摘　　要：对硬头黄（Bambusa rigida）、巨竹（Gigantochloa levis（Bles））Merr）、马甲竹Bambusa tulda Roxb）和梁山慈竹（Dendrocalamus farinosus）的化学成分和纤维形态进行了分析研究。结果表明，4种竹子的综纤维素含量相对较高，木素和聚戊糖含量与阔叶材相当，抽出物含量较高。从纤维形态看，马甲竹和巨竹的纤维长度及长宽比最大，硬头黄在1．0～3．0mm范围内的纤维含量最高。通过两种方法解离纤维原料，L＆W纤维测定仪的测定结果表明：硝酸一氯酸钾法适合于硬头黄原料的细胞解离，冰醋酸一过氧化氢法用于巨竹、马甲竹、梁山慈竹的细胞解离更好。The analysis and study on the chemical composition and fiber morphology of fotar kinds of bamboo including Bambusa rigida, Gigantocbloa levis （Bles） Merr, Bambusa tulda Roxb and Dendrocalamus farinosus were made.THe results showed that the content of holocellulose in these four kinds of bamboo was comparatively high, lignin and pentosan contents were similar to that of hardwood and the contents of extractives were relatively high. Through the fiber property analysis, Bambusa tulda Roxb and Gigantochloa levis （Bles） Merr had higher fiber length and the ratio of length/width. Bambusa rigida had the highest content of fiber that range from 1.0 to 3.0mm. Two methods were used in the separation treatment of fiber materials. It was showed that the fiber ofBambusa rigida treated by the method of HNO3-KCIO3 was longer through the test result of L＆W fiber tester. However, the fiber of Gigantochloa levis （Bles） Merr, Bambusa tulda Roxb and Dendrocalamusfarinosus treated by the method of HAc-H202 was longer.
