Plastic‐mulched drip irrigation is widely used in arid regions, but it may aggravate root‐zone hypoxia and salinity. A two‐year field experiment based on two two‐factor designs was conducted in Xinjiang, China, during 2023 and 2024 to investigate the combined effects of irrigation‐water temperature (10°C–15°C and 20°C–25°C), aeration method (5 mg L −1 (no aeration)) and 18 mg L −1 (micro‐nano aeration) and humic acid applicati...
