凹叶厚朴人工林材性的研究

A Study on the Timber Property of the Magnolia officinalis Plantation

对不同林分密度管理的凹叶厚朴人工林木材物理力学性质的测定结果表明 :不同密度管理方式对凹叶厚朴木材纤维特性、化学组成、基本密度和干缩性等物理化学性质的影响不显著 ,但对木材力学性质有显著影响 ,以密组的木材品质指数较高 .根据凹叶厚朴的生长特征、木材材性的工艺性能 ,凹叶厚朴适合以建筑材、家具用材和装饰用材林为培育目标 ,因此 ,经营密度均不宜过高 ,在本试验条件下以中组 (保留 1 5 0 5株 /hm2 )为宜 .

By studying the timber physical and strength properties of the Magnolia officinalis of different planting density control,the results showed that the influences of different planting density control on the physical and chemical properties such as fibre properties,chemical composition,basic density and shrinkage properties were not remarkable,but those on the timber strength properties were remarkable and the wood indices of high density group were the highest.According to the timber technology performance and the biological properties of Magnolia officinalis,it was cultivater suitably for timber forest of building,furniture and decoration woods.The forest density of Magnolia officinalis was suitable for middle density group(1 505 bodies of/hm2)under its experimental conditions and not too high.
