Abstract:

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.
