First, the grafting time
It is generally conducted from early July to late September. The grafting time is too early, the sprouting development is not substantial, and the degree of lignification of the scion is low. When the grafting time is too late, the interface will heal slowly and the survival rate will be low.
Second, before the preparation
1, stock selection
Select wild jujube seedlings that grow robustly, have no pests, and have a base stem above 0.5 cm as rootstock.
2, scion acquisition
Cut spruce growing, pest-free, bud-filled, and lignified branches of the year as scions, with a diameter of 0.4-0.6 cm, and leaves to be removed to leave the petiole.
3, scion preservation
In order to facilitate storage and transportation, the scion can be cut into small pieces of 20 to 30 cm long, buried with wet sand or moistened with wet sacks, and timely watered.
Third, grafting method
Use budding method with rootstock: First select the bud on the rootstock and cut it horizontally to a depth of xylem, then cut a "T"-shaped interface 1.5 to 2cm long from top to bottom; 0.5cm above the full bud of the scion Cross-cut a knife, deep wood 1 ~ 1.5 cm, with a knife from the bottom up quickly cut buds, a little shorter than the length of the rootstock on the interface, will be attached buds in the rootstock "T" shaped interface, so that the bud The forming layer is aligned with the forming layer of the rootstock (the top is aligned with one side) and tied with a 0.5 cm wide plastic strip.
Fourth, after the management
15-20 days after grafting, check whether it survives or not. Surviving seedlings were cut into anvils at 2 to 2.5 cm above the shoots in the spring of the following year, and plastic strips were removed to promote the survival and germination of the grafted shoots.
