| Abstract: | One humic acid/amylum/polyacrylic acid resin, applied to slow release fertilizer, was prepared from humic acid, amylum, acrylic acid by the method of copolymerization and cross-linking. The optimal mass ratio of humic acid, amylum, acrylic acid and N,N-methylenebisacrylamide was 8：20：72, and the max water absorption amount was 659 g/g for deionized water and 425 g/g for urea was 60-70 day, meeting the technological standards tap water. The results showed that slow-release time of of GB/T23348-2009. |
