英文摘要	Context: Advancements in mulching drip irrigation for cotton cultivation have led to changes in plastic film width in Xinjiang, China. Concurrently, the application of brackish water for irrigation is increasingly becoming a common practice in areas where freshwater resources are limited. Objective: The effects of varying film widths and the salinity levels of irrigation water on soil hydrothermal properties, cotton growth, and yield are comprehensively investigated. Methods: A field experiment was carried out over two years (2021-2022) in Xinjiang, China. It involved testing three film widths (F1: ultra -wide film, 4.45 m; F2: wide film; 2.05 m, F3: narrow film; 1.45 m) and three levels of irrigation salinity (S1: 1 g L -1 , S2: 3 g L -1 , S3: 5 g L -1 ). Results: Wider film widths significantly increased soil water storage (SWS) and accumulated active temperature (SAT). Compared to F3, the SAT for F1 increased by 14.6-15.7 % in 2021 and by 14.1-15.8 % in 2022, respectively. Furthermore, increasing film width was found to promote cotton growth, enhance the photosynthetic capacity, and increase cotton yield by 19.2-24.1 % in 2021 and by 17.4-23.3 % in 2022, respectively. Importantly, irrigation water with a salinity level of 3 g L -1 had no adverse effect on cotton growth and development. However, an irrigation water salinity of 5 g L -1 significantly reduced cotton yield. The highest seed cotton yield and water use efficiency were observed under the S2F1 treatment, recording 5876 kg ha -1 and 11.55 kg ha -1 mm -1 in 2021, and 5905 kg ha -1 and 11.58 kg ha -1 mm -1 in 2022, respectively. Additionally, a structural equation model was developed to explore the interrelationships between the soil hydrothermal environment, cotton growth, photosynthetic capacity, and seed cotton yield. Conclusions: The findings highlight the benefits of using ultra -wide film (4.45 m) in conjunction with irrigation water having a salinity level of up to 3 g L -1 . This combination significantly improves cotton yield and water use efficiency, showcasing a promising approach for sustainable cotton cultivation in semi -arid regions.
