通过对早、晚型种子包衣肥的pH值、包衣均匀度、包衣脱落率、初期溶出率、微分溶出率、养分累积释放曲线的测定,以及对衣膜结构、包衣水稻种子与未包衣的对照种子表面结构扫描电镜观察,研究了种子包衣肥的理化特性.结果表明:早、晚稻型种子包衣肥的pH值为5～6、包衣均匀度>96%、包衣脱落率

Physical and chemical characteristics of seed-coating fertilizers were studied by means of determining the pH values,coating uniformity rates,coating off rates,nutrient initial-release ratios,nutrient micro-release ratios,nutrient accumulation-release curves of early and late rice seed-coating fertilizers,and observing the membrane structures of seed-coating fertilizers and the surface structures of the coated and uncoated rice seeds by SEM. Results showed that the pH values of early and late seed-coating fertilizers were 56,coating uniformity ...
