Rice and lobster co-culture method

Abstract

A rice and lobster co-culture method includes a rice planting part and a lobster breeding part. The lobster breeding part includes the steps of (1) rice field modification; (2) juvenile shrimp culture; (3) adult shrimp breeding; (4) parent shrimp putting; (5) adult shrimp fishing, supplementary juvenile shrimp putting and parent shrimp retention. The rice planting part includes the steps of (1) rice cultivation; (2) rice field management; (3) field drying; (4) rice pest and disease control; (5) draining and harvesting. Compared with an ordinary rice and lobster co-culture mode, the morbidity frequency of lobsters can be reduced to 45 days or so from 7-10 days, the disease control cost is reduced by 150 yuan / mu or so, and the survival rate can be increased to 80% or above from 30-40%.

Description

technical field [0001] The invention relates to the technical field of crop planting and aquaculture, in particular to a method for co-culturing rice and shrimp. Background technique [0002] Rice-shrimp co-cropping belongs to a farming model that combines planting and breeding, that is, raising crayfish in rice fields and planting a season of mid-season rice. During the rice planting period, crayfish and rice grow together in the rice fields. At present, there are many patent documents disclosing different rice and shrimp co-cultivation methods. However, in practical applications, rice-shrimp co-cultivation has a greater risk of breeding. It is manifested in that in the current general rice-shrimp co-cultivation, the survival rate of crayfish is only about 30% to 40%. In a cycle (6-9 months), the incidence frequency is extremely high, reaching once every 7-10 days, and the cost of disease prevention and control is as high as 500-700 yuan / mu.
