Bio organic fertilizer is a kind of fertilizer with the function of both microbial fertilizer and organic fertilizer. It is composed of specific functional microorganisms and organic matter mainly from animal and plant residues. After harmless treatment, it is fermented and processed by fertilizer granulator.
The specific functional microorganisms of bio organic fertilizer are as follows:
1. Nitrogen fixing bacteria can grow and propagate in large numbers by using organic matter in soil as carbon source and nitrogen dioxide in air as nitrogen;
2. It can decompose phosphate solubilizing bacteria and potassium solubilizing bacteria, and consolidate the phosphorus and potassium elements in soil or soil parent material.
3. Beneficial bacteria that can antagonize the growth and reproduction of soil borne pathogens.
Bio organic fertilizer generally contains a certain amount of functional microorganisms. When applied to the soil, the soil temperature reaches 25 ~ 35 ℃, the pH value is 5.5 ~ 8.5, and the soil water holding capacity is 50 ~ 70%, showing a geometric progression. Every kind of beneficial bacteria is the source of fertilizer, and it is difficult to grow and reproduce. It is equivalent to that the fertilizer production plants move to the ground, and constantly produce nitrogen, phosphorus, potassium and trace elements to promote the absorption and utilization of crops. Using the rotary drum granulator to add these bacteria into the organic fertilizer, so as to improve the yield and quality of crops, improve the soil, and reduce the occurrence of diseases and pests.
