英文摘要 | The seasonal variation in physiological cycle (spring period, summer period, autumn and winter period)about the total contents of Cu, Zn, Pb and Cd around Scirpus mariqueter rhizospheric and nonrhizospheric sediment were researched. The results showed the root sediment behaved commonly by rhizosphere>nonrhizosphere except Zn in fruit period, Cu and Pb in seeding and fruit periods or Cd in three periods(growth, flower and fruit period).The chemical speciations of root sediment were ulteriorly analyzed. The results indicated that the chemical speciations of rhizosphere sediment were much different from those of nonrhizosphere in the whole physiological cycle. Moreover, Cu and Pb were found to be the trend of changing from the active form in nonrhizosphere sediment to the residuals in rhizosphere, which led to the bioavailability reduction. But Zn was found varying in the reversed direction, that means its bioavailability increased. And the trend of Cd was not obvious. |
