- 摘要:
- 通过对玉米弯孢菌叶斑病(Curv ularia lunata(Wak ker)Boed)时间(季节)流行动态和空间流行动态的系统研究, 绘制出时间流行曲线和空间流行曲线。研究结果表明, 相同菌株在不同玉米品种上及不同菌株在相同玉米品种上的致病性和发展速度有差异, 并随着调查时间的延后, 病情指数有增加趋势, 流行曲线经过升高— 平稳的循环过程达到高峰值, 8 月下旬至9 月初各个品种均达到发病高峰。玉米弯孢菌叶斑病以中心传播方式进行传播, 随着距菌源中心距离的增大, 东、西、南、北各个方向的病情指数均有降低趋势。不同发病时期每个距离调查点的不同方向病情指数存在差异, 距菌源中心较远处, 东向比西向发病重, 而发病前期和发病中期南向比北向发病重, 发病后期距菌源中心近处各个方向无差异。
