摘要
对匍茎剪股颖草坪禾草云斑病的病原与影响发病的因素进行了观察研究，表明，温度影响病害发生，当日均温达１８℃左右，相对湿度为８０％时开始发病，病害发生的最适温度为１９～２２℃，高湿是导致病害发生的关键因素之一。
The infestation of Rhynchosporium secalis to Agrostis stolonifera was investigated. The results showed that both air temperature and humidity affected the occurrence of infestation. The symptom appeared when average daily temperature was over 18 ℃ and the relative humidity was over 80%. The optimum temperature ranged from 19 ℃ to 22 ℃. High humidity was key factor to the disease.
