| 摘 要： | 对8种杨树，包括采自南方的4种（响叶杨、I-214、鲁克斯和哈佛）和采自北方的4种（中金2号、中金10号、中绥5号和28-77号），进行了木材化学成分的分析。结果表明:水分、灰分和苯醇抽出物的含量较低，8种杨树的平均值分别为9.69%，0.68%和1.74%。纤维素和综纤维素的含量较高，平均值分别为48.76%和77.19%。木质素和戊聚糖的平均含量分别为21.54%和21.72%。按制浆造纸原料要求的标准来比较，这些杨木纤维素和综纤维素的含量高，抽出物和木质素的含量低，当属优质原料。采自北方的4种比南方的4种更好。

| Abstract: | An analysis of wood chemical composition was carried out for eight poplars, of which four (Populus adenopoda, P.eura cv. `I-214, P.deltoides cv.`Lux and P.deltoides cv. `Havard) sampled from south of China and four (P.deltoides ev. `Zs-5, p. popu-eura cv. `28-77, P.deltoides cv. `Zj- 2 and P.popularis cv. `Zj-10)from north of China. The results showed that the averaged contents of water, ash and benzene-alcohol extractives were low, 9.69%, 0.68% and 1.74% respectively. The contents of cellulose and holocellulose were high, 48.76% and 77.19% respectively; and lignin and pentosans were 21.54% and 21.72% respectively. With respect to the criteria required for pulpwood, these poplars were all of superior pulping material. The four northern species, however, were better than the sourthern four. |
