A cyanobacteria inhibitor made by compound phosphorus-fixing bacteria

Abstract

The invention discloses application of a water body used blue-green algae inhibitor prepared from compound type phosphorus-fixing bacterium. The product is a compound preparation and restrains propagation of blue-green algae in the water body under the combined action of inclusions; blue-green algae are suitable for growing in the water body environment at a high temperature and in high hyperphosphate still water. The product, the compound phosphorus-fixing bacterium preparation, is prepared through matching and mixing an active coagulant, the compound phosphorus-fixing bacterium subjected to intensified cultivation in a hyperphosphate environment and various mineral salts facilitating propagation of various useful algae, can quickly consume and fix nutrient phosphor salt in the water body, blocks the photosynthesis of blue-green algae, and facilitates growth of useful algae, thereby excellently restraining propagation of blue-green algae. The preparation includes the following components in weight percentage: 15-40% of the coagulant, 25-50% of the phosphorus-fixing bacterium and 30-60% of mineral salts; the components subjected to scientific compatibility and used in sunny days at the usage amount of 50-100 g / mu. m excellently restrain the blue-green algae in water body, and the product is convenient to use, non-toxic and non-harmful, and excellent in stability.

Description

technical field [0001] The invention relates to a cyanobacteria inhibitor for fresh water bodies. More specifically, it relates to a cyanobacteria inhibitor in freshwater waters and its application. Background technique [0002] At present, with the rapid development of the economy and the improvement of people's living standards, the eutrophication of water bodies in various regions of the country is becoming more and more serious. Cyanobacterial blooms are one of the more common eutrophication phenomena, which mainly occur in freshwater bodies such as lakes, rivers, reservoirs and aquaculture ponds. Once the blue-green algae break out in the water body, a layer of blue-green and fishy-smelling foam will be formed on the water surface, causing deterioration of water quality and odor of the water body, affecting the ecological balance and landscape of the water body. In aquaculture ponds, due to problems such as backward breeding technology and poor management of the breed...

At this stage, in response to the occurrence of cyanobacteria, the measures commonly adopted in many areas are to use heavy metal compounds such as copper sulfate and chelated copper to kill, but the effect is often not obvious, and the use of heavy metal compounds will cause serious pollution of heavy metal ions in the water. Exceeding the standard, destroying the ecological environment of the water body, and causing very serious physical damage to aquaculture animals, which in turn affects the economic benefits of the majority of farmers, causing huge economic losses and serious social problems
