Abstract: In order to master the utilization rate of N P and K Fertilizer and in winter wheat, obtain the best fertilization scheme, fertilization proportion and fertilization method of winter wheat, and promote the reduction and efficiency increase of chemical fertilizer in a solid and orderly manner. From 2020 to 2021, the field experiment of fertilizer utilization rate was carried out on winter wheat in Yongji city. Through the comparative test and analysis of field N P and K fertilizer, the current situation of fertilizer utilization rate of winter wheat in Yongji City was mastered, so as to provide sufficient scientific basis for weight loss and efficiency increase.
