Abstract: The effect of defferent forms of N,P and K fertilizers on Cd uptake by Brassica chinensis and the defference betweenthe uptake and accumulation of Cd by the cultivars are studied with pot experiment.The results show that soil pH and conternts of soluble and exchangeable Cd are affected by different forms of chemical fertilizers.Cd content in shoots of five cultivars is in order of Chi-2≥Shijiu-19>Chi-29≥Teqing-80>Teping-60.Hydroponic culture experiment indicates that the uptake rate of Cd by unit root surface and its translocation rate to aboveground parts of Teping-60 are lower thant that of Chi-2.
