摘要:
 研究酸枣人工林木材纤维形态和基本密度随树龄的变化规律。结果表明,酸枣人工林木纤维长度、长宽比随树龄的增大而增大,15 a时达到相对稳定状态,木纤维长度和长宽比分别为1 170 μm和82.1,木纤维宽度变化范围为14.8~21.2 μm,7 a时木纤维宽度达到最大为21.2 μm。酸枣人工林木材基本密度随树龄的增长而增大,10 a左右达到相对稳定的状态,基本密度为0.497 g/cm3。从木纤维长度分布特征的径向变异分析得出,随着树龄的增大短纤维所占的比例越来越小,长纤维所占的比例越来越大,15 a时达到相对稳定状态。
Abstract:
 The variation laws of fiber morphology and basic density with tree age for Choerospondias axillaris wood from plantation were researched and revealed.The results showed that the fiber length and ratio of the length to width increased with tree age,and reached a stable state at the 15th year.Wood fiber length and the ratio of length to width were 1 170 μm and 82.1,respectively.The variation scope of wood fiber width was 14.8-21.2 μm.Wood fiber width was up to maximum (21.2 μm) at the 7th year.The basic density increased with tree age,and relatively stable with basic density of 0.497 g/cm3 at the 10th year.The analysis of radial variations for distribution characteristics of wood fiber length indicated that the proportion of short fiber decreased,while the long fiber increased with tree age,and stable at the 15th year.
