The main ingredients of compound microbial agents include a variety of microbial species, as follows:
Actinomycetes nocardi: has antibacterial and stress resistance, and can inhibit the growth of pathogens.
Bacillus subtilis: widely used in soil improvement and plant disease control.
Bacillus jelly (i.e. silicate bacteria): can decompose silicates and release nutrients that can be absorbed by plants.
Bacillus megaterium phosphate-solubilizing (phosphorus bacteria): can decompose phosphorus and improve the effectiveness of soil phosphorus.
Bacillus cereus: has antibacterial and stress resistance.
Bacillus thuringiensis: has insecticidal effects on certain pests.
Photosynthetic bacteria (such as Rhodopseudomonas palustris): can carry out photosynthesis, produce beneficial substances, and promote plant growth.
Filamentous bacteria: participate in the formation of soil structure and enhance soil fertility.
Alcohol yeast: Participates in the fermentation process of organic matter and promotes the release of nutrients.
