Planting conditions of Rhizoma Polygonatum

Planting polygonatum needs to choose a good area, with damp mountain shrubs and forest edge grass most suitable, dry environment is not conducive to growth. Polygonatum propagation methods are mainly rhizomatous propagation and seed propagation, so it is necessary to distinguish between good propagation techniques.

Cultivation conditions of Polygonatum odoratum

1. Land selection and preparation

Choose moist and fully shaded plots, soil with loose texture, good water retention loam or sandy loam is appropriate.

2. Reproductive methods

1. Rhizome propagation: Select 1-2-year-old healthy plant rhizomes without diseases and insect pests around late autumn or early spring in late March, select young parts at the tip, cut into several sections, each section has 3-4 nodes, dry the wound slightly, plant according to row spacing of 22-24 cm, plant spacing of 10-16 cm, depth of 5 cm, slightly suppress and water after covering the soil, and water once every 3-5 days to keep the soil moist.

(2) Seed propagation: After the seeds mature in August, select mature and plump seeds for sand storage immediately: 1 seed and 3 sand mixed evenly. Store in shady pits 30 cm deep, keep moist. The seeds are screened out in late March of the next year, evenly spread into shallow furrows on the ridge surface according to row spacing of 12-15 cm, covered with soil of about 1.5 cm, watered after slightly pressing, and covered with a layer of grass to keep moisture. Remove the cover grass before emergence, seedling height 6-9 cm, too dense can be appropriate thinning seedlings, transplanted after 1 year.

3. Field management

In the early stage of growth, it is necessary to cultivate and weed frequently, once a year in April, June, September and November, and it is advisable to hoe shallow and cultivate soil properly; in the later stage, weeding can be done. In case of drought or in the more sunny, dry places need timely watering. Every year, top dressing is carried out in combination with intertillage and weeding. After the first three intertillage, 1500 kg of soil miscellaneous fertilizer is applied per mu, 50 kg of calcium superphosphate and 50 kg of cake fertilizer are mixed evenly, and then the soil is covered with fertilizer.
