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
在室外進行了不同清污水灌水量與施肥條件下氮素遷移轉化試驗，同時進行了考慮根系吸收，硝化和反硝化的田間非飽和no _ 3 ~ - ? n遷移轉化模型的數值模擬，研究結果表明與施肥相比，污水灌溉對土壤中no _ 3 ~ - ? n累積的貢獻較小，所建立模型可用於模擬no _ 3 ~ - ? n在土壤中的遷移。 -
