Study On The Utilization And The Biological Characteristic Of Juema (Potentilla Anserina L.) That Is Wild Resource Foliage

Green foliage is the substance base of exist and development of human. Theplant not only connected to people's basic necessity of life, but also related to thestabilization of environments and the health of man and the increase of societyeconomy. Although swift development of high-technology and blindness exploitationof nature resource makes the human society more civilization and richer in 20 century,the wholeness has been cost the unbalances zoology and destroyed circumstance, andmakes covers shadow for human's survival and development. Wild resource foliage isthe important safeguard of people's confinable progress, utilizes efficiently and inreason resource can gets human's civilization sustaining development. Along withmore research about crop in world and the position request of China enter The WTO,the utilization in reason and effectively of resource foliage has been become a studyhotspot. Juema is the root tuber ofPotentilla anserina L., belongs to Rosacrae, Potentilla,and is typical stoloniferous clonal herbage. Potentilla anserina L. distributes abroad inworld. In China ,it distributes many areas, and grows frequently riverside, roadside,hill and pasture, the altitude is about 500～4100 meter. Its root tuber doesn't expandat warm region, often use it as feedstuff. It only expands at high coldness, such asQing-Tibetan Plateau; at there it is called "Juema". Its distributing region is thevastest and a reserve is the biggest and quality is the best in Qinghai province. In folk,Juema is often used as Tibetan medicine and the substance of health protection.Owing to the limit of special geography district and other factors, the research aboutJuema is a little, just about the mensuration and assume of general component andproduction utilization. Qinghai province belongs to typical Qing-Tibetan Plateau climate region. Itsweather is very cold and altitude is high and soil layer is thin and foliage cover rate islow, environment is flimsy. In Qinghai, the environment of primary distributing areaof Juema is tarnal flimsy, such as Yushu and Guoluo, this region is the cradleland ofYangtze River, and Yellow River and The Lantsang .It is called "Cistern of China".All the time, Juema is wild growth. Because the economy of Qinghai province isunderdevelopment, and its quality is the best and individual is the biggest of Juemagrows at these area ,its economy value is higher, so farmers and herders live in therepick Juema as the one of their primary economy origin. The broke out of "SARS"and"poultry flu"large-scale in 2003 and 2004 in the world , makes more and more peopleconscious the significance of boost up themselves immunity. The price of Juema, thegreen food is raised, brought about frantic picking and big acreage meadow destroyed,many area produced high quality Juema become bald land, soil desertize increasinglyseverity. At the same time, eyeless picking also works the Juema quality of marketdeclines. Therefore, researcher studied first and systematically and completely the natureresource survey ,biology and bionomics characteristic, nourishment and activesubstance planting technique, economy value, and so on, the new results as follow:Ⅰ Nature resource survey Juema grows frequently at meadow, hill, wet pasture, riverside, slot, roadside, andthe side shed of livestock; where the air temperature is cold, day difference intemperature is big, radiance is strive ,precipitation isn't rich but concentrated; the soiltypes mainly includes Backland, Castanozems, Alpine meadow soil, Subalpinemeadow soil, Meadow soil etc.; it distributes mostly in Qinghai ,Tibet and some areaof Gansu, but Qinghai's reserves is the biggest and quality is the best; Juema has threevariation in Qinghai, that is Potentilla anserina L． var.anserina, Potentilla anserinaL．var.nuda.Gaud and Potentilla anserina L．Var.serina Hayne. The literature ofJuema is place and ancient codex; in folk, Juema is often used as Tibetan med...
