不同海拔天山云杉木材纤维长度和宽度的研究

Length and Width of Fiber of Tianshan Spruce at Several Altitudes

对新疆主要针叶树种天山云杉木材进行了不同海拔高度上纤维长宽和纤维宽度的显微测试和分析。结果表明 :海拔高度对纤维长宽和宽度有影响 ,以高海拔 (2 750 m处 )纤维平均长度较长 ,晚材纤维长宽比较大 ,其值分别为 2 732 μm和 12 2 .

The length and width of fiber of Spruce from several altitudes of Xinjiang Tianshan were microscopical tested and analysed.The result showed that the length and width of fiber was affected by altitudes;The average length of spruce fiber at 2 750 m above sea level was the longest and the ratio of length and breadth of late wood was larger,the numerical value was 2 733 μm and 122.4.
