Problems solved by technology

However, there are many types of bacillus products on the market, the price is high, or the ingredients are single and the content of active ingredients is low, it is difficult to distinguish between good and bad
And the purchased Bacillus dry powder needs to be activated for more than 24 hours before it can be used, and the effect will be greatly reduced after 48 hours of activation, so it is not easy to store

Abstract

The invention discloses a method for culturing compound bacillus at a river crab culture pond opening, and a use method of the compound bacillus. The culture method comprises the steps of chlorine-removal, disinfection, preparation, aeration, stirring, inspection and the like. Excessive water rotifer is caused by fertilized water in the early stage of river crab culture, a large amount of oxygen and beneficial algae in water are consumed, and thereby ''white burning water'' is caused; at the same time, the excessive propagation of algae is caused by rotifer killing and the decomposition of a large amount of rotifer corpses, and thereby ''old green water'' is formed; and the ''white burning water'' or the ''old green water'' can reduce water body transparency, and influences the growth of waterweeds such as Elodea nuttallii and Hydrilla verticillata. Therefore, macromolecular organic matters in an early-stage water fertilizing agent can be quickly converted into nutritive salt which iseasily absorbed by algae by using the strong decomposition ability of the compound bacillus subjected to expanding culture in the early stage, so that the growth of the algae is promoted, and the water fertilizing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of compound bacillus culture, in particular to a method for cultivating compound bacillus at the mouth of a river crab culture pond and a method for using the compound bacillus. Background technique [0002] In recent years, the application of microbial preparations in river crab culture has become more and more common. By using microbial preparations to decompose the feces and residual bait of aquaculture organisms in the process of aquaculture, it is beneficial to adjust water quality factors and create a good environment for the growth of river crabs. Among them, Bacillus is favored by farmers because of its good stability, strong stress resistance and high survival rate. However, there are many types of bacillus products on the market, the price is high, or the composition is single and the content of active ingredients is low, so it is difficult to distinguish between good and bad. Moreover, the purch...
