| 摘 要： | 在查明土壤中硒酸盐还原作用与硝酸盐脱氮化作用的相关关系，在不同类型土－水系统中，加入一定量的ＫＮＯ３和ＮａＳｅＯ４溶液，观察ＮＯ＾－３和ＳｅＯ＾２－４的化学形态转变过程。实验结果表明，硒酸盐的还原作用和硝酸盐的脱氮化作用在时空变化上具有一致性。

| Abstract: | n order to investigate the correlation between selenate reduction and nitrate denitrification,a series of related experiments were carried out in different soil-water systems,in which a given amounts of KNO3 and Na2SeO4 solution were added,and the transformation processes of chemical speciation of selenate and nitrate were studied.The results indicated that the processes of selenate reduction and nitrate denitrification are identical in temporal and spatial changes, and the transformation of their chemical speciation relates not only to a kind of organic carbon compounds and temperature, but also closely to action of nitrate reductase. |
