摘　　要：为了提高半干旱区玉米产量，以玉米品种先玉335为试验材料，采用大区对比的方法，对平作膜上精播技术进行研究。结果表明：平作膜上精播处理比常规垄作处理地温提高2～3℃，储水量增加13．13％，产量增加13．87％，水分利用率增加20．40％。平作膜上精播技术能够提高耕层土壤温度，与常规垄作覆膜相比具有良好的集雨保墒效果，能促进玉米生长发育，显著提高玉米产量和水分利用率。In order to improve the yield of maize in semiarid region ,taking Xianyu 335 as the experimental mate-rials ,using the method of regional contrast ,accurate sowing technique of flat planting and film mulching were studied .The results showed that the accurate sowing technique of flat planting and film mulching could increase the ground temperature by 2~3℃ ,soil water storage by 13 .13% ,yield by 13 .87% and water use efficiency by 20 .40% than control .Accurate sowing technique of flat planting and film mulching could improve the topsoil temperature which had better effect on rain collection and water retention than the ordinary ridge tillage film covering technique ,and it could promote the growth and development of maize ,as well as increase crop yield and water use efficiency significantly .
