摘　　要：为明确辽宁省东港地区稻瘟病流行规律及其与不同气象因素的相关性,于2016~2021年连续对东港市稻瘟病菌孢子及气象因素进行了监测,经分析表明:孢子数量与稻瘟病的发生呈正相关,与温度、湿度、降水为正相关,与风速呈负相关。把握防治时期,控制田间孢子数量是防治水稻稻瘟病的关键。To clarify the epidemiological pattern of rice blast in Donggang region of Liaoning Province and its correlation with different meteorological factors,this study continuously monitored rice blast spores and meteorological factors in Donggang from 2016 to 2021,and the analysis showed that spore number was positively correlated with the occurrence of rice blast,positively correlated with temperature,humidity,and precipitation,and negatively correlated with wind speed.Grasp the control period and control the number of spores in the field is the key to control rice blast.
