摘要：采用室内盆栽试验,以不添加钝化材料为对照,研究了海泡石、凹凸棒土、膨润土以及与磷酸二氢钾复配对土壤Cd钝化效果和小麦Cd吸收的影响。结果表明,不同处理均能提高土壤pH,显著降低土壤有效态Cd含量,显著降低小麦地上部和根部Cd的积累,以2%海泡石+0.04%磷酸二氢钾复配处理的降Cd水平最佳,可使土壤中有效态Cd含量降低16.16%,相应小麦地上部Cd和根部Cd含量分别降低42.31%和47.55%。
Pot experiments was conducted to evaluate the effects of application sepiolite,attapulgite,bentonite and their compound treatments with potassium dihydrogen phosphate on soil pH,soil Cd availability and Cd uptake of wheat.The results show that different treatments could increase soil pH,significantly decrease the contents of soil available Cd,significantly reduce the Cd content in wheat shoot and root.The deactivation capability of the passivator which were prepared from 2%sepiolite combined with 0.04%potassium dihydrogen phosphate had the strongest passivation abilities for Cd.
