摘　　要：在汾河灌区以传统的地面灌溉不覆膜种植玉米为对照,进行了玉米覆膜条件下滴灌水肥一体化技术应用试验。试验对比了两种模式下玉米生长动态、耗水量和耗水规律,以及灌溉、施肥、产量和经济效益等。结果表明:膜下滴灌玉米与不覆膜地面灌溉玉米耗水规律基本一致,但日均耗水量低于不覆膜玉米,且具有明显的节水、减肥、增效、增产和增收作用。提出确定膜下滴灌灌溉定额方法、玉米膜下滴灌水肥一体化灌溉制度和施肥制度,可为汾河灌区及我省其它条件相近地区农业生产提供借鉴和参考。In the Fenhe Irrigation District,the application test of drip irrigation water and fertilizer integration technology under the condition of maize mulching was carried out with the traditional surface irrigation without mulching maize as a contrast.The experiment compared the growth dynamics,water consumption,and water consumption patterns of corn under two modes,as well as irrigation,fertilization,yield,and economic benefits.The results show that the water consumption patterns of drip irrigation corn under plastic film are basically the same as that of ground irrigation corn without plastic film,but the daily average water consumption is lower than that of corn without plastic film,and it has significant water-saving,fertilizer-saving,efficiency improvement,yield increase,and income increase effects.The method for determining the irrigation quota was proposed,as well as the irrigation scheduling and fertilizer regime of integrated water and fertilizer technology for corn drip irrigation,which can provide reference for agricultural production practices in Fenhe Irrigation District and other areas in our province with similar conditions.
