In order to further clarify the yield and quality improvement effects of sulfur and magnesium fertilizers in winter rapeseed cultivation,and explore the reasons for the yield and quality improve-ment of rapeseed by applying sulfur and magnesium fertilizers,relevant research work was carried out in Xinyang region in 2019-2020 to provide scientific basis for rational magnesium and sulfur applica-tion in rapeseed.The experimental results show that compared with local fertilization,one-time appli-cation of sulfur magnesium fertilizer can reduce fertilizer application amount,reduce labor costs,pro-mote nutrient absorption and growth and development of rapeseed,increase the number of rapeseed seedlings,increase the number of pods,increase rapeseed yield,and improve economic benefits.
