“…The calculation methods of crop water requirement at the point scale can be summarized as the direct [10,11] and indirect methods [12,13]. Recently, the indirect method is widely adopted to calculate crop water requirement at the point scale in the world [7][8][9][12][13][14][15]. The calculation principle is based on the sufficient irrigation of crops, and the crop water requirement is mainly restricted by meteorological and crop physiological conditions.…”

“…Consequently, the crop water requirement can be obtained by firstly calculating reference crop evapotranspiration (ET0) and then correction by the crop coefficient (Kc). The Penman-Monteith method is widely applied in calculating ET0 [7,14,15], and it is featured by wide range of application and reliable calculation results [13,16,17]. Many previous studies have been conducted to estimate crop water requirement per unit area [8,9,18].…”
