添加脱硫石膏对盐碱土壤入渗性能及土壤性质的影响

已有的科学研究和生产实践证明，添加脱硫石膏可以有效改良东北苏打盐碱土。但通过添加脱硫石膏如何影响土壤水分入渗性能及盐碱土性质的相关研究还比较缺乏。本文通过室内土柱淋洗试验，明确了土壤入渗效率随脱硫石膏用量的增加而增加，能够有效降低盐碱土的pH、EC、碱化度等，为盐碱土壤的改良修复提供了理论依据。

Effect of Desulfurization Gypsum Addition on Soil Infiltration and Properties of Saline Alkali Soil

The application of desulfurization gypsum has been proven effective in improving soda saline alkali soil in Northeast China. However, the influence of desulfurization gypsum addition on soil water infiltration performance and the properties of saline alkali soil remains understudied. This research conducted indoor soil column leaching tests to investigate the impact. The results revealed that the soil infiltration efficiency increased with higher amounts of desulfurization gypsum, effectively reduced the pH, EC (electrical conductivity), ESP (exchangeable sodium percentage), and other relevant parameters of saline alkali soil. This study provides a theoretical foundation for the enhancement and remediation of saline alkali soil.
