中文摘要：

利用活立木上树叶的蒸腾作用可以将树干中的水分排出。以新疆杨为试材,依据树叶蒸腾作用理论,采取切断试材水分来源的手段,定期取样,分析树干中不同部位含水率变化规律,探讨了活立木生理干燥的效果。研究结果表明：新疆杨进行边材切割和剥皮处理可以实施活立木的生理干燥,其边材最终含水率约达20%,心材含水率约达29%。

英文摘要：

The transpiration of leaves on trunk can remove the water in the trunk. In this paper, based on the leaf transpiration theory, the physiological drying of the populus alba standing trunk is achieved. The results show that for the populous alba with sapwood cutting and bark peeling, the physiological drying of the standing trunk can be achieved. The final moisture content of the sapwood can reach about 20%, and the heartwood content can reach about 29%.
