Abstract
Laboratory column experiment and numerical simulation were performed to understand soil water transport by plant water uptake and formation mechanism of salt accumulation. After illuminance level raised, temperature and volumetric water content (VWC) in the column were also raised, then water level of Marriott tank was lowered. The rise of VWC may be related to upward movement of solute with water. The results of adsorbed ion distribution showed variability. It seems results of repeated ions adsorption transported by plant water usage. Observed Sodium distributions were agreed well with the root distribution. The dense part of root had higher water absorption rate. According to the numerical results, cation exchange reaction and plant water uptake by root distribution should be considered in the modeling to understand qualitative distribution of chemical components.
