Abstract
The invention discloses a granulation method of a microbial fertilizer. The method comprises: carrying out solid fermentation on an organic material containing microbial bacteria to obtain a bacterial fertilizer, and carrying out molding granulation on the bacterial fertilizer to obtain bacterial fertilizer particles; carrying out surface mechanical activation treatment on the bacterial fertilizer particles; respectively preparing modified starch with the particle size of 0.01-5 microns and aerated concrete powder with the particle size of 50-200 microns, mixing the modified starch with the aerated concrete powder, adding a dispersing solvent, and stirring to obtain coating slurry; and carrying out coating treatment on the bacterial fertilizer particles by using the coating slurry, and drying to obtain the microbial fertilizer. In the granulation process of the biological bacterial fertilizer, the surfaces of fertilizer particles are firstly activated and then coated with the coating film prepared from the aerated concrete powder and the modified starch, so that fertilizer efficiency components are fully fixed and cannot be directly and completely collapsed, dissolved and lost when meeting water, and stable dissolution and emission of the fertilizer efficiency can be always kept by the microporous structure; therefore, the slow-release effect is achieved, the environmental tolerance of the biological bacterial fertilizer is improved, and the long-term stability of the fertilizer efficiency is ensured.
