摘　　要：为探究青贮玉米-大豆间距及行比配置对玉米大豆带状复合种植产量和土壤养分的影响,以玉米铁391K和大豆东豆9为试验材料,采用二因素裂区试验设计,玉米-大豆间距设50、60、70 cm等3个水平、行比配置设2∶4、4∶4等2个水平,分析不同玉米-大豆间距及行比配置对玉米-大豆复合体生物产量及土壤养分含量的影响。结果表明,60 cm玉米-大豆间距和4∶4行比配置有利于玉米-大豆复合种植体优化根系分布,有利于玉米大豆根际土壤养分的提高,玉米生物产量及玉米-大豆复合体生物产量最高。综上所述,在内蒙古通辽市西辽河平原青贮玉米-大豆复合种植时,60 cm玉米-大豆间距、4∶4行比配置模式是相对适宜的复合种植方式。In order to investigate the effects of silage corn-soybean spacing and row ratio configuration on the yield and soil nutrients of corn-soybean strip-cropping,we used corn Tie 391K and soybean Dongdou 9 as experimental materials,and adopted a two-factor split-area experimental design,with three levels of corn-soybean spacing of 50 cm,60 cm,and 70 cm,and two levels of row-ratio configuration of 2∶4 and 4∶4,to analyze the effects of different corn-soybean spacing and row-ratio configurations on the biological.Yield and soil nutrient content of the corn-soybean composite.The results showed that the 60 cm corn-soybean spacing and 4∶4 row ratio configuration were conducive to the optimization of root distribution in the corn-soybean composite planting,which was conducive to the improvement of soil nutrients in the inter-root zone of corn and soybeans,and resulted in the highest biological yield of corn and the highest biological yield of the corn-soybean composite.In conclusion,silage corn-soybean complex planting in the Xiliaohe Plain of Tongliao City,Inner Mongolia,60 cm corn-soybean spacing and 4∶4 row ratio configuration were relatively suitable complex planting methods.
