摘　　要：福本脐橙、早金甜橙、晚棱脐橙树冠喷施600倍氨基酸钙和卡拉脐橙树冠喷施1000倍硝酸钙,对果实油斑病发生率及外观品质的影响进行了研究,结果表明:树冠进行钙处理显著降低了福本脐橙、早金甜橙、晚棱和卡拉脐橙果实油斑病总发生率,尤其是油斑病一级发生率.果实油斑病总发生率分别由80%、80%、75%和82%降低到50%、25%、29%和39%,但对降低油斑病二级发生率的效应不一致.喷施氨基酸钙和硝酸钙同时促进了福本脐橙、早金甜橙、晚棱和卡拉脐橙果实的着色.The effects of foliar spraying 600 × calcium amino acids on Fukumoto navel orange （Citrus sinensis Osbeck cv.Fukumoto navel orange）,Lane＇s late navel orange （C.sinensis Osbeck cv.Lane＇s Late navel orange）,and early gold sweet orange （C.sinensis Osbeck cv.early gold sweet orange）,and 1000 ×calcium nitrate on CaraCara Navel orange （C.sinensis Osbeck cv.Cara Cara Navel orange） on oleocellosis development and external quality of citrus fruit were studied.The results showed that calcium treatment significantly reduced the total occurrence of rind oleocellosis,especially for 1st grade incidence of oleocellosis.oleocellosis incidence of Fukumoto navel orange,Lane＇s late navel orange,early gold sweet orange and CaraCara navel orange fruit decreased from 80%,80%,75% and 82% to 50%,25%,29% and 39%,respectively.However,the 2nd grade incidence of oleocellosis changed irregularly.At the same time,the calcium treatments were found to improve fruit color.
