- Abstract
In this study, a field experiment was conducted in the calcareous soil with slight cadmium (Cd) pollution to screen out the suitable foliar inhibitor with good Cd reduction effect and provide references for the safe production of wheat in Cd slightly polluted soils. Three self-made foliar inhibitors (ZP1, ZP2, ZP3) were spayed at jointing stage, heading stage and filling stage as treatments, foliar spraying of dilluted water was used as the control (CK), and the effect of these treatments on Cd translocation and bioconcentration of wheat was examined. The results showed that compared with CK, spraying ZP1, ZP2 and ZP3 had no significant effect on wheat yield and quality, yet significantly reduced Cd translocation factor from stem to leaves and Cd bioconcentration factor in leaves, and significantly increased the contents of Cu and Zn in wheat leaves. Besides, foliar spraying of ZP3 significantly reduced Cd content in wheat grains by 43.3%. Therefore, for calcareous wheat fields with slight cadmium pollution, ZP3 was recommended to safeguard the production of wheat.
