This experiment was conducted in Quanjiao County. Using the indica-type three-line hybrid rice variety Jiuyouyuehesi as the material, five fertilization treatments were set up to study the effects of different ratios of slow-release and controlled-release nitrogen fertilizers on rice yield, nitrogen fertilizer utilization rate, and economic benefits. Slow-release and controlled-release nitrogen fertilizers could effectively coordinate the population structure of rice, improve nitrogen absorption efficiency, and reduce nitrogen loss. This was a fertilization mode suitable for the simplified and efficient production of rice in Quanjiao County.
