Bibliometric Analysis of Seedling Substrate Literature Based on CiteSpace
This study conducts a systematic bibliometric analysis of literature on the topic of"seedling substrates"using the CiteSpace software,based on data from the China National Knowledge Infrastructure(CNKI)database.By examining keyword co-occurrence,cluster analysis,and research institution collaboration networks,the study reveals the development trends and re-search hotspots in the field of seedling substrates.The results show that since 1992,research in this area has progressed through initial development,sustained growth,and the emergence of new research platforms.The research network remains relatively fragmented,with room for enhanced collaboration among research institutions.The focus of research has shifted from the basic characteristics and applications of substrates in the early stages to substrate improvement techniques,optimization for specific crops,and the use of eco-friendly materials.In recent years,the emphasis has further shifted towards the precise regulation of the physical and chemical properties of substrates and their comprehensive impact on plant growth.Looking ahead,with increased interdisciplinary collaboration and diverse research methods,research on seedling substrates is expected to make new break-throughs in intelligent management and the application of eco-friendly materials.
