采用SAS、SPSS等软件分析了4种造林密度(2500、3300、4400、6600: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2.52mm,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%。
採用SAS、SPSS等軟件分析瞭4種造林密度(2500、3300、4400、6600:株/hm2)對雜種落葉鬆的生長、木材密度、纖維長度、纖維寬度及纖維素含量的影響。結果錶明:造林密度對雜種落葉鬆的生長影響非常顯著,對纖維長度、寬度影響顯著(P〈0.05),對木材密度和纖維素含量影響不顯著。11年生雜種落葉鬆的平均纖維長度為2.52mm,平均寬度為40.56μm,長寬比平均值為64.88,纖維素的平均含量為50.41%。

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.
