| Abstract: |
| Cadmium pollution in vegetables has become a serious problem which can result in vegetable quality
loss and endanger human health damage. The effects of soil conditioner on the absorption of cadmium in different
vegetables（including fruit vegetables，leaf vegetables and root vegetables）were studied at different application
levels. The results showed that soil conditioner had different effects on cadmium uptake by different vegetables. The
content of Cd in soybean，soybean，ginger，mustard blue and melon were significantly reduced by 47.13%. And
the content of Cd in leaf lettuce were reduced by 16.4% on average，and there is no obvious effect on cucumber and
pepper. Before adding the soil conditioner，the content of cadmium in cucumber and green bean were low which can
meet the national standard. All fruit vegetables（ except chilies） grown on caolmium polluted soil with 300 kg/667
m2 soil conditioner can meet the national standard，which suggested that fruit vegetables were suitable plants for
cadmium contaminated land. |
