The grafting propagation technology of Sapinous saroraria was studied to provide improved seedlings for production.The branches of Sapinous saroraria were used as experimental materials,and three grafting methods,six grafting time and four rootstock ground diameter sizes were applied in grafting experiments.The results showed that the grafting survival rate with different grafting propagation methods was significantly different(P＜0.05),and the grafting survival rate with the cutting grafting method was the highest(86.7％).The grafting survival rate of the cutting grafting method was significantly different at different grafting time(P＜0.01),and the grafting survival rate was the highest in mid-March.There was a significant difference in the grafting survival rate by using the cutting grafting method with different diameter sizes of the rootstock(P＜0.05),and the grafting survival rate was the highest when the diameter of the rootstock was 1.0～2.0 cm(88.4％).The grafting survival rate of Sapinous saroraria seedlings is affected by many factors,and the synergistic effect of multi-factor combination is helpful to improve the grafting survival rate of Sapinous saroraria.
