Abstract:

In Liuyang Qibaoshan mining area Hu’nan Province, Heavy metal pollution in soil, Mulberry variety ‘Lake MulberryⅠ’ was used as materials to determine the content of the four kind of heavy metal Cu and Pb and Cd, Zn in the soil and plant, to have a new understanding of the enrichment characteristics and the ability of four heavy metal in the mining area, and to predict the expected years of repairing to normal in mining area soil after contaminated. The results showed that each part of the mulberry trees the content of Cu in unit dry weight content of the root (33.13 mg/kg)>leaf (13.38 mg/kg)>skin (7.51 mg/kg)>bone (4.93 mg/kg), the content of Pb of the root (33.13 mg/kg)>leaf (10.32 mg/kg)>skin (3.35 mg/kg)>bone (1.73 mg/kg), the content of Cd of the root (4.53 mg/kg)>leaf (1.90 mg/kg)>skin (1.57 mg/kg)>bone (1.03 mg/kg), the content of Zn of the root (317.72 mg/kg)>leaf (186.53 mg/kg)>skin (105.07 mg/kg)>bone (89.16 mg/kg). The amount of heavy metals transferred from Tillage layer soil per square by mulberry, Cu 12116.1 mg, Pb 7409.83 mg, Cd 2056.4 mg, Zn 254532.8 mg.
