The study was focused on the amount of available water in soil, hydraulic conductivity in soil-root system from different root zones, sap flow from root to stem, compensatory effect of root water uptake, the fruit growth and physiological attibutes, evaporation and transipiration, and plant water use efficiency. Experiment plants involved apple tree, grape, peach, etc. Fruit trees were irrigated in both half root zones or water was continuously supplied to the one-half and the other half kept dry(fixed partial rootzone irrigation, F), or water was alternatively supplied to two halves (alternative partial rootzone irrigation, A).

Main creative points of the thesis are as following:1. It is the first time to apply 2-D and 3-D turbulent model of the air-water two phases flow to the study on hydraulic properties of groyne. It makes description of the turbulent flow field to be possible precisely. This offers a more accurate method to determine the water surface in channel improvement.2. Based on the results of experiment and simulation for 3-D turbulent model of air-water two phases flow, a new formula to compute the height of damming is built.3. Based on the 2-D mode and the formula to compute the height of damming, the subdivision method of 2-D computation for water surface at upstream and downstream.
