Problems solved by technology

[0004] The purpose of the present invention is to: provide a kind of by establishing rice field integrated planting and breeding ecological system, make crayfish fully utilize the biological bait resource in the paddy field, achieve rice and shrimp co-growth, solve existing paddy planting and use pesticide, chemical fertilizer not only pollute the environment, At the same time, it also affects people's health, as well as the overfishing of wild crayfish resources and backward artificial breeding technology, causing the degradation of germplasm resources and the decline of production; the rice shrimp of one season of rice and three seasons of shrimp to achieve the purpose of maintaining ecological balance and improving the efficiency of planting and breeding nesting symbiosis method

Embodiment Construction

[0023] Excavate circular ditches around the farmland with an area of ​​50-60 mu, and bury water inlet pipes at intervals on the annular ditch at one end of the farmland, and bury drainage pipes at intervals on the annular ditch at the other end of the farmland. The level of the water inlet pipes is higher than that of the drainage pipes to achieve the purpose of high irrigation and low drainage; at the same time, a culvert is laid on the annular ditch on one side of the farmland in the form of buried culverts, so that the agricultural machinery and tools can enter the farmland; the opening of the annular ditch is 4-5 meters, the bottom The width is 1 meter, the depth is 1.5 meters, and the slope ratio of the annular ditch is 1:2.5-1:3; the width of the embankment of the annular ditch is 3-3.5 meters, so as to prevent the crayfish from digging holes to penetrate it during the breeding process.

[0024] Rotary plowing and drying of the farmland begins in late May every year, and ...

Abstract

The invention relates to a rice-shrimp intercropping symbiotic method of single-season rice and three-season shrimps, and belongs to the technical field of ecological planting and breeding. The method comprises the steps of digging a circular furrow at the periphery of a farmland with the area of 50-60 mu, and then planting rice and water weeds in the farmland in the water weeds in an interval manner. Through building a rice field comprehensive planting and breeding ecological system, biological bait resources in the rice field can be fully utilized, the rice and the shrimps grow together, and the problems that a lot of pesticide is used for rice planting, environment is polluted by fertilizer, people health is also influenced, genetic resources are degenerated and yield is decreased due to overfishing of wild crayfish resources and backward artificial breeding technology are solved. The purposes of keeping ecological balance and increasing planting and breeding benefits are achieved.

Description

technical field [0001] The invention relates to a symbiosis method for intercropping of rice and shrimp for one season of rice and three seasons of shrimp, which belongs to the technical field of ecological planting and breeding. Background technique [0002] Simple rice planting has low economic benefits, and chemical fertilizers need to be applied during the planting process, which increases the cost of planting, and in order to prevent the occurrence of diseases and insect pests, a large amount of pesticides need to be used. Pesticide pollution has been quite serious; the use of a large number of pesticides and chemical fertilizers not only pollutes the environment, but also affects people's health, and can also cause problems such as soil compaction and deterioration of soil physical and chemical properties. [0003] Due to fast reproduction, short breeding cycle, delicious meat, rich nutrition, large market demand and high economic benefits, crayfish has broad developme...
