Effects of Different Sowing Dates on Growth,Development and Yield of Wheat Variety'Xinong 511'
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.
