田間試驗于2011和2012年的6月-9月在位于河南省新鄉(xiāng)市的中國農業(yè)科學院農田灌溉研究所進行。本文的研究目標是探尋三種灌水方式下、以E601水面蒸發(fā)量為基礎制定夏玉米的最佳灌溉制度。試驗在防雨棚下測坑中進行,3種灌水方式為畦灌（B）、溝灌（F）和滴灌（D）。每個灌溉方法設置三個灌溉定額,由蒸發(fā)皿蒸發(fā)量和蒸發(fā)皿系數(shù)確定。試驗共9個處理,重復3次,在27個測坑中實施。三種灌溉方法下設定的灌溉模式為：畦灌（B）:0.75*PE,1.0*PE和1.25*PE；溝灌（F）：0.75*PE,1.0*PE和1.25*PE；滴灌（D）：0.67*PE,0.3*PE和1.5*PE。試驗結果表明,三種灌水方式下夏玉米的耗水量主要受灌溉制度的影響。地面灌溉（B）的總耗水量略高于溝灌（F）,也高于滴灌（D）。試驗結果同時表明,2011和2012年蒸散量（ET）最大的處理為B3（406.6mm和323.1mm）,2011和2012年ET值最小的處理分別為D1（231.4mm）和D2（174.3mm）。滴灌下的日均ET值要低于畦灌和溝灌。灌水方式對葉面積指數(shù)和株高有較大的影響。2012年B1處理的產量（1023...
