In recentyears，with the release and implementation of the“Zero Fertilizer Use Zero Growth Action Plan by2020”，fertilizer reducing and efficiency increasing have become an important way to develop green and high quality agriculture in China. Humic acid urea has been used as a new element for agricultural transformation and upgrading dueto its unique advantages.However，there are still many problems to be solved in the production of humic acid urea and its application and promotion in agricultural production and non-point source pollution prevention and control. Under the policybackground of agriculture with fertilizer reducing and efficiency increasing for greendevelopment，this paper systematicallyreviewed the research progress of the activation methods of humicacid，the mechanism of action of humic acid andurea，theprocessingtechnology，field application effects and the prevention and control of non -point source pollution of humic acidurea，proposed the problems existing in the production of humic acid urea and recommendations for new product developmentfocus and application promotion，which will provide reference for the use of zero -growth action plan for chemical fertilizers and agricultural non-point source pollution prevention and control.
