Detailed Explanation of Licorice Planting Methods and Precautions

Licorice is a commonly used medicinal herb that is often used in our daily lives; for example, cough syrup contains licorice as an ingredient. Its medicinal part is mainly its rhizome, which is mainly used for clearing heat and detoxifying, and for eliminating phlegm and relieving cough. The main producing areas of licorice in China are **, Inner Mongolia Yiji, Ningxia and Gansu, and other places. So do you know how licorice is cultivated? And what precautions should be taken when planting it? Let's take a look below.

1. Soil selection

Licorice likes light and generally grows in arid or semi-arid sandy soil or desert areas, and has strong adaptability. It is drought-tolerant, heat-tolerant, cold-tolerant, and also salt-alkali tolerant. The planting site's underground water level or although not yet generally should be below one point five meters, and it should be planted in soil that is loose, well-drained, deep, with a complete soil structure, and slightly alkaline in pH. Plowing is deep plowing; generally in autumn the land needs to be turned over, and at the same time the clods of soil should be broken up and the land leveled, then you can wait to plant.

2. Cultivation method

First we need to select seeds, then place the licorice seeds in an environment at a temperature of about twenty degrees for sweat treatment. Take them out after about seven hours, then rinse them clean with clear water, dry off the moisture, and sow them; in this way the seed germination rate can reach more than ninety percent. The planting time for licorice is also relatively broad; generally it can be planted in spring, summer and autumn, but the best planting time is May. Sowing is generally done by drilling or hole sowing, with a row spacing of about thirty-five cm and a plant spacing of about twenty cm.

3. Field management

Licorice is a perennial herbaceous plant. Generally, in the second and third years after planting, topdressing is needed in spring, mainly with phosphorus fertilizer, applied in a circular trench. Second, in the year after planting, generally at least three to four irrigations are needed, and later the number of waterings can be gradually reduced. When the seedlings grow to about twelve or thirteen cm, we should reasonably thin the seedlings to ensure the spacing between seedlings in the field. At the same time, at least three to four cultivations and weedings are needed each year, and later the number of cultivations can be reduced as appropriate.

4. Pest and disease control

Licorice has strong resistance and generally rarely develops diseases. However, rust, brown spot and powdery mildew also exist during its growth process. These diseases are basically caused by fungal infection, and can be controlled with Baume degree lime-sulfur mixture, Bordeaux mixture, and Baume degree lime-sulfur mixture plus rice washing water, respectively. The most common pests are aphids and red spiders. Aphids and red spiders are relatively common pests in the cultivation of many medicinal herbs, and we can use fenitrothion or dimethoate emulsifiable concentrate for spraying and killing.

5. Precautions

There are not many points to pay attention to when planting licorice, but some details still need more attention, as this can improve the yield and quality of licorice. First, when covering with soil to bury the seeds, be careful to press the soil firm with your foot, and remember to water once. Second, in order to improve the seedling emergence rate, many people's handling methods have certain misunderstandings; you need to first use hot water at sixty to one hundred degrees for a half-minute heat treatment, then place them in warm water and soak for twenty-four hours.

The cultivation methods and precautions for licorice are roughly like this. If you like the content shared by the editor, remember to follow the editor. At the same time, if you have better planting methods and points worth noting and guarding against, you can also discuss them with the editor.
