Composite microbial preparation for promoting unshelling growth of aquatic crustacean, and preparation method and application method thereof

Abstract

The invention discloses a composite microbial preparation for promoting growth of aquatic crustacean shells. The composite microbial preparation is prepared from, by mass, 0.2 to 0.6 percent of bacillus megatherium, 0.5 to 1.5 percent of vitamin C, 4 to 12 percent of glucose, 0.5 to 1.5 percent of monocalcium phosphate, 10 to 20 percent of silicon-calcium-potassium-magnesium fertilizer and 70 to 80 percent of zeolite powder. The preparation method comprises the following steps: (1) respectively taking the components in proportion, and uniformly mixing to obtain a synthetic material; and (2) uniformly mixing with zeolite powder to obtain the compound microbial preparation. The application method comprises the following steps: (1) water quality regulation and splashing; and (2) splashing of the seedlings. Through ionization processing, the organic calcium and magnesium reach a good active state, the hydrolysis degree is high, and the organic calcium and magnesium are very easily absorbed and metabolized by aquatic crustacean; the shelling growth of the aquatic crustacean is quickly promoted; and active organic calcium, magnesium, phosphorus and various trace elements and mineral substances required by the growth of the crustacean are supplemented and maintained, and the effects of improving the physique and appearance of the aquatic crustacean, improving the commodity quality, improving the water quality and the like can be achieved after frequent use.

Description

technical field [0001] The invention relates to the field of microbial preparations, in particular to a preparation method and an application method of a composite microbial preparation for promoting shelling growth of aquatic crustaceans. Background technique [0002] Hard shell fungus is a giant bacillus extracted from the bottom mud of high-yield crustacean aquatic animal breeding ponds. After domestication, rejuvenation and cultivation, it is cultured by liquid fermentation and compounded with organic calcium that can be quickly absorbed and utilized by crustacean aquatic organisms. , magnesium and a variety of trace elements of the compound micro-ecological preparations. After this product is put into the water body, the phosphorus-solubilizing bacteria can convert the ineffective phosphorus in the pond sediment and organic matter into the available phosphorus available to aquatic crustaceans, so as to overcome the phosphorus limitation of high-density aquaculture ponds...

AI Technical Summary

Problems solved by technology

However, when aquatic crustaceans are cultured, due to poor water quality, aquatic crustaceans often cause symptoms such as soft shells and failure to shell due to lack of minerals, and often kill each other, and the survival rate of breeding is low
