1、 Planting time

There are many kinds of precious medicinal materials, and the planting time should be determined according to the plant itself. For example, ginseng, Polygonum multiflorum and medlar are suitable for breeding in spring, generally from March to April. Panax notoginseng needs to breed in winter, which is better from October to November. In addition, Angelica sinensis has low requirements for planting time. It can be planted in spring, autumn and winter

2、 Planting method

1. Sowing method: all kinds of precious medicinal materials can be propagated by sowing method, such as ginseng, Panax notoginseng, Polygonum multiflorum, medlar and angelica. First, choose plump and mature seeds, which can greatly increase the survival rate. The second is the requirement of substrate. Generally, loose, fertile and well drained soil is more suitable for plant growth. Spring sowing should not be too deep. It can be covered with fine soil. If sown in winter, keep warm to avoid freezing to death after germination. After rooting and sprouting for a period of time, it can be maintained normally. Determine the amount of watering or fertilization according to their habits

2. Cutting method: cutting method is only suitable for some plants with strong vitality, such as ginseng, Polygonum multiflorum, medlar, etc. When cutting a strong branch, it usually takes a few leaves. The length depends on the plant. For example, the branches of ginseng are controlled within 8 cm, while Polygonum multiflorum needs 25 cm and medlar needs about 20 cm. Then insert the branches into the soil one-third to one-half, and compact the soil. If it is ginseng and medlar, there is no need to apply fertilizer immediately, and Polygonum multiflorum can apply a little fertilizer appropriately
