Outline of Final Research Achievements

The effect of phytoremediation for desalinization about beat and sunflower was investigated at the salinized field in the arid region of China. Monitoring system of weather, soil water content, soil electrical conductivity and ground water level was set at the field and the data was collected. Moreover, root distributions were observed by sampling plants.
As a result of analysis, it is clear that the accuracy of the numerical simulation with soil water movement in the field was increased by using soil water retention curve modified by considering root distribution and textural change. As a solute transportation, soil water equivalent concentration could be estimated by simulated values of water content and electrical conductivity using chemical components values of irrigation water, groundwater and fertilizer analyzed by sampling material.
