Ginseng planted artificially in garden ginseng is generally called "garden ginseng". Origin: Ginseng planted artificially, mostly planted in Jilin area of China, so it is also called "Jilin Ginseng". According to research, about 250 years ago in the Qing Dynasty, wild ginseng with shoots began to be transplanted in Northeast China, and gradually developed into seed planting. The artificially planted ginseng was called "garden ginseng". Its excavation time is in September, and the garden ginseng is generally excavated for 5 ~ 7 years, because the excavation is too early, the ginseng pulp is insufficient and the quality is not good. According to different production methods, garden ginseng can be divided into red ginseng and sugar ginseng. Ginseng Radix Rubri: Clean fresh ginseng, cut off tender roots, steam for 2-2.5 hours, and take out or dry in the sun to make ginseng Radix Rubri. Red ginseng is divided into two categories. Among them, reeds are long, long and have long lateral roots. The others are "ordinary red ginseng". Efficacy: Warming. Sugar Ginseng: Soak the cleaned fresh ginseng in boiling water until it is about six-ripe, take it out and prick holes around the ginseng with bamboo needles, put it in a basin, pour syrup into it, soak it in sugar for 24 hours, then wash off the epidermis syrup, and then dry it in the sun or bake it slowly with fire. Efficacy: it is peaceful and can be eaten directly, and its efficacy is not as good as that of red ginseng. Origin of Korean ginseng: It is the same variety as domestic ginseng, so it is named after it is produced in North Korea and South Korea. Most products on the market now are Korean ginseng. When digging, you should generally choose ginseng strips that are more than 6 years old, full of water and long. Korean ginseng can be divided into red ginseng and white ginseng according to different production methods. Ginseng Rubra: Steam it with high-temperature steam for 2 hours until it is fully cooked, dry it, remove the ginseng whiskers, and press it into irregular square columns. Efficacy: Warming. White ginseng: choose short and inferior Korean ginseng, put it in boiling water for a while, and then dry it. Efficacy: mild in nature. Morphological characteristics of perennial herbs; The taproot is fleshy, cylindrical or spindle-shaped, and the fibrous root is slender; The rhizome (reed head) is short, with stem marks (reed bowl) and buds on it; Stem solitary, erect, 40 ~ 60 cm high. Leaves are palmately compound leaves with 2-6 longitudinal leaves, which change with age: L has 3 leaflets, 5 leaflets 12 in 2 years, 23 leaflets in 3 years, 3-6 leaflets in 4 years, 4-5 leaflets in 5 years, with a maximum of 6 leaflets; There are 3 ~ 5 leaflets, with the largest 1 in the middle, ovoid or ovoid, 3 ~ 12 cm long and 1 ~ 4 cm wide, wedge-shaped at the base, tapering at the apex, fine-pointed and serrated at the edge, and sparse bristles along the midvein. Umbellies have terminal florets; The flower is bell-shaped and has five teeth; Petals 5, yellow green; Stamens 5, filaments short, anthers spherical; Below the room, 2 rooms, style 1, stigma 2-lobed. Berry drupe oblate or kidney-shaped, bright red when mature; Seed 2, oblate, yellow and white. The characteristic ginseng has a humid and cold climate, with an average temperature of -23-5℃ in October and 20-26℃ in July, 1. Strong cold tolerance, low temperature of -40℃, suitable growth temperature 15-25℃, forest environment with small temperature difference between day and night, and accumulated temperature of 2000-. The soil is well drained, loose and fertile brown forest soil with deep humus layer or mountain gray brown forest soil with pH value of 5.5-6.2. Most of them live in mixed coniferous and broad-leaved forests or deciduous broad-leaved forests dominated by Korean pine, and the canopy density is 0.7-0.8. The main tree species is Korean pine. et Zucc。 Five-pointed maple Maxim. ，Tiliamandschurica Rupr。 Et motto. , Ulmus pumila (Trautv. ) Mayr, phellodendron amurense.

The flowering period is June-July and the fruiting period is July-June. Protective value Ginseng is a precious tonic, which has great medical and economic value for a long time. In China, it has been used as medicine for about 4000 years. However, due to long-term over-exploitation, the natural distribution area has decreased, and the Central Plains producing areas represented by Shangdang Dangshen, namely southern Shanxi, southern Hebei, Henan and western Shandong, have long been extinct. At present, wild ginseng in Northeast China is extremely scarce, so it is of special significance to protect the natural resources of this species. Protective measures Ginseng has been listed as a national rare and endangered protected plant, and Changbai Mountain and other nature reserves have been protected. Other distribution areas should also be protected, and mining is strictly prohibited, so that ginseng resources can be gradually restored and increased. It has been widely cultivated in three northeastern provinces, and recently introduced in Hebei, Shanxi, Shaanxi, Hubei, Guangxi, Sichuan, Yunnan and other provinces. The key points of ginseng cultivation should pay attention to the special environment, dormant embryo, slow growth and delicate characteristics. 1) ginseng planting should choose a slightly acidic soil with a certain slope and rich humus. 2) Sowing: It is one of the important keys to master the understanding of seed germination characteristics and low temperature stratification before germination. Sprouting seeds can be sown in spring, and cracked seeds can be sown in autumn. 3) Transplanting: it can only be transplanted after 2-3 years of sowing. Pay attention to cold protection when planting in autumn and drought resistance when planting in spring. 4) After planting or transplanting ginseng seedlings, we must pay attention to shading, weeding, disease prevention, and sweet, slightly bitter and flat return to menstruation.
