摘　　要：该试验以‘岳冠’苹果为试材,研究砧木和叶面喷钙对‘岳冠’苹果水心病发病率的影响。结果表明,以MAC9为砧木的苹果水心病自然发生率最低,为8.75%。叶面喷钙处理发生率最低的是以MAC9为砧木的,为5.65%;次低的是以山定子为基砧、GM256为中间砧的,为8.15%,且喷钙的防效最高。生产上应当选择MAC9为砧木,或山定子作基砧、GM256为中间砧。叶面喷钙对苹果水心病的防效较低,应改叶面喷肥为土壤施用。In this experiment,‘Yueguan’apple was used to study the effects of different stocks and foliar spraying calcium on the incidence rate of apple water core.The result showed that natural incidence rate of fruit apple water core with the rootstock of MAC9 was the lowest,the value was 8.75%.In the treatment of foliar spraying calcium,the lowest incidence of apple water core was the rootstock of MAC9,the value was 5.65%;Secondly,it was relatively lower that was with the interstock of GM256 and rootstock of Malus baccata Borkh,that value was 8.15%and the best control effect.In fruit production,‘Yueguan’apple tree with the rootstock of MAC9 or interstock of GM256 and rootstock of Malus baccata Borkh were more suitable.The control effect of foliar spraying calcium on apple water core is low,so foliar spraying fertilizer should be changed to soil application.
