Propagation method of cherry blossom
Grafting propagation to the main, sowing, cuttage can also be. Grafting generally select cherry, mountain cherry seedlings as rootstock, to fine varieties of cherry as scion. Cut grafting is mainly used, bud grafting is rarely used.
The grafting took place in March. Choose healthy 1-year-old cherry branches as scions, cut into about 8 cm long segments, each with 2-3 full buds. Cut two symmetrical inclined planes of different sizes at the lower end of scion with grafting knife. One side is 2 cm long and 1/3 of the xylem is removed; the other side of the inclined plane is about 1 cm long, a little xylem is cut off to form a wedge shape, and the cut surface should be smooth, which is beneficial to survival. Cut the selected rootstock at a height of 10 cm from the ground, and then select a position consistent with the diameter of the scion at the north side of the rootstock section. Cut a seam from top to bottom with a little xylem between the xylem and the cortex with a cutter, and the depth is about 3 cm. Then insert the scion inclined plane into the rootstock incision. Align the formers (at least on one side). Then tie the joint tightly with plastic tape and protect it with wet soil. Remove the protective layer after scion survives.
