Research on Effect of Fe on the Transportation and Transition of Nitrogen in Farmland Soil
Author(s): 
Pages: 60-64
Year: Issue:  12
Journal: Environmental Science and Management

Keyword:  农田土氮转化;
Abstract: 以长春伊通河河谷阶地上部的农田土为研究对象,选用铁离子作为氮转化的一种影响因素,定性研究了不同浓度的铁离子对硝态氮、亚硝态氮、铵态氮三氮的变化影响.并且在建立方程组之后计算平衡常数,证明了铁的氧化作用,与实验所得相符合:铁促进铵态氮的吸附、促进硝化反应的进行.从实验和理论的角度说明了铁在三氮转化中起的作用,为进一步研究锰铁离子对氮转化的定量影响和氮素污染地下水的预测和定量评价提供科学依据.
