1. Seed collection: Ligustrum lucidum blossoms from April to May, and matures from November to December. The skin is black when it is young. The fruit should be harvested at the right time. The ears can be cut with high branches and the fruit can be swabbed, rinsed and dried. If it is not sown immediately, it can be bagged or dried or mixed with 2 wet sand and 1 seeds.
2, seedling: Ligustrum lucidum can be harvested and cuttage in two ways, and seeding and seedling raising is more common.
1. sowing and raising seedlings from early March to mid April. The soil in the nursery is not strict, so long as it is loose and fertile. Before harvest, peel the seeds, soaking them in warm water for 1 days to 2 days, then harvest, drill or broadcast. The drill spacing is 20 cm, covering 1.5 cm to 2 cm, and the yield per mu is about 7 kg. Because Ligustrum lucidum has a longer emergence time, it takes about 1 months. The seedlings should be loosened and weeded in time after unearthing. When the seedlings are 5 centimeters high, the seedlings are afraid of waterlogging. Drainage should be paid attention to, but water should also be irrigated when drought is excessive, and fertilizer should be applied 12 times according to the routine management. Weed 1 times a month. The seedling height of 1 years old can reach 50 centimeters. If the seedlings are grown, they need to be planted in bed for 2 to 4 years.
2. Cutting seedlings can be cut in November and buried in the branches growing in spring. The cuttings are taken out in February and March of the following year. The cuttings are 0.3 cm to 0.4 cm in diameter and about 1518 cm in length per spike. The upper end is flat, the lower end is oblique, and the upper leaves are 12 pieces. The cuttings are inserted into the soil 2/3 plants are 10 cm apart, and rooted about 2 months after the cuttings. M.
