以夏玉米为试验材料，设置不同水分处理方式，研究了不同灌水方式夏玉米的耗水特性及其对产量的影响。结果表明：水分控制下限越高，耗水量越大；一体化垄作沟灌种植模式全生育期耗水量均低于相同水分处理的常规沟灌种植模式，蓄水保墒效果较好；不同沟灌方式夏玉米产量和水分利用效率差异显著，一体化垄作沟灌种植模式增产明显，平均增产率达8·67%，水分利用效率提高了0·23~0·36 kg/m3；过低或过高的水分处理对产量及其构成因子都会造成不利影响。

The effect s of different irrigation methods on t he consumption characteristics and yield of summer corn w ere investiga-ted based on different w ater treatments. The results show ed that ( 1) the higher t he control limit of moisture content is, the great er the water consumption is;( 2) the w ater consumpt ion of the integrated ridge tillage furrow plant ing pattern is low er than that of the conventional furrow planting pattern under the same water treatment during the growing period, and the impound-ment effect of soil moist ure is good;( 3) under different furrow irrigation methods, the corn yield and w ater use eff iciency are significantly different, and t he integrated ridge tillage furrow planting pattern generates higher yield and improves the w ater use eff iciency. The average increasing rate of yield is 8· 67%, and the increased water use eff iciency is 0. 23 to 0· 36 kg/m3;and ( 4) too low or too high moist ure treatments can cause adverse effects on the corn yield and its component factors.
