修剪強度對楊桃產量及品質之影響

Abstract

楊桃經多年的開花結果後，由於枝條老化，而有開花著果不良或品質不佳的情形，因此擬由更新結果枝的方式，來促使枝條新陳代謝良好，以平衡各枝條生長勢力。試驗以強剪、中剪與一般修剪三種不同修剪量進行處理，第一次處理過後，強剪因著果面積減少，著粒數少，產量最低，中剪次之，一般修剪產量影響最少。 After many years of flowering and producing fruit, the aging branches will no longer easily flower and produce fruit or have bad quality. Need to refresh the fruiting branches to promote branches regeneration and balance the growing trend. Tested with heavy, medium and lightly pruning process. One year after heavy pruning, due to fruiting area diminish, fewer fruits, productivity is lowest, medium pruning is the next.
