摘  要:
对4年生大木竹、椽竹、苦绿竹、橄榄竹的纤维长度、纤维宽度进行了显微观测与分析,结果表明,4个竹种的平均纤维长度为2.12~2.58mm,属略长至甚长纤维范畴,平均纤维宽度在11.69~12.75μm,各竹种的纤维长宽比为160~220,均适用于制纸原料。纤维形态在竹秆的不同部位存在着差别,在纵向上,竹材中部的纤维较长,基部次之,顶部居三,而纤维宽度为基部>中部>顶部;在径向上,纤维长度为内部>外部,而纤维宽度的差异不明显。

摘  要:
The fiber length & width were microscopic observed in 4-year-old culms of Bambusa wenchouensis,Bambusa textilis,Dendrocalamopsis basihirsuta & Acidosasa gigantea. Result shows the average fiber length of 4 bamboo species which are slightly long to very long,being 2. 12-2. 58 mm;the fiber width is 11. 69-12. 75 μm,the ratio of length and width are 160220,so 4 bamboo species are applied to paper materials. There are changes in different parts of bamboo culms. In vertical, the fiber length was middle > bottom > top,the width was bottom > middle > top. In radial,the fiber length is inside > outside,the width is not significantly different.
