摘要
本文以田间试验资料为基础，综合考虑了气象、作物和土壤因素对农田实际蒸散的影响，采用Ｐｒｉｅｓｔｌｅｙ－Ｔａｙｌｏｒ公式，并且结合叶面积指数和相对有效土壤湿度建立了冬小麦农田实际蒸散计算模型．该模型仅需常规气象资料和农业气象资料，计算简便，具有一定的应用价值．
In the paper,based on the measured data in the field,comprehensively considering over the meteorological condition,crop and soil state,we established the calculation model for actual evapotranspiration of winter wheat field with the Priestley--Taylor formula,leaf index and relative effective soil moisture.The model is convenient to calculation,using routine meteorological and agrometeorological data only. It is of value in utilization.
