摘　　要：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 under the condition of drip irrigation under mulch,change its irrigation quota,irrigation times,then make different experimental 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 irrigation system on yield indexes. through studying the yield,water consumption and irrigation water and get its water use efficiency,irrigation water productivity and comprehensive equity consideration so as to determine optimal irrigation system.

关 键 词：膜下滴灌 灌溉制度 玉米 耗水量 水分利用效率
