Taking pakchoi as test material，this paper studied the effect of soil Cd concentration in 2
cultivation modes including pot and pool on Cd accumulation of pakchoi．The results showed that under
these 2 cultivation modes，Cd accumulation quantity in pakchoi increased along with the increase of soil Cd
concentration．But，there existed obvious intervarietal differences．The total Cd accumulation quantities
in potted pakchoi were higher than that in pooled pakchoi．When soil Cd concentration was 1.08 mg·kg^-1，
the average Cd accumulation value of potted pakchoi was 115.08 μg·kg-1，that of pooled one was only
64.57 μg·kg^-1．
