摘　　要：对三年生华北落叶松幼苗四种不同处理下的铜、锌元素含量、酶活性及苗木生长状况进行试验研究 ,结果表明 :铜元素可明显提高多酚氧化酶活性 ;锌元素有利于细胞膜的稳定 ,对增强华北落叶松抗性有重要作用 ;铜。To the 3-old years LPR seedling, we have studied the content of Copper(Cu) and Zinc(Zn), ferment activity and its seedlings' growing condition under four different treatment. The results show that (1) Cu can improve Poly-phenol oxidase\ activity obviously; (2) Zn is of benefit to the stable ability of biomembrane, helping to improve the resistant ability of LPR; (3) The content of Cu and Zn have effect on the growing of LPR's seedlings.
