摘要
用Feddes模型模拟了地下排水和渗灌条件下麦田表层土壤的水分动态变化过程 .结果表明 :该模型能敏感地预测渗灌和排降后农田表层土壤的水分动态 。
Numerical simulation of surface soil moisture status in winter wheat fields under subdrainage and seepage irrigation is conducted based on the Feddes model.The results show that the model could predict surface soil moisture dynamic fluctuation in the fields after seepage irrigation and subdrainage.Soil moisture of root accumulating layers obtained by the model could be used to guide irrigation and subdrainage for winter wheats in the North Huai River area of Jiangsu province.
