What are the characteristics of microbial fertilizers

Microbial fertilizers play an important role in agricultural production, not only in improving the supply of soil nutrients, but also in promoting crop growth, disease resistance, stress resistance, increasing yield, improving quality and other aspects (taking microbial fungal agents as an example).

1, improve the supply of soil nutrients: microbial fertilizers mainly promote the dissolution and release of insoluble nutrients in the soil through various bacteria. At the same time, due to the release of a large number of inorganic organic acids by bacterial metabolism, it promotes the release and chelation of soil trace elements silicon, aluminum, iron, magnesium, molybdenum, effectively breaks the soil hardening, promotes the formation of particle structure, makes the soil fixed ineffective fertilizer into the effective fertilizer, and improves the soil nutrient supply, ventilation and loosening.

2. Promote crop growth: The use of microbial fertilizers promotes the production, regulation and development of plant growth regulators, that is, plant growth regulators. The use of microbial agents can promote the production of active substances such as gibberellin and auxin.

3. Enhance crop disease resistance and stress resistance: some bacteria in microbial fertilizer have the function of secreting antibiotics and a variety of active enzymes to inhibit or kill pathogenic fungi and bacteria; at the same time, a large number of field experiments have also proved that the application of microbial fertilizer can reduce the incidence of diseases and insect pests and improve the stress resistance of crops. It has a certain prevention and inhibition effect on cotton yellow blight, rice blast, wheat powdery mildew, stem rot, vegetable cataplexy, standing blight, green blight, etc. A large number of experiments have shown that diendi microbial agents can effectively inhibit the occurrence of certain types of nematode disease. At the same time, it also has obvious drought resistance, cold resistance, lodging resistance, salt and alkali resistance, improve the disease resistance of crops, and effectively prevent the occurrence of crop physiological diseases.

4. Improve yield and quality: The use of microbial fertilizer can improve the content of vitamin C, amino acids and sugar in agricultural products, effectively reduce the content of nitrate, and make the produced agricultural products delicious and beautiful, and sell at a good price. Crop yields can be increased by 20-30%.
