摘要
对毛竹不同海拔类型的竹材纤维形态、化学成份等分析研究表明:不同海拔间竹林纤维长度、宽度与长度比在一定范围内存在一定差异;胸径与纤维长度、宽度呈负相关(r=-0.362 3与-0.390 7);不同年龄的竹材纤维长度、宽度亦存在一定规律性变化。随年龄增加,木素含量也随之增大;抽提物中热水、1%NaOH、苯醇(苯和乙醇的混合液)随之减小。竹林养分元素含量分析表明,随海拔增高, N、 P、K、Ca等元素也有一定规律性变化。
The studies on the morphology of fiber and chemical component bamboo wood of Phyllostachys heterocycle cv.Pubescensof different altitude has showed: There are certain difference between the lenth and the ratio of width and lenth of the fiber of different altitude, The relativity between diameter and fiber lenth and with are regative, Meanwhile, the fiber lenth and width of different age also varies regularly with the age increasing,the content of ligin increases,but hot water. 1%NaOH. the mixture of phene and alcohol. in the isolates decrease. The analysis of the content of nutritious elements in the bamboo forest also showed that the elements of N. P K. Ca vary regularly with the altitude increasing.
