Special nano slow-release fish guano for silver carps and preparation method thereof

Abstract

The invention discloses a special nano slow-release fish fertilizer for silver carp and a preparation method thereof, wherein a compound microbial fish fertilizer special for silver carp comprises the following ingredients in weight ratio: 0.5-0.8 part of silicate bacteria, 1 part of streptococcus faecalis -3 parts, 0.6-0.8 parts of Trichoderma, 2-5 parts of Rhodopseudomonas palustris, 0.3-0.5 parts of yeast, 50-60 parts of fish bone meal, 65-70 parts of vinegar grain powder, 50 parts of waste liquid sediment 55 parts, rice bran 40-60 parts, etc. The invention can promote the rapid growth of silver carp, increase the EPA content of fish body, reduce fish diseases, reduce sick and dead fish, increase beneficial microorganisms in water body, and finally improve the quality and quality of silver carp.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a composite microbial fish fertilizer, in particular to a special nano slow-release fish fertilizer for silver carp and a preparation method thereof. Background technique [0002] Silver carp can provide rich glial protein, which can not only keep fit, but also beautify the skin. It is an ideal food for women to nourish the skin; it has curative effects on rough skin, desquamation, and brittle and easy to fall off hair. Delicacy; it is a health-preserving food for warming the middle and invigorating Qi, warming the stomach, and moisturizing the skin. It is suitable for people with spleen and stomach deficiency, loose stools, and dry skin. It can also be used for symptoms such as insufficient milk caused by spleen and stomach Qi deficiency. It is a very popular fish. one of the classes. [0003] During the breeding process of silver carp, feed needs to be put in for its growth, but long-...

AI Technical Summary

Problems solved by technology

The prevention and treatment of these diseases is generally based on drug treatment, but long-term drug use can make the fish resistant to drugs, and some drugs can accumulate in the fish body, which is harmful to the human body

[0004] 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 process of mineralization is relatively 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 such as fish in the water

[0005] 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 special nano slow-release fish fertilizer specially used for silver carp and its preparation method
