Northern overwintering pond water quality treatment method

Abstract

The invention relates to a northern overwintering pond water quality treatment method which comprises the following steps: uniformly splashing a microbial agent into a northern aquaculture pond in autumn within the splashing range of the water surface of the whole pond; when the water body is a water body with advantages formed by single algae, namely the color of the water body is yellow (chrysophyta), red (dinoflagellate) or yellow green (diatom and dinoflagellate), bacillus coagulans is selected as the microbial agent, the use amount of the microbial agent is that one kilogram of the microbial agentis used for every3-4 mu of water surface, and the microbial agent is mixed with water to be uniformly splashed; when a water body is not a dominant water body formed by single algae (most algae are Dinoflagellates such as dinoflagellates, chrysophyta and euglena), a disinfectant is splashed to 1 / 4-1 / 3 of the water surface of the pond, a microbial agent rhodopseudomonas palustris is mixed with water to be evenly splashed after 10-15 days, and 0.5-1 L of the microbial agent is used on every 1 mu of water surface with water depth smaller than 2 meters. The method for treating the water quality of the northern overwintering pond through the microbial agent is high in pertinence, free of metal residues and free of water quality pollution.

Description

technical field [0001] The invention belongs to the technical field of ecological breeding, and in particular relates to a water quality treatment method for overwintering ponds in northern China. Background technique [0002] Breeding ponds in the north often have overwintering ponds, that is, the adult fish raised in the current year will produce fish in the spring of the second year. Before wintering, the water quality must be treated so that it is not fat or thin, and there must be no dinoflagellates, golden algae and other algae. Generally, the water quality should be adjusted in autumn. [0003] Due to the different pond conditions, the dominant algae formed are different, and the methods of water quality regulation are also different. General treatment methods include: killing insects, using copper sulfate to kill algae, using halogen-containing disinfectants (such as trichloroisocyanuric acid, chlorine dioxide, etc.) for disinfection, and using N fertilizer (such as...

Problems solved by technology

This treatment method is not friendly to the environment, that is, there are copper and iron residues and the N and P content in the aquaculture water are too high, polluting the water quality; second, it is not targeted, that is, there is no targeted adjustment for different algae, and the effect after abnormal water quality occurs very poor
