4种相思树种人工林木材纤维形态的研究

摘要

Fiber morphology of four Acacia species wood from plantation were determined and analysed com⁃parative.The results indicated that Acacia melanoxy and Acacia Implexa wood had short-sized fiber,Acacia crassicapa and Acacia mangiun wood had medium-sized fiber.Moreover,the ratio of fiber wall thickness to diameter for four Acacia species wood were all less than 1.The order of Acacia wood from plantation as a raw material for papermaking merits was A.melanoxy,A.Mangiun,A.Implexa and A.crassicapa.There was ex⁃tremely significant difference or significant difference in fiber length between different Acacia species wood. In addition,there weren’t significant differences in ratio of fiber wall thickness to diameter between A.mela⁃noxy and A.implexa wood from plantation while there were extremely significant difference between others different Acacia species wood.There were extremely significant differences in every feature of fiber morpholo⁃gy between A.crassicapa and A.melanoxy,A.mangiun and A.melanoxy wood from plantation.%对4个相思树种人工林木材纤维形态特征进行测定和比较分析，结果表明：黑木相思和灰木相思的木材纤维属于短纤维，厚荚相思和马占相思的木材纤维属于中等纤维，4种相思木材壁腔比均小于1。相思树种人工林木材作为造纸原料的优劣顺序为：厚荚相思、马占相思、黑木相思和灰木相思。4个相思树种人工林木材纤维长度差异均达显著或极显著水平；黑木相思与灰木相思人工林木材纤维壁腔比差异不显著，其余相思树种差异极显著；厚荚相思与灰木相思、马占相思与灰木相思木材人工林木材纤维各形态特征均差异极显著。
