摘要
6个桉树无性系3年生林分生长量测定数据统计分析表明,无性系间树高和胸径生长量存在显著性差异,其中DH32-29、DH32-28的胸径分别为9.81 cm和9.76 cm、树高分别为13.50m和13.75 m,处于本试验无性系中较高水平。DH32-29、DH32-28单位面积蓄积量比其他无性系高55.5%~56.6%。因而,在类似港北区奇石乡兴中村的地理环境、气候及立地条件的地区种植桉树,选择DH32-29和DH32-28能获取较高的木材生长量。
The growth of 3 years old eucalyptus forest of 6 clones were measured respectively.Statistical data analysis shows that the height and diameter growth of these clones were significant different.The growth of DH32-29,DH32-28 were at the highest level in this test,which the diameter were 9.81cm and 9.76 cm,and the height were 13.50m and 13.75 m respectively,and the per unit area of stock was higher by 55.5%~56.6% than that of other clones.with the results that planting eucalyptus clones DH32-29 and DH32-28 at where geographical,climatic and site conditions were similar to Xingzhong village Qishi township Gangbei district can get high growth of wood.
