The cotton-growing region in Southern Xinjiang is plagued by perennial drought and water scarcity, there a lack of research on the irrigation mechanism for “one film, three tubes, four rows” new model dry sowing wet emergence cotton. Therefore, this experiment explores optimal regime cotton under planting Xinjiang, where two-year field plot was conducted. Three levels (W1: 360 mm, W2: 450 W3: 540 mm) were set, with replications each, to study effects different amounts growth, soil content (SWC), productivity (IWP), (WP), yield (Y). Additionally, AquaCrop used optimize regime. results showed that amount significantly affected plant height, stem diameter, leaf area index following order W3 > W2 W1. Compared W1 treatments, final biomass (B) average SWC treatment increased 32.71%, 19.59% 8.26%, 3.23%, respectively. seed higher than other being 6575.91 kg/ha 2023 7252.16 2024. IWP WP inversely related amount. After two years data calibration validation, good simulation performance canopy cover (CC), B, WP, Y (with concordance d ≥ 0.904 coefficient determination R2 0.846). Among 11 simulated scenarios (ranging from 660 mm 30 increments), but began decline slowly beyond 570 peaking at 7.45 t/ha, 1.307 kg/m3 1.294 kg/m3, Considering both conservation increase, an level or one-film, three-pipe, four-row pattern sowing, can achieve yields, benefiting sustainable production local industry.
