摘　　要：以12年生日本栗银寄品种为材料,选择剪去结果母枝长的1/2、1/3、1/4和抹除顶芽共4种修剪强度,开展修剪对日本栗生长发育影响试验。结果表明,以1/4强度处理增产效果最明显,具有抑制雄花数量、增加雌花数量、控制枝长伸长生长和增加枝粗及增加结蓬数量的综合效果;其次,去顶处理和1/3修剪处理也具备良好的抑制雄花数量、增加雌花数量、控制枝长伸长生长和增加枝粗及增加结蓬数量的综合效果;而1/2高强度修剪处理除有效控制雄花数量外,表现为减少了雌花数量、促进了枝长伸长生长等效应。Experiments were conducted on different pruning treatments on 12-year Castanea crenata Gimyose.The result showed that cutting 1/4 of bearing branch had the best effect of nut yield,because it had advantages of inhibiting male flowers,increasing female flowers,controlling elongation growth and enhancing diameter growth of branch and thus increasing seeding.Treatment of top cutting and cutting 1/3 of bearing branch had similar effect as the first treatment.Cutting of 1/2 bearing branch had disadvantage of decreasing female flowers,promoting elongation growth of branch except decrease of male flowers.
