| 摘 要： | 对红松人工林幼龄材与成熟材气干与全干时的干缩性能进行了测试和分析。结果表明：幼龄材与成熟材气干与全干时干缩系数相比，幼龄材的径向、弦向、体积干缩系数均大于成熟材；气干与全干时差异干缩都是成熟材小于幼龄材。在木材利用上尽量选择成熟材，以提高产品质量，实现较高的经济价值。

| Abstract: | The shrinkage of juvenile wood and mature wood of Pinus koraiensis plantation both in absolute-dried and air-dried conditions were analyzed. The results showed that the shrinkage between absolute-dried and air-dried course of juvenile wood was higher than that of mature wood. The difference shrinkage between absolute-dried and air-dried course of mature wood was lower than that of juvenile wood. In the course of wood utilization, mature wood should be selected in order to improve product quality and obtain higher economic value. |
