| 摘 要： | 通过室外样地调查和室内木材材性分析及硫酸盐制浆实验,研究了不同立地条件下长白落叶松工业纤维林的生长过程、木材纤维特性、化学组成、物理性质和制浆特点,指出了立地条件对林分生长、木材纤维含量、纤维长度、纤维长宽比、得浆率、纸浆物理强度的影响。结果表明,长白落叶松工业纤维林生长最佳的立地条件是山地下部Ⅰ、Ⅱ地位级。立地条件对木材材性和纸浆特性有直接影响。在研究的林分密度和立地条件范围内,立地条件越差,木材纤维含量越少,纤维长度越短,纤维长宽比越小,1%NaOH提取物越多。而且这种现象有随林龄增长而加重的趋势。但立地条件对得浆率和纸浆的物理强度影响不明显。综合林分生长和木材材性,长白落叶松工业纤维林的培育最好在山地下部Ⅰ地位级和Ⅱ地位级的立地条件下进行。表4参17。

| Abstract: | Plot sampling was conducted in the second cultivation areas of Larix olgensis in Heilongjiang Province, China. By analyzing plot investigation data, wood properties, and kraft pulps of 840 plots and 248 sample trees in industrial plantations of L. olgensis on different sites, we examined the growth process of L. olgensis industrial plantation with suitable structure, the wood fiber feature, chemical composi- tion, physical performance and pulp characteristics. It is suggested that site conditions have major effects on plantation growth, fiber con- tains, fiber length, rate between fiber length and fiber width, pulping rate and pulp physics intensity. The best site for L. olgensis industrial plantation growth is site class I and site class II, which are on lower locations. Site condition has an obvious influence on the wood charac- teristics. Within the range of site conditions and stand densities studied, the worse the site condition, the less the fiber contains, the shorter the fiber length, and the more the 1 % NaOH extraction. This kind of relationship becomes more obvious as stand age increases. However, the influence of site condition on pulping rate and pulp physics intensity is not obvious. The result provides theoretical base for cultivation of industrial fiber plantation of L. olgensis. |
