The latest key points of Panax notoginseng field management

Panax notoginseng is a very good traditional Chinese medicine in our country, which is mainly used in the root, and has various effects such as promoting blood circulation and removing blood stasis, reducing swelling and relieving pain. Although it has a vast wild area, but in order to meet the market demand, the area of artificial planting is also getting larger and larger. When planting Panax notoginseng, field management is very important. So the editor brings you the field management technology of Panax notoginseng planting today. Let's take a look at it.

With the growth of Panax notoginseng, the transmittance is adjusted reasonably. The Panax notoginseng plants of 3-4 years or so cry until the light transmittance, increase the yield, promote the root expansion and enhance the disease resistance of Panax notoginseng plants.

3. Water and fertilizer management

In the sprouting and flowering period of Panax notoginseng, if it is dry, it should be watered in time to ensure that the soil is moist and promote the growth of Panax notoginseng. However, when there is much water in the rainy season, we also need to ensure that we do a good job of drainage and reduce the soil water content in time after the rain to prevent stagnant water from rotting the roots.
