| 摘 要： | 试验在其它桑园管理措施一致的前提下,改变其N、P2O5、K2O肥的施用比例,并对桑叶产、质量进行了调查。结果是N∶P2O5∶K2O=10∶5∶5的施肥比例,能显著提高生长芽生长量,极显著提高春叶产量;适当提高种茧4龄起蚕结茧率和虫蛹统一生命率。显著提高全茧量及茧层量。极显著提高卵质成绩及下代孵化率。

| Abstract: | The experiment was conducted that changing the N, P2O5, K2O ratio of fertilizer application, and the survey of mulberry leaf yield and quality. The results were N：P2O5：K2O=10：5：5 ratio of fertilizer application could significantly enhance the growth of shoots, significantly enhance leaf production in spring crop; appropriate improve cocooning rate of 4th instar, larva-pupae survival rate, significantly enhance cocoon weight and cocoon shell weight, significantly improve egg quality score and hatching rate of the next generation. |
