摘  要:
由于森林资源总体质量的下降,木材生产中小径木所占比例越来越大。小径木因其径级小、材质不稳定等缺点,使用受到限制。如何充分开发和高效利用小径木资源,成为当前国内外学者普遍关注的问题。目前,小径木大多作为木片、造纸和人造板的原料,这种利用方式投资大、产品单一、资金回收慢、经济效益低。而将小径木经过优化选材、优化设计和优化工艺的方法,加工成集成材、重组木等,可改善或提高小径木材质,克服径级小、利用单一的缺点,满足市场对木材的旺盛需求。

摘  要:
Based on different drying schedule of wood,the drying evenness of small-diameter Larix gmelinii in polygonal cutting was experimental studied by using usual drying method.The result showed that the drying evenness of small-diameter Larix gmelinii in polygonal cutting was different under different drying schedule.Specifically,the drying period of usual drying method was long,but the drying evenness was good.When wave-drying and hard drying schedule were adopted,the drying evenness was worse than that of usual drying method.Moreover,the drying period and evenness of wave-drying were better than those of hard drying.Through this test,the wave-drying schedule was proved to use suitably for drying of small-diameter Larix gmelinii in polygonal cutting.
