A field experiment was conducted with rape plants to assess the impacts of integrated fertilization on heavy metal balance in soil-rape cropping system.Four treatments as chemical fertilizers(T1),chemical fertilizers lower rate of organic manure(T2),chemical fertilizers medium rate of organic manure (T3),and chemical fertilizers high rate of organic manure(T4) were designed in the present experiment.The doses of N,P_2O_5,and K_2O of each treatment were equal,and each treatment had four replications.The results indicated that high rate of organic manure could significantly reduce shoot biomass and grain yield of rape plants.It was found that zinc and copper deficits occur in the treatments with no organic manure or lower rate of organic manure,and cadmium accumulation occur in the treatment with high rate of organic manure.Integrated fertilization with appropriate rate of organic manure and chemical fertilizers could not only remain the balance of zinc and copper as micronutrients,but also minimize the risk of cadmium pollution in the cropping system,which can be regarded as an effective manner for the construction of sustainable agriculture.
