| 摘 要： | 2006年对安徽沿江地区杨树黑斑病流行规律进行了调查研究。结果表明,杨树黑斑病是一个多循环病害,其季节流行曲线呈多峰曲线;影响病害流行的关键因子是降雨量和湿度,当出现持续一周以上的高温无雨干旱天气,病害明显受到抑制,而当出现降雨、温度下降时,病情迅速扩展,病害加重。

| Abstract: | The epidemic law of polar black spot disease in Anhui area along Yangtze River was investigated and studied in 2006.The results showed that polar black spot disease was a polycyclic disease with seasonal epidemic curve showing as multi-peak curve.The key factors influencing disease prevalence were rainfall and humidity.When the drought weather with higher temperature and without rain lasted for more than a week,the disease was obviously inhibited.When the rainfall occurred and the temperature descended,the disease expanded rapidly and aggravated. |
