| 摘 要： | 在宁夏清水河平原选择典型地区建立了包气带水分运移试验场,对旱作条件下和灌溉条件下的冬小麦田包气带水分运移特征进行了观测研究.结果表明:该农田类型包气带水分运移特征以上渗-下渗型为主,由于地下水埋深大,任何情况下包气带水都持续补给地下水,非种植季节土壤储水为旱作冬小麦的生长提供了重要水源,灌溉显著地增大了作物蒸发蒸腾量和...

| Abstract: | A field test for vadose zone water transport was built up in typical area of Qingshuihe plain,Ningxia.The transport of vadose water in dry and irrigated winter wheat land was observed.Upward-downward transport is the domain type of water migration.Groundwater is recharged by vadose water in any time for the reason of deep groundwater level.Soil water storage in no-planting season provides important water to the growth of winter wheat without irrigation.Irrigation increases crop evapo-transpiration and leaka... |
