The method of privet to graft gold leaf privet

The golden privet is typically grown as a ground-covering shrub. To enhance its ornamental value, the author experimented with raising the crown through grafting. Using large-leaf privet as the rootstock proved successful in this process. Grafting is best performed in autumn, when temperatures are cooler and before the next growing season begins. For the grafting process, healthy and disease-free high-growing Ligustrum lucidum plants are selected as the rootstock, with 4 to 5 shoots chosen per plant. From the golden leaf privet, strong, pest-free branches with well-developed buds are selected for the scion. A shield graft is used, incorporating the xylem. After the graft is made, the entire wound is wrapped with plastic film to prevent infection. Typically, each rootstock receives 8 to 10 grafts. After grafting, regular care is essential. Within about a month, the wounds begin to heal. At the start of spring, water is applied, and the mulch film is removed. The branches of the privet are cut 2 cm above the grafted area. A few days later, viable buds from the Ligustrum lucidum begin to sprout. When these shoots reach about 10 cm in length, they are trimmed back by 2 to 3 cm to encourage growth. Ligustrum lucidum and golden leaf privet both belong to the Oleaceae family. While Ligustrum lucidum is a popular choice for greenery, it's often overlooked due to its common use. Golden leaf privet, on the other hand, is a colorful shrub that has gained popularity in recent years. However, its shrub-like form limits its broader application. To expand the greening potential of both species, the author successfully combined their strengths through grafting. In spring, when sap flow begins and before leaves emerge, branches or buds can be used for grafting. A rootstock of large-leaf privet with a diameter of 3–4 cm is selected, and golden leaf privet is used as the scion. First, choose an appropriate height and angle on the rootstock branch. On the inner side of the branch base, make a 2 cm long cut with a knife, ensuring the cut reaches the xylem. The scion should be 3–5 cm long and cut into a 2 cm wedge. The rootstock cut should be slightly longer than the scion. Align the two cuts carefully, and if the rootstock is too wide, two scions can be placed side by side. Wrap the graft union from the bottom up using a stretchable plastic strip. Apply firm pressure at the joint but wrap gently around the top of the scion. Ensure the scion is tightly secured to prevent drying or failure to heal. After grafting, some rootstock branches and leaves may be pruned, which can also be done prior to grafting. In spring, shoot grafting is carried out. Make a 2 cm long cut on the rootstock in the desired location. When preparing the scion, include a small portion of the xylem (not too thick). Align the two surfaces and wrap from the bottom up with plastic tape. When wrapping around the buds, use light pressure to avoid damage. Whether to water depends on the weather conditions. Within a week or so, you can determine if the graft was successful. If not, you can try again. Remove the plastic strips and gently re-wrap if needed. Avoid entangling the upper part of the scion, and expose the buds to promote germination. Before the scion sprouts, do not remove all the branches and leaves of the rootstock, as this could cause the rootstock to "stagnate" or even die. Leave about one-third of the rootstock’s foliage to maintain balance between the root system and the canopy. Once the scion’s buds grow to 1–2 cm, the rootstock branches can be completely removed, and the plastic strips taken off. In later management, any new growth on the rootstock should be removed. Some buds on the rootstock stem can be left to control growth through pruning, helping shape the future form. Buds near the roots and scion should also be removed to prevent competition for nutrients and to maintain a clean tree structure. The compatibility between the two species is strong, and the graft union heals well, resulting in healthy seedlings. With proper watering and fertilization, after two years, the crown can reach up to 2 meters, with golden branches naturally drooping. Shoots growing from the lower part of the rootstock can be shaped manually, forming flat or spherical forms.

Its freezing point is about -2.8℃, specific gravity is about 1.04/cm3 and decomposition temperature is 280-300℃. It`s polymeride AKD maturing agent of high charge density. Emulsion provides strong cationic component promotive and protective agent and promotes curing effect. This product is added directly into the synthesis process of intermediates or added a certain ratio in emulsion. This product can be added more in the papermaking system with heavier anionic trash, as the pulp potential equilibrium to play a dual role of sizing enhancement and forcing ripening.

III. Quality indicators;

Appearance: colorless to faint yellow thick liquid Solid content: 40±1%

PH value: 4.0~7.0 viscosity (mpa.s, 25℃): 7000-12000

IV. Application:

This product is applied in alkaline sizing system of AKD (Alkyl Ketene Dimer) to restrict largely the hydrolysis and migration aptitude of AKD. [The third generation" AKD is mainly used for the making of multipurpose duplicating paper filled by precipitated calcium carbonate. 60% cationic polymer can adhere to the fiber after the paper containing cationic polymer being reused, by which enhance hydrophobicity of the paper. Added to waste paper deinking agent, its cationic hydrophilic group adheres to ink particles easily, especially for hydrophobic aniline ink. After flotation, the whiteness of pulp increased. This product is also applied as cationic surfactant in pitch control agent for pulping.
