| 摘 要： | 采集了我国12个主要植烟省份2010—2011年期间使用的95个烟用肥料样品(其中有机肥样品28个、无机复混肥样品39个、磷肥样品13个、钾肥样品15个),测定了其重金属As、Cd、Cr、Hg和Pb的含量。结果表明:我国烟用肥料中重金属含量均低于相应的国家限量标准,无超标现象,其中Pb、Cr含量相对较高,Cd、As、Hg含量相对较低;磷肥中5类重金属含量都较高,无机复混肥中As、Cd、Pb含量较高,有机肥中Hg、Cr含量较高,钾肥中Cr和Cd含量较高;黄淮烟区的肥料重金属含量较高,尤其是Cd和Cr。

| Abstract: | It is of significant to know the contents of heavy metals in the fertilizers for tobacco sustainable production. We collected 95 samples of fertilizers used in 2010 and 2011 from 13 tobacco-planting provinces of China and analyzed the heavy metal contents of As, Cd, Cr, Hg and Pb in the fertilizers. The results showed that the contents of heavy metals in all of the tobacco fertilizers were lower than the national limits. In the tobacco fertilizers the contents of Pb and Cr were higher than those of Cd, As and Hg. The heavy metal contents were usual higher in phosphate fertilizers, As, Cr and Pb were higher in inorganic compound fertilizers, Hg and Cr were higher in organic fertilizers while Pb and Cd were higher in potassic fertilizers. The contents of Cd and Cr in tobacco fertilizers of Huang-huai tobacco-planting region were higher. |
