Seed propagation
After the seeds mature in August, select mature and full seeds and immediately carry out sand storage treatment: mix 1 seeds and 3 grains of sand evenly. Store in a pit 30 cm deep in the shade and keep it moist.
When the seeds were screened out in late March of the following year, they were evenly sown in the shallow furrow on the border according to the row spacing of 12~ 15 cm, covered with soil about 1.5 cm, watered slightly, and covered with a layer of grass to keep moisture.
Remove the mulch before emergence. When the height of seedlings is 6~9 cm, the seedlings can be properly thinned in the over-dense place, and transplanted after 1 year. In order to meet the shading conditions of Polygonatum sibiricum growth, corn can be planted on the ridge of the field.
