摘要
根据灌区所处的地理位置、气象水文及土壤特征 ,选用了适宜的计算参数 ,采用彭曼公式和土壤水分运移模型 ,模拟计算了不同作物生育期的耗水量和土壤含水率 ,其结果理论计算值与实测值基本一致 。
According to geographic position, atmosphere, hydrology and soil agricultural division property at the Beitun irrigation region suitable calculated parameter has been choosed.Boman formula and movement model of soil water, water sumption and soil water content of different crops had been applied.As a result,theory calculating value and measured value are on the whole identical.Irrigation procedure formulated through reducing expenditure irrigation test is feasible at the Beitun irragation vigion.
