- Abstract:
-
The measurement of evapotranspiration for the potted plant could take as required water index for the fitted plants and could quantify these changes of microclimate at local region.The evapotranspiration model also could incorporate into the microclimate model to quantify the humidity ratio of the inner air. The purpose of this study is to utilize solar radiation (Rs) and saturated vapor pressure difference (VPD) to get evapotranspiration (ET) physical model. In order to get the best model, physics theorem, mathematics theorem, and statistics tools combined to infer evapotranspiration model. The weight measurement technique was adopted and a measured device was established.According to micrometeorology, solar radiation and vapor pressure margin are function of evapotranspiration. The evapotraspiration was studied as a function of solar radiation and vapor press deficit by physical formula proposed and regression analysis. The experiment results indicated that the evapotranspiration was significant.
