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.
Abstract
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,develop-ment and yield of"Xinong 511",and to determine the optimal sowing dates of"Xinong 511".The aim is to fur-ther enrich and improve the high-efficiency and stable yield cultivation technology of"Xinong 511"in the west-ern Guanzhong irrigation area,and provide a theoretical basis and technical support for further extension and ap-plication.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 de-crease 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.
