seed propagation
After the seeds mature in August, select the mature and plump seeds for immediate sand storage treatment: 1 part of the seed and 3 parts of sand are mixed evenly. Store in a 30 cm deep pit in the shade and keep moist. When the seeds are screened out in late March of the second year, they are evenly sown in the shallow ditch on the border surface according to the row spacing of 12-15 cm, covered with soil about 1.5 cm, watered after a little pressure, and covered with a layer of grass to keep moisture. Remove the cover grass before emergence. When the seedling height is 6-9 cm, the seedlings can be properly thinned in the dense place, and transplanted after 1 year. In order to meet the shade conditions required for the growth of Polygonatum chinensis, corn can be grown on the ridge.
