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。
In this paper, the effects of applying potassium chloride (KCl) on Cd uptake and accumulation in rice and wheat at different growth stages were studied in cadmium contaminated soil. The results showed that KCl could promote the uptake of cadmium by both crops. KCl promoted cadmium uptake by rice more efficiently than cadmium.
