Description
Technical field
The present invention relates to a kind of preparation method of microbial organic fertilizer, belong to soil improvement composite fertilizer field.
Background technology
Hilly upland topsoil short texture easily loses, and severe water and soil erosion causes that soil moisture and nutrient run off in a large number, leadCause soil fertility degeneration and fertilization effect and reduce, the raising of restriction hillside fields productivity. Most is to change with microorganismGood soil, but the adaptability of the contained large multipair natural environment of bacterial classification of the bio-feritlizer that circulated is on the market poor, to soilThe DeGrain of improvement, the water content that need to increase soil improves the vitality of microorganism. But existing microorganism hasMachine fertilizer is not obvious to the improved effect of soil, is therefore badly in need of the side of a kind of novel water-loss reducer of preparation and the composite fertilizer of microorganismMethod.
Summary of the invention
The object of this invention is to provide that a kind of can to contribute to the indissoluble substance dissolves in soil be the battalion that can be absorbed by plantsSupport the preparation method of the microbial organic fertilizer of material, be particularly suitable for improving the productivity of hilly upland.
For realizing above object, the preparation method of a kind of microbial organic fertilizer of the present invention, concrete steps are:
