Embodiment Construction

[0039] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with specific examples and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The rice-prawn co-cropping method of the present invention is divided into two parts, i.e. the cultivation of crayfish and the planting of rice.

[0041] Wherein, the culture of crayfish comprises the following steps:

[0042] 1. Rice field transformation

[0043] (1) trenching

[0044] That is, excavate a ring-shaped ditch along the outer edge of the paddy field ridge to 7m to 8m inside the paddy field. The foot of the embankment is excavated 2m away from the ditch, the ditch width is 3m~4m, and the ditch depth is 1m~1.5m. Among them, if the paddy field area reaches more than 50 mu, it is b...

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.
