Based on the meteorological data, the evapotranspiration of wheat has been estimated by using FAO-17 Penman revised equation and Penman-Monteith equation method respectively in Xinxiang, Henan province.
利用FAO-17Penman修正公式及Penman Monteith公式对豫北地区冬小麦的蒸腾蒸发量进行了计算,并与试验实测结果进行对比分析,结果表明:由于两种方法选用了不同的空气动力学项和辐射项公式,造成计算结果有一定的差异,但从整个小麦生育期来看,这两种方法总体上误差不超过10%;两种方法对豫北地区冬小麦的蒸散量的计算结果,其总体变化趋势与实际较吻合,在各生育期内,绝对误差不超过18mm,全生育期不超过40mm,估计相对误差在10%内,两种方法比较,Penman Monteith公式更适合当地情况。
