Licorice is a commonly used medicine, which is often used in our lives, such as licorice in cough syrup. Its medicinal part is mainly its rhizome, mainly used in the treatment of heat-clearing and detoxification, expectorant and cough and so on. The main producing areas of licorice in China are * *, Inner Mongolia, Ningxia and Gansu. So do you know how licorice is raised? What do you need to pay attention to when planting? Let's take a look at it.

1. Soil selection

Licorice likes light, generally grows in arid or semi-arid sandy soil or desert areas, and has strong adaptability. Resistant to drought, heat, cold and salt. Although the underground of the planting site is not generally 1.5 meters, it is planted in the soil with loose soil, good drainage, deep soil layer, perfect soil structure and alkaline acidity. Turn over the land is deep, generally need to turn the land over in the autumn, at the same time to break the clods, leveling the land, you can wait for planting.

2. Cultivation methods

First of all, we need to select the seeds, and then put the licorice seeds in an environment with a temperature of about 20 degrees. Take it out in about seven hours, then rinse with clean water, dry the water and sow, so that the germination rate of seeds can reach more than 90%. Licorice planting time is also relatively wide, generally spring, summer and autumn can be planted in three seasons, but the best planting time is May. Generally, the way of sowing is strip sowing or hole sowing, and the spacing between rows and plants is about 35 cm and 20 cm respectively.

3. Field management

Licorice is a perennial herb, generally in the second and third year after planting, topdressing is needed in spring, mainly phosphate fertilizer, ditching ring application. Secondly, in the year after planting, it is generally necessary to irrigate at least three or four times, until later, you can slowly reduce the number of watering. When the seedlings grow to about 12 or 13 centimeters, we should carry out the seedlings reasonably to ensure the distance between the seedlings in the field. At the same time, at least three to four times of intertillage and weeding are needed each year, and the number of intertillage can be randomly reduced in the future.

4. Pest control

Licorice resistance is strong, generally rarely disease. However, rust, brown spot and powdery mildew also exist in its growth process. These diseases are basically caused by fungal infection, which can be controlled by Baumedushi sulfur mixture, Bordeaux liquid and Baumedu stone sulfur mixture plus rice soup respectively. And the most common pests are aphids and red spiders, aphids and red spiders are more common pests in the cultivation of many medicinal materials, we can use fenitrothion or dimethoate EC to spray.

5. Points for attention

There are not many places to pay attention to in licorice planting, and some details still need to be paid more attention to, which can improve the yield and quality of licorice. First of all, when covering the soil and covering the seed, you should pay attention to compacting the soil with your feet and remember to water it once. Secondly, in order to improve the emergence rate, many people have some misunderstandings in their treatment methods. They need to do heat treatment with hot water of 60 to 100 degrees for half a minute, and then soak them in warm water for 24 hours.
