| Abstract: | According to the planting experiments under simulated soil columns of large scale. The soil water and salt and the other relative data were obtained by a series of monitor instruments. The changeable characteristic of water and salt regime was explained. Also, the relative analyses and portrait study were made, especially with tow influencing factors: climate and plant. Therefore, we can deduce the regulations of changes in water and salt regime in soil under planting. It can provide a foundation for building water and salt regime models. |
