<正>利用混合及单一杀虫利，采用注干、涂干等方法对松突圆蚧进行林间药效试验，同时对几种方法处理后的松突圆蚧种群消长情况进行跟踪调查。结果表明：注干和涂干法处理时，混合药剂的最佳组合均为rIO%杀扑磷乳油（V（乐扑磷乳油）：V（水）=1：5）+40%毒死蜱乳油（V（毒死蜱乳油）：V（水）=1：5）+40%氧乐果乳油（V（氧乐果乳油）：V（水）=1：2.5）混合。采用注干法和涂干法的防治效果分别达98%和81%，虫口减退较明显。而喷雾法处理的虫口波动较大。

Vegetative Storage Protein (VSP) was the main form of nitrogen storage and played an important roles in the cycle of nitrogen in many woody plants. The result of research on the distribution of VSP in trees and the mechanism of accumulation and degradation of the VSP in woody plants were reviewed in the article. The internal and exterior factors that affected the metabolization of VSP were discussed strongly in this paper. Meanwhile, the perspective of studying physiological functions of VSP was prospected.
