| 摘 要： | 以山海关杨为对照，在唐山地区进行不同杨树无性系对比试验。经过7a试验，结果表明：108杨生长表现突出，107杨次之，白杨表现最差。7a生108杨林木平均胸径、平均树高和平均单株材积分别为20．3cm、15．57m和0．1500m^3，超过山海关杨1．18倍、1．30倍和4．15倍；多重比较表明，108杨和107杨各生长指标与对照差异达极显著，同时该无性系还具有造林成活率高、抗性强等优良特性，可以在唐山地区推广应用。

| Abstract: | The comparative experiment of different clones of Populus was carried out in Tangshan, taking the local dominant species of Populus canadensis cv. ＇ Shanhaiguanensis＇ as the control. Based on the seven - year growth analysis of the comparative experiment, the results showed that： Populus × curamericana ＇Guarienta＇ performed well both in adaptability and growth characteristics, Populus × euramericana ＇Neva＇ was the second and the white poplar was the worst. The mean diameter, mean height and mean individual volume in Populus × euramericana ＇ Guarienta＇ were 20.3 cm, 15.57 m and 0. 1500 m^3 respectively,which were 1.18 times,1.30 times and 4.15 times larger than those of the control. Furthermore, the two best performance clones can be cultivated easily, show high resistance to poplar pest, have evident growth advantage and are best for afforestation and application in Tangshan. |
