Types and Effects of Agricultural Microbial Bacteria

- Oct 25, 2017 -

Bacillus subtilis: increase crop resistance, nitrogen fixation.

Bacillus licheniformis: resistance to disease, kill harmful bacteria.

Bacillus amyloliquefaciens: secrete antimicrobial substances, produce antagonism, nutrition and space competition, induce host resistance and promote plant growth

Bacillus megaterium: Phosphorus (phosphorus bacteria), has a good effect of degradation of organic phosphorus in soil.

Bacillus thuringiensis: potassium, the release of soluble phosphorus and potassium and calcium, sulfur, magnesium, iron, zinc, molybdenum, manganese and other trace elements.

Bacillus sp.: Promoting root, sterilizing and degrading heavy metals.

Bacillus sp.: Soluble phosphorus, potassium release and nitrogen fixation function, secrete a variety of enzymes, enhance the resistance of crops to some diseases.

Jingyang Streptomyces: the ability to enhance soil fertility and stimulate crop growth.

Mycorrhizal fungi: to expand the root absorption surface, increase the absorption of the original roots of elements (especially phosphorus) absorption capacity.

Brown nitrogen fixation bacteria: fixed nitrogen in the air, increase production.

Round brown azotobacter: nitrogen fixation, improve crop yield.

Actinomycetes: antagonize the role of pathogens to prevent the growth of bacteria, secrete cytokinins to promote crop growth.

Photosynthetic bacteria: synthetic carbohydrates, amino acids, vitamins, nitrogen compounds, antiviral substances and physiologically active substances, is the fertile soil and promote the growth of the main force of animal and plant.

Lactic acid bacteria group: has a strong bactericidal ability, can effectively inhibit the activities of harmful microbes and organic decomposition of the rapid decomposition of decomposition in the normal can not easily decompose lignin and cellulose, and organic matter fermentation decomposition. Lactobacillus also inhibited the proliferation of pathogens produced by continuous cropping obstacles.

Yeast flora: synthesis of active substances that promote root growth and cell division, and the matrix (food) needed to promote the proliferation of other effective microbes provide important support

Bacillus coagulans: can reduce the environment of ammonia, hydrogen sulfide and other harmful gases. Improve the content of amino acids in fruits.

Aspergillus oryzae: the organic matter in the straw to become the nutrients needed for plant growth, improve soil organic matter, improve soil structure. Decomposition of protein, cellulose, hemicellulose, lignin and so on, and thermophilic, heat-resistant bacteria, fungi, yeast strains and related decomposition enzyme complex, the degradation ability, and can achieve warming, deodorization, eliminate pests and diseases , Weed seeds and improve nutrient effects

Aspergillus niger: cleavage of macromolecular organic matter and insoluble inorganic, easy to crop absorption and utilization, improve soil structure, enhance soil fertility, improve crop yield.

Trichoderma viride is one of the highest strains of cellulase produced, the resulting cellulase degradation of crops, the effect is very good, but also a resource-rich antagonistic microorganisms, with the protection and treatment of dual effects , Can effectively prevent soil-borne diseases.

Trichoderma harzianum is used to prevent plant diseases caused by pathogens such as Pythium, Rhizoctonia solani, Fusarium, Rhizopus oryzae,

Pseudomonas syringae: a variety of nematodes have control effectiveness, is the prevention and treatment of root-knot nematode the most promising biocontrol agents.

Beauveria bassiana: kill pests in natural conditions through body wall contact infection

Metarhizium anisopliae: a class of insecticidal fungi that can be parasitic to a variety of pests, through the body surface invasion into the pest body, in the pests continue to multiply through the consumption of nutrients, mechanical penetration, produce toxins, and continue to spread in pests So that the pests are dead.

EM: A single strain of Bacteroides, Lactobacillus, Bacillus (Bacillus licheniformis, Bacillus subtilis, Bacillus sphaericus, Bacillus thuringiensis, etc.), photosynthetic bacteria, yeasts, actinomycetes, Acetobacteria and so on. Technology alone expansion, fermentation, spray drying from the efficient combination of microbial strains.
