Abstract:: Stem sap flow dynamics of dwarfing Fuji apple tree on the Weibei plateau were studied by means of thermal diffusion stem sap flow measurement system (TDP). The results showed that transpiration rates of apple trees under the condition of natural precipitation are similar to that under the condition of appropriate soil moisture content at the start-up time, the peak time and change curve in different months respectively, but peak size and daily evapotranspiration are different. For the year of 2009, under the condition of appropriate soil moisture content, annual transpiration is 643.80 mm compared with that under the conditions of natural precipitation which is 520.35 mm, decreasing by 123.45 mm. In the growing season of from July through September, precipitation meets the needs of transpiration basically. But in March, April, May and June, water supply and consumption is contrary conspicuously. It is very essential that strengthens water supply.
