| description | The dynamics of transportation, accumulation, disappearance and distribution of <sup>95</sup>Zr in the broadbean- soil system was studied by isotope-tracer technique, and the fitting equation was established by application of the closed two-compartment model and nonlinear regression method. The results showed: ①<sup>95</sup>Zr was transported in the system shortly after its addition into the surface layer of soil. <sup>95</sup>Zr was absorbed mainly via root of broadbean and then redistributed among all parts of the broadbean plant. The concentration of <sup>95</sup>Zr in the whole plant reached a maximum value, which was followed by a steady decrease. The concentration of <sup>95</sup>Zr in root was much higher than in other parts of the plant. The concentrations of <sup>95</sup>Zr in different parts of broadbean plant arranged in order was root > straw > husk > seed. ②Most of <sup>95</sup>Zr detained in 6cm upon layer of the soil, and its concentration was single term exponential negative relation with depth of soil. ③The dynamics of <sup>95</sup>Zr in broadbean-soil system could be described using multinomial exponential. ④Broadbean plant has the ability of enriching with <sup>95</sup>Zr from soil to some extend. |
