田间调查比较马铃薯与玉米不同套种模式对马铃薯青枯病的控制作用结果表明,马铃薯套种玉米可减少青枯病病菌在株行间的蔓延,抑制马铃薯青枯病的发生。套种田块的青枯病发生率、大中薯减产率和单株减产量均低于纯种田块。马铃薯与玉米二套二种植模式对马铃薯青枯病的防治作用最为明显,发病率仅为纯种模式的60%左右。
Field investigation comparing the control effects of different interplanting patterns of potato and maize on potato bacterial wilt The results showed that potato intercropping corn could reduce the spread of bacterial wilt bacteria and reduce the occurrence of potato bacterial wilt. Set of farming block the incidence of bacterial wilt, yield reduction of large and medium-yield and single plant were lower than pure farming plots. Potato and corn two sets of two planting modes of potato bacterial wilt prevention and treatment of the most obvious effect, the incidence of only about 60% of the purebred mode.
