Method for fish culture in paddy field

Abstract

The invention discloses a method for fish culture in a paddy field. The method is characterized by comprising the following steps of selecting the paddy field; planning the paddy field; planting rice;throwing in fries; carrying out feeding management; strictly controlling daily management and the like; and finally achieving a good ecological aquaculture mode of fat fishes and good rice. Accordingto the method, after the fishes are cultivated in the paddy field, a part or most of weeds, benthic animals, plankton and pests in the paddy field are eaten by the fishes, so that the harm to the rice is eliminated, and nutrients in the paddy field are not consumed by the creatures; in addition, faeces of the fishes provide high-quality manure for the growth of the rice, so that the ecological environment of the paddy field is improved, the rice yield is increased, the cultured fishes generally seldom suffer from diseases due to the fact that water of the paddy field is sufficient in dissolved oxygen, and relatively large economic benefits are conveniently achieved; and fish ditches and fish pits are reasonably designed and applied, so that the high-quality production of the rice and thefishes is improved, and a good harvest of both the rice and the fishes is achieved.

Description

technical field [0001] The invention relates to a method for raising fish, in particular to a method for raising fish in rice fields. Background technique [0002] Using the water surface of the rice field to raise fish can not only obtain fish products, but also use the fish to eat the pests and weeds in the rice field, excrete manure, turn the soil to promote the decomposition of fertilizer, create good conditions for rice growth, and increase rice production. Fish farming in paddy fields should focus on rice and fish farming. This guiding ideology is based on the theory of rice-fish symbiosis, using the artificially created symbiotic relationship between rice and fish to transform the original rice field ecology into a more favorable direction, so as to achieve the goal of increasing rice production and fish harvest. Rice field fish farming is a three-dimensional farming model that organically combines rice planting and fish farming in the same ecological environment. T...

AI Technical Summary

Problems solved by technology

However, the traditional fish farming in rice fields has problems such as blind fish farming, unreasonable rice planting density and fish stocking density, and improper application of pesticides and fertilizers. Although the pests are greatly reduced after rice field fish farming, they cannot be completely eliminated, and sometimes pesticides are still required. Insecticide, most pesticides are poisonous to fish, leading to rice root rot due to hypoxia, fish starvation and mass death, low quality of rice and fish, etc.
