短程硝化反硝化的研究
In field study , the expenment on nitrogen transport and transformation in soils with different irrigation ( with both ground water and sewage effluent ) and fertilization levels has been conducted . with considenng the n - uptake , nitrification and demtrification processes , a model for describing no2 - - n transport and transformation in unsaturated soil has been applied . results show that , the n03 + - n accumulating in soil is contributed more by fertilization but lees by irrigation with sewage effluent , and the model can be used to simulate no3 - - n transport in soils
在室外进行了不同清污水灌水量与施肥条件下氮素迁移转化试验，同时进行了考虑根系吸收，硝化和反硝化的田间非饱和no _ 3 ~ - ? n迁移转化模型的数值模拟，研究结果表明与施肥相比，污水灌溉对土壤中no _ 3 ~ - ? n累积的贡献较小，所建立模型可用于模拟no _ 3 ~ - ? n在土壤中的迁移。
