烟草对重金属的吸收分布特征及影响因素研究综述

摘要

The concentrations of heavy metals in agricultural soils have become increasingly high since the 20th century in China. With the heavy metal contamination, tobacco as an important economic crop, the growth was retarded and the yield and quality was lost. This paper reviewed research advances of contents, absorption, distribution and its influencing factors of heavy metals in tobacco, and offered suggestions for future research.%20世纪以来,重金属在生态环境中得到快速积累,烟草作为一种重要的经济作物,重金属污染使烟草生长发育受阻,产量和品质下降.综述了烟草有关重金属的含量、吸收特点、分布特征及其影响因素方面的研究进展,并展望了今后的研究方向.
