| 中文摘要: |
| 本研究对河套地区16个玉米品种进行了农艺性状及产量的比较分析，旨在以筛选出适应性强、产量高、质量优的品种，促进该地区玉米产业的可持续发展。通过田间试验与详细的数据分析，深入探讨了株高、果穗特性、生育期等农艺性状对玉米产量与质量的影响。结果表明，不同玉米品种间存在显著的产量和农艺性状差异，部分品种如金科002、新农006及金科003展示了较高的产量潜力与稳定性，而垦玉1723和盛玉628等品种虽产量稳定但整体较低，不适合高产目标种植。在抗逆性方面，大部分品种对茎腐病、空秆率、穗腐病及丝黑穗病等主要病害的抗性均为100%，展现了良好的抗病性。然而，少数品种在特定病害上的发生率轻微增加，但总体表现出较强的抗逆性。农艺性状的比较揭示了显著的品种间差异，特别是在穗长和穗粗方面的优异表现，可能对产量提升有积极影响。研究结果为河套地区玉米种植提供了科学依据，并对玉米品种改良及种植管理提供了重要参考。 |
| 英文摘要: |
| This study focuses on maize and aims to compare the agronomic traits and yields of different maize varieties in the Hetao region. It aims to identify varieties with strong adaptability, high yield, and superior quality, thereby promoting the sustainable development of the local maize industry. Through field trials and detailed data analysis, this study explored how key agronomic traits, such as plant height, ear characteristics, and growth period, affected maize yield and quality. The study found that there were significant differences in yield and agronomic traits among different maize varieties. Varieties such as ‘Jinke 002’, ‘Xinong 006’, and ‘Jinke 003’ showed high yield potential and stability, whereas ‘Kenyu 1723’ and ‘Shengyu 628’, although stable in yield, had lower overall yields and may not be suitable for high-yield cultivation. In terms of stress tolerance, most varieties showed no incidence of major diseases such as stem rot, ear rot, and head smut, and exhibited a 0% empty stalk rate, indicating good disease resistance. However, a few varieties showed a slight increase in the incidence of specific diseases but generally exhibited strong stress tolerance. The comparison of agronomic traits revealed significant differences among varieties, particularly in ear length and ear width, which may positively affect yield. The results of this study provide a scientific basis for maize cultivation in the Hetao region and offer important references for variety improvement and cultivation management. Future research should continue to explore varietal adaptability under different environmental conditions and enhance yield and stress tolerance through breeding strategies to achieve efficient and sustainable development of the maize industry. |
