| 中文摘要: |
| 2022～2023年在陕西关中西部灌区以小麦新品种“西农511”为供试材料，采用随机区组试验设计，设置6个播期，探究不同播期对“西农511”生长发育和产量的影响，明确“西农511”最佳播期，旨在进一步丰富和完善关中西部灌区“西农511”高效稳产栽培技术及进一步的推广应用提供理论依据和技术支撑。结果表明，随着播种时间的推迟，“西农511”越冬期、拔节期和孕穗期的株高、叶龄、单株分蘖数、单株次生根数量显著下降(P<0.05)，进而导致小麦产量显著降低 (p<0.05)。方差分析表明，10月5日播种的“西农511”产量最高（745.6 kg/667m2），显著高于10月10日以后播种的小麦产量。在陕西关中西部地区，“西农511”小麦品种最佳播期为10月5日~10日。 |
| 英文摘要: |
| From 2022 to 2023, a new wheat variety "Xinong 511" was selected as a material in the central and western irrigation regions of Guanzhong, Shaanxi Province. Six sowing dates were set,and a randomized block experiment design was conducted to explore the effects of different sowing dates on the growth, development and yield of "Xinong 511", and to determine the optimal sowing dates of "Xinong 511". The aim is to further enrich and improve the high-efficiency and stable yield cultivation technology of "Xinong 511" in the western Guanzhong irrigation area, and provide a theoretical basis and technical support for further extension and application. The results showed that plant height, leaf age, tillering number per plant and rooting number per plant of "Xinong 511" decreased significantly with the delay of sowing time (p<0.05), resulting in a significant decrease in wheat yield (P<0.05).Variance analysis showed that the yield of "Xinong 511" sown on October 5 was the highest (745.6 kg/667m2), which was significantly higher than that of wheat sown after October 10. In the western region of Guanzhong, Shaanxi, the optimal sowing date for "Xinong 511" is October 5~10. |
