It appeared that no observable difference in the cu forms bewteen inoculating and non - inoculating rhizobia in red soil . inoculating rhizobia did n ' t enhance or inhibited the dissolution and desorption of cd in two soils , but changed the order of cd speciations in red soil 接種根瘤菌對土壤中cd的溶解和解吸沒有明顯地抑制或促進，但改變了紅壤各形態cd的含量大小順序， cd污染紅壤中可交換態和有機結合態cd含量分別增加22 、 11 。
