As the paramount phosphate fertilizer commodity in China，ammonium phosphate holds significant importance in safeguarding national food security. To enhance the efficacy of ammonium phosphate and address the escalating deficiency of sulfur nutrients in the soil，sulfur-containing ammonium phosphate products have emerged. The article succinctly outlined the current sulfur supplementation in ammonium phosphate，covering both elemental sulfur sources and sulphate sources，from the perspectives of sulfur addition form and sulfur addition mode，along with the corresponding process flow under different sulfur sources. Through comparative analysis of agronomic effects，the current shortcomings in the utilization of elemental sulfur sources and sulphate were elucidated，while also introducing the latest advancements in sulfur source addition. The sulfur addition process within sulfur-containing ammonium phosphate was expounded through two techniques:sulfur coated and uniform distribution of sulfur sources. Application outcomes of products created by these techniques were compared，and the application scenarios of these products were analyzed. A concise analysis of the current development status of sulfur-containing ammonium phosphate products in China was provided，summarizing the existing challenges in their development. Finally，a prospective outlook on the future development of sulfur-containing ammonium phosphate in China was presented.
