| titleOfInvention | A kind of preparation method of water-retaining type ureaformaldehyde slow-release compound fertilizer |
| abstract | The present invention relates to a kind of preparation method of water-retaining type ureaformaldehyde slow-release compound fertilizer, including step：(1) urea-formaldehyde condensation product solution processed；(2) starch graft copolymer processed；(3) azophoska is mixed to be placed in comminutor and is heated to 60~85 DEG C, add urea-formaldehyde condensation product solution, starch graft copolymer carries out mixing granulation into comminutor, make urea-formaldehyde condensation product, starch graft copolymer mixes the surface for being coated on granulated fertilizer, the water-retaining type ureaformaldehyde slow-release compound fertilizer of the present invention realizes slow release of the nutrient in soil, on the one hand utilization rate of fertilizer is greatly improved, improve utilization rate of fertilizer, on the other hand, the water-holding slow-release layer formed after urea-formaldehyde condensation product and starch graft copolymer crosslinking can significantly improve water holding capacity, free formaldehyde can be adsorbed again, improve soil water stable aggregate content, increase soil fertility, improve the rate of release of the plain nutrition of soil quality control N P and K. |
