Requirements of Environmental conditions for the growth of Panax Notoginseng

Panax notoginseng is a perennial herb of Araliaceae, and the general plant can be as high as about 60cm. The main distribution area is concentrated in the south, Panax notoginseng is mainly used as root medicine, with various effects such as reducing swelling and removing blood stasis, promoting blood circulation and relieving pain. Now, although the planting area of Panax notoginseng is large, it can not be planted everywhere, because Panax notoginseng has certain requirements on the growth environment. Then the editor will give you a brief introduction, let's have a look!

1. Soil

In fact, the requirements of Panax notoginseng on soil is not very strict, in general, in addition to over-acid soil and clayey soil, other types of soil can grow Panax notoginseng normally. However, in order to ensure the normal growth of Panax notoginseng and improve the yield and quality of Panax notoginseng, it is necessary to ensure soft soil and rich humus. It is best to give priority to sandy soil, maintain a certain slope, Panax notoginseng has not been planted in eight years, and its pH is controlled at about 6-6.5.

2. Temperature

Temperature is very important for the growth of Panax notoginseng, and the temperature demand of Panax notoginseng is different in different growth stages. When the seedlings of Panax notoginseng break the soil, the temperature should be controlled at about 22 degrees and the soil temperature should be kept at 12 degrees. If the temperature is below zero, it will cause freezing damage to the seedlings. Then during the growth period of Panax notoginseng, the temperature is kept at 24 degrees, and the soil temperature needs to be controlled at about 18 degrees. If the temperature is higher than 32 degrees for a long time, it will also affect the growth of Panax notoginseng seedlings.

3. Lighting

Light is also a planting condition that can not be ignored when planting Sanqi. When planting Panax notoginseng, it is necessary to ensure a certain degree of shade, do not let the sun direct radiation of Panax notoginseng for a long time, otherwise it is easy to cause Panax notoginseng leaf burn. The annual light requirement of one-year-old Panax notoginseng is about 10% of the natural light, while that of two-year-old Panax notoginseng is about 14%, and that of the last three-year-old Panax notoginseng is about 18%.

4. Moisture

Panax notoginseng has a great demand for water in the process of growth. When planting Panax notoginseng, the moisture in the soil of the seedling bed should be kept at about 28%, and the lowest water content should not be less than 20%, otherwise the plant of Panax notoginseng will be withered and lack of water, which will seriously affect the growth of Panax notoginseng. If it is less than 15%, then the seeds of Panax notoginseng will stop germinating, which will have a great impact on the yield and reduce the planting efficiency.

5. Altitude

In addition to the above four, there is also altitude that we should pay attention to. We should reasonably control the altitude according to the growth years and varieties of Panax notoginseng. If you are planting annual varieties of Panax notoginseng, then the altitude of the planting site should be controlled at about 1300-1500 meters, if it is said to be biennial, then the altitude should be controlled at about 1400-1900 meters to ensure the normal growth of Panax notoginseng.

The above is a brief introduction to the environmental requirements for the growth of Panax notoginseng. The growing environment of Panax notoginseng makes it impossible to grow in many places, so we must pay more attention before planting. That's all for today's introduction.
