Description
Technical field
The present invention relates to Chinese herbal medicine planting technology field, particularly the tame key technology of rare traditional Chinese medicine bark of ash is nursed young plants in hothouses and is cultivating method mulched.
Background technology
Bark of ash is a conventional Chinese medicine, and property is flat, and flavor is hot, bitter.Function with wind-damp dispelling, clearing away damp-heat, stopping numbness pain.Be used for the tired pain of arthralgia due to wind-dampness, the contraction of muscle arteries and veins, joint, infantile malnutrition heating jaundice, have blood in stool, difficult urination, aphtha poison, vaporization heat of bone, illnesss such as hectic fever polydipsia and married woman's tire heat.It (is gentianin, Gentianine), gentianidine (is gentianidine, Gentianidine) and gentianal that the bark of ash chemical composition of Chinese materia medica mainly contains erythricine; Also contain volatile oil and carbohydrate.
The medicinal history in existing more than 2000 year of bark of ash is a decoction medicine materical crude slice commonly used, is again the primary raw material of Chinese patent drugs such as scythian lamb rhizome ball, Duhuo jisheng ball, the SHUJIN WAN that dispels the wind, anti-arthritis pill, lumbar vertebrae arthralgia pain treating bolus.Present about 30 kilograms of China's annual turnover.This product late 1980s, its price all was stabilized in about 20 yuan/kilogram to the beginning of the nineties.Rise in price after nineteen ninety-five, price is 50 yuan/kilogram at present.
Bark of ash relies on the wild resource supply the market at present fully.The wild resource regional height above sea level that distributes, weather cold, ecotope is very fragile, and main area is in China height above sea level 2200--3500m scope.Bark of ash is a herbaceos perennial, grows in alpine meadow, border, shrubbery and cheuch.The 7-9 month at bark of ash florescence, the fruit phase 8-10 month, seed maturity continues up to mid-November in mid-September.
Because the tight valency of goods is raised, the crushing collection causes the wild resource exhaustion, causes that market supply is nervous more, and this vicious circle grows in intensity, and makes bark of ash endangered.China classifies bark of ash, gentiana crassicaulis Duthie, radix gentiane dahuvicae as national three-level protective wild medicinal plant.About 1 millimeter of bark of ash seed diameter, percentage of seedgermination is extremely low, and the natural propagation rate of bark of ash is very low under the carded sliver spare out of office, and poor growth is difficult to the restorative source.Bark of ash distribution area mostly is grassland region greatly, excavates in the process, and each strain bark of ash takes the square turf of 25cm, and the soil that digs out covers the grass quilt of about radius 25cm, forms the very important wind erosion and the point source of water erosion.Excavate in a large number make the grassland destroyed riddled with gaping wounds, become one of reason of medicinal material producing region grass-land deterioration.Therefore the research and development of artificial cultivation technique promptly are the main paties of protection bark of ash wild resource; Also be to eliminate careless destroyed hidden danger, the needs of protection ecology of grassland; More provide the needs of clinical application.But the technology of still not having at present a kind of desirable artificial cultivation bark of ash.
