Abstract: The soil culture experiments were performed to study the difference of Cadmium uptake and accumulation among 4 different Chinese cabbages cultivars.The relationship between shoot Cd concentration of four Chinese cabbages cultivars and soil Cd concentration could be simulated by mathematic model.Positive linear correlation and quadratic curve were found between both.Test results suggested that correlation of both relationship attained significant level.According to the provisions of leafy vegetables the maximum allowable limit of Cd standard of 0.2 mg/kg in the GB2762-2005,maximum soil Cd concentration for Xinbeijing3 hao,Beijingxiaoza 60,Duokang 3 hao and Zaoxinbai were 1.74,2.25,0.603 and 0.842 mg/kg significantly.The soil Cd concentration of 1.0 mg/kg were the important control indicator for the vegetable food security.
