Method for cultivating fish in organic rice field

Abstract

The invention discloses a method for cultivating fish in an organic rice field. The method includes the selection of a rice field, wire drawing and ridging, planting and management of organic rice, the feeding and management of fries, the control of water, the prevention and control of pests and diseases and the fishing. According to the method, by optimizing a three-dimensional environment, the organic rice is planted in ridges, and organic fish are cultivated in furrows. The method is easy to implement, the soil structure of the organic rice field can be effectively protected without deep ploughing, and the continuous production capacity of the rice field is ensured; the labor cost can be reduced, the method reduces the mechanical cost per mu by 700-1000 yuan compared with a method of opening #-shaped and cross deep furrows, 3-3.5 workers are used per mu by manual ridging with a labor cost of 300-350 yuan, and the cost is effectively reduced by 50% to 66.7%; at the same time, field operations such as rice transplanting and weeding are more convenient, and management is facilitated.

Description

technical field [0001] The invention relates to the field of ecological aquaculture, in particular to a method for raising fish in an organic rice field. Background technique [0002] Fish farming in rice fields is to stock fish fry and grow together with rice in rice fields after transplanting rice seedlings to achieve a double harvest of rice and fish. It is a three-dimensional agricultural production model that integrates planting and aquaculture. Grass, devouring rice pests, reducing the use of pesticides, and at the same time, some organic matter produced by the growth and respiration of rice fields can be used as food for fish to achieve mutual benefit. This technology is an efficient and economical technical method for the scientific development and utilization of high-quality agricultural resources at the end of the 20th century. . With the rapid development of organic agriculture, the organic rice industry is in the ascendant, and has attracted people's attention a...

Problems solved by technology

However, it has been found in practice that the defects of this method mainly include three aspects: one is that the soil structure of the organic rice field is destroyed, the raw soil at the bottom of the plow with deep furrows is turned over to the field surface, and the fertility of the topsoil layer decreases, which is not conducive to the growth of organic rice seedlings. The production of organic rice is reduced; the second is high production costs, the cost of machinery for opening "well-shaped" deep trenches is 900-1000 yuan per mu, and the cost of machinery for opening "cross-shaped" deep trenches is 700-800 yuan per mu; the third is field operations Inconvenient, the paddy fields are artificially divided into blocks by deep ditches, and field operations such as transplanting seedlings, weeding, and guarding are not only safety hazards, but also inconvenient to operate
