Description
Technical field
The present invention relates to the medicinal plant engineering field of growing seedlings, specifically a kind of bletilla striata stem tuber epicuticle that makes full use of organizes rapid induction to go out the breeding and seedling method of seedling.
Background technology
The Chinese traditional herbs history of existing thousands of years of China, is still widely used in China and many countries and regions so far.But because traditional Chinese herbal medicine acquisition methods is that to gather and consume a large amount of wild plant resources be cost, in the time gathering and consumption exceedes the regeneration capacity of natural resources, will inevitably cause the in imminent danger of species even to be become extinct.Along with the destruction day by day of natural ecological environment, also further cause the scarcity of resources of medicinal plant simultaneously.
The bletilla striata, have another name called give free of charge, indocalamus orchid, be the one that the orchid family bletilla belongs to, plant Latin Bletilla striata by name.Perennial herb, pseudobulb piece root shape, white, plumpness, has finger-like difference.Stem is sturdy, upright, high 30-60 centimetre.Leaf 3-6 piece, lanceolar or wide lanceolar, tip is point gradually, and base portion sheath shape is embraced stem.Raceme top is raw, sparse, has colored 3-8 piece, spends greatly and beauty aubergine.Petal 3, the lip Long Circle of falling ovum, dark 3 split, and there is wave-formed mouth at middle sliver edge, and side sliver part is coated stamen post.Sepal 3, petal-shaped.Capsule, cylindric, above, 6 vertical ribs are outstanding.Seed is tiny of dust.Late April-late May at florescence, in fructescence 11 months, the last ten-days period.There is mutation to spend the bletilla striata in vain, floral white, garden-variety still has indigo plant, Huang, pink isochrome.Conventional division propagation.Spring young leaves sprout before or autumn and winter overground part withered after, the old strain of turn up, cuts apart pseudobulb and divide and plant, every strain can divide 3-5 strain, every strain must be with terminal bud.Also can adopt seed propagation, but because seed is tiny, hypoplasia, needs to use medium aseptic inoculation, complicated operation, therefore seldom used.
Be mainly used in hemoptysis and spit blood, traumatism and bleeding, sore swollen toxin, chapped skin.Pulmonary tuberculosis hemoptysis, ulcer haemorrhage.Its bulb is containing bletilla colloid, starch, volatilization wet goods.Medicinal, have produce effects, the effect such as tonifying lung hemostasis, detumescence, external application controls that traumatic bleeding, carbuncle are swollen, scald, furunculosis etc.Spend beauty, cultivation is for viewing and admiring.From documents and materials, at present mainly to use bletilla striata propagation by corm, plantation, at good, the fertile sand loam of draining and humus loam, needs warm more dark and damp environment.
Publication number be CN101940158A Introduction To Cn Patent a kind of method of utilizing bletilla striata seeds Fast-propagation seedling, adopt iodophor solution soaking disinfection bletilla striata seeds, in intelligent climate box, induced bundle is sprouted the stage, adopt improved culture medium, and rationally adjust developmental temperature, illumination is implanted and is filled in the stainless steel disc or porcelain dish of matrix through the seedling of cultivating for 35-50 days, then puts into 20-26 ℃ of indoor hardening, within bletilla striata growth of seedling 3-4 month, enters field planting.Shorten the seedling seedling cycle, improved the survival rate of bletilla striata seedling large Tanaka, while having avoided former technology mercuric chloride solution sterilization bletilla striata seeds, human body is worked the mischief.But a lot of bletilla striata seeds ateliosis, bletilla striata seeds does not germinate substantially, and economic benefit can not get effective raising, is difficult to this technology of large-scale promotion.
Publication number be CN102283115A Introduction To Cn Patent a kind of method of Fast-propagation bletilla striata seedling: select bletilla striata mature seed as explant.2) after seed disinfection, be seeded to germination medium, 7 days left and right seed germinations, formed protocorm about 14 days, and cutting protocorm, is forwarded to Protocorm Multiplication medium.3) protocorm is forwarded to inducing clumping bud and proliferated culture medium.4) cutting Multiple Buds makes its amount reproduction, is forwarded to Rooting and hardening-off culture base after waiting Multiple Buds to grow up to the seedling of high about 3cm, in the time that seedling grows up to high approximately 7～10cm, transplants.Solve seedling that current bletilla striata vegetative propagation exists and carried the problems such as virus, deterioration of variety, effective output are low.The present invention can obtain the virus-free seedling of a large amount of sexual propagations under manual control condition, and compared with traditional modes of reproduction, output improves approximately 30%, and the demand and supply contraction of alleviating the bletilla striata is had to positive effect.Adopt this method can make the bletilla striata form planting scale, but its Cultivate administration is more difficult, implantation time also lengthens, and the cost of group training seedling own is high, and peasant economy benefit can not effectively improve, and is also difficult to this technology of large-scale promotion.
Publication number be CN102577814A Introduction To Cn Patent a kind of honeysuckle and the bletilla striata efficiently overlap cultivating method: the bletilla striata is interplanted below the medicinal materials such as honeysuckle, with becoming thoroughly decomposed, animal manure grass covers the bletilla striata, by the management of the operations such as fertilising, weeding, desinsection, results after plantation about 5 years.This production method utilizes same piece of land to produce two kinds of medicinal materials simultaneously, has improved cropping index.Save recruitment cost, production cost reduces, and output increases, and economic benefit significantly improves.But because tree-like honeysuckle has a certain impact to the daylighting of the bletilla striata, directly affect the utilization of the bletilla striata to fertilizer and moisture.Honeysuckle is plucked asynchronous with bletilla striata lepisphere stem expanding stage, also can affect bletilla striata squama expansion of corms, directly affects medicinal herb grower's economic benefit.
