Embodiment Construction

[0012] The invention discloses a method for cultivating large seedlings of elm elm, which uses large-sized white elm trees with a breast height of 15 cm or more as rootstocks, and annual branches of elm elm as scions for grafting.

[0013] Its specific technological process is as follows:

[0014] Grafting time: It should be carried out in the first and middle ten days of March, and it is most suitable when the sap will start to flow before the rootstock germinates.

[0015] Selection and preparation of the scion: choose 1-year-old, strong, full-bodied, and free of disease and insect pests of golden leaf elm branches as the scion, cut the middle section of the branch about 8-10 cm, and cut the lower end into a 3-5 cm slope with a thickness of 0.3-0.5 cm. Cut a small slope of 0.5-0.8 cm, and keep 2-3 buds on the scion after cutting, and the scion should be picked as it is picked.

[0016] Grafting method: take the grafting method: choose white elm with a diameter of 15-20 cm, ...
