摘　　要：为合理利用四川省宜宾市的竹材资源,发展竹材造纸工业,选用花吊丝竹、倬牡竹和梁山慈竹3种丛生竹作为研究对象,对其纤维形态、化学组成和制浆性能进行分析。结果表明,3种竹材的平均纤维长度在1.6 mm以上,长宽比均高于90;从化学成分上看,3种竹材的纤维素含量、半纤维素含量和苯醇抽提物含量无显著差异;除梁山慈竹外,另2种竹材的平均综纤维素含量均高于70%,达到造纸质量要求;倬牡竹的平均木质素含量相对较高,为23.08%;梁山慈竹的平均灰分含量为1.48%,显著高于另外2个竹种。综上,3种竹材均可用作造纸原料,从降低加工难度和加工成本的角度考虑,可选用木质素和灰分含量较低的花吊丝竹作为优质的制浆造纸原料。In order to make rational use of bamboo resources in Yibin city,Sichuan province,and develop the bamboo paper industry,three species of sympodial bamboo are selected,i.e.Dendrocalamus minor var.amoenus,D.mutatus and D.farinosus,to analyze fiber morphology,chemical composition and pulping properties.The results show that the average fiber length of the three species is more than 1.6 mm,and the length-width ratio is higher than 90.From the perspective of chemical composition,there is no significant difference in holocellulose content,hemicellulose content and benzene alcohol extract content among the three species.The holocellulose content is higher than 70%except for D.farinosus,which meets the requirements over the paper-making quality.The average lignin content of D.mutatus is relatively high,which is 23.08%.The average ash content of D.farinosus is 1.48%,significantly higher than that of the other two species.In summary,the timber of the three species can be used as the material for paper making.From the perspectives of reducing the difficulty and the cost of processing,D.minor var.amoenus,which has low lignin and low ash content,can be selected as the high-quality materials for pulping and papermaking.
