| 摘 要： | 以羧甲基葡甘聚糖和聚乙烯醇为原料,通过溶液共混、交联制备了新型肥料包膜.利用红外光谱表征了交联包膜的结构,并测试了包膜的吸水率和膜中尿素的释放性能.结果表明:包膜内聚乙烯醇、羧甲基葡甘聚糖和尿素之间产生了较强的相互作用,包膜内尿素具有一定的缓释性.

| Abstract: | A new type of fertilizer coating was prepared by solution methods with carboxylmethyl glucomannan and poly vinyl alcohol.The film was characterized by FTIR,percent water absorption and the release character of urea in the coating.The results indicated that there is some strong interaction among the poly(vinyl alcohol),glucomannan carboxylmethyl and urea in the coating,the urea in the coating has slow-release character on a certain degree. |

| Keywords: | poly vinyl alcohol carboxylmethyl glucomannan fertilizer coating compatibility slow-release Performance |
