In order to further promote the soil testing formula fertilization technology, understand the fertilization rules of rice in the local area, and the impact of different fertilization levels on the fertilizer utilization efficiency and yield of rice, improve fertilizer utilization efficiency, and increase rice yield. This experiment combines the soil testing formula fertilization and fertilizer correction experiment in Yongxing County to study the effects of soil testing formula fertilization on rice yield and fertilizer utilization efficiency. The results showed that the utilization rates of nitrogen, phosphorus, and potassium fertilizers in the conventional fertilization area were 30.64%, 14.96%, and 47.87%, respectively; The utilization rates of nitrogen, phosphorus, and potassium fertilizers in the formula fertilization area are 34.42%, 19.45%, and 53.87%, respectively. By promoting and popularizing soil testing formula fertilization, the utilization rates of nitrogen, phosphorus, and potassium in late rice soil testing formula fertilization increased by 3.78, 4.49, and 6.0 percentage points respectively compared to conventional fertilization.
