摘　　要：为探究较好的谷子大豆间作模式,选用谷子农大8号和大豆晋豆25号作为试验材料,在不施氮肥的基础上设置谷子和大豆间作比例为6∶0(T1)、2∶4(T2)、3∶3(T3)、4∶2(T4)4个处理,检测不同间作比例对谷子生物性状和产量的影响。结果表明,与单作模式对比,合理间作模式可以有效提高谷子株高、茎粗、叶面积,同时提高谷子干物质积累,在间作比例为2∶4(T2)、3∶3(T3)处理下产量显著提高,其中,谷子和大豆间作比例为2∶4时,谷子产量最高,为6 716.27 kg/hm^2,增产效果最明显,间作效果最好。谷子和大豆间作具有一定的实践推广意义。To explore a better intercropping model of millet and soybean, the varieties Nongda 8 and Jindou 25 were selected as test materials for millet and soybean, and the intercropping ratio of millet and soybean was set without nitrogen fertilizer. There were 4 treatments,which was 6∶0(T1), 2∶4(T2), 3∶3(T3), 4∶2(T4), and 3 repetitions. The effects of different intercropping ratios on the biological characteristics and yield of millet was detemined. The experimental results showed that compared with the single cropping mode, a reasonable intercropping mode could effectively increase plant height, stem thickness and leaf area of millet. At the same time, dry matter accumulation of millet was increased, and the yield was significantly increased under T2(2∶4)and T3(3∶3)treatments. Among them,the yield of millet and soybean intercropping ratio of 2∶4 was the highest,which was 6 716.27 kg/hm^2, and the yield increasing effect was the most significant. The test results show that millet soybean intercropping is a better way of intercropping. Under the current situation of rare people implementing millet soybean intercropping, it has certain practical significance.
