Abstract

Context

Xinjiang's pivotal cotton industry requires improved irrigation management for sustainable production due to water inefficiency and salt accumulation, while alternate surface and subsurface drip irrigation with mulch (ADI) and salt leaching serve as promising solutions. Objective: Therefore, this study assessed the effects of ADI and salt leaching on soil water, salinity, desalination, cotton yield, water use efficiency (WUE) and economic benefits to identify the optimal strategy. Methods: A field experiment in 2020–2021 used two irrigation methods (ADI; DI: surface drip irrigation with mulch) and four leaching levels (0, 120, 240 and 360 mm). Leaching water was applied in three equal portions during the seedling and budding stages (DI) and flowering stage (subsurface drip irrigation). Results: As leaching levels increased, yield, desalination rate and economic benefits improved, while WUE and desalination efficiency initially increased, then decreased for both irrigation methods. Compared to DI, ADI had worse soil water conditions within the film, but this was mitigated with higher leaching levels. Notably, ADI improved soil salinity conditions, effectively offsetting yield reductions caused by water stress. Compared to DI, ADI boosted cotton yield and WUE by 3.1 %-26.5 %, desalination rate and efficiency by 24.1 %-114.5 %. Despite higher inputs, ADI outperformed DI economically in high salinity soils, with better salt control promoting higher yields. Conclusions: Overall, TOPSIS evaluation showed ADI offered superior benefits over DI. ADI with 252–336 mm leaching water (0.8 g·L⁻¹) was identified as optimal (≥95 % peak performance), balancing desalination, cotton yield, WUE and economic benefits. Significance: This recommendation strongly advocates for the positive impact of ADI in promoting sustainable development in saline agriculture.

地表与地下交替滴灌盐浸可提高棉花产量、水分利用效率、脱盐率、脱盐效率和经济效益

新疆关键的棉花产业由于用水效率低下和盐分积累，需要改进灌溉管理以实现可持续生产，而地膜交替地表和地下滴灌（ADI）和盐浸是很有前途的解决方案。目的：本研究评估ADI和盐浸对土壤水分、盐分、脱盐、棉花产量、水分利用效率（WUE）和经济效益的影响，以确定最佳策略。方法：在2020-2021年进行田间试验，采用两种灌溉方式(ADI；DI：表面滴灌覆盖)和四个浸出水平（0,120,240和360 毫米）。在苗期、出芽期（DI）和开花期（地下滴灌）等量施用浸出水。结果：随着浸出水平的提高，两种灌溉方式的产量、脱盐率和经济效益均有所提高，用水效率和脱盐效率均先升高后降低。与DI相比，ADI在膜内的土壤水分条件更差，但这与较高的浸出水平相缓解。值得注意的是，ADI改善了土壤盐分状况，有效抵消了水分胁迫造成的产量下降。与DI相比，ADI提高了棉花产量和水分利用效率3.1 % ~ 26.5 %，脱盐率和效率提高了24.1 % ~ 114.5 %。尽管投入较高，但在高盐土壤上，ADI在经济上优于DI，更好的控盐促进了更高的产量。结论：总的来说，TOPSIS评估显示ADI比DI有更好的疗效。ADI在252-336 mm浸出水（0.8 g·L⁻¹）时最优（峰值性能≥95 %），可平衡脱盐、棉花产量、水分利用效率和经济效益。意义：本建议强烈倡导ADI在促进盐碱地农业可持续发展方面的积极影响。
