晋南盆地灌水、秸秆还田对小麦产量及水分利用效率的影响
The Effect of Different Irrigation and Straw Returning on Wheat Yield and Water Use Efficiency in the Basin of the South of Shanxi
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450 m3/hm2）、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W0W1>W2>W3；总耗水量依次为W0W3>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 2011-2012, 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.
