Abstract:

To study the mitigation mechanism of cadmium (Cd) accumulation in rice by different foliar fertilizers, and provide evidences for resolving heavy metals pollution in agricultural field and food safety problem, the authors concluded the adverse effects of Cd on rice growth, rice leaves and the characteristics of foliar fertilizers including rice plant uptake nutrients through leaves, species and characters of foliar fertilizers, and the mitigating mechanisms of Cd accumulation in rice by foliar fertilizers. The authors also pointed out the effect factors that foliar fertilizers mitigating cadmium accumulation in rice, such as climate, temperature, utilization rate, spray times and concentrations. At last, the prospects were put forward, including combining with other mitigating ways, studying the other species of foliar fertilizer, keeping on the basic research of foliar fertilizer theory, strengthening the unified management and normative manipulation techniques.

Key words: foliar fertilizer, rice, cadmium, rice leaves, mitigate, nutrient uptake
