1. How to identify Panax notoginseng?
Panax notoginseng is also known as sunflower, sunflower potato, rattan panax notoginseng, Sichuan ginseng and so on. It is a perennial vine plant of the genus Abelmoschus, which is cultivated in Yunnan, Sichuan, Hubei, Taiwan and other provinces of China, and feeds on buds and leaves.
Panax notoginseng is a fleshy vine with round stems and green stems. It becomes brown after growing up, and adventitious roots are easy to occur in internodes. The leaves are alternate, fleshy, heart-shaped, smooth and glabrous, with short stalks, and the shape is very similar to that of Auricularia auricula. The difference between Panax notoginseng and sunflower is that the axils of Panax notoginseng can grow tumor-like green buds, about 3-4 cm in diameter. During summer, spikes are produced from the upper axils of leaves. The inflorescences are as long as 20 cm. The flowers are small, drooping, Corolla five-petaled, white-green, and the florescence is as long as 3-6 months, but it is not sturdy, so it is difficult to obtain seeds.
2. How does Panax notoginseng reproduce?
Panax notoginseng usually uses asexual propagation methods, including bead propagation and cutting methods, and mainly by cutting propagation.
The main results are as follows: (1) the bulbs are propagated in the leaf axils of the growing plants, and the bulbs at the base of the stem are picked up. If the bulbs are used, they need to be peeled off into a single bulb and planted directly in this nursery, or the seedlings are raised in a nursery pot for about 3 weeks.
(2) cutting propagation from the short internodes in the upper and middle parts of the plant, cutting double-node branches with leaves as cuttings. The seedling bed should use loose loam or sandy loam with 10 cm square cuttage. After cutting, the cuttings should be kept warm and moisturized. The greenhouse should be controlled at about 20 ℃, new roots will grow in about 5-7 days, and seedlings will grow in 20 days. If you plant a small amount in the family, you can put the cuttings in a water bottle at room temperature. Change the water every 1-2 days and plant it in a flowerpot after it grows roots within a week.
