| 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0-20 cm,30-60 cm和20-40 cm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. |
