摘　　要：由于苹果品种多不抗斑点落叶病,目前国内外大都依靠化学防治来控制该病。但对其季节流行动态和爆发成因,以及在何种气象条件下使用农药才能获得最佳防治效果,尚缺乏系统研究。本研究以田间试验为主,通过对病害的逐日系统调查,将所得数据借助计算机进行统计分析,旨在明确生长季苹果斑点落叶病的季节流行动态和爆发成因(即病原菌大量侵染的决定性天气条件),为苹果生产提供可行的防治建议并为该病害的预测奠定基础。Alternaria Leaf spot is a severe epidemic disease world wide.Since most of apple varieties do not resist to the disease, it is commonly controlled with chemicals. Up to now, the dynamic and outbreaking causes of the disease together with the climatic conditions under which the best control effect could be got are still unknown.This study, based on field experiments, is to determine the seasonal dynamics and outbreaking causes of the disease by means of data processing and analyzing with computer so as to provide control suggestions for prodcution and research.
