摘要
对巨尾桉不同无性系6年生人工林生长量及材性进行比较分析,结果表明:不同无性系间的胸径、树高、材积生长量差异显著或极显著,T35无性系生长量最大,其次为T13,T28;无性系T28胶合板材品质最好,其次为T35.不同无性系人工林胶合板材各材性指标存在不同程度的差异.8个无性系中T28是最适宜作定向培育胶合板原料林的无性系.
Comparative analyses on the growth and wood properties of 6-year-old Eucalyptu grandis ×Eucalyptus urophylla plantation with eight different clones were conducted. The results showed that there were extremely significant or simply significant differences among different clones in DBH, height and standing volume inside the Eucalyptus grandis × Eucalyptus urophylla plantation. Clone 335 had the largest successive growth, followed by Clone T13 and Clone T28. As to the wood quality as plywood manufacturing material, the best was Clone T28, followed by Clone 135. There were differences to certain degree in varied wood property indexes as plywood material among different clones. Comprehensively speaking, Clone T28 was the best among the 8 clones studied for directional cultivation for plywood manufacturing material.
