Abstract

The invention relates to a method for controlling soil and fixing nitrogen by using blue algae, the method is characterized in that the blue algae are dried and crushed and then applied to the soil, the soil is loosened, and the use amount of fertilizers can be reduced.

Description

technical field [0001] The invention relates to a method for using cyanobacteria to control soil and fix nitrogen. Background technique [0002] cyanobacteria Also known as blue-green algae (blue-green algae), it is a class of long evolutionary history, negative Gram staining, no flagella, containing chlorophyll a, but does not contain chloroplasts (different from eukaryotic algae), capable of oxygen production Large photosynthetic unicellular prokaryotes. Some cyanobacteria cause eutrophic seawater "green tide" and lake "bloom" after being polluted by nitrogen, phosphorus and other elements, which bring serious harm to fishery and aquaculture. The usual treatment is to landfill or incinerate the blue-green algae after salvage. Because cyanobacteria contain toxins such as cyclic peptides and alkaloids, the way of landfilling may cause pollution to the water body; the method of burning will cause pollution to the atmosphere. [0003] At present, there are also methods of ...
