摘要：以雷州 1号桉 (Eucalyptus leizhou No. 1)、柠檬桉 (E. citriodora)和尾叶桉 (E. urophylla)为研究对象 ,测量其不同年龄立木的轴向生长应变以及生材材性指标参数。研究表明 ,采伐、树木高度对生长应变测量的影响可以忽略 ;树种种间、种内不同树龄的轴向生长应变差异显著 ,但变异规律复杂 ,有待进一步研究。生长应变与树木胸径显著相关 ,而与木材基本密度和生材密度无关。
The trees from plantation Eucalyptus leizhou No1, E. citriodora and E. urophylla, were selected to study. The measurements of longitudinal growth strains of standing trees were conducted for three Eucalyptuses in different age, and the measurement of some parameters of green wood property also was done for them. The analysis showed: the effects of fell and height of trees on growth strains were negligible; the variance of growth strains among three species and in different age within a species was significant, but the variance trend was different. There was significant correlation between growth strains and breast height diameter of trees, but no significant correlation between growth strains and wood basic density.
