【摘要】 将悬铃木干材与枝材进行比较研究,为小径材、枝桠材等低等级的木材充分利用打下理论基础,对缓解日益紧张的木材供求矛盾,有着十分重要的理论和实践意义。通过对悬铃木枝、干材的纤维形态特征进行分析研究。结果发现,枝、干材纤维长度、直径、双壁厚、胞腔径和长宽比平均分别为1.441、1.380 mm,17.833、16.317μm,9.388、8.543μm,8.445、7.794μm和83.964、89.395,两者在0.05水平上经T-检验差异均显著。枝、干材纤维壁腔比和柔性系数分别为1.180、1.168和0.477、0.478,两者在0.05水平上经T-检验差异均不显著。更多还原

【Abstract】 In order to improve the rational bases for making fully use of the little diameter and branch wood,comparative study between the trunk and the branch of Platanus L.was conducted.It has very important theoretical and practical meaning for solving the problem of wood supply and demand.The fiber morphological characteristics of the trunk and the branch wood of Platanus L.were studied.The results show that the fiber length,diameter,double wall thickness,lumen-diameter and fiber length-width ratio of the branch and trunk are 1.441 mm and 1.380 mm,17.833 μm and 16.317 μm,9.388 μm and 8.543 μm,8.445 μm and 7.794 μm,as well as 83.964 and 89.395,the difference between them are all significant at 0.05 level through T-test.While the wall thickness-lumen ratio and the lumen-diameter ratio to diameter of fiber are 1.180 and 1.168,0.477 and 0.478,respectively.The difference between them are not significant at 0.05 level.更多还原
