The yield and quality of tobacco are significantly influenced by the quality of upper leaves,and improving the availability of upper leaves is a hot and urgent problem to be solved in the tobacco industry.Based on the literatures on the quality of upper tobacco leaves in China National Knowledge Infrastructure(CNKI),we constructed a co-occurrence knowledge graph of authors,institutions,keywords using bibliomet-ric methods through CiteSpace software.The current research status and hot frontiers in the field of usability of upper leaves in tobacco were an-alyzed.Results showed that the research on improving the usability of upper leaves was always an urgent problem to be solved for the high-quali-ty development of the tobacco industry,and the number of researches kept stable at about 70 articles from 2020 to 2023.The main directions of researches in the field of upper leaf usability were enhancing the sensory and appearance quality of tobacco leaves,mature harvesting and prep-aration and baking.Reasonably topping and leaving leaves,harvesting at maturity and scientifically baking were the key technologies to enhance the upper leaf usability.In the future,more attention could be paid to the research mechanism of improving the usability of upper leaves through the application of organic fertilizers and the improvement of tobacco field quality.
