To study the impact of global warming on the yield and quality of winter wheat, field scientific experiments are carried out at Xuzhou Agro-meteorological Station of Jiangsu from 2017 to 2022. There are four sowing dates each year with different temperature during the growing season of winter wheat, while the winter wheat variety, soil physical and chemical properties, and agriculture measures are all the same. Therefore, the yield structure and quality of winter wheat are mainly influenced by climate change. It shows that the average temperature increases 0.1℃ to 1.7℃ during the growing season of winter wheat at different sowing dates during 5-year field experiments. The increasing temperature has an impact on the yield structure, and there is a significant negative influence on the number of grains per ear of winter wheat, with a correlation coefficient of -0.49 (P |
