Chemical behavior of heavy metals in rhizosphere——Ⅱ. The rhizosphere effect of desorption of adsorbed Cu in soils.

Wang Jianlin and Liu Zhiyu(Institute of Soil Science, Academia Sinica,Nanjing 210008).  
In this paper, the rhizosphere effect of desorption of adsorbed Cu previously in the Quaternary reddic paddy soil (QP), Lateritic red soil(LR), Quaternary red earth (QR) and White bleaching paddy soil(WP) were investigated. The results showed that the adsorbed Cu could be divided into the easily desorped Cu (Cuedes), which could be desorped by 0.1M KNO_3, and the difficultly desorped Cu (Cuddes), which would be desorped by 0.1M HCl. As the adsorption of Cu increased, the desorption percentage of Cuedes increased, while that of Cuddes decreased. For Cuedes, it was less in rhizosphere soil than in bulk soil, the rhizosphere effect of samples was shown as QPWPLRQR, and the mean desorption percentage of easily desorped Cu were in the order of QPWPLRQR. For Cuddes, it was much in the rhizosphere soil, the rhizosphere effect was shown as WPLRQPQR, and the mean desorption percentage of difficultly desorped Cu were in the order of QPWPLRQR. The total desorption percentage of samples were QPWPQRLR. The increase of Cu adsorption in rhizosphere was mainly attributed to the increase of difficultly desorped Cu.
