Tablets for improving culture environment of culture pond and preparation method and application thereof

Abstract

The invention belongs to the field of aquaculture, and particularly relates to tablets for improving the culture environment of a culture pond as well as a preparation method and application of the tablets. The tablets comprise the following raw materials: a bacillus subtilis solid culture and a bacillus amyloliquefaciens solid culture, and further comprise the bacillus subtilis solid culture, thebacillus amyloliquefaciens solid culture, anhydrous sodium sulphate, sodium humate, dolomite powder, zeolite powder, maltodextrin and magnesium stearate. Research shows, in a process of preparing thetablets from the raw materials, a granulation process is not required, direct tabletting is performed, the oxidation-reduction potential and the dissolved oxygen at the bottom of the tank can be quickly improved; the sludge at the bottom of the pond is decomposed, residual feed, excrement, animal and plant corpses and organic chippings at the bottom of the pond are degraded, harmful substances such as ammonia nitrogen, nitrite, hydrogen sulfide and algal toxin at the bottom of the pond can be effectively adsorbed, the acidity of water is reduced, the pH value of the water is stabilized, microelements are supplemented, the transparency of the water is improved, and the purposes of improving substrate and purifying water are achieved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a tablet for improving the culture environment of a culture pond, a preparation method and an application thereof. [0002] The cultivation environment of the cultivation pond in the present invention includes but not limited to: the quality of the bottom of the cultivation pond and the quality of the water quality of the cultivation pond. [0003] The cultivation pond of the present invention includes a nursery pond and a growing pond. Background technique [0004] With the development of the breeding industry, drug feed additives such as antibiotics, olaquindox, quinolone, heavy metal elements (such as copper, zinc, etc.) are widely used in the world. Drug feed additives are very effective in preventing and treating diseases and promoting animal growth, but the resulting side effects and causing pathogenic bacteria to develop drug resistance, toxicity, and "thr...

AI Technical Summary

Problems solved by technology

Drug feed additives are very effective in preventing and treating diseases and promoting animal growth, but the resulting side effects and causing pathogenic bacteria to develop drug resistance, toxicity, and "three causes" (teratogenic, carcinogenic, and mutagenic) and other disadvantages have gradually emerged. , coupled with the fact that farmers put a large amount of chemical fertilizers into the water body and the discharge of domestic sewage and industrial wastewater, resulting in excessive nitrogen, phosphorus, and heavy metals. The eutrophication of lakes has far exceeded the capacity of rivers and lakes. Rivers and lakes Without a chance to recuperate, the aquatic ecosystem has been severely damaged
