Water quality improvement agent for aquaculture and preparation method thereof

Abstract

The invention discloses a water quality improvement agent for aquaculture and a preparation method thereof. The water quality improvement agent is prepared from the following raw materials according to the weight: 150 to 200g of molasses, 30 to 50g of catalase, 20 to 30g of bacillus subtilis, 50 to 70g of DL-malic acid, 60 to 80g of citric acid, 80 to 100g of urea, 60 to 100g of potassium dihydrogen phosphate, 50 to 70g of chitosan, 50 to 80g of zeolite powder, 140 to 170g of humic acid, 50 to 70g of radix dipsaci extract and 30 to 50g of radix polygonati officinalis extract. The water qualityimprovement agent disclosed by the invention can be used for accelerating the circulation of substances in a pond, inhibiting the raising of the pH (Potential of Hydrogen) value of a water body, changing a chemical progress of formation of harmful ammonia nitrogen and nitrite, reducing the generation of a water layer and substrate ammonia nitrogen, the nitrite and hydrogen sulfide, improving thechemical oxygen demand of pond bottom sludge, reducing dangers, caused by toxic and harmful chemical substances, on aquatic animals and prompting the growth of the aquatic animals; the water quality improvement agent has good social and economic benefits.

Description

technical field [0001] The invention relates to a water quality improver for aquaculture and a preparation method thereof, belonging to the technical field of aquaculture. Background technique [0002] The degree of intensification of modern aquaculture is getting higher and higher, and the high-density farming model will inevitably lead to the feeding of a large amount of high-protein feed. Therefore, a large amount of nitrogen-containing organic matter is input into the water body, and the pollution of aquatic animal excretion waste accelerates the aquaculture. The degree of deterioration of the water body, especially in the middle and late stages of aquaculture management, the aquaculture pond is in a high-temperature aquaculture season. In the case of insufficient dissolved oxygen, the above-mentioned nitrogen-containing organic matter and residual bait consume a large amount of dissolved oxygen in the water body, resulting in insufficient dissolved oxygen in the water bo...

Problems solved by technology

However, in the process of application, it was found that the existing water quality improvers are easy to apply and the effect is not good, it is difficult to effectively improve the water quality, and there are destructive raw materials in the improver, which will cause secondary pollution to the water body and affect the balance of microorganisms and algae in the water environment , will also affect the growth of farmed animals and cause adverse effects
