A method is provided for obtaining new distant germplasm of intergeneric hybridized potato based on grafting-mentor, including the following steps: (1) using young branches, which are growing well, free of diseases, non-lignified, and from an upper part of Lycium as rootstock; (2) using seedlings of diploid primitive cultivated potato with 2-3 unfolded leaves as scion; (3) grafting; (4) conducting post-grafting management; (5) obtaining distant hybridized germplasm by using potato flower buds from the grafted plants for pollination, obtaining seeds of potato varieties after self-fertility, performing pre-germination on selfing seeds, obtaining true seed mini-tubers, and using these mini-tubers for further grafting and pollination to obtain distant hybridized seeds, performing tissue culture propagation on the distant hybridized seeds to obtain F1 asexual clone line foundation seeds.

A grafting device and a grafting method based on a UV (Ultraviolet Rays) adhesive are provided. The grafting device includes a workbench, a transfer mechanism, a seedling loading mechanism, a cutting mechanism, an adhesive spraying mechanism, a curing mechanism and a seedling unloading mechanism. Along the circumferential direction of the transfer mechanism, a seedling loading station, an adhesive spraying station, a curing station and a seedling unloading station are sequentially arranged. The seedling loading mechanism is configured for bearing a rootstock and a scion, and the cutting mechanism is configured for cutting the rootstock and the scion. The transfer mechanism is configured for receiving and fixing the rootstock and the scion, and transporting the rootstock and the scion intermittently from the seedling loading station, the adhesive spraying station, the curing station and the seedling unloading station in turn to obtain a grafted seedling.
