高接梨已經是台灣一個相當重要之產業，一般越早上市價格越高，因此農民普遍提早接穗，然而由於提早接穗遇寒流時會造成成功率低而需要重複接穗，提高相當高之成本。為求提高梨產量，農民往往施肥過度，造成落果及腐爛嚴重，尤其雨季，所以如何改善其栽培管理方法以降低農民成本及提高收益相當重要。本研究即朝解決此二問題研究。The production of pear from high grafting of pear flower bud on lowland pear tree has been an important farm practices. The higher price with the earlier market makes the farmers doing the grafting as early as possible. The early grafting will face the high risk because the cold wind lows down the success ratio of grafting bud, and the heavy rain in April and May also damage the pear. How to increase the grafting success rate and decrease the rain damage are quite crucial to the profit reward from the production system. The objectives of this research will focus on the two problems by making foliar fertilizers and appropriate fertilization strategy to improve the profit from the growing system
