| 摘 要： | 目的]探讨大叶栎人工林木材纤维形态的变异规律。方法]以大叶栎23年生人工林为材料,测定纤维的长度、宽度、腔径、双壁厚、长宽比、壁腔比,分析大叶栎木材纤维沿树干高度和随年轮的变异规律。结果]大叶栎人工林木材纤维长度、宽度、腔径、双壁厚和长宽比、壁腔比分别变化在1098.2～1224.6、24.22～26.38、15.95～17.02、8.26～9.36μm和43.37～51.12、0.521～0.555,平均值分别为1156.2、25.43、16.56、8.87μm和46.01、0.540。纤维长度、长宽比和壁腔比随树干高度增加呈下降趋势,随年轮的增加呈增加趋势。结论]大叶栎人工林木材纤维能满足纤维工业原料的要求,是一种较好的纸浆工业用材。
