Thus, only with conventional meteorological variables, soil temperature, soil hydrological parameters and crop growth stage fed into the model, can prediction be satisfactorily performed of soil water regime in winter wheatfields, with the maximum relative error averaging within 8%. 模型只需输入气象变量、土壤温度、土壤水文学参量及作物发育期等常规资料,即可对冬小麦田土壤水分状况进行预报,预报值与实测值的平均最大相对误差在8%以内。
