摘　　要：[目的]为枣园滴灌及水肥耦合提供理论数据支持。[方法]以农二师36团戈壁地滴灌枣园为试验材料,用手持式土壤水分测量仪测量在相同滴头流量下不同滴灌时间上枣园土壤水分的时空变化。[结果]在滴水6 h后0,cm处垂直深度中最大含水量位于30 cm处,为20.9%;在滴水24 h后0,cm处垂直深度中最大含水量位于20 cm处,为22.3%;在停水12 h后0,cm处的垂直深度最大含水量位于0 cm处,为6.1%。[结论]戈壁地枣树的根系主要集中在30 cm处。[Objective] The research aimed to provide the data to support the drip irrigation and water coupling in jujube orchard.[Method] The gobi drip irrigation jujube orchard of 36 mission of the Second Agricultural Division was taken as test material.Hand-held meter was used to measure soil moisture to study the spatial-temporal changes of soil water in gobi jujube orchard under the condition of the same drops head flow and different drip irrigation times.[Result] In drop 6 h,the maximum moisture at 0 cm department vertical depth was at 30 cm department,reaching 20.9%.In drop 24 h,the maximum moisture at 0 cm department vertical depth was at 20 cm department,reaching 22.3%.In suspension 12 h,the maximum moisture at 0 cm department of vertical depth was at 0 cm department,reaching 6.1%.[Conclusion] Roots system of jujube in gobe was mainly in 30 cm place.
