在甘肃中部沿黄灌区，研究了马铃薯与大豆套作模式下5种不同幅比（马铃薯/大豆：1.0/0.5、1.2/0.3、0.8/0.5、1.0/0.3、0.8/0.3）对作物产量性状及经济效益的影响。结果表明，套作大豆的单株粒数与产量呈极显著正相关，单株粒数对大豆产量的直接作用最大；套作马铃薯单株薯重与产量呈显著正相关，单株薯重对马铃薯产量直接作用最大。在总带宽1.3 m、幅比1.0/0.3的套作模式下，作物产量、产值及纯收入均高于其他模式，具有较高的推广价值和增产潜力。

In this study,single radom-plot design was conducted to study the effect of five different bandwidth including 1.0/0.5,1.2/0.3,0.8/0.5,1.0/0.3,0.8/0.3 on yield and economic benefit in early potato intercropping soybean in Gansu irrigation districts along Yellow River . The results indicated that the yield of relaying soybean was positively associated with the number of seed per plant significantly . The yield of relaying early potato was positively associated with the tuber weight per plant significantly . It showed that 1.0/0.3 was the moderate system which can be extentioned in Gansu Irrigation Districts along Yellow River . The high yield of crop production can be got by improving the photo syrathetic .
