摘要
总结了山东济宁地区灰飞虱的发生特点和水稻条纹叶枯病的发生规律。定点调查和相关因子分析表明,水稻条纹叶枯病大发生的原因主要有传毒昆虫数量大、栽培方式的变化、感病品种种植面积大、病原致病性发生变异、防治方法不当等,提出通过种植抗病品种、改变栽培方式、加强种植管理等方法预防病害发生,采用药剂浸种、秧田防治、大田防治等方法进行统防统治。
The occurrence characteristics of brown plant hopper and the occurrence rules of rice stripe disease in Jining district of Shandong province were summarized.
