A pot experiment was conducted to evaluate the effect of intercropping with different herbaceous plants on the uptake and transfer of Cd by water spinach as well as the remediation efficiency of Cd polluted soil. In this study, ten different herbaceous cultivars i.e. Gaodan grass, Sultan grass, Pennisetum, Ryegrass, Bitter vegetables, Chicory, Grain amaranth, Alfalfa, Clover and Vetch were used as intercropping plants, Cd accumulation by water spinach and remediation efficiency were mainly evaluated by the removal rate (%) of Cd in edible part (shoots) of water spinach and removal rate (%) of Cd from polluted soil. The results showed that significant differences (P<0.05) of shoot and root Cd content of water spinach were observed between the intercropping treatments. Among the treatments, the shoot Cd content was significantly decreased by Gaodan grass, Sultan grass and Pennisetum intercropping, the Cd decrease rate (%) reached 34.0%, 35.8% and 34.3% respectively, however, the uptake of Cd by water spinach was promoted with intercropping with Chicory, Grain amaranth, Alfalfa, Clover and Vetch resulting in increased shoot Cd content. Significant difference of the uptake and transfer of Cd by herbs was also observed in this study, the shoot Cd for herbs ranged from 1.81mg/kg to 12.87mg/kg, with a maximum variation of 7.1folds, the shoot Cd content of the tested herbs followed the order of Bitter vegetables > Chicory > Sultan grass≈Ryegrass > Gaodan grass ≈Pennisetum > Clover ≈ Grain amaranth > Alfalfa ≈ Vetch. The removal rate (%) of Cd from the soil ranged from 0.35% to 1.49% among the treatments. The removal rate (%) of Cd from the soil for the intercropping with Gaodan grass, Sultan grass, Pennisetum reached 1.46%, 1.49% and 1.48% respectively. Intercropping with Gaodan grass, Sultan grass, Pennisetum can not only effectively reduce the Cd uptake by water spinach, but also remove Cd from polluted soil with high efficiency. In conclusion, Gaodan grass, Sultan grass and Pennisetum have great potential application for the intercropping treatment for remediation of Cd polluted field soils.
