1. Planting conditions

1. Soil: Polygonatum prefers a moist and shaded environment. When cultivated artificially, sandy loam or loam with good water retention and loose soil should be selected.

2. Light: Polygonatum sibiricum prefers shade and should be planted under forests, in bushes or in the shade of hillsides to avoid prolonged direct sunlight.

3. Watering: Keep the soil moist and avoid waterlogging. Water every 3-5 days on sunny days and pay attention to drainage on rainy days.

4. Fertilization: Apply sufficient base fertilizer before planting, about 2,000 kg per mu. During the growing season, top dressing should be carried out 3-4 times. Apply 1500 kg of soil fertilizer, 50 kg of superphosphate and 50 kg of cake fertilizer per mu. After evenly mixing, apply it into the furrows between the rows and cover with soil.

2. Planting Method

1. Soil preparation: Deeply plow the soil, keep it loose, and apply base fertilizer, mainly organic fertilizer or farmyard manure, about 2,000 kilograms per mu. Avoid applying uncomposted fertilizer to prevent damage to seedlings.

2. Reproduction method:

Seed propagation: store seeds in sand in August and sow in March of the following year. Dig shallow furrows on the bed surface with a row spacing of about 15 cm, sow seeds, cover with a thin layer of soil, water thoroughly, and cover with grass. After one year of cultivation, transplant and plant.

Rhizome propagation: Select the rhizome of a mature Polygonatum sibiricum plant, cut off the tender parts, dry the wounds and then plant them, keeping the soil moist.

3. Intertillage and Weeding

Weeding: Start weeding after the seedlings emerge from the soil, 3-4 times a year to prevent nutrient loss and ensure normal growth of the seedlings.

Intertillage: Appropriate intertillage should be performed during the seedling growth stage to keep the soil loose and avoid compaction. Pay special attention during rainy seasons to avoid affecting root respiration. After the seedling stage, inter-cultivation should be carried out in combination with soil cultivation to prevent lodging.

4. Post-management

1. Watering: Water once a week after transplanting, and provide shade in time when there is strong light to protect the plant.

2. Fertilization: Fertilize in conjunction with weeding. Apply after the first weeding and then once every 1-2 months. Control the concentration and amount of fertilizer to avoid burning the roots.

3. Pest and disease control: Pay attention to underground pests during the seedling stage and prevent and control them in time to avoid affecting plant growth.

The above are the key points of Polygonatum sibiricum cultivation. Through the above meticulous planting management and technical points, the yield and quality of Polygonatum sibiricum can be effectively improved to meet market demand and bring good economic benefits to growers.
