Embodiment Construction

[0026] The purpose of the present invention is to provide a more effective rice-shrimp symbiotic culture technology, increase the actual output of the paddy field, and improve economic benefits.

[0027] 1 hectare paddy field built an anti-escape wall in mid-March. By reinforcing the ridges, plastic films were laid along the ridges around the paddy fields, supported by wooden strips every 0.8m, and fixed with iron wires; Tilt to prevent crayfish from escaping along the water flow; splash 2000kg / hm 2 Disinfect with quicklime to kill predators and germs, improve soil conditions, and release juvenile shrimp after 15 days. Choose to release shrimp seedlings at noon when the weather is fine in early April. The stocking size is about 1.2cm, and 25,000 tails are released per mu; The juvenile shrimp will crawl into the deep water area by itself; the juvenile shrimp must have healthy limbs, a strong body, and no disease or injury. Start feeding after 3 days of stocking. Use special f...

Abstract

The invention relates to a symbiotic artificial breeding technology for rice and crayfishes. The symbiotic artificial breeding technology comprises the following steps of establishing, cleaning and sterilizing a rice field to carry out stocking of juvenile crayfish; carrying out feeding and daily management on the juvenile crayfish; catching and marketing. According to the symbiotic artificial breeding technology, the utilization rate of the rice field can be effectively improved, a symbiotic system for the rice and the crayfishes is implemented, the survival rate and the growth speed for artificial breeding of the crayfishes are improved, the yield is increased, the economic benefit is improved, and the development of crayfish breeding industry and rice planting industry can be pushed.

Description

technical field [0001] The invention relates to a rice and shrimp symbiotic artificial breeding technology, in particular to a breeding method capable of completing the symbiosis and mutual benefit of rice and crayfish and ecological synergy, 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, 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 fields, the symbiosis model of rice and crabs is completed to achieve mutual benefit and a virtuous circle, which ...
