Abstract:

Selenium-enriched rice, as a type of nutritionally fortified agricultural product, has attracted considerable attention in recent years. Based on relevant literature indexed in the Web of Science Core Collection from 2005 to 2025, this study employed bibliometric methods combined with VOS viewer software for visual analysis, systematically reviewing the developmental trajectory and frontier dynamics of the selenium-enriched rice field. The results indicate that the annual number of publications in this field shows a steady growth trend, with research interest continuously increasing. China ranks first globally in terms of total publications, citation frequency, and H-index, serving as the core research force in this area, with domestic policy orientation providing the main driving force for its development. Environmental science, plant science, and food science and technology are the dominant disciplines, exhibiting significant interdisciplinary integration in their distribution. Key current research hotspots include selenium biofortification, interaction effects between selenium and heavy metals (such as cadmium and arsenic), transformation patterns of selenium species, and food safety and health risk assessment. A multi-scale progressive research system has been established, covering key dimensions such as elemental biogeochemical behavior in agroecosystems, element migration, transformation, and control mechanisms in soil-rice systems, agronomic fortification strategies, and physiological and molecular regulation mechanisms. This study providing important references for researchers to identify research directions and conduct innovative studies, as well as for decision-making bodies to optimize research layout and formulate industrial policies.
