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.

The shaping and pruning of privet
1. When transplanting and pruning in the nursery, the trunk should be cut short. Under the cut, only one strong bud can be selected to develop into a trunk extension branch, while the opposite bud must be removed. In order to prevent the formation of apical competitive branches, the first to 2 pairs of buds under the cut should be destroyed at the same time. 2. Before planting and pruning, the one-year-old extended branch of the central trunk of the big seedling should be truncated and truncated, and the strong buds should be left behind. At the same time, one bud in the first pair of buds under the cutting should be removed to ensure the advantage of the bud tip. In order to prevent competition at the top
