The stem vine cutting method is mainly adopted in production. Here mainly introduces the method of stem vine cutting:

1. Seedbed preparation

The nursery bed is prepared in the greenhouse. The length of the seedbed is 5-6m and the width is 1.2m-1.5m. The formula of nutritious soil is 2x3 edible fungus and 1lap3 garden soil. Stir evenly, add appropriate amount of dried chicken manure, sprinkle on the seedbed, rake fine leveling, the thickness of nutritive soil is generally the most suitable 10cm.

2. Cuttage

First of all, cut the stem branches of Panax notoginseng, which are more than one year old, with about 15cm length and 2-3 nodes, to ensure the germination rate, insert 4-5cm deep into the soil along the growth direction of the leaves, maintain proper spacing, facilitate root growth, water thoroughly at one time, and do not need to water the second time. It is best to insert bamboo pieces into the arch shed on both sides of the seedling bed, to make the bamboo pieces firm, and to buckle the shed with plastic sheeting.

Suitable for planting in the land with better watering conditions, the most suitable temperature for the growth of stems and leaves of Panax notoginseng is 25-30 degrees during the day and about 15 degrees at night, and the suitable ground temperature for root system and underground tubers is 20-22 degrees, and Panax notoginseng needs more fertilizer. The combined application of nitrogen, phosphorus and potassium fertilizer has the advantages of strong growth, high yield and good quality. if too much nitrogen fertilizer is applied, it will cause poor quality and easy to be infected with diseases and insect pests.
