摘要:对广西10种野生竹材：青皮竹、沙罗单竹、撑篙竹、大绿竹、壮绿竹、清甜竹、花吊丝竹、油竹、耳垂竹、甲竹的纤维形态及结构进行了研究。结果表明，广西10种野生竹材纤维整体直且细长，花吊丝竹的纤维长度（3.19 mm）最长；10种野生竹材的纤维密度分布在1.20~1.45 g/cm³之间，其中青皮竹纤维的密度最小，为1.21 g/cm³；10种野生竹材纤维的微纤丝角分布在8°~11°之间。

Abstract:The fiber morphology and structure of ten species of wild bamboo in Guangxi （Bambusa textilis， Schizostachyum funghomii， Bambusa pervariabilis， Bambusa grandis， Bambusa Validus， Dendrocalamus sapidus， Dendrocalamus minor var. amoenus， Bambusa surrecta， Schizostachyum auriculatum， Bambusa remotiflora） were studied. The results showed that the fibers of the ten species of wild bamboo were straight and slender， of which the longest fiber was the Dendrocalamus minor var. amoenus （3.19 mm）. The fiber density of ten species of wild bamboo ranged from 1.20 to 1.45 g/cm³. Among them， the density of Bambusa textilis fiber （1.21 g/cm³） was the smallest. The microfibril angles of ten wild bamboo fibers were between 8° and 11°.
