Origin of medicinal materials: sand ginseng is mainly produced in Anhui Province, Jiangsu Province, Zhejiang Province; Radix Ginseng is mainly produced in Guizhou Province, Henan Province, Heilongjiang Province, Inner Mongolia Autonomous region, Jiangsu Province. The output of Guizhou Province is large, and the quality of Anhui, Jiangsu and Zhejiang provinces is good. Sold all over the country.

Cultivation: like warm or cool climate, cold, although resistant to drought, but in the long-term state growth, also need the right amount of water, seedling stage, drought often causes death of seedlings. Generally speaking, the sand ginseng sown in that year does not blossom and bear fruit, but should blossom in June of the following year, flowering from June to September, and the seeds will mature in September. It is suitable to be cultivated in sandy loam with deep and fertile soil layer, rich in humus and good drainage. Seed propagation is divided into spring sowing and winter sowing, spring sowing in the north in April and winter sowing before freezing in November. Apply sufficient base fertilizer for land preparation, compost or barnyard manure 45000ml 60000kg per lhm2. After soil preparation, make the bed 1 meter wide, open a shallow trench according to the row spacing of 40 cm, spread the seeds evenly into the ditch, cover the soil by 1.5 cm, suppress slightly, water it, and often keep the soil moist. Spring sowing seeds will emerge after about 2 weeks. The seeds sowed in winter appeared in spring in the second year. After the seedlings are unearthed, we should pay attention to weeding and loosening the soil. the seedlings are about 3 centimeters high, and the seedlings are fixed when the seedlings are 10 mures 15 centimeters high. one strong seedling is left every 10 Murray 15 centimeters. In order to prevent lodging, it can be combined with fertilization to cultivate soil and choke roots during the growth period. In order to keep the seedlings strong, topdressing should be applied frequently at seedling stage. In addition to topdressing once every year after plant withering and before emergence, topdressing should be done once in May, July and September, mainly human and animal manure. When the plant height is 45 cm, topping in time can control the plant height, reduce nutrient consumption and be beneficial to root growth. The disease has root rot, which can be sprayed with 50% wettable powder 500 times. Brown spot can be sprayed with 65% Dyson zinc wettable powder 500 times. Insect pests include aphids, ground tigers and so on.
