Abstract
The invention discloses a preparation method of a slow release type caking-preventing granular fertilizer, and belongs to technical field of agricultural fertilizer preparation. Poly (allyl amine) andan organic solvent are used under the effects of carbon dioxide gas, pretreatment is used for granular urea; chicken feather, water and sucrose are stirred and mixed, Baclicus lincheniformis is added, and after isothermal stirring and fermentation are carried out, disinfection, filtering and condensation are carried out in order to prepare feather hydrolysate; ultrasonic dispersion is carried outfor mica powder, phosphatide, mucoprotein and water in order to obtain dispersion liquid; feather hydrolysate and dispersion liquid are mixed in order to obtain film forming liquid; and finally, in afluidized bed, the film forming liquid is atomized and coated on the surface of the pretreated granular urea, drying is carried out, and the slow release type caking-preventing granular fertilizer isobtained. The slow release type caking-preventing granular fertilizer has excellent slow releasing effects and anti-caking performance.
