Method of cultivating silver carps and bighead carps with organic fertilizer coordinated with biological fish fertilizer

Abstract

The invention discloses a method of cultivating silver carps and bighead carps with organic fertilizer coordinated with biological fish fertilizer. The method includes the steps that: (1) preparation of the organic fertilizer: A. Raw materials of the organic fertilizer are prepared: main materials, conditioners, fungicide and auxiliary agents; B. firstly, the conditioners are added to excrement of poultry and / or livestock, moisture humidity of the excrement is adjusted, then the auxiliary agents and the fungicide are added and mixed uniformly, and then mixture is stacked on a hardened ground or the mixture is placed in a fermentation machine for fermentation; C. the stacks are turned one time every day when the stacking temperature is above 50 DEG C, and thus the organic fertilizer can be obtained through fermentation and decay in 7-10 days; D. the decayed organic fertilizer is air dried, and thus the water content is lower than 30%, the decayed organic fertilizer is ground and packaged, and thus a finished product is obtained. (2) The stocking of the silver carps and the bighead carps is carried out. (3) Cultivation fertilization management and daily management are carried out. The method of cultivating the silver carps and the bighead carps with the organic fertilizer coordinated with the biological fish fertilizer has the advantages of being simple, easy to carry out, low in cost, good in economic benefit, economical and environment-friendly and scientific in waste using. The living environment of the bighead carps is improved and occurrence of diseases of the bighead carps is reduced.

Description

technical field

[0001] The invention belongs to freshwater fish culture technology, and in particular relates to a method for cultivating silver carp and bighead carp with organic fertilizer and biological fish fertilizer. Background technique

[0002] The technology adopted in the artificial breeding of large inland water surfaces (mainly referring to reservoirs and lakes) in my country is mainly silver carp and bighead carp, with moderate fertilization and timely fishing. Commonly known as silver carp, jumping silver carp, etc.), its ratio is as high as 80% to 90%, while the stocking ratio of bighead carp (commonly known as silver carp, big head carp, etc.) is extremely low, usually within 10%, and a few can reach 20%. This traditional stocking structure has resulted in silver carp being the main fish produced in inland large water surfaces, but the consumer market has a greater demand for bighead carp, and the contradiction between supply and demand is prominent, making th...
