With the continuous increase of rice production, more and more attention has been paid to different fertilizer management technologies, especially increasing the amount of nitrogen fertilizer and increasing the yield of crude fertilizer to promote flowering fertilizer. In this paper, through three years of research on nitrogen fertilizer operation technology in rice, the effects of different fertilizer management on the quality and yield of rice population were analyzed. The effects of different fertilizer management techniques on rice yield were discussed.
