Polygonatum sibiricum is a traditional Chinese medicinal material . As its market demand increases, its price is also rising, and its planting prospects are good. Polygonatum sibiricum likes to grow in a moist and hidden environment. Below, the editor will introduce the planting methods and conditions of Polygonatum sibiricum. Let’s take a look.

1. Planting conditions

1. Soil conditions

Polygonatum likes to grow in soil that is deep, loose, breathable, well-drained and rich in organic matter. The soil pH should be between 6.0-7.5, with neutral or slightly acidic soil being preferred.

2. Climate conditions

Polygonatum sibiricum prefers a warm and humid climate, and the suitable growth temperature is 20-30℃. During the planting process, care should be taken to avoid the effects of high and low temperatures on the growth of Polygonatum. High temperatures can easily cause the leaves of Polygonatum to turn yellow and grow slowly, while low temperatures can damage the root system of Polygonatum, affecting yield and quality.

3. Lighting conditions

Polygonatum has high requirements for light and prefers an environment with sufficient light. During the planting process, you should choose a plot with sufficient light for planting and avoid an environment that is too dark.

4. Moisture conditions

Polygonatum sibiricum likes a humid growing environment and has high requirements for water. During the planting process, it is necessary to reasonably arrange the irrigation time and water amount according to the soil moisture and climatic conditions to keep the soil moist. At the same time, attention should be paid to drainage and waterlogging prevention to avoid waterlogging in the soil that may damage the root system.

2. Polygonatum sibiricum Planting Method

1. Site selection and land preparation

Choose a moist, shaded, well-drained plot with deep and fertile soil. The soil should be loose loam or sandy loam with good water retention capacity. Before sowing, the soil should be tilled, harrowed and leveled, and then made into ridges.

2. Breeding method

Polygonatum can be propagated by rhizomes and seeds. Rhizome propagation is to dig up underground rhizomes in late autumn or early spring, select the tender tip part, and cut it into several sections for planting. For seed propagation, the seeds are stored in sand after they mature in August and are ready to be sown in the spring of the following year.

3. Field management

In the early growth stage, inter-cultivation and weeding should be done frequently. If necessary, soil can be added and weeding can be done in the later stage. If there is drought or if it is planted in a sunny and dry place, it needs to be watered in time. If conditions permit, cake fertilizer can be applied, 50 to 80 kg per 667 square meters, divided into two times, and then net fertilizer can be applied every year at 1000 to 1500 kg/667 square meters.

4. Pest and disease control

The main diseases of Polygonatum sibiricum include black spot disease, and the main insect pests include white grubs . Prevention and control methods include clearing the orchard during harvest, eliminating diseased and damaged plants, and spraying Bordeaux mixture or Ticomorb before and in the early stages of the disease.

The above is an introduction to the planting methods and conditions of Polygonatum sibiricum. The harvesting time of Polygonatum sibiricum is generally from September to December in the autumn and winter and before the beginning of spring of the following year. At this time, the above-ground stems and leaves of Polygonatum sibiricum have withered, while the underground rhizomes have matured.
