| 为探索适宜延安市应用的大豆玉米带状复合种植带型模式，2023年4~10月，以4∶2模式为对照，设置了6∶3模式、4∶3模式、4∶4模式三种带型模式，通过分析三种模式下大豆玉米带状复合种植的优势和产量，筛选出最适宜延安地区的大豆玉米带状复合种植带型模式，为延安市大豆玉米带状复合种植示范推广工作奠定良好的基础。结果表明，4∶3带型模式玉米单产最高（598.38 kg/667 m2），4∶4模式玉米单产最低（400.71 kg/667 m2），6∶3模式大豆单产最高（103.28 kg/667 m2），4∶4模式大豆单产最低（45.32 kg/667 m2）。通过试验结果分析，4∶4模式大豆、玉米667 m2减产比最高，4∶3模式大豆、玉米667 m2减产比较低且稳定，适宜在我市示范推广和种植,4∶2模式玉米667 m2减产比较低，适宜在我市大面积推广使用。 |

| To determine the most suitable belt pattern for soybean and maize intercropping in Yan’an,a field experiment was conducted from April to October 2023,using the 4∶2 belt pattern as the control. Three additional belt patterns—6∶3,4∶3,and 4∶4—were evaluated by analyzing their respective advantages and crop yields. The objective was to identify the optimal soybean-maize belt intercropping pattern for the region,providing a scientific basis for future demonstration and large-scale promotion.The results indicated that the 4∶3 belt pattern achieved the highest maize yield,reaching 598.38 kg per 667 m2,whereas the 4∶4 pattern resulted in the lowest maize yield (400.71 kg per 667 m2). For soybean,the 6∶3 pattern produced the highest yield (103.28 kg per 667 m2),while the 4∶4 pattern yielded the lowest (45.32 kg per 667 m2). Analysis of the yield reduction rates showed that the 4∶4 pattern exhibited the highest reduction in both soybean and maize yields,whereas the 4∶3 pattern demonstrated a lower and more stable yield reduction,making it suitable for demonstration and adoption in Yan’an. The 4∶2 pattern had a relatively low maize yield reduction rate,making it the most appropriate for large-scale application in the region. |
