| 为了筛选出适宜黄淮海地区种植的高密高产品种。以该地区种植的3个玉米品种为试验材料，通过株高、穗位、产量及经济效益等指标,综合考察不同种植密度在水肥一体化条件下的差异及原因。结果表明,金博士740株高矮、穗位低，抗倒伏能力强,较CK（C1210）相比，株高降低6.40%，穗位降低6.52%,从产量方面看，金博士740及H1820产量高，金博士740经济效益更显著。因此,在6 000株/667 m的密度下种植，金博士740在植株性状及产量效益方面表现更优，可以作为高密高产品种进行推广种植。 |

| This study aimed to screen maize cultivars suitable for high-density and high-yield cultivation in the Huang-Huai-Hai region. Three maize cultivars commonly grown in this region were selected as experimental materials. Three maize cultivars commonly grown in this region were selected as experimental materials. Under conditions of integrated water and fertilizer management, the effects of different planting densities were comprehensively evaluated based on plant height, ear position, grain yield, and economic benefits, and the underlying reasons for observed differences were analyzed. The results showed that ‘Jinboshi 740’ exhibited shorter plant height, lower ear position, and stronger lodging resistance. Compared with the control (CK, ‘C1210’), plant height and ear position were reduced by 6.40% and 6.52%, respectively. In terms of grain yield, both ‘Jinboshi 740’ and ‘H1820’ achieved relatively high yields, while ‘Jinboshi 740’ showed more pronounced economic advantages. In summary, when planted at a density of 6 000 plants per 667 m, ‘Jinboshi 740’ demonstrated better performance in plant morphological traits, yield, and economic returns, indicating its suitability as a high-density, high-yield maize cultivar for cultivation in this region. |
