不同灌水方式下依据水面蒸发量确定夏玉米适宜灌溉制度的研究
发布时间:2022-02-21 21:05
田间试验于2011和2012年的6月-9月在位于河南省新乡市的中国农业科学院农田灌溉研究所进行。本文的研究目标是探寻三种灌水方式下、以E601水面蒸发量为基础制定夏玉米的最佳灌溉制度。试验在防雨棚下测坑中进行,3种灌水方式为畦灌(B)、沟灌(F)和滴灌(D)。每个灌溉方法设置三个灌溉定额,由蒸发皿蒸发量和蒸发皿系数确定。试验共9个处理,重复3次,在27个测坑中实施。三种灌溉方法下设定的灌溉模式为:畦灌(B):0.75*PE,1.0*PE和1.25*PE;沟灌(F):0.75*PE,1.0*PE和1.25*PE;滴灌(D):0.67*PE,0.3*PE和1.5*PE。试验结果表明,三种灌水方式下夏玉米的耗水量主要受灌溉制度的影响。地面灌溉(B)的总耗水量略高于沟灌(F),也高于滴灌(D)。试验结果同时表明,2011和2012年蒸散量(ET)最大的处理为B3(406.6mm和323.1mm),2011和2012年ET值最小的处理分别为D1(231.4mm)和D2(174.3mm)。滴灌下的日均ET值要低于畦灌和沟灌。灌水方式对叶面积指数和株高有较大的影响。2012年B1处理的产量(1023...
