II. Planting techniques of Polygonatum polygonatum

1. Soil

To plant Polygonatum polygonatum, first of all, we need to select the soil with fertile soil layer and good drainage performance. Here, we recommend the sandy loam soil containing humus, which is well drained and deep. After filling the soil, it is divided into units and ridges according to the usual method of planting other plants, and the width and length are arranged in advance.

2. Watering

Before planting, Rhizoma Polygonatum chooses to use plant ash to treat the wound to dry for a day, which is to disinfect the wound and then plant it into the soil. Watering normally in the first two days, it is recommended that everyone should be watered three times a week in the later stage, not too often.

3. Field management

Rhizoma Polygonatum often needs to remove weeds in the early stages of growth, and you can choose to do it once a year in April, June, September and November. After weeding and topdressing, the fertilizers are mainly cake fertilizer, calcium phosphate, miscellaneous fertilizer, etc., mixed and stirred in accordance with the usual way of fertilization, and then cover the soil. Huang Jing likes water sources and cloudy days, so we should also pay attention to weather changes when carrying out field management.

4. Harvest

Polygonatum polygonatum is generally harvested in autumn and spring, and the harvest quality in autumn is higher than that in spring. Dig up the rhizome, wash the soil, then steam it in a steamer, and then take it out when it is observed that there is an oily luster. After taking it out, put it in the ventilated and suitable sunlight to dry. If it is the rainy season, you can use drying instead of sunlight.
