Evapotranspiration (ET) is a typical biological environmental model. This model can be incorporated to the greenhouse microclimate, ecological environment and physiological environment model. ET is the primary process affecting the leaf temperature, crop water requirement and greenhouse microclimate. Affecting factors involved include air temperature, leaf temperature, air relative humidity, wind speed and solar radiation. In this study, the simple form of ET models of tomato in subtropics greenhouse were proposed to observe the main influencing factors of ET. The significant effect of these factors were evaluated with statistical regression technique. The results indicated that both the solar radiation and vapor pressure deficit are the significant factors on ET values. Solar radiation was the dominating factor in the high radiation condition. The variable of solar radiation can explain 80% of the variation of the evapotranspiration for tomato. It provides a simple way to control the irrigation works.
