To systematically sort out the historical context and cultural connotation of plantains introduction and planting in Beijing, the method of literature research and image mutual verification was adopted, combined with the perspective of garden history, botany and culturology. On the basis of summarizing the name evolution, plant characteristics and national planting history of plantains, the introduction process, application scenarios and planting techniques of plantains in Beijing were emphatically studied. The research shows that the introduction of plantains in Beijing began in the royal palace garden (Xiyuan plantains garden) in the early Ming Dynasty, gradually expanded to private courtyards (such as Gongwangfu and Shaoyuan) in the Ming and Qing Dynasties, and continued to be used in the agricultural experimental field and private houses. Restricted by the warm temperate monsoon climate, plantains in Beijing adopt the seasonal protection technology of 'open field planting in summer courtyard and overwintering in greenhouse / warm room / cellar'. Plantains, red banana and canna have name confusion in historical records, which needs to be combined with morphological characteristics and planting environment. Although limited by the lack of data, it is difficult to fully present its historical evolution, the textual criticism of the history of the introduction. However, the planting methods of plantain has reference significance for the related research on the introduction and planting history of other plants originating in the south, and can provide reference for the historical research on the introduction and planting of other types of plants. At the same time, it also provides a comprehensive research paradigm of 'literature + image + skill' for the textual research of the introduction history of southern plants in the northern region, which has reference value for promoting traditional plant culture and guiding modern garden plant configuration.
