摘要:
以室内原状土柱进行的人工模拟降雨和人工控制淹水实验为基础,间接研究硝态氮在土壤中的存储结构,以及在模拟排水情况下,该存储结构对硝态氮运移通量的影响.结果表明,土壤结构和含水率决定了硝态氮在大小孔隙中的分配比例,在不考虑大孔隙硝态氮的影响下,硝态氮运移通量跟单位面积总水量成幂函数关系.该结论可为土壤质量评价和环境保护研究,提供实验研究参考和理论依据.
Abstract:
According to intact soil incubation,combined with the theory of the transformation of nitrogen in soil,the distribution of nitrate nitrogen in the soil was studied based on the experiments under the simulated rainfall and water-level-controlled conditions and its effect on the flux of nitrate nitrogen under water-level-controlled conditions was also investigated.The results obtained are summarized as follows: the proportion of the nitrate nitrogen stored in the large holes and small pores depends on the structure of the soil and the water content.If taking no account of the influence of the nitrate nitrogen in large holes,the flux of nitrate nitrogen tends to vary with the water quantity,presenting exponential curve.This theory can provide some experiment gist and theoretical guide to research for soil quality estimation and environmental protection.
