摘　　要：该试验以‘岳冠’苹果为试材,研究叶面喷施不同钙肥对果实水心病的防治效果。结果表明,几种钙肥均能降低果实水心病病果率和病情指数,且有随喷施次数的增加效果越好的趋势。4种钙肥中以果蔬钙肥防治效果最好,病果率最低,不同喷施次数依次为10.00%、8.26%、8.15%;病情指数最低,依次为1.85%、1.48%、1.11%;防效最高,依次为68.80%、75.04%、81.28%。其他依次为优钙、卡露里钙和培尔钙。喷施方法依次为套袋前3次,套袋至摘袋前2次,摘袋后1次。In this experiment, ‘Yue Guan＇ Apple was used to study the effects of foliar spraying of different calcium fertilizers on fruit water heart disease. The results showed that several calcium fertilizers could reduce the disease fruit rate and disease index of fruit water heart disease,and the effect was better with the increase of spraying times. The effect of ‘Guo Shu Gai＇ on 4 kinds of calcium fertilizer was the best,the rate of disease fruit was the lowest,and the number of spraying was 10%,8.26% and 8.15%;The disease index was the lowest,followed by 1.85%,1.48% and 1.11%;The highest control efficiency was 68.80%,75.04%and 81.28% respectively. Others followed by ‘You Gai＇‘Ka Lu Li Gai＇‘Pei Er Gai＇. The spraying methods were 3 times before bagging,2 times from bagging to picking bags,and 1 time after picking bags.
