Pond sediment improving effervescing agent and preparation method and application thereof

Abstract

The invention discloses a pond sediment improving effervescing agent and a preparation method and application thereof. The pond sediment improving effervescing agent comprises a chemical sediment improving effervescing agent and a biological sediment improving effervescing agent. The chemical sediment improving effervescing agent comprises, by weight, 10-45 parts of potassium hydrogen persulfate,5-15 parts of calcium peroxide, 1-5 parts of ethylenediamine tetraacetic acid disodium salt, 1-20 parts of zeolite powder, 0-10 parts of activated carbon, 1-30 parts of baking soda, 1-20 parts of tartaric acid, 1-5 parts of talcum powder, and 1-3 parts of polyvinylpyrrolidone; the biological sediment improving effervescing agent comprises, by weight, 1-40 parts of humic acid, 1-20 parts of a microbial agent, 1-15 parts of kaolin, 1-30 parts of baking soda, 1-15 parts of tartaric acid, 1-3 parts of polyvinylpyrrolidone, and 1-5 parts of talcum powder. The pond sediment improving effervescing agent takes advantage of high acting speed and slow release to form, at the bed of a pond, a relatively long-term steady small environment, providing a beneficial environment for the reproduction of microbes.

Description

technical field [0001] The invention belongs to the technical field of a culture pond bottom quality improving agent, and more specifically relates to a pond bottom quality improving effervescent agent and a preparation method and application thereof. Background technique [0002] As the country pays more and more attention to environmental protection, although a large number of cages or fences in rivers, lakes, and reservoirs in our country have been dismantled or relocated, pond aquaculture, especially high-density intensive aquaculture, will continue to be used for a long time in the future. It will be the mainstream aquaculture model in our country. This model relies on high-density stocking of seedlings, feed feeding, chemical fertilizer application, and regular drug epidemic prevention to obtain high yields. [0003] However, the use of a large amount of feed, fertilizers and drugs hinders the material circulation and energy flow in the pond. In addition, the conversi...

Problems solved by technology

[0003] However, the use of a large amount of feed, fertilizers and drugs hinders the material circulation and energy flow in the pond. In addition, the conversion rate of N in the feed to the fish body is less than 40%, and a large number of untransformed substances exist in the water body and ponds in different forms. In the substrate; the frequent use of fertilizers and drugs causes the destruction of algae and fungi in the aquaculture water ecosystem, which leads to the inability of energy flow and material circulation in the pond water to be effectively carried out, and finally a large amount of nutrients are deposited, and the sludge in some ponds reaches more than 50cm, and even more than 80cm

However, the existing substrate improvement patents only start from certain aspects of substrate improvement and provide a technical route for pond substrate improvement, but they do not start from the perspective of constructing a benign pond substrate ecology. Therefore, they have not achieved Treat both the symptoms and root causes; in addition, the pond bottom has a lot of sludge, and if a lot of bottom improvement agents are put into it, it will be covered by sludge or soon covered by sludge, which greatly affects the improvement effect
