| 摘 要： | 重金属镉是农田土壤污染最为突出的元素之一,对农产品安全生产造成严重影响。由于镉的生物有效性决定了植物根部对镉的吸收,所以土壤镉生物有效性调控技术是近年来农业资源利用领域的研究热点。文章综合评述了镉污染农田安全利用技术,并分别通过低镉累积作物、原位钝化技术、叶面阻控技术以及农艺调控技术来介绍镉污染农田土壤的安全利用方法,针对各种修复技术的特点,提出镉污染农田土壤修复技术的研究和发展方向,为镉污染农田安全利用技术研究提供参考。

| Abstract: | Heavy metal cadmium is one of the most prominent elements in farmland soil pollution, which has a serious impact on the safe production of agricultural products. Because the bioavailability of cadmium determines the absorption of cadmium by plant roots, the regulation technology of soil cadmium bioavailability is a research hotspot in the field of agricultural resource utilization in recent years. This paper comprehensively reviews the safe utilization technology of Cadmium Contaminated Farmland, and introduces the safe utilization methods of Cadmium Contaminated Farmland soil through low cadmium accumulation crops, in-situ passivation technology, leaf resistance control technology and agronomic regulation technology. According to the characteristics of various remediation technologies, this paper puts forward the research and development direction of cadmium contaminated farmland soil remediation technology, so as to provide reference for the research of Cadmium Contaminated Farmland safe utilization technology. |
