    三、高溫缺墒慎施肥  果實成熟前期施速效磷鉀肥既能提高果實品質，又能增強樹體抗病能力。但此期氣候一般幹燥
、溫wen度du高gao，土tu壤rang墒shang情qing不bu好hao。施shi肥fei後hou灌guan水shui若ruo不bu及ji時shi，由you於yu土tu壤rang水shui分fen不bu足zu
，根gen係xi吸xi收shou的de肥fei料liao濃nong度du大da，易yi出chu現xian施shi肥fei後hou葉ye緣yuan枯ku焦jiao，表biao現xian出chu鹽yan害hai症zheng狀zhuang。使shi葉ye片pian功gong能neng受shou損sun，影ying響xiang光guang合he作zuo用yong，進jin而er影ying響xiang果guo實shi品pin質zhi。同tong時shi葉ye片pian抗kang病bing性xing能neng降jiang低di。若ruo後hou期qi多duo雨yu，葉ye片pian病bing害hai發fa生sheng嚴yan重zhong，甚shen至zhi引yin起qi葉ye片pian早zao落luo。施shi肥fei應ying在zai灌guan水shui後hou土tu壤rang不bu粘zhan時shi適shi時shi施shi入ru，或huo施shi肥fei後hou及ji時shi灌guan水shui。
