Abstract: Polygonatum sibiricum is a medicinal and edible Chinese herbal medicine,which has broad prospects in health care.In view of the long-term contradiction between supply and demand of Polygonatum sibiricum and the urgent need to improve the planting technology and expand the planting mode,based on the research literature on the yield and benefit of different multiple cropping modes of medicinal Polygonatum sibiricum in the past five years on the big data platform of China National Knowledge Infrastructure,the yield and benefit of different multiple cropping modes of medicinal Polygonatum sibiricum were summarized and compared through the statistics of the multiple cropping modes involved and the corresponding yield and benefit data.The reasons for the difference in yield and benefit of Polygonatum sibiricum were analyzed,and the multiple cropping modes which were beneficial to improve the yield and quality of Polygonatum sibiricum were optimized.Suggestions on the selection of planting technology and multiple cropping mode of Polygonatum sibiricum were put forward in order to provide reference for the next research on planting technology of Polygonatum sibiricum.
