| Abstract: |
| 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. |
