摘要：

The effects of silt-laden Yellow River irrigation water on the properties of reclaimed dune sands were investigated at the Shapotou Research Station in Ningxia Autonomous Region, China. The practice resulted in distinct and rapid improvements in the physical and chemical properties of reclaimed desert soils. Irrigation led to the development of sandy loam topsoils, with up to 39 cm accumulating over 25 pears of treatment. These topsoils had improved structure, greater soil organic matter contents and smaller bulk densities than buried desert sands. Geochemical analyses suggested river silt and sheep manure were making distinctive contributions to the improved soil fertility, with older topsoils having progressively greater concentrations of Ca, Mg, K, P, S, Fe, Mn and Zn. Soil Cr concentrations are increasing and it seems appropriate that changes in heavy metal concentrations in irrigated soils are monitored.
