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 is disinfected with coarse sand and 0.5% potassium permanganate solution for one day, and then used for cutting. before cutting, a stick thicker than the cuttings is used to punch holes, and after cutting, the cutting density is not in contact with each other, and the distribution is uniform. Spray water through the plastic film, press half of it tightly with soil, press the rest with bricks for spraying water, and then shade with Reed curtains. Spray water twice a day before rooting, 10 ∶ 00 to 11 ∶ 00 in the morning and 13 ∶ 00 to 14 ∶ 00 in the afternoon to cool and moisturize, keep the temperature in the shed 20 ℃ to 30 ℃ and the relative humidity above 95%. Properly ventilated at noon every day, in order to prevent its decay in summer, 800 times carbendazim was sprayed 3 days after insertion, and again 10 days later. About 21 days after insertion, after 2 days of small ventilation, the plastic film can be removed sooner or later, shaded by Reed curtains at noon, pay attention to spraying more water, and all of them can be removed 3 days later. The seedlings can be transplanted in cloudy days or in the evening after 4 to 5 days, and watered once immediately after planting, and again after 3 days, the survival rate can reach 100%, and a small arch shed is needed to overwinter in winter.
It should be paid special attention that the survival rate of cuttings is closely related to the substrate of cutting, the concentration of rooting powder, the degree of Lignification of cuttings and the time of cutting: the rooting rate of coarse sandy soil is higher than that of fine sandy soil, and the rooting rate of cuttings with 1/1000 solution is higher than that of low concentration. The rooting rate of cuttings with Lignification is higher than that of semi-Lignification, and the rooting rate of cuttings in summer is higher than that in autumn.

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.

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.
