摘要
依据理论分析和田间实测资料，提出了玉米生长条件下农田土镶水分动态预报模型，论述了模型中参数的测取方法。经初步应用结果表明，该模型预报玉米地土壤水分动态具有较高的精度。
Based on the theoritical analysis and the measured data in corn-land, this paper pre-sents a model to forecast soil water dynamic process in corn-land. The model includes threebranch systems, they are soil water dynamic process in root zone of corn, dynamic process ofwater uptake by corn root, and dynamic process of evapotranspiration. The measuring and es-timating method of parameters in the model is also described. The result of application showsthat the forecast of soil water dynamics and evapotranspiration by using the model has highprecision.
