Aquaculture microorganism substrate improver having triplet efficacy and preparation method thereof

Abstract

The invention discloses an aquaculture microorganism substrate improver having a triplet efficacy and a preparation method thereof. A high viable content can still be kept in the production and transportation process, and the effect of the viable content can still be efficiently played under a low-oxygen-solubility condition on the bottom of a pond. Organic substances such as bait residues and manure can be decomposed, and the pathogenic microorganism can be inhibited; organic phosphorus in the water is converted into inorganic phosphorus, and the growth of phytoplankton is promoted; nitrite nitrogen in the water is converted to nitrogen to removal water, so that the content of the water nitrite nitrogen is reduced; and heavy metal ions are chelated, so that the toxicity of heavy metal is reduced, a triplet efficacy of bottom improvement, water regulation and detoxication can be realized, and the water environment is comprehensively improved. The aquaculture microorganism substrate improver is prepared from the following components in parts by weight: 1 to 3 parts of zeolite powder, 2 to 8 parts of bentonite, 0.5 to 4 parts of diatomite, 1 to 3 parts of polyglutamic acid powder, and 2 to 8 parts of composite probiotics powder.

Description

technical field [0001] The invention belongs to the technical field of in-situ restoration of aquaculture water environment. In particular, it relates to an aquaculture microbial substrate improver with triple functions. Background technique [0002] The rapid development of intensive aquaculture has brought new problems while improving economic benefits. Under the high-density breeding mode, the pollution of the breeding water itself is very serious. Research by many scholars has shown that the utilization rate of bait in the breeding process is low. During the breeding process, a large amount of residual bait, biological metabolites, animal and plant carcasses and other organic matters accumulate at the bottom of the breeding pond. These organic matters will be decomposed and decomposed under the action of anaerobic bacteria to produce a large amount of substances that are toxic to aquaculture animals, resulting in physical and chemical changes in the aquaculture water.

Problems solved by technology

Among them, lactic acid bacteria cannot form spores, and their resistance to stress is poor. They are easily inactivated during the production and storage of bottom modification, and the actual application effect is poor.

Although the aerobic bacillus has strong stress resistance, the low dissolved oxygen environment at the bottom of the single aquaculture pond will inhibit the proliferation of such microorganisms, thereby affecting its use effect

Moreover, the current bottom improvement products have a single function, and cannot improve the water quality and bottom environment of aquaculture three-dimensionally.
