Grafting Technology and maintenance Management of Ligustrum lucidum

The ornamental value of Ligustrum lucidum is mainly reflected in its tree type, which is a kind of malleable and very resistant tree species. The survival rate of Ligustrum lucidum propagated by grafting is relatively higher.

Grafting technique of Ligustrum lucidum

First of all, choose the height of the rootstock and the angle of the branches. On the inside of the base of the branch of the rootstock, use a sharp knife to cut a knife about 2 meters long, the blade just reaching the xylem is the best. The scion can be 3 to 5 meters long and cut into a positive wedge of about 2 meters 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, the scion must be tightly wrapped, otherwise the scion is easy to air-dry or incomplete healing. 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 in the appropriate position of the rootstock to cut a knife about 2 meters long, when cutting the scion with a certain amount of xylem (not too thick), and then aim at the cambium of the two, 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.

Maintenance and management of Ligustrum lucidum

1. Ligustrum lucidum is a wet plant, but excessive water can easily lead to disease, so it is necessary to strictly control water and spray water every day to meet the needs of the growing environment of privet. Spray water can be carried out by sprinkler irrigation facilities, which can ensure the area of water distribution, maintain ground humidity, and reasonably control the amount of water. The best time to spray water is from 8 to 10:00 in the morning, or from 4 to 6 in the afternoon, and the amount of water should be about one to two hours at a time.

2. Ligustrum lucidum likes fertilizer. Before planting, fermented circle fertilizer is applied as base fertilizer. In March, combined with thawing water, ring ditches are dug around the tree 50 meters away from the trunk, and a certain amount of farm fertilizer is applied. 50-100 grams of nitrogen fertilizer is applied in the middle of May, and at the end of November, a small amount of semi-rotten ring fertilizer can be applied in combination with frozen water.

3. When the light is particularly strong, we should open the sunshade net to avoid high temperature caused by strong light and affect the growth rate of seedlings. After 4 o'clock in the afternoon, the sunshade net should be folded up when the light is weak. But it should be noted that sunshade nets, like a shade awning, can bring plants a comfortable environment, if there is no sunshade net, they can still grow safely and healthily.

4. The purpose of shaping and pruning of Ligustrum lucidum is to maintain a perfect and plump tree shape. First of all, remove the dense branches, dry and withered branches and sick and weak branches in the crown. Then, according to the growth direction of the side branches, the needed side branches are retained, and the unneeded side branches are determined or removed according to the crown shape of the tree.

5. The common pests of Ligustrum lucidum are spotted wax cicada, APHIS gossypii, pomegranate felt scale and so on. For the occurrence of privet leaf woolly aphid, 10% imidacloprid wettable powder or Kushen soluble liquid was sprayed on the plant in the first ten days of April; pomegranate felt scale occurred, and highly permeable agents such as 2000 Guoguangbizhi diluted to 1000 times were sprayed, focusing on the location where the insect insect occurred in order to spray wet without dripping water.

6. There are two parts of weeding at the seedling stage, one is to remove the weeds in the nutrition sheet manually, and the other is to remove the weeds on the inland cloth of the operation road with drugs.

In addition to being used in landscaping, Ligustrum lucidum can also be used for pot culture, but pot culture needs to be pruned at the right time, because we need to prevent it from becoming too big and messy or growing flowerpots.
