Problems solved by technology

However, Bacillus subtilis is an aerobic microorganism, which consumes dissolved oxygen in water during use. Improper or excessive use can easily cause hypoxia in the water body, and even cause the death of farmed animals.
The current Bacillus subtilis preparations in the industry are generally liquid preparations or solid powders. In actual use, they are put into the aquaculture water body at one time according to the dosage of the preparation product instructions. After Bacillus subtilis enters the water body, because of its short generation cycle, The proliferation speed is fast, which can easily lead to sudden hypoxia in the aquaculture water, thereby causing the death of the aquaculture animals; in addition, liquid or solid Bacillus subtilis preparation products generally need to be activated for 1 to 2 hours before use, which is also difficult for users when using. Inconvenience

Abstract

Relating to the technical field of water environment improvement and repair in aquaculture, the invention provides a compound bacillus subtilis sustained-release tablet, which comprises, by weight: 2-9% of bacillus subtilis raw powder, 73-96% of sodium percarbonate, 1-10% of a sustained release agent, and 1-8% of a stabilizer. The invention aims to provide the compound bacillus subtilis sustained-release tablet. The product has a significant improvement effect on the culture water environment, is convenient to use, and avoids the problem of culture water oxygen deficiency.

Description

technical field [0001] The invention relates to the technical field of improvement and restoration of aquaculture water environment, in particular to a compound Bacillus subtilis slow-release tablet. Background technique [0002] With the rapid development of the aquaculture industry and the continuous increase of the breeding density, the residual bait, feces, and animal and plant corpses in the water continue to accumulate, resulting in more and more serious pollution of the aquaculture water body. Excessive organic load in aquaculture water will cause deterioration of water quality and lead to breeding of animal diseases and even death. Therefore, the pollution and deterioration of the aquaculture water environment has become the main factor restricting the development of aquaculture industry, and also restricts the development of my country's fishery economy. Especially when vigorously promoting healthy farming and producing pollution-free aquatic products, the preventi...
