Ecological fish farming method in rice field and ecological rice produced by rice plants

Abstract

The invention discloses an ecological fish farming method in a rice field, which comprises the following steps of rice field preparation, rice field transformation, fish farming facility preparation, rice seedling transplantation, biosorption, rice field disinfection, irrigation, fertilization, stocking fish seed selection, stocking fish fry disinfection, stocking and feeding management, wherein annular field fish ditches dug through the rice field transformation are V-shaped ditches arranged on the inner sides of ridges around the rice field; the biosorption utilizes a biosorption agent to adsorb heavy metal in rice field soil and irrigation water; and stocking fish seeds are selected from eight-beard catfishes. The invention further discloses rice produced by rice plants planted in the rice field using the ecological fish farming method. According to the method and the rice, an effective usable area of the rice field is increased significantly; pollution of the heavy metal such as lead and cadmium is reduced; integral benefits of fish farming in the rice field are improved; the ecological rice contains rich protein, more microelements such as iron, magnesium and calcium, and vitamin C, has no chemical pesticide residual, and is green and environment-friendly; and the content of the heavy metal such as lead and cadmium is very low.

Description

technical field [0001] The invention relates to a method for raising fish in a paddy field and the rice produced by the planted rice. Background technique [0002] Rice field fish farming refers to a production method in which rice and fish are grown in the same paddy field, so that the planting industry and aquaculture industry are skillfully combined. In a similar environment, the rice and fish are symbiotic and mutually beneficial, and a production method is used to improve the overall efficiency of the rice field. . The method for raising fish in rice fields in the prior art comprises the following steps: preparation of rice fields, transformation of rice fields, preparation of fish farming facilities, transplanting of rice seedlings, disinfection of rice fields, irrigation, fertilization, selection of stocking fish species, disinfection of stocking fish fry, stocking, and feeding management, wherein : Paddy field reconstruction is to excavate the fish ditch around the ...

AI Technical Summary

Problems solved by technology

The rice field fish farming method in the prior art can realize the symbiosis and mutual benefit of rice and fish, and improve the overall benefit of the rice field, but there are the following defects: the fish ditch around the field dug during the transformation of the paddy field occupies a large area of ​​the paddy field, reducing the effective use area of ​​the paddy field ; The content of heavy metals such as lead and cadmium in the finished fish and rice produced by planting rice exceeds the standard, which is neither green nor environmentally friendly; The sales price is not high, which also affects the overall benefits of rice field fish farming
