摘　　要：就不同修剪强度对二次结实板栗生长发育的影响作了试验研究,结果表明对于板栗结果母枝的修剪以1/3、1/4和1/2修剪强度能极显著减少雄花数量,1/4和去顶处理具增加雌花数量效应,1/3、1/4和去顶处理均具一定的抑制新梢伸长生长和促进枝粗生长作用,1/4修剪强度和去顶处理具增加第一次结蓬数量效应,1/2修剪处理则使二次结实板栗结蓬数量大大降低,此外,随修剪强度的增加其第二次结蓬数也增加,至1/3修剪强度时达到峰值。Experiment of effect of different pruning intensity on growth and development of secondary Bearing Castanea mollissima resulted that bearing branch pruned 1/3,1/4 or 1/2 would reduce effectively male flowers, pruned 1/4 and topped would increase female flowers, pruned 1/3, 1/4 and topped had effect on elongation and diameter growth of new branch, pruned 1/4 and topped treatment had effect on first setting, pruned 1/2 on decrease of the second setting. Along with intensity of pruning, the second setting increased, especially pruned 1/3.
