Rice and shrimp breeding and breeding separation efficient comprehensive planting and breeding method

Abstract

The invention discloses a rice and shrimp breeding separation efficient comprehensive planting and breeding method, which comprises the following steps: S1, field engineering standardization transformation: selecting a field with sufficient water source, excellent water quality and convenient irrigation and drainage to carry out rice and shrimp comprehensive planting and breeding, the area of a single field is preferably 20-60 mu, the field is rectangular, and the length-width ratio is 2: 1; the water inlet system is an open channel, the depth is 50cm, the bottom width is 30-40cm, and the section of the cement slope protection is trapezoidal; s2, green cultivation of rice: raising seedlings from late May to early June, and transplanting in mid-to-late June; base fertilizer is mainly applied, and 100-150 kg / mu decomposed manure and 15-20 kg / mu compound fertilizer are used as the base fertilizer; s3, accurately and efficiently culturing the crayfishes: promoting the crayfishes to mate in advance, lay eggs, incubate and grow juvenile crayfishes through a method at least comprising the steps of erecting a sunshade net for cooling, drying a field or pond to fortify parent crayfishes to live in holes, returning water and planting grass, and increasing nutrition; according to the method, the purpose of continuously producing large-size crayfish is achieved by adopting a breeding mode of rice and crayfish breeding separation and stubble rotation field cleaning, the market competitiveness of the crayfish is high, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-efficiency comprehensive planting and breeding method for rice and shrimp breeding and separation. Background technique [0002] Crayfish (scientific name Crayfish) belongs to Arthropoda, Crustacea, Crayfish family, Procrayfish genus. Its meat is delicious and nutritious, and it is deeply loved by people. It is the main species of shrimp farming. In recent years, due to the sharp increase in market demand, the natural resources of crayfish have decreased sharply, and the price has gradually increased. Therefore, scientific breeding is used to meet the market demand. [0003] The cultivation of freshwater crayfish in the paddy field is a business model that utilizes the shallow water environment of the paddy field and supplemented by artificial measures to grow both rice and shrimp to improve the benefit per unit area of ​​the paddy field. The introduction of crayfish ...

AI Technical Summary

Problems solved by technology

In the next breeding cycle, crayfish will multiply in large numbers, and the density of breeding seedlings will be too high, which will lead to small size of crayfish, poor overall quality, no market competitiveness, and reduced economic benefits; , the crayfish caught up, due to staying in the ground cage for a long time, the space of the ground cage is small, and lack of oxygen, so these crayfish are facing dehydration and extrusion damage, after being put back into the water, the stress injury It is very large, and the survival rate is actually very low. In addition, frequent use of ground cages will also cause the crayfish in the water to be in a state of stress for a long time, resulting in slower growth
