摘　　要：为了研究土壤修复剂对淋洗尾土土壤功能的恢复效果,通过盆栽试验,分析了在添加土壤修复剂后淋洗尾土中种植甜高粱的生长状况,以及土壤pH值、EC值、容重、持水孔隙度、有机质含量、微生物群落结构、多样性等指标的变化。结果表明:与淋洗尾土处理相比,添加土壤修复剂后土壤的pH值、容重下降,EC值、持水孔隙度、有机质含量则增加,土壤微生物多样性增加,其中以添加5%土壤修复剂后甜高粱的生长状况最好,土壤微生物多样性相对较好。综合来看,添加5%土壤修复剂能够恢复淋洗尾土的土壤功能,促进了甜高粱的生长,能满足甜高粱苗期生长的需求。To investigate the impact of soil remediation agents on the functional rejuvenation of washed tail soil,a pot experiment was conducted.This study aimed to assess the growth condition of sweet sorghum planted in washed tail soil supplemented with soil remediation agents.Additionally,the experiment monitored changes in soil organic matter pH value,EC value,bulk density,water holding porosity,as well as the microbial community structure and diversity.The results showed that in comparison to the untreated leaching tail soil group,pH value and bulk density of the soil decreased upon the addition of soil remediation agents.Conversely,the EC value,water holding porosity and organic matter content and soil microbial diversity increased.Sweet sorghum growth was optimal when 5%soil remediation agent was added,soil and microbial diversity was relatively good.In conclusion,incorporating 5%soil remediation agent can restore the functionality of washed tail soil,enhance the growth of sweet sorghum,and cater to the growth requirements of sweet sorghum at the seedling stage.
