对狼尾草的化学成分及纤维形态进行分析，结果表明：狼尾草秸秆中的综纤维素、聚戊糖、木质素、苯醇抽提物、灰分含量分别为71.83 %、19.60 %、23.48 %、2.84 %、4.84 %；叶、茎秆、节、枝梢、髓芯5个部分中，以叶中灰分含量最高，达到11.21 %；狼尾草秸秆纤维的长宽比为108，壁腔比为0.32；热磨后纤维中合格纤维的比例达到70.8 %；在一定工艺条件下压制狼尾草中密度纤维板试板，其静曲强度、弹性模量、内结合强度和吸水厚度膨胀率均达到国家标准GB/T 11718—1999的要求。研究表明狼尾草是制作中密度纤维板的一种潜在原料。

The analysis results of chemical composition of Chinese pennisetum showed that the contents of holocellulose, pentosan ,lignin, benzenealcohol extractives and ash were 71.83 %, 19.60 %,23.48 %, 2.84 % and 4.84 %respectively. The ash content of the leaf was the highest among the examined 5 parts of Chinese pennisetum, which was up to 11.21 %. The measurements of fiber morphology on Chinese pennisetum showed that the fiber aspect ratio is 108, and the ratio of cellwall thickness to cell diameter is 0.32. Of the thermalmechanical refined fibers, 70.8 % was the qualified long fibers and fiberbundles. The experimental panels of MDF from Chinese pennisetum were manufactured, and their physical and mechanical properties were evaluated. The modulus of rupture (MOR), modulus of elasticity (MOE), and internal bond (IB) of those panels met the requirements specified in China national standard GB/T 11718—1999. Analysis results showed that Chinese pennisetum was a potential feasible raw material for making medium density fiberboard.
