摘　　要：为指导宣纸的生产和使用,以青檀树皮为研究对象,对其化学组成、纤维形态和细胞壁结构进行研究。结果表明:青檀树皮的综纤维素含量为61.43%,木质素含量为9.03%,灰分含量为5.07%,从其化学组成来看,檀皮的木质素含量较低,容易制浆,但制浆得率比较低,檀皮中碳酸钙含量高,有利于增强宣纸的润墨性;檀皮纤维的细胞壁厚,微纤丝多,其间的空隙也多,使宣纸的吸墨性很好;檀皮纤维的平均长度为2.95mm,均整性较好,平均宽度为10.99μm,长宽比为268,较一般针叶材纤维大。In order to guide production and use of xuan paper, chemical compositions, fiber morphology properties, and structure of cell wall in Pteroceltis tatarinowii bark were tatarinowii bark The results showed that the contents of holocellulose, lignin and ash in P, tatarinwii bark were 61. 43%, 9.03%, 5.07%, respectively. Lower lignin content makes pulp easy, but pulp yield was relatively low. And higher CaCO2 content is favor of ink absorption. The cell wall was thick and consisted of many micro-fibrils, and micro-eapacity made the xuan paper have good ink absorption. Average fiber length was 2.95 mm, and distribution of length was even Average fiber width was 10. 99 μm. The ratio of fiber length to width was 266, which was bigger than general coniferous woods.
