| 摘 要： | 对不同树龄和不同部位日本落叶松木材的化学组成、糖类组成进行了研究。结果表明,不同树龄日本落叶松木材的化学组成存在一定的差异：随着树龄的增大,总碳水化合物含量逐渐降低;冷水抽出物、热水抽出物和1％NaOH抽出物的含量增加;灰分含量逐渐降低;聚糖组成中葡萄糖和木糖含量降低,半乳糖含量增加。从化学组成分析看,12年生和15年生日本落叶松的木材比20a以上树龄的更适合用作造纸原料。与兴安落叶松相比,日本落叶松的水抽出物与1％NaOH抽出物含量较低,聚糖中葡萄糖含量较多而半乳糖含量较少;从化学组成来说,日本落叶松木材是一种优于兴安落叶松木材的造纸原料。 |

| Abstract: | The chemical compositions and saccharide of Larix kaempferi in different tree age and different vertical location within a stem were investigated. In a result,the chemical compositions of Larix kaempferi in different tree age had certain difference. With the growing of Larix kaempferi tree,the total carbohydrate decreases,water extraction and 1%NaOH extraction increase,glucose and xylose decrease,galactose increases. Taking chemical compositions into account,12-years and 15-years Larix kaempferi had an advantage over those aged more than 20 years in papermaking.As compared with L.gmelinii,its water extraction,1%NaOH extraction and galactose were less,however,glucose was more.So Larix kaempferi was better than L.gmelinii in papermaking. |
| Keywords: | Larix kaempferi timber papermaking chemical compositions |
