采用玉米作为试验材料，进行大田玉米的膜下滴灌灌溉制度试验研究，改变其灌溉定额、灌水次数，设置不同的试验处理，观测降雨量、土壤含水量，运用水量平衡方程分析玉米耗水量。对收获的玉米进行考种与测产，得到一系列产量指标；分析灌溉制度对产量指标的影响。通过分析产量、耗水量及灌溉水量，从而得到水分利用效率、灌溉水生产效率，综合考虑最终确定最优的灌溉制度。

Regard Maize as experimental material and performance the experiment of irrigation system about corn field un-der the condition of drip irrigation under mulch, change its irrigation quota, irrigation times, then make different experi-mental processing, through observing rainfall, soil water content and analysis water consumption of maize by using water balance equation.Measuring production of mature maize and obtain a series of yield indexes, analysis the effect of irriga-tion system on yield indexes.through studying the yield, water consumption and irrigation water and get its water use effi-ciency, irrigation water productivity and comprehensive equity consideration so as to determine optimal irrigation system.
