Propagation methods of Ligustrum lucidum
Ligustrum lucidum belongs to the genus of Oleaceae. Distributed in alpine areas of 1500 meters in Luoxiao Mountains, evergreen shrubs or small trees, 5-7 meters high, twigs and pedicels purplish red, leaves oval, 6-8 cm long, 3-4 cm wide, lavender red. Terminal panicle, 6-8 cm long. Fruit long oval, false berry drupe, a seed. The flowering period is May, the fruiting period is August, and the branches are full of red fruit, which does not fall until October. This variety has strong adaptability, fast growth, high germination rate, pruning resistance, and can withstand the low temperature of minus 20-22 ℃. It can be cultivated in the open field in the area with good microclimate in Beijing, and can resist sulfur dioxide, chlorine and hydrogen oxide. The growth is normal in the alkaline soil with PH value of 8-9.
To breed:
1. Seed propagation: after seed harvest, after 5-7 days of post-ripening period, then wipe off the seed coat, Amoy out the seed in clean water, dry slightly, mix with moist fine sand, sow in December, the northern region can be extended to March, sparse seedlings and transplant in April-May the following year, planted in the field in the second year, and come out of the nursery after 2-3 years.
2. Cutting propagation: divided into spring and summer, spring cutting is carried out in March and summer cutting is carried out from June to July. Cuttings must be lignified, 7-8 cm long, with 1-2 leaves, cut into the shape of Malta, and the bed substrate is mixed with fine loess with 1/3 fine sand. After planting, fully sprinkle water, cover the arch shed with film, and use sunshade net to protect shade.

How does Ligustrum lucidum breed?
The seedling method of Ligustrum lucidum is: wet sand stratification for about 60 days before sowing in early spring. The row spacing is 15 - 20 cm, the seeding rate is 7.5 - 10 kg per 667 m2, the soil cover is 1 - 1.5 cm, and the grass cover is covered. Generally, germination and emergence begin in mid-April. When seedlings are partially out, they are removed and seedlings are thinned in time. Annual seedlings up to 40 to 60 cm, can be taken out of the nursery to do hedges, such as street trees or garden greening, need to be cultivated separately for 2 to 3 years, when the seedlings are 1.5 to 2 meters high, can be transplanted, big seedlings to bring mud balls, and cut off
