| 摘要: |
| 【目的】探究作物根系对微咸水灌溉的适应性机制。【方法】基于CiteSpace软件，对1994—2024年中国知网2 773篇中文文献及1994—2023年WOS核心库1 967篇英文文献进行可视化分析，解析不同耐盐性作物根系形态对微咸水灌溉的响应机制。【结果】文献产出时间分布显示该领域研究呈增长趋势，在主要发文国家中，中国和美国在该领域科研合作中较为普遍，在合作紧密度方面，各国合作多元化且相对均衡。关键词共现揭示研究热点集中于作物根系生长深度与分布、吸水及养分吸收能力、适应机制方面，如“微咸水”、“产量”、“膜下滴灌”高频关键词。微咸水灌溉条件下，作物根系展现出多种适应策略，部分作物根系如棉花、南瓜、向日葵向深层发展，以获取稳定的水分和养分；而另一部分作物根系则倾向于在浅层分布，与作物特性和土壤质地有关。在形态结构方面，作物根系出现了变粗壮、根毛数量增加、分支数量和长度调整等多种变化。不同耐盐性作物其根系形态和结构存在明显差异，例如强耐盐性作物如棉花、向日葵等根系更发达，能够深入到土壤深层；而不耐盐作物如水稻、大豆等根系多集中在表层或浅层，生长受到抑制。【结论】微咸水灌溉显著影响了作物根系构型，作物通过改变根系的生长深度、分布格局、形态结构等方式来适应盐分胁迫环境，未来应进一步探索作物根系对微咸水灌溉的适应性机制，探索与其他农业技术的协调应用。 |

| Abstract: |
| 【Background】Soil salinization threatens 37% of global irrigated areas. Since plants can modify their root systems to ameliorate salinity stress, understanding root adaptation under brackish water irrigation is important for sustainable agriculture and saline-alkali soil remediation. This paper reviews the advances and perspectives in this area.【Method】A bibliometric and systematic review was conducted using CiteSpace on 2 773 Chinese publications (1994—2024) from CNKI, and 1 967 English publications (1994—2023) from the Web of Science core database. We systematically examined the response of root morphology of crops with salt tolerance to brackish water irrigation.【Result】Our results showed an increasing research interest in this area. China and the United States lead the world in the area, with diversified and balanced international collaborations. Analysis using the keywords ‘brackish water’, ‘yield’, and ‘subsurface drip irrigation’ found that research associated with these keywords focused on studying the impact of brackish water on root depth, water and nutrient uptake, and root adaptation. Brackish water irrigation resulted in distinct root morphology. In particular, salt-tolerant crops, such as cotton and sunflower, developed deeper roots to access stable deep water and nutrients and avoid high-salinity in the topsoil, whereas salt-sensitive crops, such as rice and soybean, restricted their root growth to the topsoil. We also found that the impact of brackish water on root morphology depended on crop cultivars and soil texture, and that crops adapted to brackish water irrigation by thickening their roots, increasing their root hairs, and altering their root branching.【Conclusion】Brackish water irrigation significantly reshapes root architecture. Crops adapt to brackish water by modifying penetration depth and spatial distribution of their roots. Future research should focus on the genetic and molecular bases of these adaptive responses, as well as their integration with agronomic practices, such as drip irrigation and soil amendments, to improve tolerance of crops to brackish water-induced soil salinity. |
