间伐强度对水曲柳木材材质的影响

研究了不同间伐强度对水曲柳木材材质的影响，结果表明：间伐强度对水曲柳木材的纤维长度和胞壁率无显著影响；对生长轮宽度、晚材率、生长轮密度、木材硬度有显著影响；材质综合评定表明重度间伐的林分木材材质最优，轻度间伐林分材质次之，未间伐林分材质相对较差，可采取间伐的培育措施对水曲柳林木进行定向培育。

Effect of Thinning Intensity on Wood Quality of Fraxinus mandshurica/

This paper deals with the effect of thinning intensity on the wood properties of Fraxinus mandshurica . The main results showed that there are not significant effects for thinning intensity on fiber length and cell wall percentage of Fraxinus mandshurica . There are significant effects for thinning intensity on growth ring width, late wood percentage, growth ring density and hardness of Fraxinus mandshurica . The wood quality were evaluated comprehensively, the wood of severe thinning intensity tree might be the best, mild thinning intensity tree might be better, which could be used as fine silvicultural practice for oriented cultivation.
