Sowing method of Rhizoma Polygonatum

1. Seed treatment: Rhizoma Polygonatum selected mature and full seeds for sand storage treatment immediately after the seeds matured in August. 1 part of the seed and 3 parts of sand were evenly mixed and stored in a pit 30 cm deep in the shade to keep moist.

2. Sowing at the right time: Polygonatum usually sift out the seeds in late March, spread them evenly into the shallow ditch on the border surface according to the row spacing of 12-15 cm, cover soil about 1.5 cm, water slightly, and cover with a layer of grass to moisturize.

3. Management at seedling stage: the cover grass was removed before emergence of Polygonatum polygonatum. When the seedling height was 6-9 cm, the seedlings could be planted properly and transplant one year later. In order to meet the shade conditions needed for the growth of Polygonatum, corn could be planted on the ridge.

Planting method of Rhizoma Polygonatum

1. Soil preparation and fertilization: Polygonatum polygonatum planting chooses moist and fully shaded plots, and the soil should be loam or sandy loam with loose and good water retention. Turn deeply before sowing, combined with 2000 kg of farm manure per mu of land preparation, and then rake fine leveling to make the border, the width of the border is 1.2m.
