摘　　要：引种对比试验结果表明:窄冠黑杨新品种在天津地区适应能力较强,生长表现良好,未发现异常灾害;但各品种间生长差异显著,窄冠黑杨055号综合表现突出,优于对照中林46杨和其他品种;窄冠黑杨11号与中林46杨大体相当;窄冠黑杨078号和窄冠黑白杨生长表现最差;窄冠黑杨1号和2号表现中等,有待于继续试验观察。An experiment was conducted to introduce fast growing tree species with narrow crown in Tianjin region. Result shows that the black poplar with narrow crown has strong adaptability and grows well, and no abnormal calamity occurs. While a significant difference in tree growth was found between different varieties. Black peplar-055 with narrow crown exhibits outstanding growth performance, which is superior to Poplar Zhonglin-46 and other varieties. The growth status of black peplar-ll with narrow crown is equivalent to Poplar Zhong[in-Zl6, and black peplar-76 and black-white poplar with narrow crown grow poorly. The grow perforrnances of black peplar-1 and black peplar-2 with narrow crown are medium, which need further investigation.
