Abstract

The invention discloses a preparation method of a microbial bottom modification agent, and the microbial bottom modification agent is prepare by the steps of material selection, material preparation, crushing, mixing, granulating, drying and cooling in the air and the like. The microbial bottom modification agent produced can effectively control water body PH in 7.50-8.50, improve water body transparency to 6.3-4.1 cm, increase DO (dissolved oxygen) content to 28.95%-37.50%, reduce the content of COD (chemical oxygen demand), PO4-P and nitrite in water body respectively to 39.41%-69.28%, 30.28%-69.28% and 24.39%-56.06%, effectively inhibit the overgrowth of algae in the water body, and improve eutrophication status of aquaculture water bodies.

Description

[0001] technical field [0002] The invention belongs to the technical field of water body bottom improvement, and in particular relates to a preparation method of a microbial bottom improvement agent. [0003] Background technique [0004] Penaeus vannamei has the advantages of fast growth, strong adaptability, tender meat, high rate of processed meat, long out-of-water survival time and strong disease resistance. In recent years, with the popularization and popularization of intensive and high-density farming methods, the shrimp farming environment has deteriorated day by day, and the pH value, chemical oxygen demand, total inorganic nitrogen, phosphate and other indicators of the farming water have seriously exceeded the standard, and the shrimp has been in a state of stress for a long time , its physiological function is reduced, and even poisoning or activation of infectious pathogens occurs, which leads to the outbreak of various infectious diseases in high-density fa...
