Description

Technical Field

[0001] The invention relates to the technical field of fertilizers, in particular to an active microbial fertilizer and a preparation method thereof. Background Art

[0002] Microbial fertilizers are a type of living microbial products that give crops a specific fertilizer effect through the life activities of microorganisms and their products. They have low production costs, good effects, and do not pollute the environment. After application, they not only increase production, but also improve the quality of agricultural products and reduce the amount of chemical fertilizers. In agricultural production, microbial fertilizers are gradually used to replace chemical fertilizers. At present, microbial fertilizers can be divided into two categories according to their composition: microbial agents and compound microbial fertilizers. At present, compound microbial fertilizers contain not only effective microorganisms, but also some nutrients; however, due to technical limitations, there may be unreasonable strain ratios, and most of them cannot form dominant bacterial communities in the soil, and cannot achieve the technical effects of nitrogen fixation, phosphorus solubilization, and potassium solubilization.
