Abstract To investigate the differences of cadmium uptake and accumulation in vegetables under different planting patterns, field experiment was carried out with Cd contaminated soil in Daye, Hubei Province. It was shown that Cd contents and accumulations in edible parts of vegetables under the planting pattern of white turnip-tomato-green turnip were lower than those in vegetable under other planting patterns. In addition, the yields and economic benefits of white turnip-tomato-green turnip pattern were the highest of all the planting patterns. Meanwhile, Cd accumulation in non-edible parts of vegetables was higher than that under other planting patterns, except the planting pattern of white radish-cowpea-water spinach-flower Chinese cabbage. For all planting patterns, Cd concentrations were higher in leaf vegetables than that in cowpea, tomato and flower Chinese cabbage. According to the above results, the planting pattern white turnip-tomato-green turnip was recommended for Cd polluted soil, and cowpea, tomato and flower Chinese cabbage were the recommend vegetables.
