| Abstract: | The laws of soil moisture variations on the state of evapotranspiration in Heihe areas has studied. It has made observations and analyses on diurnal variations of the water potential, stomatal resistance and transpiration rate of spring wheat under various soil moisture conditions and different leaf positions. Comparison of the water potentials of leaf, sheath and culm has done. The relationships of soil moisture with leaf water potential and stomatal resistance as well as the effects of soil moisture on them have also been analyzed and the relationships have been expressed by empirical equations. |
