摘　　要：采用L9(34)正交设计,研究马铃薯品种、马铃薯与玉米的间距和带宽、马铃薯窝距对马铃薯和玉米产量的影响。结果表明,马铃薯品种、马铃薯与玉米的带宽是影响总产量的关键因子,其次是马铃薯窝距,马铃薯与玉米的间距对总产量的影响最小;当采用渝薯1号,马铃薯窝距为40 cm,马铃薯与玉米的间距为20 cm、带宽为120 cm时,总产量最高、达30 981.4 kg/hm2。L9（3^4） orthogonal design was used to research the effect of potato varieties, the spacing and bandwidth of potato and corn, the distance between the potatoes on the production of potatoes and corn. The research showed that potato varieties and bandwidth were the key factors for the total production, followed by potato nest distance, the spacing of potato and corn had the smallest effect. The total production achieved the highest（30 981.4 kg/h㎡） when the potato variety was chongqing potato 1, the potato nest distance was 40 cm, the spacing was 20 em and the bandwidth was 120 cm.
