中文摘要	基于塔克拉玛干沙漠腹地田间试验,对比分析了不同保墒措施对沙拐枣林地土壤水分和生长的影响. 结果表明:(1)保墒措施对土壤水分垂直分布的影响明显,虽然灌溉初期处理间差异不大,但在灌溉周期末差异较大;覆膜、覆沙、蒸发抑制剂(Guilspare~R)分别提高了0--20cm,30--60cm和20--40cm的土壤含水量. (2)保墒措施对灌溉周期内沙拐枣清晨水势和午后水势均有显著影响,不同处理的清晨水势大小顺序为:地膜>覆沙>蒸发抑制剂>对照(CK);蒸发抑制剂处理的午后水势却大于地膜. (3)与对照相比,保墒措施下沙拐枣的水分环境得到了较大改善,地膜和覆沙处理下沙拐枣生长状况较好,蒸发抑制剂处理的长势较差
英文摘要	Based on field experiment in the hinterland of Taklimakan Desert, the vertical distribution of soil moisture and growth characteristics of Calligonum mongolicum under different treatments were contrasted and analyzed. Results showed that (1) the vertical distribution of soil moisture was affected obviously by different soil moisture conserving treatments. Differences among treatments were not big in the early irrigation interval, but a reverse phenomenon was observed in the later irrigation interval. Soil moisture content increased at depths of 0-20 cm, 30-60 cm, and 20-40 cm under treatments of mulching film, mulching sand, and spurting inhibitor, respectably.(2) Both predawn and postmeridian water potential were affected obviously by different treatments. By predawn water potential, the order was mulching film>mulching sand >spurting inhibitor>CK, but postmeridian water potential of mulching film was less than spurting inhibitor.(3) Comparing with CK, it was clear that hydrological environment of plant was improved with soil moisture conserving treatments. The growth condition of Calligonum mongolicum under mulching film and mulching sand was better than spurting inhibitor
