摘　　要：为系统探索蚕豆赤斑病防控策略,保护农田生态环境,2010-2011连续2年在重庆市3个区县进行蚕豆与马铃薯间作试验。结果表明,蚕豆与马铃薯多样性种植能有效控制蚕豆赤斑病的发生,改善蚕豆产量构成因素,从而提高产量和经济效益。蚕豆与马铃薯间作行比为2∶2时对蚕豆赤斑病的防控效果最好,发病率与病情指数分别为46.5%和26.3,在此模式下经济效益最大,纯收入达18 454.9元/hm2。The present experiment was conducted to investigate the strategies for prevention and control of faba bean chocolate spot disease and protect the farmland ecological environment. Intercropping of faba bean and po- tato were made in three counties of Chongqing from 2010 to 2011. The results showed that intercropping can ef- fectively control faba bean chocolate spot disease and improve the yield constitution factors of faba bean, thereby promoting yield as well as economic efficiency. When 2 lines of faba bean and 2 lines of potato were intercropped, Prevention and control efficiency was the highest, with disease incidence and disease index of 46.5% and 26.3. and 18 454.9 yuan/hm2 economic income of faba bean, respectively.
