摘要：The area of Cd-contaminated wheat farmland is large worldwide, to achieve safe wheat production in Cd-contaminated farmland, it is necessary to take cost-effective measures to mitigate the Cd accumulation in wheat plants. A pot experiment was conducted in this study to evaluate the effectiveness of sepiolite and potassium dihydrogen phosphate (KDP) as soil amendment, in combination with different leaf barriers, for mitigating Cd translocation and accumulation in wheat plants grown in farmland soil contaminated with Cd. The application of soil amendment either alone or in conjunction with foliage supplementation of Si, Ca or Zn significantly reduced soil DTPA-extractable Cd by 27.97%-34.58% and grain Cd concentration by 18.69%-43.61% respectively. Exogenous Si/Ca/Zn spray had an additive effect in reducing Cd in wheat grain grown on sepiolite + KDP treated soil, with increased dosages of foliar barriers resulting in decreased grain Cd concentrations. The lowest concentration of Cd (0.60 mg center dot kg-1) in wheat grain was observed with foliar spraying a higher dosage of Si and soil application of sepiolite + KDP treatment (ASi-H). These results suggest that soil application of sepiolite + KDP combined with foliar application of Si/Ca/Zn, especially Si, could be an efficient and low-cost method for remediating Cd-contaminated alkaline soils.
