摘　　要：对云南甜竹化学成分和纤维形态的分析结果表明:云南甜竹含灰分1.12%、木质素27.08%、综纤维素72.96%、多戊糖15.51%、冷水抽出物7.50%、热水抽出物9.35%、1%NaOH抽出物21.60%、乙醚抽出物0.35%、苯醇抽出物3.46%;云南甜竹纤维长度为2.65 mm、宽度为15.26μm、长宽比为174,细胞腔径为14.88μm、壁厚为2.80μm、壁腔比为0.38。从化学成分和纤维形态来看,云南甜竹属优良的纸浆生产原料。The chemical composition and fiber morphology of Dendrocalamus brandisii was studied in this paper. The results show that D. brandisii contains 1.12 % of ash, 27.08 % of lignin, 72.96 % of holocellulose, 15.51% of pentosane, 7.05 % of cold-water extractive, 9.35 % of hot-water extractive, 21.60 % of 1% NaOH extractive, 0.35 % of diethyl ether extractive, 3.46 % of benzene-alcohol extractive;And the fiber length is 2.65 mm, fiber width is 15.26 μm, length/width ratio is 174, the fiber lumen diameter is 14.88 μm, fiber wall thickness is 2.80 μm, thickness/diameter ratio is 0.38, respectively. On the basis of chemical composition and fiber morphology, D. brandisii is one of the good materials for pulping.
