| Abstract: | According to the reference crop potential evapotranspiration model (FAO-Penman-Monteith),which modified by crop coefficient,radiation stress coefficient and wind speed reduced coefficient,the wheat potential evapotranspiration (ET_(pp)) model in an apple-wheat intercropping in the hilly land of Taihang Mountain was developed.This modified model was tested with the experimental data from LI-1600 steady state porometer.The results showed that the estimated value of ET_(pp) had good agreement with the measured and that the linear correlation coefficlent (R~2) between them was 0.963 0(n=51),the average relative error was 9.65%,t=0.075<
