| Abstract: | An experimental research on the daily variation of evapotranspiration in wheat field and evaporation on bare soil under different soil moisture was conducted. The relationship between evaporation on bare soil and evapotranspiration in wheat field was discussed in this paper. Also, the author analyzed the characteristics of daily evapotranspiration in field, the relationship between field evapotranspiration and air temperature, the relationship between field evapotranspiration and solar radiation, and the relationship between field evapotranspiration and soil moisture. In the end, the equations of evapotranspiration and relative soil moisture were established. |
| Keywords: | evapotranspiration in wheat field evaporation bare soil daily variation soil moisture |
