英文摘要	Biodegradable film mulching (BFM) has been developed as an alternative to conventional plastic film mulching (PFM) to reduce residual plastic film in soil. However, there remains insufficient knowledge of the effect of the disintegrated area of biodegradable film on the crop coefficient (K-c), particularly for different colors of biodegradable film. Therefore, the aim of this study is to evaluate the differences in K-c and its components under different types (biodegradable film and plastic film) and different colors (transparent and black) of agricultural film mulching using the dual K-c method. A 2-year experiment was conducted during the 2018 and 2019 growing seasons to calibrate and validate the dual K-c method. There was good agreement between the estimated K-c and observed K-c under different mulching treatments, with an average Willmott's index of agreement (IA) of 0.96 and coefficient of determination (R-2) of 0.88. The evaporation coefficient (K-e) was significantly increased under BFM by 30.9% compared with that under PFM, during the middle and late crop growth stages, whereas the basal crop coefficient (K-cb) and water stress coefficient (K-s) decreased owing to low soil moisture under the large disintegrated area of biodegradable film. The corresponding soil evaporation (E) and transpiration (T) under BFM were increased and decreased, respectively. Moreover, there were significant differences in K-c and actual evapotranspiration (ETc) components under different colors of agricultural film during the crop growth season. K-c, T, and E under black film mulching (plastic film and biodegradable film) were on average 5.1%, 4.3%, and 5.6% lower than those under transparent film mulching. In general, black biodegradable film mulching (BBFM) is recommended as a viable option to replace transparent biodegradable film mulching (TBFM) in arid regions due to its low soil evaporation.
