摘　　要：本文研究在镉污染的土壤上施用钾肥（KCl）对水稻、小麦在不同生育期吸收累积镉的影响。结果表明：KCl对这两种作物吸收镉均有促进作用，KCl对水稻吸收镉的促进效率高于小麦，其可食部分含镉量是：麦粒＞糙米。Pot experiment was conducted to study the effect of potash fertilizer on Cd uptake and ac cumulation by rice and wheat. The results indicated that KCl stimulated the Cd uptake of rice and wheat grownllin the Cd-contaminated Soil. The stimulation of Cd uptake by KCl application varied with crops and growth stage. More stimulation was found in rice than that in wheat Cd content in wheat grains was qreater than rice.
