基于石膏尾矿的盐碱地复合调理剂应用及经济性评估

Application and Economic Evaluation of A New Composite Amendment for Saline-alkali Soil Based on Gypsum Tailings and Fullerene

研发了一种以石膏尾矿、富勒烯等为核心原材料的新型石膏基盐碱地复合调理剂,以解决脱硫石膏中存在的重金属安全隐患,并对石膏尾矿进行资源化再利用。通过在内蒙古苏打盐碱地上的应用结果表明,该调理剂可以显著提高水稻的产值和净收益,同时有效改善土壤理化性质,促进土壤养分平衡的建立。通过成本效益分析表明,该调理剂的投产比为1.8,具有较高的应用价值和推广前景。

In view of the safety hazards of heavy metals associated with desulfurization gypsum,developed a new fullerene-based compound conditioner for saline-alkali soil using gypsum tailings.The experiment conducted in soda-saline soil in Inner Mongolia showed that the conditioner can effectively improve the soil structure and fertility of the soda-saline soil,significantly increasing the yield and net income of rice planting.Cost-benefit analysis showed that the benefit-cost ratio of the conditioner was 1.8,indicating its high application value and potential for promotion.
