摘要
Abstract
To address the saline-alkali soil issues in Gansu Province,this study compared the effectiveness of three soil amendments:organic fertilizer,fly ash,and biochar.The experimental results demonstrated that all amendments significantly enhanced the physicochemical properties of saline-alkali soil.Fly ash showed optimal performance in soil organic matter content,increasing it by 50.2%compared to the control group.Organic fertilizer exhibited the best performance in enhancing total nitrogen content,achieving a 733.3%increase.While both organic fertilizer and biochar had minimal impact on total potassium content,fly ash reduced it by 18.2%.Organic fertilizer remarkably boosted available potassium content by 299.6%compared to the control.Both organic fertilizer and fly ash also demonstrated excellent effects in increasing total phosphorus and available phosphorus levels.The findings provide theoretical foundations and technical guidance for improving saline-alkali soil in Gansu Province.关键词
