摘要:
通过21个桉树无性系造林对比试验研究,结果表明:试验中第一、二年桉树无性系幼林树高、胸径和材积生长在区组和无性系间的差异均达极显著。1年生时桉树无性系树高和材积表现最好的3个无性系是DH3326、DH201-2和G9,而胸径是DH3326、G9和DH201-2;2年生时桉树无性系树高表现最好的3个无性系是DH3326、DH3229和DH201-2,而胸径和材积是DH3326、DH3229和EC53。

Abstract:
Studied on the contrast afforestation experiment of 21 Eucalyptus clones the same site conditions.The results showed that there were significant discrepancies between the 21 Eucalyptus clones in DBH,height or volume respectively.In first year,the best clones were DH3326、DH201-2 and G9 in height or volume, howere, the DH3326、G9 and DH201-2 were better than the others in aspect of DHB.In second year,the best clones were DH3326、DH3229 and DH201-2 in height,but the DH3326、DH3229 and EC53 were super than the others in DHB and volume.
