摘要
以四川不同地区两种丛生竹—慈竹和梁山慈竹为研究对象,通过测定纤维素和木质素含量以及纤维形态,对其变异规律进行研究。结果表明,同一地区不同竹种间纤维素和木质素含量差异显著,同一竹种不同地区间纤维素和木质素含量、纤维长度、宽度和纤维长宽比因地域差异而异,且与竹龄有关。从纸浆用竹和纤维原料综合考虑,竹海地区的慈竹(纤维素含量在45%左右,木质素含量低于28%)、梁山慈竹(纤维素含量在50%以上,木质素含量低于20%)比较适合竹浆造纸。
The changes of cellulose content and lignin content and fiber morphology were studied for Neosinocalamus affinis and Dendrocalamus farinosus with the typical thick-growing characteristics from the different regions in Sichuan province.The results showed that the cellulose content and lignin content were significantly different between the different species in the same region.The cellulose and lignin content,the length and width of fiber and their aspect ratio within the same specie of bamboo in the different regions were related to the different regions and the age of bamboos.Taking account of good fiber material of bamboo for paper making,N.affinis（cellulose content is about 45%,lignin content is below 28%） and D.farinosus（cellulose content is over 50%,lignin content is below 20%）from Zhuhai region are suitable for pulp making.
