| 中文摘要:为筛选适宜复合种植的玉米品种，在渭北地区以5个玉米品种（‘陕单650’‘延科288’‘榆单896’‘郑单958’‘陕单660’）为材料，按照大豆玉米4∶2（玉米种植密度为75 000株/hm2，大豆种植密度为150 000 株/hm2）的复合种植模式进行适宜复合种植玉米品种的筛选试验。结果表明：在大豆玉米4∶2的复合种植模式下，玉米品种‘陕单650’‘郑单958’综合表现较好，穗行数、行粒数较多，产量较高。‘陕单650’两年产量均位居前列（103 76.36 kg/hm2，9 716.64 kg/hm2），倒伏率较低（1.2%~1.65%），抗倒伏能力强于‘郑单958’。研究筛选出适宜复合种植的玉米品种，有助于玉米大豆复合种植模式的推广。 |

| Screening of Maize Varieties Under Soybean-Maize Strip Intercropping Conditions |

| Abstract:Under conditions of a large population and limited arable land resources in China,the soybean-maize strip intercropping model improves land-use efficiency and crop productivity,helping to mitigate constraints on grain production. To screen out maize varieties suitable for intercropping,five maize varieties (‘Shandan 650’‘Yanke 288’‘Yudan 896’‘Zhengdan 958’ and ‘Shandan 660’) were used as materials in the Weibei region. The suitability of these varieties for intercropping was assessed under a soybean-maize 4∶2 planting pattern (maize planting density:75 000 plants/hm2; soybean planting density:150 000 plants/hm2). The results showed that under the 4∶2 soybean-maize intercropping system,‘Shandan 650’ and ‘Zhengdan 958’ exhibited better overall performance,including more ears per plant,more grains per row,and higher yield. ‘Shandan 650’ ranked among the top in yield for two consecutive years (10 376.36 kg/hm2,9 716.64 kg/hm2),and had low lodging rate (1.2%- 1.65%),demonstrating stronger lodging resistance than ‘Zhengdan 958’. In this study,maize varieties were suitable for strip intercropping,thereby may help promote the maize-soybean strip interecropping model in the Weibei area. |
