摘　　要：[目的]研究盐碱地施用磷石膏对土壤理化性质和向日葵产量的影响,以期为临河区盐碱地改良研究提供理论支持。[方法]以磷石膏为改良剂,研究盐碱地施磷石膏后土壤理化性质和向日葵产量的变化。[结果]磷石膏可促进盐碱地土壤耕层脱盐,降低土壤p H和交换性钠含量,增加向日葵盘数、盘粒重和产量。[结论]以磷石膏作为盐碱地土壤改良剂适合在临河区应用和推广。[ Objective] To study the effect of phosphogypsum on the physical and chemical properties of soil and the yield of sunflower, in order to provide theoretical support for the research of saline-alkali improvment in Linhe area. [ Method] Using phosphogypsum as the research material,the change of the physical and chemical properties of soil and the yield of sunflower after applying phosphogypsum in saline-alkali land was studied. [Result] Phosphogypsum could reduce the soil total salt content,pH and soil exchangeable sodium content,and increase the number of sunflower dish, weight per dish and yield. [ Conclusion ] Phosphogypsum is suitable for application and promotion as modifier of sa- line-alkali land in Linhe area.
