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pH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.
Abstract
[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 saline-alkali land in Linhe area.
