Fertilization technology of privet
The time of fertilization should be in late March of the following spring, remove the sealed soil when applying fertilizer, dig a ring ditch 50 cm away from the tree trunk, 40 cm deep and 30 cm wide, and then apply farm manure. Ligustrum lucidum has low requirements for fertilizer application, more or less. After survival, fertilizers can be applied twice during watering from May to June each year, each time with 50Mel 100g of potassium dihydrogen phosphate or urea.

Control of Ligustrum lucidum
The wing pattern of the adult Ligustrum lucidum is slightly like a basket of woven texture, with a wingspan of about 9-10cm, which is a large moth. The larvae are gray-black or light-colored, and there are two dorsal horns on the 2nd and 3rd segments of the body when young, and the 2nd and 3rd segments are dilated when they are nearly old, and the color around the valve is bright. The larvae can make a cackling sound in their mouth when they are disturbed. Adult Eclosion from June to July. The hosts are privet, lobular wax, Japanese privet, white wax, sweet-scented osmanthus and so on. At present, it is the period of damage to the older larvae, which we are used to seeing. Prevention and control methods:

How to control scale insects in privet hedge
In recent years, with the application of Ligustrum lucidum and Ligustrum lucidum in urban greening, diseases and insect pests on privet have become a major problem in garden maintenance and management. The scale insects occurring on the greening plants of Ligustrum lucidum are mainly white wax scale. It is reported that Kang's pink scale once occurred on the hedge of privet in Hebei Province. The identification characteristics and control measures of white wax scale are introduced as follows: the distribution and damage of white wax scale Ericeruspela (Chavannes) belongs to Homoptera, Coccidae. It is widely distributed in China. For

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 picking it up

The value and use of privet
Garden use Ligustrum lucidum is whirling in four seasons, with sparse branches, dense branches and leaves, and neat tree shape. it is a commonly used ornamental tree species in the garden, which can be planted alone or in clusters in the courtyard, as well as street trees. Because of its strong adaptability, fast growth and resistance to pruning, it is also used as a hedge. Generally, it can be formed after 3 to 4 years to achieve the effect of isolation. It is easy to sow, propagate and raise seedlings, and it can also be used as a rootstock to propagate sweet-scented osmanthus, cloves and colored leaf plant Ligustrum lucidum. Privet leaves for medical use. Privet leaves opposite, leathery, ovate or ovate-lanceolate, long 5~14cm

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

The reproductive technology of privet?
The reproduction technology of privet is to propagate with seeds or cuttings. Select leeward to the sun, fertile soil, convenient drainage and irrigation, thick cultivation layer of loam, sandy loam, light clay as sowing land. After the application of base fertilizer, intensive ploughing and harrowing, so that the upper and lower solid, land leveling. The base fertilizer is mainly manure, and more application is beneficial to improve the soil temperature, maintain the soil moisture and promote the seed to absorb water and start early. In order to prevent underground pests, use 400 to 500 milliliters of 50% phoxim EC (or methyl isofenphos) every 667 square meters, add 3 kg of fine soil, and spread evenly on the surface before turning the ground.

Privet inchworm
Scientific name: NaxaseriariaMotschulsky morphological characteristics: adult wing spread about 40 mm, slender body, yellow-white. The front and rear wings are thin, white and slightly transparent, with two rows of black stellate spots on the outer edge and a large black spot in each wing. The front wing also has a row of black and brown spots near the base angle. The eggs were white at first, then gradually changed to orange-red, shiny and arranged in the shape of beads. The larvae are about 30 mm long, dark brown, with inconspicuous black patterns and spots. Except for the chest foot and the eighth and ninth abdominal feet,
