Embodiment 1

[0027] Silk cotton wood grafted Hokkaido boxwood:

[0028] 1. After the selected silk cotton wood with a DBH of 3.5 cm or more is planted and survived, cut it horizontally from 1 to 2.5 meters above the ground, smooth the saw edge, and then cut down a 7 to 8 cm long tree along the stem down to the xylem. incision;

[0029] 2. Select two tillers with 2 to 4 full buds or germinated within 10 cm from the Hokkaido boxwood as scions, and cut the lower end to a slope that is 6 to 7 cm beyond the pith center, and then cut the scion on the back of the scion. Cut into a 0.5cm-long slope, the base of the interface is in the shape of a wooden wedge, and cut a knife on each side, reaching the depth of the phloem;

[0030] 3. Pick up the bark on both sides of the rootstock incision, stick the long cut surface of the scion close to the xylem of the rootstock, insert it straight into the rootstock along the incision, and make the cut edge of the scion exposed by 0.2 cm, tie the joint tightl...

Embodiment 2

[0036] Silk cotton wood grafted Hokkaido boxwood:

[0037] After the silk cotton wood is planted and survived, cut it horizontally from 1 to 2.5 meters above the ground, flatten the saw edge, and then cut a 7 to 8 cm deep cut along the stem down the xylem. ~30 centimeters place is cut into T-shaped incision, is used for grafting scion, and other process embodiment 1.

Embodiment 3

[0039] Silk Cotton Grafting Glue Dongwei Mao:

[0040] After the silk cotton wood with a DBH of 3.5 meters or more was planted and survived, Jiaodongwei Mao was grafted at different heights of more than 1 meter. The specific grafting process was the same as in Example 1.

Abstract

The present invention is the cultivation technique of cold resistant Hokkaido box or Jiaodong spindle tree, and is the grafting technique with silk cotton tree as stock and Hokkaido box or Jiaodong spindle tree as scion. Through grafting of silk cotton tree with early germination, late leaf falling and high cold resistance and Hokkaido box or Jiaodong spindle tree in the same genera to form one new kind of landscape tree with improved cold tolerance and fast growth speed.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for cultivating cold-resistant Hokkaido boxwood and Jiaodong weimao. Background technique [0002] Hokkaido boxwood and Jiaodong wei Mao belong to the family of wei mao and genus wei mao. They are cold-resistant and humid. They are evergreen broad-leaved tree species and are commonly used landscape tree species in urban greening. However, the seedlings (0-3 years) of Hokkaido Buxus and Jiaodong Weimao cannot survive the winter normally under the natural climate conditions in the north, and the parts above the rhizomes are easy to dry out if no protective measures are taken. Trunks and spherical shapes cannot be formed. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art, and to provide a grafting technique, which can further improve the cold resistance and growth rate of Hokkaido...
