Background technique

Bio-organic fertilizer refers to a type of fertilizer that combines the effects of microbial fertilizers and organic fertilizers, which is composed of specific functional microorganisms and organic materials that are mainly derived from animal and plant residues and have been harmlessly treated and decomposed. The beneficial microorganisms in the bio-organic fertilizer enter the soil and form a symbiotic relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic role in the group. The beneficial bacteria grow and reproduce A large number of metabolites are produced during the process, which promotes the decomposition and transformation of organic matter, and can directly or indirectly provide crops with a variety of nutrients and stimulating substances to promote and regulate crop growth.

The production process of bio-organic fertilizer generally starts with fermentation.
