After halliana grafting management (1) to unbundle and then pick up about 10 d after careful to check the survival situation, all the buds fresh or hand touched Bud petiole namely shedding, indicating bud has healed survived. On the contrary, all shriveled buds or petioles Bud touched on those who do not fall, indicating that bud did not survive, need immediate pick up. Solutions can survive after bud tied, generally 15 ~ 20 d solution followed tie. (2) In addition to post-emergence anvil shears unbundling will bud more timely stock portion cut off, from the bud must notches above 0.5 ~ 1 cm, a little tendency to bud across North America crabapple tree, notches to facilitate healing.
