Effect test
Embodiment 1
[0026] This example provides a treatment method for the water quality of "red water" in wintering ponds in the north (a water body in which a single dinoflagellate algae forms an advantage), so as to ensure the safety of overwintering.
[0027] (1) Test time and place:
[0028] On October 20, 2019, the test was carried out in two open-air ponds in Shuangyao Village, Yangchengzhuang Town, Jinghai District, Tianjin. The areas of the two ponds were 200 mu (1#) and 120 mu (2#), respectively, and the average water depth was 1.8 Meter.
[0029] (2) Test pond conditions:
[0030] Both ponds are polyculture fish ponds, and the shrimps have been harvested. Before the test started, the water quality of the two ponds was dominated by dinoflagellates and a small amount of zooplankton.
[0031] (3) Test method:
[0032] 1# is the control pond, the water quality is fresher, and the color is not as deep as the 2# pond. 2# pond is a test pond, the water color is redder;
[0033] The tes...
Embodiment 2
[0039] This embodiment provides a treatment method for the "brown water" water quality of wintering ponds in the north (not the water body dominated by single algae, but the water quality dominated by euglena and dinoflagellates), so as to ensure the safety of wintering.
[0040] (1) Test time and place:
[0041] On October 21, 2019, the test was carried out in two open-air ponds in Jianxin Fishing Ground, Dasi Town, Tianjin. The two ponds had an area of 40 mu (1#) and 30 mu (2#) respectively, and the average water depth was 2 meters.
[0042] (2) Test pond conditions:
[0043] The two ponds are intensive fish ponds. Before the test started, the water quality was dominated by euglena and dinoflagellates, and they showed anorexia and did not go on stage.
[0044] (3) Test method:
[0045] 1# pond is the control pond, 2# pond is the test pond;
[0046] The test started (October 21st) in the 2# pond, 30kg of strong chlorine was used to splash half of the pond in the limelig...

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...
