Turning over the ground is deep turning, generally in autumn need to turn over the land, at the same time to break the soil, level the land, you can wait for planting.

2. Cultivation methods

First of all, we need to select seeds first, and then put the seeds of licorice into an environment where the temperature is about 20 degrees Celsius. Take it out about seven hours, then rinse it with clean water, dry the water and sow it, 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, but the best planting time is May. Sowing is generally done by drilling or hole sowing, with a row spacing of about 35 cm and a plant spacing of about 20 cm.

3. Field management

Licorrhiza is a perennial herb, usually in the second and third years after planting, in the spring when the need for topdressing, mainly phosphate fertilizer, trenching ring application. The second is that in the year after planting, at least three to four times of watering are generally required. Later, the number of watering can be gradually reduced. When the seedlings grow to about twelve or thirteen centimeters, we should carry out reasonable thinning to ensure the seedling spacing in the field. At least three or four intertilling and weeding sessions per year are also required, and the number of intertilling sessions can be reduced randomly thereafter.

4. Pest control

The resistance of licorice is stronger, and it is rarely affected. But rust, brown spot and powdery mildew are also present in its growth process. These diseases are basically caused by fungal infection, which can be controlled by using Baume sulfur mixture, Bordeaux mixture and Baume sulfur mixture plus rice soup respectively. The most common pests are aphids and red spiders. Aphids and red spiders are common pests in many medicinal plants. We can use fenitrothion or dimethoate emulsifiable concentrate to spray them.

5. Precautions

Licorice planting to pay attention to the place is not much, ten of the details or need to pay more attention, so that you can improve the yield and quality of licorice. First of all, when covering seeds with soil, pay attention to compacting the soil with feet and remember to pour water once. Secondly, in order to improve the emergence rate, many people's treatment methods have certain errors, need to first use 60 to 100 degrees hot water for half a minute heat treatment, and then put into warm water immersion for 24 hours.

The cultivation method of licorice and its precautions are probably like this. If you like the content shared by Xiaobian, remember to pay attention to Xiaobian. At the same time, if you have better planting methods and precautions worth paying attention to, you can also discuss them with Xiaobian.
