摘　　要：我国杨树人工林面积位居世界之首,开展杨树修枝可以显著提高杨树人工林的经济效益和生态效益。目前,国内外尚未对杨树修枝研究进展进行评述。笔者论述了杨树修枝的理论基础,对杨树修枝技术以及杨树修枝效果进行了探讨,分析了修枝对杨树生长、生理、干形和材质的影响。同时指出了我国杨树修枝存在的不足,并提出了展望。Poplar plantation area in China is the largest in the world,and its the economic and ecological benefits could be significantly improved by Poplar pruning. At present,the research progress of Poplar pruning has not been reviewed. The theoretical basis,technology and effect of Poplar pruning were discussed in this paper. The effects of pruning on growth,physiology,stem form and timber quality of Poplar were analyzed. Meanwhile,the shortcomings of Poplar pruning in China were pointed out and the prospect of Poplar pruning was put forward.
