摘　　要：采用裂区设计方法,研究节水抗旱组合技术措施(坐水种、苗期补灌和垄作区田保水技术集成)下玉米产量形成因素及水分利用效率的影响。结果表明:坐水种、苗期补灌都起到了较好效果,在该试验年,供水总量相同的条件下,补水比坐水能起到更好的作用;从垄作区田的效果来看,有区田的处理比无区田处理得到更好结果。Adopting the split sections design method, the author studied the influences of water-saving and anti-drought combined technological measure (bed-irrigating sowing, seedling stage mending irrigation, and ridge plotted field water conservation) on maize yield formation factors and water utilization efficiency (WUE). According to the results, bed-irrigating sowing and seedling stage mending irrigation have rather better effects; under the condition of same water supply gross, mending irrigation has better effect than bed-irrigation in the experimentation year; from the effect of ridge plotted field, the disposals of farmland with split sections have better result than those of farmland without split sections.
