为高效利用自然降水和灌溉水,于2011—2012年在晋南小麦-玉米两熟制地区进行大田试验,研究了不同灌水（每次灌水450m^3/hm^2）、秸秆还田处理对冬小麦需水、耗水特性、水分利用效率及产量效应的影响。结果表明：不同灌水处理下土壤贮水量呈现W0〈W1〈W2〈W3;土壤耗水量表现为W0〉W1〉W2〉W3;总耗水量依次为W0〈W1〈W2〈W3;WUE呈现W2〉W3〉W1〉W0;产量表现为W3〉W2〉W1〉W0;不同时期灌水WUE表现为拔节水〉越冬水〉灌浆水;相同灌水处理下产量呈现S〉N、WUE表现为S〉N。综合考虑产量、贮水量、耗水量和水分利用效率,浇冬水＋拔节水秸秆还田处理是较好的节水丰产模式。

In order to effectively use water rainfall and irrigation water,in wheat-maize rotation area of south Shanxi in 2011 to 2012,a field experiment was conducted to study water-requiring,consumption properties,water use efficiency and grain yield by different irrigation time(450 m3/hm2) and straw returning treatments.The results showed that,soil water storage was W0 W1 W2 W3,soil water consumption was W0 W1 W2 W3,total water consumption exhibited W0 W1 W2 W3,WUE exhibited W2 W3 W1 W0 and grain yield represented W3 W2 W1 W0 under different irrigation.WUE represented jointing water winter water filling water under different stages irrigation.Grain yield and WUE had the same order S N under same irrigation.Based on comprehensive consideration of grain yield,soil storage,water consumption and water use efficiency,winter water + jointing water and straw returning treatment was a better mode to realize unified between water saving and high-yield.
