Background technology
Rheum officinale is being collectively referred to as a variety of polygonaceae Rheum herbaceos perennials, alias " general ", by it and ginseng, monkshood,
Cultivated land is referred to as " Four Devarajas " together, pushes away as " Zhang Fei in medicine ".Rheum officinale is the Chinese medicine that China finds and used earliest, is four big
One of the most frequently used Chinese medicine, is most praiseworthy medicinal material in Chinese medicine.The successive dynasties traditional Chinese medical science all takes much count of and praised highly to rheum officinale, have
" ginseng murders without mistake, and it is idle that rheum officinale rescues people " is said, Tibetan medicine and pharmacology also has ancient record with largely using.National 8000 plurality of Chinese
Preparation Chinese medicine has to plant 800 more uses rheum officinale to be raw material, originates in " the select water rheum officinale " in Gansu and " the Xining rheum officinale " in Qinghai is praised already
It is full domestic and international.
Modern study shows that rheum officinale has anti-inflammatory and choleretic, soothing the liver purging intense heat, fat-reducing grease removal, hemostasis, decompression, dissipate-swelling, defaecation etc.
Advantage effect." intestines green tea " fat-reducing upsurge swept the country in the recent period, the storm of detoxifying health-care, nowadays the application field of rheum officinale is very
Extensively, consumption constantly increases, and quality raw materials are persistently walked freely, is also the important outlet medicinal material of China, annual requirement is on 10,000 tons of left sides
It is right.
Wild Rhubarb resource is increasingly exhausted, should protect and should not excavate.Artificial growth has been had it long ago, but due to by economy
The induction of interests, the just digging in 1 year of the growth 3 years, the just diggings in 2 years of the growth 5 years, Planting Years not enough have a strong impact on big
The content of yellow active ingredient, causes in the market not meet substantially《Chinese Pharmacopoeia》The rheum officinale of standard.Country will《Chinese Pharmacopoeia》
The legal index of active ingredient of rheum officinale is lowered to 1.5 by original 2.3 in version in 2010, still " 1 year fast-growing " rheum officinale effectively into
Point content does not still reach national standard.
Rheum tanguticum Maxim also known as rheum tanguticum Tschircs, be《Chinese Pharmacopoeia》The genuine rhubarb recorded.Its cold-hartliness is strong, wild issue
On Gansu, Qinghai and other places, be grown in more 2700-4500 meters mountain region border, shrubbery, careless hillside fields band, winter be resistant to minus 20 DEG C with
Under low temperature.Because Rheum tanguticum Maxim is mostly wild, therefore based on should being planted in cultivation technique with wild change man.
Qinghai-Tibet scarcely populated, cold and damp, the arable crops of more than height above sea level 2700m only have highland barley and material
Grass, plantation highland barley is unable to make ends meet, the young substantially all manual labour of going out of labour, and large area hillside is left the land uncultivated.
The content of the invention
