Softwood cuttings of Ligustrum lucidum
Ligustrum lucidum is a small shrub of Oleaceae Ligustrum lucidum. The primary leaves are golden yellow and the old leaves are green, glossy, adaptable and extensive in management. it is a common tree species in landscaping at present. In this paper, the softwood cutting propagation technique of Ligustrum lucidum is briefly introduced. First, select land preparation plots that are loose and fertile, flat and well drained, apply 125 kg of calcium superphosphate per mu, turn 15 cm deep and then fine rake flat to make a high border 1.2 meters wide and 20 cm deep. Second, the choice of cuttings should first select the mother tree. Generally speaking, the older the tree is, the older the tree is.

Common pests of Ligustrum lucidum and their control
Ligustrum lucidum is a semi-evergreen shrub of the genus Ligustrum lucidum of Oleaceae. Because of its golden shoot, pruning resistance and drought resistance, it is often used to decorate flower beds and green belts with safflower wood, rhododendron, cypress and so on. Often due to the use of high-density planting, insect pests occur more seriously, resulting in slow growth or no new branches, weak growth or even death. The common and seriously harmful pests of Ligustrum lucidum are: pink scale, Ligustrum lucidum, Ostrinia furnacalis. 1 the adults and nymphs of the pink scale lie on the branches and leaves of Ligustrum lucidum, and suck the plant juice with piercing mouthparts.

Control of common diseases and insect pests of Ligustrum lucidum
The common diseases of Ligustrum lucidum are: leaf spot disease, ring disease, coal pollution disease and so on. The main pests are: shell insects, grubs and so on. Brown spot is the most serious leaf spot disease of privet, which is caused by pathogenic fungi. In the early stage of the disease, there are small brown spots on the leaves, with purplish red halos around them, and black mildew can be seen on the spots. As the temperature rises, sometimes several disease spots are connected, and finally the leaves scorch and fall off. The optimum temperature for the growth of the pathogen was 25 ℃ to 30 ℃, and the optimum temperature for spore germination was 1.

Diseases and pests of Ligustrum lucidum
Content: we have a large golden leaf privet every high temperature, high humidity season into a piece of fallen leaves, until withered yellow, ask what is the reason, how to prevent? Reply: may be caused by fungi "golden privet leaf spot disease" plum rain season will be everywhere "chaos", the onset of the golden privet will soon lose its leaves. It is generally caused by the overdense planting density, which has appeared in large numbers in Shanghai in recent years. Prevention and treatment: spraying germicidal pesticides.

The high connection of big leaf privet and golden leaf privet
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). Ligustrum lucidum with breast diameter of 3 cm to 4 cm was used as rootstock.

Control methods of Leaf spot of "Golden Leaf Privet"
There are nearly round brown disease spots on the diseased leaves, often with wheel lines, and the periphery of the edge is often yellow. The initial lesion is small, after expansion, the diameter of the spot is more than 1 cm, and sometimes the spot fuses into an irregular shape. The diseased leaves are very easy to fall off from the branches, resulting in the phenomenon of baldness in the branches of Ligustrum lucidum in the seriously affected area. The first occurrence period is in the first ten days of April, and the peak periods are from July to August and October. From mid-May to mid-August and from mid-September to early November, 47% Meike 3000 × 4000 liquid and 1% bacterioridine 2 are used.

Cutting techniques of "Golden Leaf Privet"
The golden leaf color of Ligustrum lucidum and its pruning resistance make it widely used in landscaping. In order to rapidly propagate Ligustrum lucidum, it is very important to improve the survival rate of its cutting. now we will introduce our cutting experience for many years for your reference. Using new shoots of two-year-old Ligustrum lucidum, it is best to cut the lignified part into cuttings of about 15 cm, remove all the lower leaves, leave 2 to 3 leaves in the upper part, cut flat 1 cm away from the upper bud, and cut the lower cut obliquely into a horseshoe shape on the back of the bud. The cutting substrate was disinfected with coarse sand and 0.5% potassium permanganate solution.

Seedling cutting methods of Metasequoia glyptostroboides
The cutting method of Metasequoia glyptostroboides seedlings: cutting along with cutting from late March to early April. Cut cuttings with 1-2-year-old seedlings or new shoots germinated in the same year. The lower end of the cuttings was treated with naphthalene acetic acid at a concentration of 0.5 ppm and soaked for 20 to 24 hours to promote rooting and survival. About 120 plants per square meter. Keep the nursery bed moist after insertion. The new roots germinated for about 40 days, and rarefied human feces and urine were applied every 10 days for 3 to 5 times. In June, a small amount of nitrogen fertilizer can be applied many times, 3 to 4 kilograms of urea per mu, mixed with water. In the first ten days of August, phosphorus and potash fertilizer were applied once per mu.

What are the characteristics of metasequoia species?
The tree species of Metasequoia glyptostroboides are characterized by deciduous trees of Taxodiaceae. It can reach more than 35 meters in height and 2.5 meters in breast diameter. At the end of the trunk, the base is often inflated and the crown is conical. It is a precious tree species endemic to China. It belongs to ancient relict plants. Metasequoia glyptostroboides is adaptable, but likes warm and humid climate, deep, fertile and moist soil. Drought, barren, low temperature and saline-alkali are not conducive to the growth of metasequoia. Metasequoia wood has straight texture, light and soft material, small difference in shrinkage, and easy to process. Suitable for construction, furniture, agricultural tools, ships and other materials, can also be used as raw materials for papermaking. With
