Rice and crayfish rotation ecological breeding method

Abstract

The invention discloses a rice and crayfish rotation ecological breeding method. The method comprises the following steps of 101, field transformation, 102, irrigation, 103, aquatic plant planting, 104, crayfish fry stocking, 105, water level control, 106, adult crayfish fishing, 107, rice planting and 108, rice harvesting. According to the symbiotic complementation principle between animals and plants, a substance circulation system in the nature is utilized, rice serves as a main part through a corresponding planting and breeding technology, and the problems that in an existing rice and crayfish symbiotic technology, crayfish and rice compete for land, the variety is degenerated, and the quality is reduced are solved.

Description

technical field [0001] The invention belongs to the technical field of storage and transportation of crayfish, and in particular relates to a live freezing method for convenient storage and transportation of red crayfish. Background technique [0002] With the deterioration of the rice planting environment, the occurrence of diseases, insect damage and weed damage is becoming more and more serious. In traditional production, chemical fertilizers and pesticides are widely used, which not only brings hidden dangers to the consumption of rice, but also causes environmental pollution due to large amounts of fertilizers and pesticides. The country requires straw to be returned to the field. Straw rots and ferments in the soil. During the fermentation process, a large amount of hydrogen sulfide gas is produced to erode the roots of rice, causing poor development of rice roots and insufficient tillering, resulting in reduced yield. At the same time, insect eggs live on straw, which...

AI Technical Summary

Problems solved by technology

[0004] In the traditional rice-shrimp co-cropping mode, trenches need to be dug in the field, and only a small planting area is reserved. There is a problem of land competition between shrimp and rice. At the same time, it is more troublesome to harvest rice in the later stage, which changes the basic farmland of the field. Attributes that affect staple food security

[0005] At present, the methods and models of paddy field farming are improper, and the crayfish produced are generally small in size, poor in color, degraded in variety, and have many diseases. Poor, not up to the nutrition of natural crayfish

At the same time, the yield of rice is low and the quality is average.
