摘　　要：为探索玉米和马铃薯多样性种植对玉米主要病害的控病效果,对玉米和马铃薯不同间作模式的控病作用进行研究。结果表明:玉米和马铃薯间不同的种植模式下,玉米大斑病、小斑病的病情指数均有所下降。对玉米大斑病的防治效果在12.15%～20.12%;对玉米小斑病的防效达10.93%～21.12%;试验还证明,不同种植模式的玉米马铃薯多样性种植产量均高于单作玉米或马铃薯,其土地当量比在1.19～1.28。To grope the effects of intercropping of maize with potato On maize disease control, the effect of dif- ferent intercropping patterns of maize and potato on controlling disease was studied. The results showed that maize/potato intercropping systems were helpful for maize disease control; The control efficacy of northern leaf blight reached 12.15 % - 20. 12 % and that of southern leaf blight reached 10.93 - 21. 12 %. Moreover, it proved that the intercropping patterns could impr0ve the yield compared to that of maize or potato monocul- ture. The land equivalent ratio （LER）was 1.19-1.28.
