How to tell the quality of ginseng?

The quality of ginseng can be distinguished from texture, body and dryness.

1, depending on the texture of ginseng.

When selecting ginseng, you need to carefully observe the cross section of ginseng, because the texture of ginseng can be seen from this place. There is no way to break high-quality ginseng. If you say that the ginseng you see is loose in texture, it will break when you pinch it with your fingers, which means that such ginseng has a short growth time and is not very rich in nutritional value. It is not recommended that you buy.

Step 2 look at the reference body

The good ginseng taproot is thick and long. Moreover, the lower end of each ginseng will have some forks, just like a human leg. You can take this into account when choosing.

3. Check the dryness of ginseng.

Now most of the major shopping malls sell dried ginseng. If you buy ginseng through informal channels, be sure to check the dryness carefully. For example, if it is not properly dried, the moisture content is still very high, so it is easy for such ginseng to regain its moisture when it is preserved. When identifying, you should also touch the texture of ginseng to see if it is soft and tender.

Growing environment:

Soil: Ginseng likes sandy loam with loose texture, ventilation, good drainage and fertile nutrients. It is best to have enough phosphorus, potassium fertilizer and humus in the soil, and forest soil, granite weathered soil and mountain yellow sandy soil which are usually rich in humus are better. The pH value of soil is generally 5.5~6.5, and alkaline soil, clayey loess and lime-soaked soil with pH value greater than 7 are not suitable for growth.

Moisture: the soil moisture content is generally maintained at 40%~50%. During the emergence of ginseng in spring, the soil moisture content is about 40%; The temperature is higher in summer, and the water content is about 45%~50%. The moisture content in autumn and the whole year should be 45%~50%.
