摘要:

咸水灌溉作为缓解水资源紧缺的重要途径受到广泛关注,但其对作物产量及水分利用效率的影响机理仍不清晰。本研究通过Meta分析,整合了57篇文献中的727组数据,系统评估不同作物类型、气候条件、土壤性质及灌溉水平下咸水灌溉对作物产量、水分利用效率(WUE)和灌溉水利用效率(IWUE)的影响。结果表明:咸水灌溉显著降低了作物产量、WUE和IWUE。其中,在高盐度灌溉条件(ECi>3.0 dS/m)条件下,各项指标的下降幅最为显著,产量、WUE和IWUE分别下降了24.0%、5.5%和14.8%;而微咸水(ECi≤3.0 dS/m)对作物的的影响相对较小,表明适度盐度的灌溉水在一定条件下可减轻对作物的负面效应。气候与土壤因素对咸水灌溉的效应具有显著调节作用。在湿润地区(年降水量>800 mm),咸水灌溉的负面影响较弱,而在干旱及半干旱区,其影响则更为显著。壤土和黏土较砂土更能缓冲盐分胁迫。适宜灌溉量(100~300 mm)可显著提升作物产量与水分利用效率,且在咸水灌溉条件下作用更为突出。基于以上研究结果,本研究建议:在中国干旱半干旱地区实施咸水灌溉时,应优先选择壤土或黏土条件、年降水量高于400 mm的区域,并配置100~300 mm的适宜灌溉量,以最大程度地维持作物产量与水分利用效率。该研究为干旱区咸水灌溉的优化管理提供了科学依据。

Abstract:

Saltwater irrigation has received extensive attention as an important means to alleviate water scarcity, but the mechanism of its impact on crop yield and water use efficiency remains unclear. This study conducted a Meta-analysis by integrating 57 articles with a total of 727 data sets to systematically evaluate the effects of saltwater irrigation on crop yield, water use efficiency (WUE), and irrigation water use efficiency (IWUE) under different crop types, climatic conditions, soil properties, and irrigation levels. The results showed that saltwater irrigation significantly reduced crop yield, WUE, and IWUE. Among them, the decline was most obvious under high salinity irrigation conditions (ECi>3.0 dS/m), reaching 24.0%, 5.5%, and 14.8% respectively. The influence of slightly saline water (ECi≤3.0 dS/m) was relatively small, indicating that moderate salinity irrigation could alleviate the adverse effects on crops under certain conditions. Climate and soil factors had a significant regulatory effect on the irrigation effect of saline water. The negative impact was weaker in humid areas (annual precipitation >800 mm), while it was more pronounced in arid and semi-arid regions; loam and clay soils could better buffer salt stress than sandy soils. Appropriate irrigation volume (100-300 mm) could significantly increase crop yield and water use efficiency, and its effect was more prominent under saline water irrigation conditions. Based on the above results, this study suggested that when implementing saline water irrigation in arid and semi-arid regions, loam or clay conditions with an annual precipitation of more than 400 mm should be prioritized, and an appropriate irrigation volume of 100-300 mm should be configured to maximize the maintenance of crop yield and water use efficiency. This research provides a scientific basis for the optimized management of saline water irrigation in arid areas.
