Example Embodiment

[0012] A method for cultivating large seedlings of the golden leaf elm. The large-size white elm trees with a diameter of 15 cm or more are used as the rootstock, and the annual branches of the golden leaf elm are used as scions for grafting.

[0013] The specific process is as follows:

[0014] Grafting time: It should be carried out in early and mid-March, when the sap will begin to flow before the rootstock germinates.

[0015] Scion selection and preparation: Choose 1-year-old elm branches with strong, full side buds and no pests and diseases as scions, cut the middle section of the branches about 8-10cm, and cut the lower end to grow a slope of 3-5cm, 0.3-0.5cm thick, and the back end Cut a small slope of 0.5~0.8cm. After cutting, 2~3 buds should remain on the scion, and the scion should be picked as soon as it is picked.

[0016] Grafting method: adopt the bark grafting method: choose a white elm tree with a diameter of 15-20cm and a height of 2.5-3 meters, which is strong and d...

Abstract

The invention relates to the technical field of grafting for optimization of plant varieties, in particular to a cultivation method of big ulmus pumila cv.jinye seedlings. The method comprises the steps of using large-size white elm with diameter at breast height over 15cm as rootstock and using annual branches of the ulmus pumila cv.jinye as scion, and grafting. The method quickens the propagation speed of the ulmus pumila cv.jinye and provides a new excellent colour-leafed plant variety with strong adaptability, high resistance, golden leaves and bright colour.

Description

technical field [0001] The invention relates to the technical field of plant variety optimization grafting, in particular to a method for cultivating large seedlings of elm elm. Background technique [0002] Golden leaf elm is a variety of white elm, with golden leaves and bright color; its branches have strong germination ability, denser branches, fuller canopy and richer shape than white elm; it is stronger in cold resistance, drought resistance and salt-alkaline resistance than white elm, but at present Large-scale elm trees have not been seen in the market yet, and conventional cultivation measures are difficult to meet the market demand for large seedlings of elm. Contents of the invention [0003] In order to overcome the deficiencies of the existing technology, the invention provides a method for cultivating large seedlings of Ulmus japonica. [0004] The technical scheme adopted by the present invention to solve the technical problem is: a method for cultivating l...
