| 摘 要： | 在对生长季苹果斑点落叶病发生情况进行逐日系统调查的基础上,结合气象数据的收集,通过对生长季中多个病原菌关键侵染日天气条件的分析、归纳和总结,提出了苹果新梢旺盛生长期,斑点落叶病菌大量侵染的决定性天气条件为:在24 H内,降雨量(MM)与降雨持续时间(H)的乘积至少要达到12,且降雨开始后空气相对湿度维持在90%以上至少10 H。

| Abstract: | Systematic investigations were made on epidemics of Alternaria blotch in apple and the daily meteorological data during the whole growing season were collected as well.Based on the analyzing for the weather conditions of all the days which caused disease eruptions in detail,the crucial weather conditions for mass infection of Alternaria mali during growing season were summarized as follows: Within 24 hours,the product of rainfall(mm) and raining duration(hrs) must be no less than 12,and the duration of high relative humidity(>90%) soon after the rain must be at least 10 hrs. |
