The main results are as follows: 1. The seedlings cultivated by sowing are strong and vigorous, so they are suitable for mass propagation. Generally from July to August, the newly collected seeds will first break the seed coat in order to promote germination, otherwise leaving the soil for a long time will easily cause the seeds to rot, and then sow the treated seeds in the sand bed, covering about 1.5 cm of fine sand. Under the condition of 25-28 ℃ and a certain humidity, it can germinate after about 2-3 weeks, and it can be planted immediately after germination.
