In order to explore the hotspots and research trends of domestic research on biochar in tobacco agriculture in recent years,biblio-metric methods were used to analyze papers about biochar application in tobacco planting research included in the China National Knowledge Infrastructure (CNKI). The numbers,annual distribution,author information,publications and research content were statistically analyzed,and the CiteSpace V visualization software was used to predict and analyze research hotspots. The results showed that a total of 114 journal pa-pers and 81 dissertations on the application of biochar to tobacco planting were retrieved,including 8 doctoral dissertations and 73 master's dissertations. The institution with the most research in China was Henan Agricultural University,and Liu Guoshun was the scholar with the most published papers. Domestic research on tobacco biochar still lacked a stable core author group,and the number of core authors was small. Tobacco biochar application hotspots focused on tobacco quality,chemical composition and tobacco-growing soil. In recent years,re-search hotspots tended to be on the effects of biochar on soil microbial communities and heavy metals in tobacco leaves.
