Problems solved by technology

However, the current paddy farming methods and models are improper, and the crayfish produced are generally small in size, poor in color and have many diseases, which affects the survival rate and yield of crayfish, and cannot guarantee farmers to obtain corresponding economic benefits.
In addition, because the crayfish cultured in rice fields are fed with artificially compounded feed, the taste and nutrition of the crayfish produced are poor, and the nutrition of the natural crayfish cannot be achieved.

Embodiment 1

[0022] A kind of shrimp-rice symbiotic culture method, comprises the following steps:

[0023] 1) Selection and transformation of paddy fields: select paddy fields with sufficient water sources, no pollution of water bodies, no drying up in dry seasons, no flooding in rainy seasons, good water retention performance, loamy soil, fertile bottom and no silting, and excavate circular shrimp breeding ditch around the paddy fields. Make the center of the paddy field form a rice planting area, the bottom of the ditch is 3.5m wide, the ditch is 0.8m deep, and the slope is 45 degrees. Use the excavated soil to make a ridge along the periphery of the shrimp breeding ditch. The ridge is 0.5m high and 1.5m wide. Wide dense mesh or asbestos tile fence, the lower end of the mesh is buried in the soil 20 cm, the upper part of the soil is 40-50 cm higher than the field ridge, and slopes inward at 90 degrees; the transformed rice field, shrimp farming ditch and rice planting The area ratio of ...

Embodiment 2

[0033] 1) Selection and transformation of paddy fields: select paddy fields with sufficient water sources, no pollution of water bodies, no drying up in dry seasons, no flooding in rainy seasons, good water retention performance, loamy soil, fertile bottom and no silting, and excavate circular shrimp breeding ditch around the paddy fields. Make rice planting area in the center of paddy field, ditch bottom width 4m, ditch depth 1.2m, slope 55 degrees, use the excavated soil to make ridge along the periphery of shrimp breeding ditch, ridge height 0.6m, width 2m, use 70 cm wide on the ridge Dense mesh or asbestos tile fence, the lower end of the mesh is buried in the soil 20 cm, the upper part of the soil is 40-50 cm higher than the field ridge, and is inclined inward at 90 degrees; the rice field after transformation, the shrimp breeding ditch and the rice planting area The area ratio is 1:4; after the paddy field is transformed, inject water and fertilize in the ring-shaped shri...

Abstract

The invention discloses a crayfish and rice intergrowth cultivation method. The method comprises rice field selection and improvement, disinfection, crayfish fry throwing, crayfish feeding, rice planting and adult crayfish fishing. The crayfish and rice are in a reciprocal symbiosis relation, the crayfish loosens soil for the rice and eliminates insect pests, the rice has the characters of absorbing N, P and other nutrient elements in a water body, has the shading function, purifies the cultivation water body and also provides an inhabiting and hiding place for the crayfish, a good growth environment is created for the crayfish, and the crayfish cultivation product quality is improved. The cultivated crayfish is fast in growth and tidy in specification while normal production of rice is not influenced, one field has two purposes, the crayfish and the rice are both harvested, and benefits are greatly increased.

Description

technical field [0001] The invention relates to a method for cultivating crayfish, in particular to a method for cultivating symbiotic crayfish and rice. Background technique [0002] Procambarus clarkii belongs to Arthrophyta, Crustacea, Procambarus genus, also known as crayfish, scientific name Procambarus clarkii (hereinafter collectively referred to as crayfish), its delicious meat, rich nutrition, loved by people, is currently the 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, artificial scientific breeding is used to meet market demand. In order to consider economic benefits, the scale and area of ​​rice field comprehensive interbreeding are currently increasing rapidly. However, the current paddy farming methods and models are improper, and the crayfish produced are generally small in size, poor in color and ha...
