| Abstract: | Large-scale soil column experiments for simulation water-salt movement in clay interlayers under normal growing conditions were carried out in an easily-salinized region for different textures of soils and groundwater conditions in the Huang-Huai-Hai alluvial plain of China.In this study,the 20-year measurement was analyzed to examine the effect of clay interlayers on soil water-salt movement in easily-salinized regions.Results show that the clay interlayer has a significant positive effect on the water-hol... |
