摘要
利用凤眼莲中的纤维素孔状结构,通过负载尿素、甲醛进行固化制备凤眼莲基缓释肥料。通过水浸泡法来考察凤眼莲用量、尿素浓度、固化剂用量等因素对其缓释性的影响,结果表明,凤眼莲用量为2.5 g、尿素浓度为40%、固化剂用量为0.1~0.12 g合成的凤眼莲基缓释肥料的缓释性最好。
The Eichhorniacrassipes, which was abundant of cellulose porous structure, was coated with carbamide to form an intergrated slow release fertilizer. The influence of factors such as the dosage of Eichhorniacrassipes, urea concentration and the amount of curing agent on the sustained-release was investigated by water immersion method. The results showed the optimum preparation conditions were thedosage of Eichhorniacrassipes was 2.5 g, the urea concentration was 40%, the amount of curing agent was 0.1～0.12 g.
