摘　　要：为了选择适合沙地生长的优良杨树品种,采用随机区组试验,在章古台沙地对群众杨、银中杨、黑林1号杨和彰武小钻杨进行造林对比试验,连续14年监测胸径、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、彰武小钻杨、群众杨、黑林1号杨,分别为18.0、16.6、16.5、15.9 cm;树高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15.4、12.5、12.3、11.2 m。银中杨胸径、树高生长量与其它品种之间差异性显著,黑林1号杨生长量最小。在发展潜力和经济效益方面,银中杨既可作为用材林树种也可作为绿化树种,可在相似沙地大力发展;黑林1号杨不适宜在章古台种植。The purpose of this study was to select excellent poplar varieties suitable for sandy land planting.A randomized block experiment was used to compare the afforestation effects of Populus simonii×(P.pyramidalis+Salix matsudana),Populus alba×P.berolinensis,(P.simonii×P.nigra)×P.euramericana cv.15ACL and Populus xiaozhuanica cv.‘Zhangwu’in the sandy land of Zhanggutai.The DBH and tree height growth were monitored for 14 consecutive years.DBH increment of tested species arranged from large to small was:Populus alba×P.berolinensis,Populus xiaozhuanica cv.‘Zhangwu’,Populus simonii×(P.pyramidalis+Salix matsudana)and(P.simonii×P.nigra)×P.euramericana cv.15ACL,which was 18.0 cm、16.6cm、16.5 cm、15.9 cm respectively.Height increasement of tested species arranged from large to small was:Populus alba×P.berolinensis,Populus simonii×(P.pyramidalis+Salix matsudana),Populus xiaozhuanica cv.‘Zhangwu’and(P.simonii×P.nigra)×P.euramericana cv.15ACL,which was 15.4 m,12.5 m,12.3 m,11.2 m respectively.There were significant differences in DBH and tree height growth between P.alba×P.berolinensis and the others.The increasement of(P.simonii×P.nigra)×P.euramericana cv.15ACL was the smallest.Considering the development potential and economic benefits,P.alba×P.berolinensis can be used as either timber tree species or greening tree species,and can be vigorously developed in similar sandy land.(P.simonii×P.nigra)×P.euramericana cv.15ACL is not suitable for planting in Zhanggutai.
