| 大豆玉米带状复合种植是实现国家"增玉米、稳大豆"粮食稳产增产战略的关键技术模式。为了筛选出适合合阳县旱地大豆-玉米带状复合种植的大豆品种，以14个主栽大豆品种为试验材料，按照玉米(陕单650)、大豆行比 2∶4 间作，研究供试大豆品种的农艺性状、抗倒伏性以及产量。结果表明，参试大豆品种陕豆125产量最高，为150.67 kg/667 m2，但其抗倒性中等，落叶性一般，生育期较长，综合表现一般；中黄30、中黄318产量位居第二、第三，分别为134.05 kg/667 m2、125.87 kg/667 m2，耐荫抗倒、落叶性好，中早熟，产量高，综合表现优良；齐黄34、冀豆17、山宁17、北铁丰31抗倒性强、落叶性好、生育期中等，产量较高、综合表现好；汾豆93为无限结荚习性，倒伏严重，生育期长，产量最低，不适宜复合种植。 |

| Soybean-maize strip intercropping is a key technical model for implementing the national strategy of “increasing maize production and stabilizing soybean production” and ensuring stable and increased grain production. To screen soybean varieties suitable for soybean-maize strip intercropping in the rainfed dryland of Heyang County, 14 main soybean varieties were used as experimental materials. Maize (‘Shandan 650’) and soybean were intercropped at a row ratio of 2∶4 to study the agronomic traits, lodging resistance, and yield of the tested soybean varieties. The results showed that ‘Shandou 125’ had the highest yield, at 150.67 kg/667 m2, but its lodging resistance was moderate, and its leaf-shedding period and growth period were long; therefore, its overall performance was average. The yields of ‘Zhonghuang 30’ and ‘Zhonghuang 318’ ranked second and third, respectively, at 134.05 kg/667 m2 and 125.87 kg/667 m2. They were shade-tolerant, lodging-resistant, had good leaf-shedding ability, were mid-early maturing, and had high yields; therefore, ‘Zhonghuang 30’ and ‘Zhonghuang 318’ had the best overall performance.‘Qihuang 34’, ‘Jidou 17’, ‘Shanning 17’, and ‘Beitiefeng 31’ had strong lodging resistance, good leaf-shedding ability, a moderate growth period, and a high yield; therefore, they also had good overall performance. ‘Fendou 93’ had an indeterminate growth habit, suffered from severe lodging, and had a long growth period and the lowest yield. It is not suitable for intercropping. |
