洞庭湖区欧美黑杨化学组成及纤维形态的分析

Analysis and Research on Chemical Composition and Fiber Morphology of Europe Black Poplar in Dongting Lake Area

对产自洞庭湖区欧美黑杨不同部位的化学组成及纤维长度分布的差异性进行分析研究,结果表明:主干材纤维素含量48.55%、木素含量22.95%,与枝、桠材比较,纤维素含量分别高0.75与1.75个百分点,木素含量低1.85与2.65个百分点;平均纤维长度主干材明显大于枝材和桠材,长宽比值主干材略大于枝材和桠材。

Chemical composition in difference part and the distribution difference of fiber length morphology Europe black poplaser in Dongting Lake Area were analyzed. The results showed that the cellulose of main bodywood is 48.55%, the lignin content is 22.95%, compared with branch and fork material, the cellulose content is higher 0.75% and 1.75%, the lignin contend is lower 1.85% and 2.65% respectively. The average fiber length of main bodywood is obviously longer than brand and fork material, the length-width ratio of main bodywood is higher little than brand and fork material.
