摘　　要：油茶林地郁闭、枝梢呈衰老态是低产油茶林中存在的一个普遍现象,修剪是消除此类现象有效且省力的丰产措施,但修剪技术灵活,难以为多数种植户掌握。为此,本文提出针对性强且易于实施的“开窗”式复壮修剪措施,详细阐述了相关的修剪思路、操作要领及其评价指标。该措施短期内可快速恢复树势,长期施行可改良树形,最终可大幅提高单株产量。Crown closure with weak top branches are common with low-yield Camelia oleijfera plantations and pruning is an effective and labor-saving measure to eliminate such phenomena and improve yield.In view of the fact that most growers may not be able to have a good command of flexible pruning techniques,a targeted and easily implemented windowed crown pruning measure is put forward in this paper with a detailed elaboration on the pruning idea,operating essentials and assessment index to facilitate rapid recovery of the tree vigor in the short run,tree structure improvement in the long run and eventual great yield increase per plant.
