摘　　要：为选择适宜阿尔乡沙地生长的杨树品种,采用随机区组试验,在阿尔乡沙地对彰武小钻杨、银中杨、群众杨和黑林1号杨进行造林对比试验,连续12年监测不同杨树品种胸径、树高的生长量。结果表明,胸径生长量从大到小依次为银中杨、群众杨、彰武小钻杨、黑林1号杨,分别为20.69、19.98、19.34、15.71 cm,树高生长量从大到小依次为银中杨、彰武小钻杨、群众杨、黑林1号杨,分别为15.52、13.39、13.29、9.01 m。银中杨、群众杨、彰武小钻杨胸径和树高生长量与黑林1号杨之间差异显著。In order to select poplar species suitable for growth in Aerxiang sandy land,a randomized block test was used to conduct afforestation comparative test of Populus×Xiaozhuanica cv.Zhangwu,Populus alba×P.berolinensis,Populus simonii×Populus pyramidalis+Salix matsudana cv.‘Poplaris’and(Populus simonii×P.nigra)×P.15ACL‘Heilin1’in Aerxiang sandy land.The growth of poplar varieties at breast height and height for 12 consecutive years were monitored.Result shows that the DBH in descending order of Populus alba×P.berolinensis,Zhongzhong poplar,Populus×Xiaozhuanica cv.Zhangwu,and(Populus simonii×P.nigra)×P.15ACL‘Heilin1’,respectively,is 20.69,19.98,19.34,15.71 cm,respectively and the tree height growth from large to small They are Populus alba×P.berolinensis,Populus×Xiaozhuanica W.Y.Hsu et L.cv.Zhangwu,Populus simonii×(Populus pyramidalis+Salix matsudana)cv.‘Poplaris’and(Populus simonii×P.nigra)×P.15ACL‘Heilin1’,respectively,with a size of 15.52,13.39,13.29&9.01 m.There are significant differences in the diameter at breast height and the growth of tree height between Populus alba×P.berolinensis,Populus simonii×(Populus pyramidalis+Salix matsudana)cv.‘Poplaris’and Populus×Xiaozhuanica cv.Zhangwu and(Populus simonii×P.nigra)×P.15ACL‘Heilin1’.
