Embodiment 1

[0014] A method for cultivating koi in a rice field, the steps of which are:

[0015] (1) Preparatory work before breeding: select a paddy field with sufficient water source, good water quality, and strong water retention. "type, so that all waters are connected, the area of ​​the fish ditch is 10%-15% of the paddy field area, and the depth of the center and four corners of the paddy field is 1m, and the area is 10m 2 Heighten each field ridge to 60cm, widen to 40cm, and tamp the field ridge; remove excess silt, eradicate weeds, and sprinkle with 60kg quicklime per mu; inject new water, pH value 7-8, Dissolved oxygen 3.5-6mg / L; ensure sufficient sunlight and a quiet environment; install anti-escape nets and filtering facilities at the inlet and outlet, and also have anti-bird nets and sunshade nets;

[0016] (2) Transplanting seedlings and releasing seedlings: rice seedlings should be selected with hard straw and lodging-resistant varieties. Before rice planting, apply suffic...

Abstract

Disclosed is a method for raising koi carps in a paddy field. The method comprises the following steps of 1, preparatory work before raising; 2, seedling transplanting and fry putting; 3 stocking density and feeding modes; 4, fry selection and netting exercise; 5, daily management; 6, disease control and treatment. According to the method for raising the koi carps in the paddy field, through paddy rice variety selection, fertilizer selection and other treatment in the early period, the paddy field is not only suitable for the growth of paddy rice but also conducive to the growth of the koi carps; water disinfection and fertilization are conducted in the preliminary period, so that fry are located in a healthy growth environment and are fed with sufficient feed, and the survival rate of the fry in the preliminary period is increased; by the adoption of raising management such as stocking density and feeding screening methods in the later period, the koi carps grow quickly, strong individuals with bright colors and luster are selected, and the incidence rates, mortality rates and the like of paddy rice and koi diseases are reduced by using low-toxicity pesticides and biological agents, the growth efficiency is improved, and the economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of brocade carp cultivation, in particular to a method for cultivating brocade carp in paddy fields. Background technique [0002] At present, in order to improve economic benefits and make full use of land resources, the method of cultivating koi in rice fields is adopted to improve economic benefits. However, in the process of raising, there is no scientific and rational feeding management method, which greatly reduces the benefits of cultivating koi in rice fields. The present invention aims at providing a systematic cultivation and management method for breeding koi in rice fields, reducing the mortality and disease rate of koi, making the koi grow rapidly and improving economic benefits. Contents of the invention [0003] The present invention provides a method for cultivating koi in paddy fields in order to achieve the above object. [0004] The technical scheme that the present invention takes: ...
