摘要： 甜柿是台灣地區高經濟的果樹之一，單位面積收益頗高，但仍有樹勢因嫁接不親和而提早老化、肥培管理沒有依據準則、疏果標準未確立、生理障礙嚴重及不耐貯運等問題，本計畫擬自篩選適合砧木品種、建立葉片營養標準及結果密度、降低裂萼發生之道及改善處理作業，冀以獲豐產、優質及貯運力佳等經營流程。Sweet persimmon is the most important commercial fruit crop of Taiwan according to high return. The development potential for sweet persimmon in Taiwan is limited due to their incompatibility with rootstock, lacking in leaf nutrient standard, no information about crop load, serious physiological disorder, and high perishability. Our objective is to make appropriate selection from different lines for rootstock, to establish optimum leaf nutrient status and levels of crop loading, to decrease physiological disorder in fruit by cultivation practices, and to improve postharvest handling technology. Furthermore, the management program for stable yield, high quality and storability is obtained.
