What are the propagation techniques for glossy privet? A detailed explanation of the methods

The propagation techniques for glossy privet are: reproduce by seed, or by cuttings. Choose a sowing site that is sheltered from the wind and sunny, with fertile soil, convenient drainage and irrigation, and a thick plough layer, such as loam, sandy loam, or light clay. After applying base fertilizer, plough finely and harrow thoroughly, so that the topsoil is loose and the subsoil is firm, and the land is level. The base fertilizer is mainly manure; applying more helps raise soil temperature, maintain soil moisture, and prompt the seeds to absorb water and sprout early. To prevent underground pests, use 400 to 500 ml of 50% phoxim emulsifiable concentrate (or isofenphos-methyl) per 667 sq m, mix evenly with 3 kg of fine soil, and spread it evenly on the surface before ploughing, then bury it into the soil when preparing the land, and the bed surface must be level. In North China, the seed collection period is from late November to mid-December; choose trees with strong vigour, good form, and strong resistance as mother trees for seed collection. Do this on a sunny afternoon, select seeds with high maturity, plump grains, and no pests or diseases; after collecting, dry them in a cool, ventilated place in the shade, and avoid direct sunlight. For winter sowing, do it before the soil freezes, and generally no pre-sprouting is needed. For spring sowing, do it after the soil thaws, and pre-sprouting gives a notable effect. To break the dormancy of glossy privet seeds, before sowing first soak the seeds in a 550 ppm gibberellin solution for 48 hours, changing the water once a day, then take them out and dry them. After leaving them for 3 to 5 days, place them under conditions of 25°C to 30°C and soak them to promote sprouting for 10 to 15 days, and be sure to change the water every day. The sowing method is mainly broadcasting; the sowing rate is 100 to 200 kg per mu. For drilling, the sowing rate is 20 to 50 kg per mu, with a row spacing of 20 to 30 cm, and a furrow depth of about 0.5 cm, just enough to cover the seeds. Spread the seeds evenly into the furrows, then cover the sowing furrows with 1 cm of fine soil and firm it, and on top add 1 to 2 cm of wheat bran or sawdust to help conserve moisture. After sowing, water thoroughly, preferably by sprinkler or drip irrigation; when flooding irrigation is used, prevent the mulch and seeds from being washed away. Thereafter, irrigation depends on soil moisture.
