example 1

[0022] Pour the mica rock into the ball milling tank, and add zirconia ball milling beads according to the mass ratio of the ball to material at 20:1. After ball milling and mixing for 8 hours, pass through a 500-mesh sieve to obtain mica powder. Take 50 parts of particles in turn according to the number of parts by weight. Urea, 10 parts of mica powder, 12 parts of polyallylamine, 150 parts of organic solvent, first pour polyallylamine and organic solvent into a beaker, stir, mix and dissolve with a stirrer at a speed of 500r / min for 40min, then add granular urea and Mica powder, under stirring state, pass carbon dioxide gas into the beaker at a rate of 40mL / min, continue to pass through 40min, filter to obtain pretreated granular urea; by weight parts, take 60 parts of chicken feathers, 50 parts of water , 5 parts of sucrose, poured into the fermenter, at a temperature of 40°C, a rotating speed of 500r / min, stirring and mixing at a constant temperature for 60 minutes, then ad...

[0024]In parts by weight, successively take 50 parts of granular urea, 10 parts of limestone, 12 parts of polyallylamine, and 150 parts of organic solvent, first pour polyallylamine and organic solvent into a beaker, and stir with a stirrer at a speed of 500r / min After mixing and dissolving for 40 minutes, add granular urea and limestone, and in a stirring state, pass carbon dioxide gas into the beaker at a rate of 40mL / min, continue to pass through for 40 minutes, and filter to obtain pretreated granular urea; Take 60 parts of chicken feathers, 50 parts of water, and 5 parts of sucrose in turn, and pour them into the fermenter. At a temperature of 40°C and a speed of 500 r / min, stir and mix at a constant temperature for 60 minutes, then add 6% of the mass of chicken feathers to the fermenter. Bacillus licheniformis was stirred and fermented at a constant temperature for 10 days to obtain a fermented material, and the obtained fermented material was transferred to an autoclave,...

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.

Description

technical field [0001] The invention discloses a preparation method of a slow-release anti-caking granular fertilizer, which belongs to the technical field of agricultural chemical fertilizer preparation. Background technique [0002] With the rapid development of economy and urbanization and the increase of population, people's demand for crops is increasing, so it is required that crops have a higher yield to meet people's growing needs. The addition of chemical fertilizers has attracted more and more attention as a way to increase crop yields. Chemical fertilizers are mostly made into granular fertilizers, which can reduce the hygroscopicity of fertilizers, reduce environmental pollution, and facilitate application. [0003] However, all fertilizers have agglomeration to varying degrees, which will affect their properties and performance. Agglomeration not only destroys the free-flowing state of the product, but also often needs to be crushed during use. Therefore, wheth...
