Inoculating rhizobia enhanced the dissolution and desorption of zn in cinnamon soil. the dissolution of zn are 10 % higher in cinnamon soil inoculated with rhizobia than non - inoculated and spe - zn, mno - zn and o. m - zn decreased by 9. 2 - 26. 0 % in the presence of rhizobia. the comprison of inoculating with non - inoculating rhizobia showed no evident distinction in total zn, but inoculating rhizobia decreased spe - zn and mno - znand increased exc - zn in red soil

瘤菌對褐土中zn的溶解和解吸使固定態zn減少66mg kg ,達10 ,專性吸附態、氧化
錳結合態和有機結合態zn減少達9 . 2 26 . 0 ,而紅壤zn的總量變化不顯著,但是專性吸附態和氧化
錳結合態zn含量顯著減少,可交換態zn含量顯著增加。
Added rhizobia increased the amount of negative charge and metallo - ion specific adsorbing sites of solid compositions such as mn oxides and organic matter etc. the influences of adsorbing rhizobia by soil on the speciation of heavy metal varied with the metal and the soil and were closely related to the mechanisms of metal fixation by soils
土壤吸附根瘤菌后負電荷量增加,某些組分如氧化錳和有機質等吸附重金屬的專性吸附位點有所增加。土壤吸附根瘤菌對土壤中重金屬的形態影響隨重金屬種類和土壤類型而不同,與重金屬在土壤中的吸持機制有直接關系,當重金屬以沉澱機制為主被土壤吸持時,其形態分佈受根瘤菌的影響不顯著。
