1. Bud grafting method: every 5-9 days, select full buds on the improved mother plant and cut them off, and graft 1-2 buds on the Tang white jade or rose rootstock, or graft a bud every 8- 10 cm on the long branch of the rootstock, and cut off branches with live buds in sections after grafting.
2. Branch grafting method: Cutting, tongue grafting, abdomen grafting and other methods can be used to graft the branches of improved varieties on the rootstocks of Rose and Tang Baiyu every spring.
3. Rooting method: In winter and spring, when the rose is dormant, insert the scion on on one of the indoor roses or Tang Baiyu, tie it, put it at the bottom, keep it moist in a medium-temperature greenhouse, and plant it in a flowerpot or field after its interface heals.
