For improving precipitation use efficiency of millet in rain-fed region of Loess Plateau,the middle weighing lysimeter,micro-lysimeter and biological indicators were combined in this experiment to determine the soil evaporation and millet evapotranspiration during the whole growing period of millet in Liudaogou watershed of Shenmu County.The results showed that the Logistic model could simulate the growing processes of millet height and coverage,the correlation coefficients of simulated and measured values ...
