摘  要:
农田氮素流失是水环境氮素污染的主要来源,农田排水是造成农田土壤养分流失的主要途径。利用DRAINMOD排水管理模型通过对试验区排水量的模拟,确定了氮素流失量,氮肥淋失量与农田排水条件的关系,暗管排水强度增大,会增加氮肥淋失量,提出了进行合理水位管理,减少氮素流失的方法。

摘  要:
The nitrogen outflow is the important source of the water environment nitrogen pollution.The agricultural drainage is the main way of the farmland soil nutrient outflow.In this paper DRAINMOD drainage management model was used to simulate the displacement of test area.The relations between nitrogen outflow quantity,the nitrogenous fertilizer leaching out quantity and the agricultural drainage conditions were determined.The result show that the under-drainage intensity increases,the nitrogenous fertilizer leaching out quantity would increase.It is proposed that a reasonable level management will reduce the nitrogen outflow.
