据研究，平圩区稻瘟病为秋季重发型，明显区别于皖南、皖西山区早稻重发型；夏季经作茬晚稻是平圩区双晚发病的重点对象田；晚稻旱育秧苗叶瘟发生重。在分析品种、栽培措施（播栽期、施肥、育秧方式）和气候等流行因素的基础上，提出慎选良种、科学栽培、结合药剂预防和治疗的一整套控制技术。 According to the research, the rice blast in Pingxu district is the autumn recurrence type, which is obviously different from the early rice recurrence in Wannan and Wanxi mountains. The late cropping rice in late summer is the key target field of double pollination in Pingxu district. . On the basis of analyzing the epidemic factors such as variety, cultivation measures (sowing date, fertilizing, seedling raising) and climate, we put forward a set of control technologies that are carefully selected varieties, scientifically cultivated and combined with drug prevention and treatment.
