Abstract

Abstract:

This study investigates the effects of fertility factors on Panax ginseng growth through hotspot extraction and evolutionary analysis of research themes based on the Latent dirichlet allocation （LDA） topic model. A corpus of 304 scholarly articles in the field of soil fertility factors influencing ginseng growth was systematically analyzed using the LDA topic model. The optimal number of topics was determined by evaluating topic perplexity and pyLDAvis visualization. High-frequency topic keywords were then employed to identify research hotspots and summarize their evolutionary trends. Four core themes were extracted， revealing the mechanisms by which fertility factors regulate ginseng growth： Effects of Phosphorus Fertilization on Morphological Development in Panax Ginseng（Topic1）， Effects of Potassium Fertilization on Leaf Morphology in Panax ginseng （Topic2）， Microbial Modulation of Soil Enzymes Enhances Growth in Panax ginseng（Topic3）， Nitrogen Enhances Shoot Development in Panax ginseng through Foliar and Stem Biomass Accumulation（Topic4）， the theme “Microbial Modulation of Soil Enzymes Enhances Growth in Panax ginseng” （Topic3） emerged as a current research focus. This study elucidates the regulatory role of soil fertility factors in ginseng cultivation and provides a scientific foundation for optimizing soil amendments and fertilization strategies.

Key words: Panax ginseng, Soil, Nitrogen, Phosphorus fertilizer, Potassium fertilizer, Microorganisms
