Special compound microorganism fish fertilizer for carp and preparation method thereof

Abstract

The invention discloses a special compound microorganism fish fertilizer for carp and a preparation method thereof. The special compound microorganism fish fertilizer comprises the following components by weight: 2 to 4 parts of nitrogen-fixing bacteria, 1 to 3 parts of phosphate solubilizing bacteria, 3 to 5 parts of ferment bacteria, 50 to 60 parts of fish meal, 75 to 80 parts of a soybean cake, 20 to 30 parts of wheat bran, 70 to 80 parts of rice bran, 10 to 14 parts of brown sugar, 8 to 10 parts of yeast powder, 12 to 15 parts of salt, 80 to 85 parts of chicken manure, 60 to 65 parts of waterweed, 10 to 13 parts of calcium hydroxide, 15 to 20 parts of urea, 3 to 5 parts of potassium sulfate, 3 to 5 parts of ferric citrate, 0.2 to 0.4 part of vitamin B1, 0.1 to 0.3 part of vitamin B12, 1 to 4 parts of baical skullcap root, 3 to 5 parts of isatis root and 4 to 6 parts of liquorice. The compound microorganism fish fertilizer provided by the invention can promote rapid growth of fish, improve quality and quantity of fish, reduce fish diseases and allows beneficial microorganisms in water to be increased and growth of algae in a fishpond to be retarded.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a composite microbial fish fertilizer, in particular to a special composite microbial fish fertilizer for carp and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] The protein content of carp is not only high, but also of high quality. The human body's digestion and absorption rate can reach 96%. The food, and the method is various, deeply loved by the people. [0003] During the breeding process of carp, feed needs to be put in for its growth, but long-term feed feeding will breed some harmful bacteria in fish ponds and ponds. These harmful bacteria will not only affect the water environment, but also are not conducive to the growth of carp. And in the process of carp breeding, many farms currently use organic fertilizers to increase the production of carp by putting a certain amount of organic fertilizers in ponds; traditiona...

AI Technical Summary

Problems solved by technology

[0003] During the breeding process of carp, feed needs to be put in for their growth. However, if feed is put in for a long time, some harmful bacteria will grow in fish ponds and fish ponds. These harmful bacteria will not only affect the water environment, but also are not conducive to the growth of carp.

And in the process of carp breeding, many farms currently use organic fertilizers to increase the production of carp by putting a certain amount of organic fertilizers in ponds; traditional organic fertilizers have their advantages, but their disadvantages are single functions and are used by phytoplankton. The utilization process is long, and a large amount of oxygen in the water body is consumed during the mineralization process, which is unfavorable for the growth of stocking products in the water such as fish; in addition, organic fish fertilizers are suitable as base fertilizers, and are mainly used in winter and spring when the water temperature is low season

However, the function of inorganic fertilizer is relatively single. Although it can increase the yield of fish, long-term use of chemical fertilizer can bring many disadvantages, pollute the environment, and destroy the ecological balance.

[0004] In addition to single-function organic fertilizers and inorganic fertilizers, since the 1980s, "formula fertilization", that is, "organic-inorganic compound fertilizers", has been promoted. Although compound fertilizers have absorbed the advantages of both organic and inorganic fertilizers, But their shortcomings are not well overcome

The existing single-type fish fertilizer and compound fish fertilizer also have a common shortcoming, that is, they cannot kill harmful bacteria, so they lack the effect of effectively preventing and controlling fish diseases

The content of beneficial bacteria in fish ponds can be increased through microbial compound fish fertilizer, which can effectively reduce the occurrence of fish diseases. At present, there is no report on the compound microbial fish fertilizer specially used for carp
