摘　　要：2009年在黑龙江省杜蒙县进行了玉米大垄双行覆膜喷灌与常规种植喷灌的对比试验研究。在玉米全生育期,对土壤水分指标进行了观测,分析了玉米生育期土壤水分动态变化过程,在收获后对玉米进行测产分析。结果表明,大垄双行覆膜采用喷灌与常规耕作相比,水分利用效率提高;具有较好的节水作用;玉米增产效果明显。Developing a reseach about comparison bewteen the film-mulching of double line width ridge of springkler irrigation and general planting of springkler irrigation in Yixin Towship Dumeng country of Heilongjiang Province.Making observations about the soil moisture index during the whole growth period,and analyzing the dynamic change of soil moisture in farmland and yield of maize in the harvest period.The results indicated that the film-mulching of double line width ridge treatment that using the sprinkler irrigation could effectively increase the soil water content and have fine functions of water-saving,and the yield increase effect of maize was obvious.
