摘    要:在额尔齐斯河流域地下水位浅埋条件下薄层砂性土壤的灌区内,2002—2003年进行两年田间试验,采用田间垂直入渗试验法计算分层土壤蓄水量,研究大水漫灌下薄层砂性土壤水分变化的规律,分析当地大水漫灌是否合理。试验结果表明,大水漫灌下田间水分利用率为30%~40%,田间土壤水分变化主要发生在根区土壤0~-50cm深度,根区土壤层的蓄水能力为100-125mm。

关 键 词:薄层砂性土壤  土壤水分  地下水位浅埋

Abstract:A field experiments was conducted to study changes of thin and sandy soil moisture in irrigation area of Irtysh River Basin in 2002 and 2003. The water storage capacity of soil different layers was counted by the vertical infiltration method in the field,and the law of change of thin and sandy soil moisture under full irrigation was investigated. The experiment result showed that moisture utilization ratio under full irrigation was 30%-40%. The change of field soil moisture mainly depended on the 0-50 cm depth around the plant root. The moisture storage capacity of soil layer around root was 100-125 cm.
Keywords:thin and sandy soil layer  soil moisture  shallow water table
