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, every 667 square meters with 50% phoxim EC (or methyl isofenphos) 400 to 500 ml, add fine soil 3 kg to mix well, before turning the ground evenly scattered on the surface, buried in the soil during soil preparation, the bed should be flat. The seed collection period is from late November to mid-December in North China, and the trees with strong strength, good posture and strong resistance are selected as the mother trees. In the afternoon on a sunny day, select seeds with high maturity, full seeds, disease-free and insect-free seeds, and dry them in a cool and ventilated place to avoid sun exposure. Winter sowing is generally not needed to sprout before freezing. After the spring sowing was thawed, the sprouting effect was significant. In order to break the dormancy of privet seeds, soak the seeds with 550 parts per million gibberellin solution for 48 hours before sowing, change the water once a day, and then take it out to dry. Place it for 3 to 5 days, and then put it under the condition of 25 degrees Celsius to 30 degrees Celsius for 10 to 15 days. Be sure to change water every day. The sowing method is mainly sowing, and the sowing amount per mu is 100 to 200 kg. Such as strip sowing per mu of 20 to 50 kg, row spacing of 20 to 30 cm, trench depth of about 0.5 cm, it is appropriate to bury the seeds. Spread the seeds evenly into the ditch, then cover the ditch with 1 cm thick fine soil and cover it with 1 to 2 cm thick wheat bran or sawdust to preserve moisture. Watering thoroughly after sowing, it is better to sprinkle irrigation and drip irrigation to prevent the mulch and seeds from being washed away during flood irrigation. Irrigation depends on soil moisture in the future.
