[目的]研究施肥对尾巨桉木材纤维与木材基本密度的影响.[方法]以18a生3种不同施肥处理的尾巨桉无性系木材为研究材料,研究木材纤维特征、木材基本密度及变异情况.[结果]3种施肥处理的木材基本密度、纤维长度、纤维长宽比、壁厚、壁腔比在树干径向方向由髓心向外都有逐渐增大的变化趋势,而纤维腔径在树干径向方向由髓心向外有逐渐减小的变化趋势,纤维宽度变化在3种施肥处理间不一致.3种施肥处理间只有纤维壁腔比差异达到显著水平,施肥量中间处理的纤维壁腔比值显著高于其余2个处理.[结论]不同施肥处理对木材纤维特性除纤维壁腔比之外差异不显著.
Effects of Fertilizer on Wood Fibre and Basic Density in E.urophylla × E.grandis
[ Objective ] Effects of Fertilizer on Wood Fibre and Basic Density in E. urophyUa x E. grandis were studied. [ Method ] The fibre characteristics and basic density and their variations were investigated in 18-year-old E. uropkylla x E. grandis with three fertilizer treatments. [ Result ]The basic density, fibre length, ratio of fibre length to width, wall thickness of fibre and ratio of wall thickness of fibre cell to the cavity diameter (T/D) increased from pith to bark in each of the three treatments while the cavity diameter of fibre decreased. Variation of fibre width from pith outwards was inconsistent between treatments. The ratio T/D was influenced significantly by the fertilizer treatments, with higher ratio in the mid-fertilizer treatment. [ Conclusion]Three treatments on the wood fibre charaters except the ratio T/D had no significant differences.
