摘要
采用系列固定标准地测定方法,对广西选育出来推广的尾巨桉Eucalyptus urophylla×E.grandis无性系DH32-28和DH32-29,巨尾桉E.grandis×E.urophylla无性系GL-9和引种自广东省的尾叶桉E.urophylla无性系U6进行造林生长对比及经营效益测算。结果表明,无性系DH32-28,GL-9和DH32-29比U6在单位面积蓄积量、木材收入及经营利润上具明显优势。优先推广前3个无性系,将是桉树林发展的更好选择。
With the fixed spot test method, the growth and economic evaluation of Eucalyptus urophylla x E. grandis clones DH32-28 and DH32-29, E. grandis x E. urophylla clone GL-9 in Guangxi Province were compared with that of E. urophylla clone U-6 which was introduced from Guangdong Province. The results showed that DH32-28, GL-9 and DH32-29 had obvious growth advantages on per unit area yield of stock, the wood income and profit. These three clones would be the best choice for Eucalyptus plantation. [ Ch, 7 tab. 12 ref. ]
