摘　　要：以不同基因型的普通白菜为试材,研究盆栽和池栽两种栽培方式下土壤中Cd浓度对普通白菜Cd累积的影响。结果表明:两种栽培模式下普通白菜的Cd累积量均随着土壤Cd浓度的增加而增加,但品种间差异明显;盆栽普通白菜的Cd累积量总体上高于池栽,在土壤Cd浓度为1.08 mg·kg^(-1)时盆栽普通白菜Cd累积量均值为115.08μg·kg^(-1),而池栽仅为64.57μg·kg^(-1)。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.
