摘要
研究了不同抚育间伐强度对紫椴木材材质的影响 ,结果表明 :抚育间伐对紫椴木材纤维长度、胞壁率的影响不显著 ,对生长轮宽度和生长轮密度、木材硬度和小拉伸强度有显著影响。材质综合评定表明 ,轻度间伐的林分材质最优 。
The paper discusses the effect of thinning intensity on wood properties of Tilia amurensis . The main results show that the effects of thinning intensity are not significant on fiber length and cell wall percentage of Tilia amurensis ; while the effects of thinning intensity are significant on growth ring width, growth ring density, small tensile strength and hardness of Tilia amurensis . The evaluation for wood qualities shows that the wood quality of mild thinning intensity tree is the best, which can be used as fine silvicultural practice for oriented cultivation.
