After applying base fertilizer, intensive cultivation should be carried out, so that the sky is solid and the land is flat. Manure is the main base fertilizer, and more base fertilizer is beneficial to improve the ground temperature.

2.

Ligustrum lucidum seeds. 1 1~ 12 is ripe, and it is often whitewashed by wax. To harvest in time, choose the tree with strong tree potential, good posture and strong resistance as the mother tree.

4.

Winter sowing is carried out before freezing, and generally there is no need to accelerate germination. After thawing, spring sowing can accelerate germination significantly. In order to break the dormancy of Ligustrum lucidum seeds, the seeds were soaked in 550mg/kg gibberellin solution for 48 hours before sowing, and the water was changed 65438 0 times a day, and then they were taken out and dried. After standing for 3 ~ 5 days, soak at 25~30℃ to accelerate germination, and pay attention to changing water every day.

5.

Sowing and seedling raising are carried out from the first half of March to April. Before sowing, the peeled seeds were soaked in warm water 1 day, the row spacing was 20cm, the covering thickness was 1.5~2.0cm, and the sowing amount was about 105kg/hm2.
