中文摘要：

为了探究甘肃省渭源县马铃薯晚疫病流行规律,有效地防治马铃薯晚疫病,在甘肃渭源县对马铃薯晚疫病田进行了一个生长季节的监测和调查。结果表明：不同品种晚疫病发生程度不同,晚熟品种比早熟品种晚发生,早熟品种抗病性比晚熟品种差;马铃薯晚疫病的流行与气象条件的关系中,相对湿度、降雨量和马铃薯晚疫病流行呈正相关,日照时数与马铃薯晚疫病流行呈负相关,其中相对湿度为晚疫病流行的主导因素,在这期间温度不是当地晚疫病流行的主导因素。

英文摘要：

In order to effectively control potato late blight, we studied the epidemiology of potato late blight by monitoring and observing potato late blight in a growing season of Weiyuan County of Gansu Province. The comparison research of occurrence patterns of potato late blight for different potato varieties showed that resistance of late maturing variety was stronger than that of early maturing variety. After observation of the relationship between the epidemiology of the late blight and the meteorological conditions, it revealed that there was a positive correlation of relative humidity and rainfal with the epidemiology of late blight, with a bigger correlation coefficient for relative humidity, whereas the sunshine hours were negatively related with the epidemiology. However, temperature was not found to have a significant effect on the epidemiology of potato late blight in this period.
