Prasanna等通过大田实验，研究蓝藻的定殖及其对土壤微生物和作物植

Prasanna et al. Conducted field experiments to study the colonization of cyanobacteria and their effects on soil microorganisms and crop plant parameters. The results showed that inoculation of nitrogen-fixing cyanobacteria under the conditions of applying total phosphorus and potassium and reducing chemical nitrogen fertilizer by 25% still promoted plant growth , Improve crop yield and significantly enhance soil microbial activity. It shows that nitrogen-fixing cyanobacteria not only secrete substances that promote plant growth and affect plant productivity and soil fertility, but also can serve as an organic input source in rice-wheat farming systems by providing nitrogen and carbon.

Prasanna et al. Studied the colonization of cyanobacteria and its effect on soil microorganisms and plant parameters of crops through field experiments. The results showed that the application of nitrogen fixing cyanobacteria under the conditions of total P, total K and 25% reduction of chemical nitrogen fertilizer still promoted plant growth, increased crop yield and significantly enhanced soil microbial activity. The results showed that nitrogen fixing cyanobacteria could not only promote the growth of plants, but also play an important role in the input of nitrogen and carbon in the rice wheat farming system.
