【Objective】 Surface water evaporation (Ep) in greenhouse is often used as a reference in irrigation management. The purpose of this paper is to present a model to estimate it. 【Method】 The model was derived based on meteorological data and pan-evaporation measured from March to July in 2020 and 2022. The relationship between Ep and meteorological data was analyzed using the principal component method, from which a multiple linear regression model was developed to estimate Ep. 【Result】 Ep increased as time elapsed, with its average increasing from the range of 1.84~1.94 mm in March to the range of 3.77~5.15 mm in June in both 2020 and 2022. Ep was influenced by radiation and relative humidity the most. Photosynthetically active radiation had the highest correlation with Ep, with their correlation coefficient being 0.852 (P |
