摘要:

为探究不同叶面肥阻控水稻富集镉的机制,以期为解决农田重金属镉污染和食品安全问题提供科学的依据。本研究归纳了镉对水稻的生长危害,水稻叶与叶面肥的特征包括水稻叶与水稻的养分吸收、叶面肥的种类、叶面肥的特点及叶面肥阻控水稻富集镉的机理。指出影响叶面肥阻控水稻富集镉的效果因素,如天气、温度、利用率、喷施次数和浓度等,提出与其他阻控措施相结合、开展其他种类叶面肥研究、继续叶面肥理论基础研究及加强统一管理和规范操作技术等一系列展望。

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
