Technical Field
The invention relates to the technical field of blue algae resource utilization, in particular to a method for controlling and recycling blue algae.
Background
Blue-green algae, also known as blue-green algae, is a large unicellular prokaryotic organism with a long history of evolution, gram-negative, nonflagellate, chlorophyll-a-containing but not chloroplast (distinct from eukaryotic algae) and capable of aerobic photosynthesis.
Its development has led to the entire earth's atmosphere going from an anaerobic state to an aerobic state, thus gestating the evolution and development of all aerobic organisms. More than 120 kinds of cyanobacteria have nitrogen fixation capability so far, and particularly, aquatic fern azolla imbricata which is symbiotic with anabaena imbricata is a good green manure. However, some cyanobacteria cause eutrophic seawater "red tide" and lake "water bloom" after being polluted by elements such as nitrogen and phosphorus, and bring serious harm to fishery and aquaculture.
In order to prevent the occurrence of red tide and water bloom, zeolite powder and bacillus algicidal (Bacillus laterosporus) need to be splashed in the blue algae enrichment place, and after the zeolite powder and the bacillus algicidal eliminate the harm of the blue algae, the zeolite powder and the bacillus algicidal can be factors influencing the fishery and the breeding industry again, so further improvement is needed.
