从分析中国大米镉污染的严峻程度和地域分布现状着手,综述采用生物技术及杂交技术和基因工程技术改变水稻的性状进而降低大米中镉的富集,微生物吸附和发酵等技术降低大米镉含量的方法;还从农作技术方面介绍添加不同肥料以降低土壤镉含量的方法。指出利用基因工程直接进行转基因和靶基因的敲除与敲低的方法虽然精准高效,但在食品安全方面尚存在争议。而通过筛选低镉富集品种,杂交技术和微生物转化镉大米则为防治大米镉污染提供了有效的生物技术途径,在土壤中添加不同的肥料降低土壤镉含量的方法的农作技术,对于当前的农业生产来说是成本低且行之有效的方法。

In this paper,on account of the current situation that some rice have high cadmium content or even exceeds the national standard,the severity and regional distribution currently at home and abroad are analyzed.The necessity of controlling cadmium pollution of rice was revealed,and the methods of biotechnology and farming at home and abroad were systematically integrated,such as screening low cadmium enriched rice varieties using biological technology,hybrid technology and genetic engineering technology that includes transgene technology,gene knockout and gene silencing to improve rice traits.T...
