摘要
该文对宁夏新引进和原有的１４ 种杨树的生长及抗虫性进行了研究，发现欧洲山杨三倍体、截叶毛白杨等数种杨树，在一定的环境条件下，具有较好的相对抗虫性．并对其抗虫强度进行了排序．其抗虫性都优于新疆杨．
The growth and the relative insect\|resistance of 14 poplar in Ningxia are described. \%Populus tremula\% Qigas and \%Populus tomentosa\% Truncata and several other poplar species have greater resistant ability under certain environment. The order of resistance of these poplar species is obtained. They all have higher resistance than the \%Pupulus alba\% var.\%pyramidalis\% Lauche which is main species in Ningxia.
