Carp culture nanometer fertilizer

Abstract

The invention discloses a carp culture nanometer fertilizer. The carp culture nanometer fertilizer comprises, by weight, 2-4 parts of nitrogen-fixing bacteria, 1-3 parts of phosphate solubilizing bacteria, 3-5 parts of enzyme bacteria, 50-60 parts of fish meal, 75-80 parts of soybean meal, 20-30 parts of wheat bran, 70-80 parts of rice bran and the like. The carp culture nanometer fertilizer has the advantages that by the aid of the compound microorganism fertilizer, quick growth of carps can be promoted, the EPA (eicosapentaenoic acid) content can be increased, fish diseases and the quantity of fish died of diseases can be reduced, beneficial microorganisms in water can be increased, and the final quality of the carps can be improved.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a nanometer fertilizer for carp cultivation. Background technique [0002] Carp, also known as carp guaizi, belongs to Cyprinidae, Cyprinidae. There are many types, including wild carp and scale carp. Mirror carp, red carp, purse carp, etc. Carp has strong adaptability to the water body environment and is a traditional fine species of freshwater aquaculture in my country. Over the years, many domestic scientific research institutes have used new technologies to select and breed carp. Through methods such as domestication and hybridization, many fine varieties have been bred, and remarkable results have been achieved in fishery production in various places. Carp often inhabit the bottom of water bodies. Adult fish are omnivorous fish mainly molluscs. Under natural conditions, the main food is snails, clams, aquatic insect larvae, water earthworms and filamentous algae, aquatic plants ...

AI Technical Summary

Problems solved by technology

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

The microbial compound fish fertilizer can increase the content of beneficial bacteria in fish ponds and effectively reduce the occurrence of fish diseases. At present, there is no report on the special use of this compound microbial fish fertilizer
