Control Technology of Main Diseases and Insect Pests of Hanfu Apple in Faku Area

摘要: 寒富苹果是沈阳农业大学李怀玉教授1978年用东光 × 富士杂交选育而成的。1997年通过辽宁省农作物品种审定委员会审定。随之，在辽宁中北部地区快速发展。法库县从1996年开始引进寒富苹果，由于该品种综合性状优良，目前寒富苹果已成为法库县苹果的主栽品种，到2018年末，全县栽培面积已达3.9万亩。虽然寒富苹果适应性良好，抗逆性强，但近年来也受到一些常见病害影响，如苹果树腐烂病、苹果褐斑病。果树轮纹病、霉污病等，造成有的果园各种病虫危害严重，果品质量下降，轻者造成减产，重者砍树毁园。现将法库地区寒富苹果常见病害发病规律及防治方法，总结如下。
