| Abstract: |
| The contents of soil heavy metal in Xi'an area were investigated. The typical cultivated field soil profile and the typical greenhouse soil profile were chosen as the research objects and collected samples of soil. The total con-tents of As, Cr, Cu, Pb, Zn and Ni in soil samples collected from the area were analyzed. The results shown that the
contents of Cr, Cu, Pb, Zn and Ni in the profile of field cultivated soil in 0~20 cm was were higher than that of in the
greenhouse soil, over53.1, 16.7, 20.5, 151.2 and 3 mg/kg respectively. The greenhouse were more beneficial the
heavy metals' transfer in horizon. It is obvious that the migration conversion degree to the soil heavy metals such as Zn, Cr, Cu and Pb. This paper reckons putting forward to develop the greenhouse flowers cultivation to control soil heavy metals pollution maybe is a profitable way for sustainable development of agriculture in the future. |
