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

Abstract

The invention provides a method for fish culture in a paddy field, and belongs to the technical field of agricultural cultivation. The method comprises the following steps of 1) preparing the paddy field; 2) transforming the paddy field; 3) preparing fish culture facilities; 4) transplant rice seedlings; 5) carrying out biological adsorption; 6) carrying out paddy field disinfection; 7) carrying out irrigation and fertilization; 8) selecting stocking fingerlings; 9) carrying out stocking fry disinfection; 10) carrying out stocking; and 11) carrying out feeding management. According to the method, heavy metals in soil and irrigation water of the paddy field are absorbed by adopting a bio-adsorbent, most of the heavy metals in the soil and the irrigation water can be adsorbed, the pollutionof the heavy metals in the soil and the irrigation water in the paddy field is obviously reduced, and the contents of the heavy metals such as plumbum and cadmium in cultured fishes and in rice produced by rice planting are very low and are far lower than the national standard; and on the other hand, the bio-adsorbent is prepared from waste silk frigon and activated carbon, the adsorption cost islow, the source is extensive, the cost is low, and no damage is caused to human and the ecology.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding, in particular to a method for raising fish in paddy fields. 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 fi...
