Abstract: A pot experiment was carried out using calendula and pakchoi as experimental materials to study the effects of flower-vegetable intercropping on vegetable growth and heavy metal accumulation,in order to provide reference for the safe utilization of medium to light heavy metal polluted farmland.The results showed that compared with monoculture,neither intercropping nor cadmium treatment had significant effects on the morphology,photosynthetic physiology and physicochemical property of rhizosphere soil of both pakchoi and calendula in intercropping system.However,the cadmium uptake and enrichment of pakchoi decreased significantly in the intercropping system,while that of calendula increased significantly.Compared with monoculture,cadmium enrichment in shoot of calendula increased by 67.3%,while that of pakchoi decreased by 33.3% in intercropping system.Under the condition of intercropping,the cadmium content in rhizosphere soil of calendula was higher than that of monoculture,conversely,that in rhizosphere soil of pakchoi was lower,and the difference reached significant level.The ability of calendula to absorb for cadmium was higher than that of pakchoi,which might be the main reason for the change of cadmium uptake and distribution in the intercropping system.In summary,cadmium uptake and accumulation of pakchoi could be significantly lowered in the calendula and pakchoi intercropping system,so that the environmental risks could be reduced in the safe utilization of moderate cadmium polluted cultivated land through vegetable and flower intercropping.
