| 摘 要： | 采用SAS、SPSS等软件分析了4种造林密度(2 500、3 300、4 400、6 600株/hm2)对杂种落叶松的生长、木材密度、纤维长度、纤维宽度及纤维素含量的影响。结果表明:造林密度对杂种落叶松的生长影响非常显著,对纤维长度、宽度影响显著(P<0.05),对木材密度和纤维素含量影响不显著。11年生杂种落叶松的平均纤维长度为2.52 mm,平均宽度为40.56μm,长宽比平均值为64.88,纤维素的平均含量为50.41%。

| Abstract: | The growth, wood density, fiber length, width and cellulose content of different planting densities to Hybrid larch were studied by using SAS, SPSS software. The result showed that the effect of planting density on growth, fiber length and width was distinct （ P 〈 0. 05 ）, on wood density and cellulose content was not significant, The average fiber length were 2. 52mm, fiber width were 40. 56, aspect ratio were 64.88, cellulose content were 50. 41%, these meet the demands of fiber industrial raw materials. |
