- Abstract:
- Dynamic of soil water and salt of salt leaching with drainage ditch was studied by making use of numerical methods in this paper.Soil water-salt transport could be considered approximately as one-dimensional movement at half distance of two ditches,in which ratio and depth of desalinization reached the minimum value and formed symmetric distribution.During the entire washing process,changes of salinity were always slightly lagged behind changes of moisture content.Through analyzing the resalinization ratio of different salinity profile after leaching,it is found that the relationship between resalinization ratio and the salt content followed the principle of power function.The salt leaching system of different salt content was established.
