摘要
应用生物协同进化论和稻瘟病流行动力学原理，界定出了绵阳市稻瘟病流行分布区域，提出了区域防治的概念，协调地实地了区域防治，规范了苗期、穗期关键技术环节，简化、优化稻瘟病系统控制技术；已在172．8万亩推广应用。
Based on the theory of biological cooperate evolution and the rice blast epidemic dynamics, the rice blast epidemic regions in Man-yang \vere determined. A notion of regional control has been put for-ward. Tbe Key technology during seeding and heading stage is specltied,and the rice blast systematic control techniques simplified and optinli-zed. Up to now, it has been successfully applied in an area of 115200 hectares.
