How to raise seedlings of Panax notoginseng seeds

Panax notoginseng is a perennial erect herb belonging to Panax ginseng of Acanthopanax senticosus, distributed in Yunnan, Guangxi, Jiangxi, Sichuan and other places. It was born at an altitude of 1200-1800 meters above sea level. It has remarkable effects of promoting blood circulation and removing blood stasis, reducing swelling and relieving pain. It has the reputation of "Jinbu" and "Southern Shencao". So how to raise seedlings of Panax notoginseng seeds?

How to raise seedlings of Panax notoginseng seeds

The main results are as follows: 1. The seeds of Panax notoginseng are post-mature and need to be preserved in wet sand from December to January of the following year before they can be released from dormancy.

2. Before sowing, the seeds of Panax notoginseng were soaked in 0.2mol / 0.3 Baomesulphur mixture for 10 minutes, or sterilized with 200mg / kg zinc for 15 minutes, or treated with 58% manganese zinc for 30min, or soaked in 1.5% polyantimycin 200 mg / kg for 30min for 50 minutes, and then soaked for 50 minutes.

3. The germination temperature of Panax notoginseng seeds is 10: 30 ℃, the optimum temperature is 20 ℃, and the dormancy period of Panax notoginseng seeds is 45-60 days. In the process of dormancy, the seedlings need to be treated at low temperature for a period of time before they germinate, and they are very sensitive to light. Traditionally, it is believed that 30% of natural light is needed for normal growth and development, so the shade shed of Panax notoginseng has a saying that "30% of the light is transparent and 70% is shaded." According to the latest research, the most suitable transmittance of Panax notoginseng shed is 812%, and the growth of more than 17% Panax notoginseng will be adversely affected.

4. The seeds of 3-year-old plants with strong growth and free of diseases and insect pests are generally selected from Panax notoginseng, and the seeds are collected and washed off when the fruit is ripe from November to December, and sowed in time, because the germination rate of the seeds is greatly reduced after a week of storage. Before sowing, disinfect the seeds with 0.2-0.3% pomedolite-sulfur mixture for 10 minutes, or with 200-300 times zinc for 15 minutes, and then sow the seeds.
