Granulation method of microbial fertilizer
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.
本发明公开了一种微生物菌肥的造粒方法，步骤包括：将含有微生物菌的有机物料进行固体发酵，得到菌肥，再将菌肥经成型造粒得到菌肥颗粒；对所述菌肥颗粒进行表面机械活化处理；分别制取粒径为0.01‑5μm的改性淀粉和粒径为50‑200μm的加气混凝土粉，将改性淀粉与加气混凝土粉混合后，加入分散溶剂搅拌得到包覆浆；采用包覆浆对菌肥颗粒进行包覆处理，干燥后即得微生物菌肥。该生物菌肥在造粒过程中，先对肥料颗粒表面进行活化处理，再包覆有由加气混凝土粉和改性淀粉制成的包覆膜，使得肥效成份被充分固定，遇水不会直接全部坍缩溶解流失，且微孔结构始终能保持肥效的稳定溶解散发，从而起到了缓释作用，提升了生物菌肥的环境耐受性，保证其肥效的长期稳定性。
