, which can increase the actual output of rice fields and increase economic benefits.

[0027] An escape wall was constructed in mid-March for 1 hectare rice field. By reinforcing the ridge, plastic film was laid along the ridge around the rice field, supported by wooden strips at 0.8m intervals, and fixed with iron wires; the height of the film on the soil was 40cm, and the underground was 20cm, slightly inward. Tilt to prevent crayfish from escaping along the current; splashing 2000kg / hm 2 Quicklime disinfects, kills enemies and germs, improves soil conditions, and stocks juvenile shrimp after 15 days. Choose to put shrimp seedlings at noon when the weather is fine in the first ten days of April. The stocking size is about 1.2cm, and 25,000 fish per mu; when the seedlings are released, the shrimp seedlings are disinfected, soaked in 4% light salt water for 5 minute...

Abstract

The invention relates to a rice and crawfish symbiotic artificial breeding technology. The technology includes the steps of constructing, cleaning and disinfecting of a paddy field for breeding juvenile crawfish; feeding and daily management of juvenile crawfish; capturing for selling. The rice and crawfish symbiotic artificial breeding technology can effectively improve the utilization rate of the rice field, achieves a rice and crawfish symbiotic system, improves the survival rate and the growth rate of crawfish in artificial breeding, increases yield, improves economic efficiency and promotes the development of crawfish breeding and rice farming.

Description

Technical field [0001] The invention relates to a rice-shrimp symbiosis artificial breeding technology, in particular to a breeding method that can complete the symbiosis and mutual benefit of rice and crayfish, and increase ecological efficiency, thereby improving economic benefits. Background technique [0002] Crayfish breeds fast, has a short breeding cycle, and at the same time has delicious meat, rich nutrition, and large market demand. It has broad development prospects and high economic benefits. It is widely found 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 planted in a wide area in my country. By transforming the fields, the rice-crab symbiosis model has been completed to achieve mutual benefit and a vi...
