Abstract

The invention discloses a high-activity and high-efficiency solid biological substrate-improving granule which comprises bacillus subtilis, denitrifying bacteria, clay, synergistic agents and wheat bran, and is characterized in that according to proportion by weight, 85 to 88 percent of clay, 1 to 2 percent of molasses, 1 to 2 percent of wheat bran, and 8 to 10 percent of bacillus subtilis and denitrifying bacteria are mixed to prepare a granular medicament. The high-activity and high-efficiency solid biological substrate-improving granule is a new composite microbial preparation design for excessive organic matters and high-content toxic substances such as nitrite, ammonia nitrogen, hydrogen sulfide and the like in aquaculture water, strains are domesticated and modified, an advanced production technology is adopted, and the activity is high and the marked effects are quick; and the product is made into a granule form through a special formula, and is rapidly dispersed within 5 minutes in the water, and can ensure that the product rapidly reaches the water bottom, so that the problem of worsening of water quality is basically solved. The invention provides a reliable guarantee for green ecological culture.

Description

technical field [0001] The invention relates to a solid particle of a biological modification preparation, in particular to a high-activity and high-efficiency solid biological modification particle. Background technique [0002] The aquaculture industry can be divided into marine aquaculture and freshwater aquaculture. During the long-term cultivation of these two types of aquaculture water bodies, the long-term contact between the mud bottom and marine excrement, residual bait, animal and plant residues, and nutrients in the water body itself, especially the contact with organic matter and microorganisms, has formed excessive Organic matter, nitrite, ammonia nitrogen, hydrogen sulfide and other toxic substances. [0003] Especially in freshwater fish farming, most of the land is ponds and factories. Since it is closed, the water body is in a state of static water for a long time. Therefore, it is necessary to remove organic matter, nitrite, ammonia nitrogen, and hydrogen ...
