摘　　要：以受Pb+Cd+Cu污染的农用地为研究对象,采用将羊粪有机堆肥与各类无机、有机钝化材料复合的策略,制备5种有机肥复合钝化剂,通过盆栽实验对比修复前后土壤理化性质、重金属赋存状态、植株(大蒜)生长状况及体内重金属富集情况等进行修复效果综合评价。结果表明,有机肥复合钝化剂钝化效果优于单一堆肥,其中羊粪堆肥与钙镁磷肥质量比5.0∶0.8制备的有机肥复合钝化剂对土壤中Pb+Cd+Cu复合钝化率最高,达到43.06%;对大蒜植物体内Pb、Cd、Cu修复指数分别为53.30%、53.60%、59.34%,Pb+Cd+Cu复合修复指数高达57.10%,且显著提高了土壤有机质和N、P含量,可用于农用地土壤Pb+Cd+Cu污染修复治理。Taking the agricultural land polluted by Pb+Cd+Cu as the research object,five kinds of organic fertilizer compound passivators are prepared by adopting the strategy of compounding sheep manure organic compost with various types of inorganic and organic passivation materials,and the physical and chemical properties of soil,the heavy metal storage status,plant(garlic)growth and heavy metal enrichment in the plant before and after remediation are compared to evaluate the comprehensive remediation effect.The results show that passivation effect of the organic fertilizer compound passivator is better than single compost,in which the organic fertilizer compound passivator prepared by sheep manure compost and calcium magnesium phosphate fertilizer with a mass ratio of 5.0:0.8 has the highest composite passivation rate of Pb+Cd+Cu,which is as high as 43.06%;The restoration indexes of Pb,Cd and Cu in garlic plants are 53.30%,53.60%and 59.34%,respectively,and the Pb+Cd+Cu composite restoration index is as high as 57.10%;And it significantly improves the soil organic matter,N and P content.The organic fertilizer compound passivator can be used for the remediation and treatment of the Pb+Cd+Cu pollution in agricultural land.
