杜仲幼树短截效应和防护效益的研究

Effect of Cut-back on the Eucommia Young Trees and Protection Benifits

本文通过采取不同的短截方式来研究杜仲幼树的短截效应；并应用常规方法，测定杜仲幼树的防护效益。数据分析结果认为，１／３短截方式具有较好的“复壮效应”，能提高杜仲幼树生长量；

The effects of cut-back of the Eucommia was studied by various methods of cut-back and the protection benifits of Eucommia were determined by general method. Data analysis showed that it will give more farouable “rejuvenation effect”to cut 1/3 of the stem and branches of the Eucommia, the growth of the young trees was increased evidently, while the protection benifits of Eucommia young trees were higher.
