摘　　要：利用蘑菇废料作为稳定剂,通过水稻盆栽试验,采集不同时期土壤和植株样本,监测土壤及植株中的镉含量及土壤理化性质,评估修复效果,并探析可能的机理。结果发现,蘑菇废料施用可以使土壤中有效态镉含量下降64.0%以上,植株中镉含量下降27.9%,糙米中镉含量下降17.7%,表明具有较好的镉修复作用;同时,蘑菇废料施用使土壤有机质含量提高了30.0%以上,水稻产量提高32.9%,表明具有提高土壤生产力的作用。Using mushroom waste as stabilizer,through pot experiment of rice,soil and plant samples were collected,cadmium content and soil physical and chemical properties in soil and plant were monitored,remediation effect was evaluated,and possible mechanism was explored.The results showed that the application of mushroom waste could decrease the content of available cadmium in soil by more than 64.0%,the content of cadmium in plant by 27.9%,and the content of cadmium in brown rice by 17.7%,which indicated that mushroom waste application could increase the content of soil organic matter by more than 30.0%and the yield of rice by 32.9%,indicating that the application of mushroom waste could increase the productivity of soil.
