Optimization of Soil Moisture Environment by Applying Simulation on Sub-irrigation Method (II) : Reappearance Trial by Using Conformal Mapping Method in the Distribution of Soil Moisture Tension

摘要

This study was conducted to clarify the distributions of soil moisture tension in root zone under different conditions in case of applying the continuous sub-irrigation method by using negative pressure. That is, the different conditions were divided into six groups. The first is the rate of transpiration to evapotranspiration, the second the vertical direction of water source, the third the horizontal direction of water source, the forth the space of water source, the fifth the vertical direction of two water sources, and the sixth the horizontal direction of two water sources. Consequently, the differences of the distributions of soil moisture tension which were gained in this study were recognized larger than those in the previous paper.
