“…Lysimeters allow to measure evaporation rates directly (Allen, Howell, et al, 1991; Allen, Pruitt, et al, 1991; Goss & Ehlers, 2010; Pütz et al, 2018). As Figure 1I illustrates, lysimeter columns (area 1.0 m 2 , depth 70 cm) are filled with water and two different homogeneous soil textures (particle composition and physical properties of the textures are introduced in Li et al, 2022). Evaporation rates from saturated soil textures (PE s ) and water (PE w ) were observed by the ‘automatic water replenishing Markov bottle’ (installed in the basement).…”

Potential evaporation (PE) is a significant input in many hydrological models for the estimation of actual evaporation. Evaporation from water (PE w ) is generally considered equivalent to evaporation from saturated bare soils (PE s ). The influences of the underlying surface on PE as well as the energy and vapour transfer in potential evaporation processes over different surfaces are rarely discussed. In this research, lysimeter experiments were set up to measure the diurnal cycles of evaporation from two saturated sandy soils and water at a high temporal resolution in the Guanzhong Basin, China. Evaporation from Class A Pan, meteorological variables and temperatures were also measured during the experiment. Observation results show that PE s is

Sustainable development in arid and semi-arid areas is largely constrained by water resources. Expanding ecological space is considered an effective way to conserve water resources. The innovation of this study is the analysis of water consumption in different land-use types from a complete watershed scale, which can evaluate space management against the background of returning farmland to forestland during the past 20 years, and provide suggestions for future space management in semi-arid areas. Based on meteorological data and GIS technology, the current study quantitatively analyzes the spatial and temporal variation characteristics of the water consumption of different vegetation growth stages in the Yanhe River Basin by using the improved Penman formula. The results show that the water consumption of vegetation in the Yanhe River Basin increased from 0.44 km³ in 2000 to 0.68 km³ in 2020. The water consumption of vegetation showed obvious spatial heterogeneity, with the highest value in the central Baota area (1.094 km³) followed by the western Ansai region (0.727 km³), whereas the consumption in the eastern Yanchang area is relatively low (0.483 km³). In addition, the annual average water consumption is (0.381 km³). The cultivated land consumes the most water (0.21 km3), while the woodland consumes the least (0.072 km³). The water consumption per unit area of forested land is the highest, reaching 190 m, and the water consumption of low-coverage grassland is the lowest, only reaching 50 m. Vegetation distribution change could be the main influencing factor of vegetation water consumption change in the Yanhe River Basin. Through the establishment of the sustainable development path of ecological space with water as the core, the high-quality development of ecological environments in arid and semi-arid areas will be achieved.

“…Further, ET consists of two parts, soil evaporation (E) and crop transpiration (T). Various techniques have been proposed to calculate and measure E and T and these include weighing lysimeters to measure ET, soil micro‐lysimeters to measure E, stem flow gauges to measure T, micrometeorological methods to measure ET, energy and water balance simulation models, and remote sensing methods to calculate E, T, and ET (Immerzeel et al., 2008; S. Li et al., 2013, 2022; P. Zhao et al., 2015). However, these techniques can be expensive and time consuming and estimates of ET can be complex at varying scales of measurement and calculation (Wu et al., 2017).…”

Water requirements of early‐maturing maize hybrids might be lower than those of late‐maturing maize hybrids. This study aimed to analyze the effects of different irrigation management on grain yield (GY), water uptake patterns, evaporation (E), and transpiration (T) of two maize hybrids differing in maturity via stable isotope method. The field experiment with 36 lysimeters (4 m wide × 4 m long) under rain‐shelterswas conducted with an early‐maturing (DH518, EM) and a mid‐ and late‐maturing (DH605, LM) hybrid with three replicates from 2021‐2022. Maize plants were grown under three irrigation amounts (W1, W2 and W3 was irrigated to maintain soil moisture at 45%, 60%, and 75% of field capacity, respectively) by flood (FI) and drip (DI) irrigation under rain‐out shelters. Results showed GY and evapotranspiration (ET) of EM were 8% and 12% lower, while the crop water productivity (CWP) was 6% higher than that of LM. Water uptake of both hybrids occurred mainly within 0‐60 cm soil layer during the vegetative stage. Water uptake of both hybrids occurred mainly within 0‐60 cm soil layer during the vegetative stage. Summer maize under FI absorbed more water from deep soil layer than DI in the late growth stage. Compared with LM, the water absorption depth of EM became shallower in the late growth stage. Water uptake of maize was mainly from the deeper soil under water stress conditions. E of total ET accounts for 43% under DI and 57% under FI, GY and CWP were 22% and 51% higher than those of FI. Together with choosing early‐maturing hybrids, optimization of water management with DIW3 could achieve higher GY and CWP. The optimization of irrigation method and hybrids could provide a reference for local farmers to improve grain yield and CWP.This article is protected by copyright. All rights reserved
