Problems solved by technology

Most of the existing pond bottom improvement agents combine biological methods with physical and chemical methods to achieve better results, but the disadvantages are: the added strains are not capable of degrading ammonia nitrogen, nitrite and sulfide at the bottom of the pond. Strong, poor effect of changing the bottom, and the rise of dissolved oxygen at the bottom of the pool is slow

Abstract

The invention relates to a pond substrate modifier, which is prepared from the following ingredients in parts by mass: 10 to 15 parts of zeolite powder, 30 to 55 parts of sodium humate, 10 to 20 parts of compound bacterium powder, 5 to 10 parts of compound enzyme, 10 to 20 parts of hydroxypropyl starch, 5 to 10 parts of protective agents and 5 to 15 parts of stabilizing agents, wherein the compound bacterial powder comprises bacillus subtilis bacterial powder, bacillus licheniformis bacterial powder, paracoccus denitrificans bacterial powder and thiobacillus denitrificans bacterial powder; and the pond substrate modifier has a double-layer structure. The invention further relates to a preparation method of the pond sediment modifier and application of the pond sediment modifier in the field of aquaculture. The pond sediment modifier can decompose organic matters at the bottom of a pond, reduce the content of ammonia nitrogen, nitrite and sulfide, and improve the transparency of a water body at the same time.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a pond bottom quality improver, a preparation method and an application thereof. Background technique [0002] With the rapid development of the aquaculture industry, the high-density and intensive farming model has become the mainstream farming model. The aquaculture output per unit of water body is getting higher and higher. The phenomenon of excessive input of feed into aquaculture ponds is very common, resulting in a large amount of residual bait, biological Organic matter such as debris and animal excrement is enriched at the bottom of the fish pond, and mixed with the bottom silt to form bottom mud. A certain thickness of bottom mud can play the role of fertilizer supply, fertilizer preservation, regulation and buffering of sudden changes in pond water quality. However, too thick bottom mud not only reduces the living space of aquatic animals, but also accum...
