摘　　要：通过田间试验,探讨了绿洲灌区地膜覆盖方式与灌溉制度的耦合效应。结果表明,灌水水平和种植方式显著影响玉米产量,中水全膜平作产量最高,达13 456.2kg/hm2。不同处理各生育期耗水量随灌水水平的提高而增加,灌水水平、种植方式和覆膜方式对总耗水量的互作效应显著;随灌水量的增大,玉米WUE呈降低趋势,同等灌水水平和覆膜方式下,平作WUE高于相应垄作种植。绿洲灌区以中水全膜平作种植为宜。The coupling effect of plastic film mulching and irrigation schedule was explored in the oasis irri- gated area through the field experiments. The results showed that the maize yield was significantly affected by irrigation level and planting mode, the yield of 13 456.2 kg/hm2 was the top in the treatment of middle irrigation and whole film and flat. The water consumption increased with the increase of irrigation water a- mount in each growth period under different treatments, and the total water consumption was significantly affected by irrigation level, planting mode and mulching pattern. WUE decreased with the increase of irri- gation water amount, and WUE in flat treatment was higher than that in the corresponding ridge planting treatment at the same irrigation level and film mode. The mode of middle irrigation, whole film and flat treatment was recommended in the oasis irrigated area.
