英文摘要	Determination of evaporation (E) and transpiration (T) in tea fields separately is important in developing precise irrigation scheduling and enhancing water use efficiency. In this study, the Shuttleworth-Wallace (S-W) model was applied to simulate the variations of E and T based on the data from 2015 to 2018 in a tea field in southeast China. The dual crop coefficient (D-K) method recommended by FAO-56 was also applied to calculate E and T, using the same data set to compare with the S-W model. The measured crop coefficient (K-c) ranged from 0.43 to 1.44 with the average value was 0.90 during 1-150 DOY (days of year), and the measured K-c tended to be stable with the average value of 0.83 during 151-365 DOY in 2015. The S-W model estimated ETc with root mean square error (RMSE) and R-2 of 0.45 mm d(-1) and 0.97, while for the D-K method the values were 0.61 mm d(-1) and 0.95. Therefore, both approaches could estimate the E and T separately in tea fields in southeast China, however, the D-K method had a slightly poorer accuracy compared to the S-W model in the estimation of ETc.
