摘　　要：将收集到的23个杨树优良无性系,在湖北省谷城县、夷陵区、监利县进行了对比造林试验,结果表明:(1)在谷城选出的长江杨、中嘉7号杨、375杨、鲁山杨4个优良无性系,适合超短轮伐期、中短轮伐期及短轮伐期定向培育栽培;(2)在夷陵试验区选出的鲁山杨、M81—18杨、351杨、375杨、中汉17杨5个无性系,适合超短轮伐期、中短轮伐期和短轮伐期栽培;(3)在监利县选出的长江杨、鲁山杨、303杨、中嘉8号、中汉578杨5个适合超短轮伐期栽培的无性系;中汉17、鲁山杨、375杨、M81-3、长江杨5个无性系适合中短轮伐期栽培;长江杨、鲁山杨、303杨、中汉17、375杨适合短轮伐期栽培;(4)3个试验区相比,无论是平均单株材积还是林分蓄积量,都是监利县最大,谷城次之,夷陵再次之。试验为湖北省杨树在不同区域、不同立地实现定向培育科学栽培提供了良种选择的依据。The multi-point comparative afforestation experiments of 23 collected poplar clones was carried out in the Gucheng County,Yiling District and Jianli County of Hubei Province.The results show：（1） In Gucheng County,4 clones including Zhongjia-7 Populus,Lushan Populus,375 Populus and Yangtze Populus were selected as the superior clones which are suitable for over-short term rotation operation,mid-short term rotation and short term rotation.（2） In Yiling District,5 clones including Lushan Populus,M81-18 Populus,351 Populus,375 Populus,Zhonghan-17 Populus were selected as the superior clones,and suitable for over-short term rotation operation,mid-short term rotation and short term rotation.（3） In Jianli County,5 clones including Yangtze Populus,Lushan Populus,303 Populus,Zhongjia-8 Populus,Zhonghan-578 Populus were selected for over-short term rotation,Zhonghan-17,Lushan Populus,375 Populus,M81-3 Populus and Yangtze Populus were selected for mid-short term rotation,Yangtze Populus,Lushan Populus,303 Populus,Zhonghan-17 and 375 Populus were selected for short term rotation.（4） Compared among three test area of the selected superior clones,whether in the average volume per plant,or stand stock volume,Jianli was the first,Gucheng was the second and Yiling was the last.So this study provides a fine seed selection basis for the poplar scientific and oriented cultivation in different regions and different site conditions in Hubei Province
