摘  要:
在广西国有东门林场开展50个杂交桉无性系对比试验,通过对3.8年生参试无性系的保存率和生长表现观测,结果表明:至3.8a时,各杂交桉无性系的保存率都在75%以上;它们在树高、胸径、单株材积以及蓄积量上的差异,达极显著水平(p<0.001)。其中,生长较好的10个无性系为7、8、47、6、12、15、18、4、23、29号,它们的年平均蓄积生长量保持在30m3.hm-2。这些杂交桉无性系生长快、适应性强,有较大的生产潜力,适宜推广。

摘  要:
A field trial to examine fifty hybrid Eucalyptus clones established in Dongmen Forest Farm was assessed for growth at age 3.8 years.Survival rates and growth performance of all trees were recorded in detail.The results showed that all clones had over 75% survival.However,there were significant differences(P<0.001) among clones for tree height,diameter at breast height,individual tree volume and volume yield.The best ten clones,which included clones 7,8,47,6,12,15,18,4,23 and 29,kept their average annual cumulative growth at about 30 m3·hm-2.These top 10 hybrid Eucalyptus clones exhibit excellent quality in fast growing and environmental adaptation,which imply they could be widely planted in Guangxi.
