Abstract:

To comprehensively and systematically grasp the research status, hotspots, and development trends in the field of orchid fertilizer, relevant literature published between 2005 and 2025 was collected from the China National Knowledge Infrastructure (CNKI) and the Web of Science (WoS) core databases. Utilizing CiteSpace software, a visual analysis was conducted through bibliometric methods, including the analysis of publication volume, institutional collaboration networks, keyword co-occurrence, clustering, and burst detection. The results indicated that the overall annual publication volume in this field remained relatively low but showed a fluctuating growth trend over the specified period. International research in this domain started earlier and demonstrated stronger continuity, showing a recovery trend in recent years. In contrast, domestic research experienced a boom between 2009 and 2013, followed by a rapid decline. Regarding institutional collaboration, both domestic and international networks exhibited the characteristics of ‘overall dispersion and local agglomeration’. However, the closeness of international collaboration was superior to that of domestic collaboration, with core institutions forming small-scale collaborative networks respectively. The research hotspots have gradually deepened from cultivation techniques to physiological mechanisms. Domestic studies mainly focused on the industrialization technologies of specific varieties, such as Phalaenopsis and Cymbidium hybridum, while international research placed more emphasis on fundamental regulatory mechanisms, including nitrogen nutrition and mineral nutrition. According to the comprehensive analysis of the statistical data, it can be inferred that the regulation of the flowering period, nutrient absorption, environmental stress tolerance, and the optimization of cultivation substrates will become the frontier research directions in this field. It is suggested that future efforts should strengthen cross-institutional coordination and international cooperation, further deepening the research on nutritional physiological mechanisms and intelligent fertilization technologies.
