Study on Grafting Technology of Armeniaca sibirica var. pleniflora

In order to promote the development of asexual propagation technology of Armeniaca sibirica and improve its excellent ornamental characteristics, Armeniaca sibirica grafting experiments were carried out with annual branches of Armeniaca sibirica as scions and five-year-old Prunus armeniaca as rootstocks to study the effects of different grafting methods and grafting time on the grafting survival rate, preservation rate, new branch length and new branch diameter of Armeniaca sibirica.The results showed that the preservation rates of Armeniaca sibirica grafted on annual Prunus armeniaca by abdominal grafting and split grafting were 87.40% and 80.80% respectively.It has extremely significant difference between them.Abdominal grafting was more suitable for Armeniaca sibirica grafted on annual Prunus armeniaca; In the first ten days of April, Armeniaca sibirica was grafted on high branches of five-year-old Prunus armeniaca by budding with xylem, and the graft survival rate, preservation rate, new branch length and new branch diameter were 91.25%,89.17%,152.02 cm and 2.48 cm respectively, the grafting effect was the best.
