摘　　要：本研究采用滴灌水肥一体化管理模式,在5个试验点、3个种植密度条件下基于产量对12个夏玉米品种进行筛选试验。结果表明,种植密度对穗粒数和百粒重影响显著,夏玉米品种间也存在差异;选择百粒重高、耐密性强的玉米品种在高密度(75 000株·hm^(-2))条件下更容易获得高产。在滴灌水肥一体化模式下,推荐玉米种植密度为75 000株·hm^(-2),推荐夏玉米品种为立原296、鲁单9088、隆平904、YF3240和登海1717。In this study, 12 summer maize varieties was screened based on yield at 5 test sites and under 3 densities by integrated drip irrigation and fertilizer management mode. The results showed that planting density had significant effects on grain number per ear and 100-grain weight, and they were also different among summer maize varieties. Maize varieties with high 100-grain weight and high-density tolerance were more likely to achieve high yield under high density(75 000 plants·hm^(-2)). Under the drip irrigation with water and fertilizer integration, the recommended planting density of maize was 75 000 plants·hm^(-2), and the recommended summer maize varieties were Liyuan 296, Ludan 9088, Longping 904, YF3240 and Denghai 1717.
