Example Embodiment

[0021] Example 1

[0022] Pour the mica rock into the ball mill tank, and add the zirconia ball mill beads according to the mass ratio of the balls to 20:1. After ball milling and mixing for 8 hours, pass through a 500 mesh sieve to obtain mica powder. Take 50 parts by weight in turn. 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 and mix with a stirrer at 500r / min for 40 minutes, then add granular urea and Mica powder, under agitation, inject carbon dioxide gas into the beaker at a rate of 40 mL / min, continue to infuse for 40 minutes, and filter to obtain pretreated granular urea; take 60 parts of chicken feathers and 50 parts of water in order by weight , 5 parts of sucrose, pour into the fermentation tank, at a temperature of 40 ℃, rotating speed 500r / min conditions, stirring and mixing at a constant temperature for 60 minutes, then add 6% chicken feather mass Bacillus l...

[0023] Example 2

[0024] In parts by weight, take 50 parts of granular urea, 10 parts of limestone, 12 parts of polyallylamine, and 150 parts of organic solvent. Pour the polyallylamine and organic solvent into the beaker and stir with a stirrer at 500r / min. After mixing and dissolving for 40 minutes, add granular urea and limestone. Under stirring, pass carbon dioxide gas into the beaker at a rate of 40 mL / min. After continuing for 40 minutes, filter to obtain pretreated granular urea; in parts by weight, 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 500r / min, stir and mix at a constant temperature for 60 minutes, and then add 6% of chicken feathers to the fermenter. Bacillus licheniformis was fermented at constant temperature for 10 days to obtain the fermented material, and the obtained fermented material was transferred to an autoclave, and sterilized at a temper...

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...
