摘要

通过对银杏木材微纤丝角的径向变化及其与生长轮密度相关性质的研究 ,结果表明 ,银杏木材平均微纤丝角为 1 8.5°,生长轮内早材微纤丝角较大 ,晚材较小 ;生长轮间沿径向呈减小趋势。木材微纤丝角与生长轮年龄、生长轮宽度、生长轮密度之间有较密切关系 ,建立了 5个相关模型 ,为银杏用材林的定向培育和木材加工利用提供依据

Abstract

In this paper, the microfibril angle and growth ring density of Ginkgo ( Ginkgo biloba ) wood were studied. The results showed that the microfibril angle of Ginkgo was 18.5°, the variation trend was bigger in earlywood than latewood with inter ring while the trend was regularly decreased from pith to bark with intra ring. There was close relation among microfibril angle and cambium year and ring density, five models were established. The results of the study will be helpful to the cultivation and utilization of Ginkgo plantations.
