| Abstract: | Research on the experiment data of soil moisture and biomass during the period of soybean in Gannan Experimental base, potential evapotranspi ration was calculated with water balance method. We has analyzed the change of t he estimation of evaportranspiration. By the survey of LAI in each growing stage , it is discussed that the influence of LAI on the evaportranspiration. Based on the data for routine meteorology, effect of each meteorological element on evap oration capality was analyzed. |
