Taking different varieties of wintersweet (Chmonanthus praecox) as test materials, the influence of different grafting times, stock ages, and scion positions on the survival percentage of wintersweet grafting were studied, in order to study the key techniques of wintersweet grafting in autumn and winter. The results showed that, in autumn and winter, the grafting survival percentage of wintersweet in late-september was significantly higher than that of mid-october, late-october, and mid-november；with the passage of time, the survival percentage of wintersweet grafting showed a gradual downward trend；there is no obvious regularity of the effect of the different scion positions on the survival percentage of wintersweet grafting in autumn and winter；the survival percentage of grafting with perennial seedlings as rootstocks (56.03%) was significantly higher than that of annual seedlings (21.14%). This research provides technical guidance for the production, reproduction, introduction and expanding of wintersweet in autumn and winter.
