Abstract:: In order to solve the problem of land degradation in Yellow River water pumping irrigation area to study the planting alfalfa on the physical and chemical properties of soils in salinization soil with stratified sample of soil testing methods on Hongyue village of Jingtai county. The soil bulk density, conductivity and pH value, soil organic carbon and nitrogen contents and soil physical properties in the salinization soil grown alfalfa in areas such as the relevance of an analysis after the cultivation were examined. The results showed that: planting alfalfa, salinization soil physical and chemical properties had changed markedly, and the sampling levels of organic carbon and nitrogen content with the years of the extension of cultivation to increase significantly, and the soil bulk density, but K⁺ and Na⁺ were a downward trend. Soil bulk density and soil organic matter and organic carbon content has a significant negative correlation, but soil conductivity and pH value of the land planted with the kind of life was no obvious correlation, indicating for planted alfalfa and industrial production on salinization land in Yellow River water pumping irrigation area is the realization of secondary salinization in Yellow River water pumping irrigation area of land to restore governance, sustainable development and effective way.
