Abstract：Stem-flow gauge can measure plant flow rate directly. In this paper, we have evaluated the value of the instrument through farmland experiment and theory calculation. The result shows that the change of wheat transpiration has strong correlation with solar radiation in daytime, and the solar radiation is the most important factor in deciding the wheat transpirtion in the day. On the other hand.in nighttime, the transpiration mainly depend on temperature,windspeed, and saturation vapor pressure.etc. In usual night, there is no transpiration, but if the windspeed and temperature is high enough. winter wheat will have a little transpiration,and the transpiration changes in a certain regular pattern in clear night.
