The method of grafting golden leaf privet.

Ligustrum lucidum is generally made into a ball on the ground. In order to improve the ornamental quality, the ball can be raised by means of grafting. Through the experiment, the author used Ligustrum lucidum as rootstock successfully.

Grafting time: grafting was carried out before the cooler weather in autumn and the advent of the second growing season.

Material selection and grafting: strong high-stem and large-leaf privet plants without diseases and insect pests were selected, and 4-5 branches were selected as rootstocks. On the thicker branches of Ligustrum lucidum without diseases and insect pests, well-developed and full bud eyes were selected as buds. Adopt shield grafting method with xylem budding. After being connected, wrap the whole wound layer by layer with plastic film to prevent infection. Generally, each plant of Ligustrum lucidum was grafted with 810 buds.

Management: after the completion of grafting, normal management, about a month or so the wound began to heal. After the spring water was watered at the beginning of April of the following year, the entangled plastic film was removed and the branches of Ligustrum lucidum were cut off at 2 cm on the grafting bud. A few days later, the surviving buds of Ligustrum lucidum began to germinate. when the branches grew to about 10 centimeters, hit the first 2-3 centimeters of the branches.

Ligustrum lucidum and Ligustrum lucidum both belong to Oleaceae and Ligustrum lucidum. The former is a good green sub-tree, which is often ignored because of its universality. The latter is a color tree species, which has been widely used by people in recent years. Because the golden leaf privet belongs to the shrub class, which limits its practicability. In order to expand the greening function of the two, the author makes a high connection by learning from each other to achieve this goal. The steps are as follows:

Branch grafting or budding can be used in spring (sap has flowed, it is best before sprouting). The large-leaf privet with a breast diameter of 3 cm to 4 cm was used as the rootstock and the golden leaf privet as the scion. First of all, choose the height of the rootstock and the angle of the branches. On the inside of the base of the rootstock branch, use a sharp knife to cut a knife about 2 cm long, the blade just reaching the xylem is the best. The scion can be 3 cm to 5 cm long and cut into a positive wedge of about 2 cm with a knife. The blade of the rootstock is slightly longer than that of the scion. Then, quickly and accurately align the cambium of the two. If the blade of the rootstock is too wide, two scions can be juxtaposed. Then, use a moderately thick and flexible plastic strip to wrap up from the lower part of the edge of the rootstock. You can use more force when wrapping the joint of the two, and when you get to the upper part of the scion without a knife edge, you can wrap it around the rootstock. At this time, must wrap the scion tightly, otherwise the scion is easy to air-dry or not completely healed. After grafting, some branches and leaves of the rootstock can be thinned properly, and this work can also be done before grafting.

Spring bud grafting, use a knife to cut a 2 cm long knife in the appropriate position of the rootstock, take a certain amount of xylem (not too thick) when cutting the scion, then aim at the cambium of the two, and wrap it up from the bottom with a plastic strip. When you get to the bud point, you can use a little more effort so as not to hurt the bud. Whether the bud is dewy or not depends on the weather.

You can know whether you will survive or not in a week or so. If the failure can be repeated, if the grafting is successful, you can take off the plastic strip and then wrap it gently. The branch grafting can not wrap around the upper part, and the bud grafting can reveal the bud point to facilitate germination. Before the scion sprouts, do not cut off all the branches and leaves of the rootstock, otherwise it will cause the rootstock to "sprout" or even die. At this time, the branches and leaves of the rootstock can be left with 1 stroke and 3 strong points to facilitate the crown and root system to maintain physiological balance. When the buds of the scion grow to 1 cm to 2 cm, all the branches of the rootstock can be cut off and the plastic strips can be removed. In the future management, the main thing is to remove the sprouts from the rootstocks. Some of the sprouts on the stem of the rootstock can be left behind to control its growth and lay the foundation for future modeling. The sprouts around the roots and scions should be removed so as not to compete for nutrition and disturb the tree.

The affinity of the two is strong, the knife edge heals well, and the grafted seedlings grow vigorously. If the water and fertilizer keep up and manage properly, the crown diameter in two years can reach about 2 meters, and the golden branches will droop naturally. The branches germinated from the middle and lower parts of the rootstock can be artificially shaped, or flat, or spherical.
