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.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizer production, in particular to a granulation method of microbial fertilizer. Background technique [0002] Fertilizers are an important guarantee for increasing grain production. In today's world, chemical fertilizers contribute 50% to increasing grain production. China is the country that uses the most fertilizers in the world, but at present, the total amount of chemical fertilizers in my country is insufficient, the structure of fertilization and fertilizers is unreasonable, the distribution of fertilizers is unbalanced, and waste is serious. The utilization rate of chemical fertilizers is low, and they are not absorbed by crops after application. Fertilizers enter the environment in large quantities, causing pollution to the environment. It not only destroys land resources, but also poses a threat to human health. Therefore, it is of great significance to improve fertilizer use effi...
