Advantages of grafting propagation of Cornus officinalis

Cornus officinalis is planted and propagated for a long time. The bred seedlings can bear fruit more than 10 years after planting, while the grafted seedlings can blossom and bear fruit in 2 ~ 3 years. The method of grafting propagation can make Cornus officinalis bear fruit early and benefit early

Rootstock and grafting time of Cornus officinalis

Generally, the rootstock of Cornus officinalis in grafting is the seedling of its own improved seed. Grafted scions should be taken from high-quality mother trees with high yield, strong growth and no diseases and pests

Generally, around the middle and late March, dogwood is grafted with cuttings. From mid July to mid August, Cornus officinalis is generally budding

Grafting method of Cornus officinalis

The skin grafting of Cornus officinalis is mainly to cut off the part of the Cornus officinalis plant close to the ground 5-10cm, flatten the section, cut it from top to bottom with a grafting knife on the windward side to reach the xylem, and then pry a crack in the cortex of the interface with a knife. Cut the scion into a section of 15cm long, cut an oblique section of 3 ~ 5cm long on the lower side of the back of the main bud to expose the cambium, and put the cut scion into the inlet for moisturizing. Next, lean the slope of the scion inward, with the tip facing the cutting seam, press the cutting edge of the rootstock tightly by hand to insert the scion slowly, then tap the interface with the grafting knife to fasten it, and finally bind the interface with plastic film. When the scion seedlings grow to 50cm high, cut the plastic film with a knife

The budding of Cornus officinalis is to first select mature and robust scions and remove tender buds. Use a knife to carve a piece of bark 10 ~ 5 cm away from the ground. Insert the bud block to be connected into the peeling part of the rootstock, and then bind it tightly with plastic film, but expose the bud. After 7 ~ 10 days of grafting, the interface heals, the bandage can be untied, and the trunk can be cut off 5cm above the bud
