在分析研究红皮云杉人工林主要材性的基础上、较为系统地研究了人工红皮云杉纸浆材主要材性指 标与林龄、林分密度和立地条件的关系。研究结果表明：红皮云杉木材纤维素含量较高（６７．１５％～ ８０．１０％），纤 维细长，长宽比达７０％以上，且人工林与天然林材性差异不大。是造纸的优良原料。红皮云杉人工林主要材性指 标与林龄密切相关。而受林分密度和立地条件的影响较小。２０年生基本密度为 ０．３１７９ ｇ／ｃｍ３。纤维长 １．９９ｍｍ。 长宽比 ７１．７８，综纤维素含量７１．５４％。 １％ ＮａＯＨ抽出物为 ２０．１０％，总的趋势是其材性值随林龄增大而增加。红 皮云杉人工林主要材性指标在２０年生后即达到造纸要求。
Based on the analysis of main materials of Picea koraiensis plantation, the relationship between the main timber quality index and stand age, stand density and site conditions was systematically studied. The results showed that the content of Cellulose in Picea koraiensis was higher (67.15% -80.10%), the fiber length was slender, the aspect ratio was more than 70%, and the difference between the plantation and the natural forest was not significant. Paper is an excellent raw material. The main wood quality indicators of Picea koraiensis plantation are closely related to the age. But less affected by the stand density and site conditions. The basic annual density of 20 years is 0.3179 g / cm3. Fiber length 1.99mm. Aspect ratio 71.78, holocellulose content 71.54%. 1% NaOH extract was 20.10%, the general trend is that its material value increases with age. The main material properties of the red spruce plantation reached the papermaking requirements after 20 years.
