摘　　要：为实现玉米间作马铃薯立体种植模式的产量和产值最大化,进行了模式不同行比配置试验,筛选出较单作马铃薯和单作玉米增产程度最高的玉米马铃薯行比结构。研究结果表明:行比(玉米:马铃薯)为1:7的配置能够保证马铃薯在间作环境下实现其群体生产能力;又能够利用马铃薯上层的光热气资源提升玉米产量,最大程度的发挥玉米的单产潜力;1:7配置条带间光合有效辐射、作物叶片叶绿素含量、叶片氮素含量等生理指标和生物、产量性状的测定值均高于其他行比处理。In order to achieve the maximum yield and production value of maize-potato intercropping model, different row number ratio configurations were used to screen out the configuration for the maximum yield increase. The results showed that the optimal row number ratio （maize： potato） was 1：7, which could achieve the group production capacity of potato and increase the yield of maize by the upper heat resource of potato. This configuration could develop the yield ability of maize at the greatest degree, the photosynthetic available radiation, leaf chlorophyll content, leaf nitrogen content, and biological determination values and yield trait were higher than that of other configurations.
