Medicinal plant licorice cultivation technology

Licorice, also known as sweet root, red licorice, or grass, is a leguminous plant used for its root and rhizome in traditional medicine. It has detoxifying properties, helps soothe the lungs and relieve coughs, strengthens the spleen's Qi, and harmonizes the effects of other herbs. Licorice thrives in temperate regions, typically growing in plains, mountainous areas, or river valleys at elevations between 0 and 200 meters. The ideal soil type is sandy with a neutral to slightly alkaline pH. It prefers environments with ample sunlight and significant temperature differences between day and night. In China, the northwest, north, and northeast regions are particularly suitable for cultivating this valuable herb.

● Field Management

1. When planting, maintain a spacing of about 30 cm between seedlings, and keep the distance between plants at 18.5–20 cm to ensure proper growth.

2. Irrigation is crucial during the early stages of growth. Keep the soil consistently moist after emergence to support seedling development. Watering should be adjusted based on soil type and salinity: sandy soils without alkali or with slight salinity can be watered after sowing, while clayey or highly saline soils should be watered before sowing. Once the plants are established, watering is usually no longer needed.

3. Weeding is essential in the first year, especially during the seedling stage. After the second year, when the roots begin to develop, weeds become less competitive, and manual weeding is no longer necessary.

4. Apply sufficient base fertilizer before sowing. In the spring, phosphorus fertilizers can be added, and organic manure can be applied before each mu (a traditional Chinese unit of area) in winter. Since licorice has nitrogen-fixing root nodules, it generally does not require additional nitrogen fertilization.

5. Disease and pest control is important. During rainy seasons, licorice is prone to powdery mildew and rust, while spider mites may appear in dry conditions. These can be managed using 40% Dimethoate EC diluted at 1000–1500 times.

● Harvesting and Processing

Licorice roots grow deep underground, so careful digging is essential to avoid damaging them. Do not cut or damage the roots during excavation. After digging, remove the stems and soil, but do not wash the roots with water. Separate the main and lateral roots, and remove any fibrous parts, hairs, and branches. Dry the roots thoroughly, bundle them into small groups, and continue drying until fully dehydrated. Alternatively, licorice can be harvested in early spring before the leaves and stems emerge, but the quality of roots harvested in the fall is typically superior. Proper handling ensures that the final product retains its medicinal value and potency.
