【摘要】 本文对内蒙古河套地区产新疆杨的木材宏、微观构造，纤维形态进行了观测，并对新疆杨木材的ｐＨ值，物理力学性质进行了研究，结果表明：新疆杨生长迅速，树干通直，其木材纹理直，心边材区分不明显，质软，结构中而均匀，侵填体丰富，天然耐久性好，木纤维中韧性纤维丰富；纤维平均长１２３２．５μｍ，长宽比５２．４０，柔性系数０．６４，壁腔比０．２８，纤维形态在杨属木材中居上；木材呈弱酸性；木材密度小，干缩性中等；材性在杨属木材中属较好者，木材强度属中等等级，新疆杨木材质量品质系数属高品质系数木材类，适于作为纸浆及人造板生产原料等工业性开发。更多还原

【Abstract】 The structure and fiber shape of populus boueana lanche in the Hetao area of Inner Mongolia is observed,and its pH value and physico mechanical properties are measured.The result show that the populus shows little acidity,middle strength,light density,straight grain,better wood properies.Its fratures are as follows:the average length of fiber is 1 232.5 μm,the proportion of length to width is 52.40,the flexibility ratio is 0.64,the proportion of wall to cavity 0.28.Populus boueana Lanche is good raw material for pulp and artificial board.更多还原
