Background technology
Rhizoma Gastrodiae is herbaceos perennial, is distributed in China's most area.Its dry tuber commonly uses and famousr and precious Chinese medicine simply, is clinically used for the disease such as headache dizzy, extremity numbness, child convulsion, epilepsy, tic, tetanus.The acquisition of rhizoma Gastrodiae relies on wild resource in the past always, and the 20 wild change men of century 70 plant successfully, and rhizoma Gastrodiae is planted by family becomes staple source.Rhizoma Gastrodiae is chosen as by World Conservation Union species of easily endangering; and be put in the appendix II of " CITES "; also be put in China's " national key protected wild plants register (second batch) " simultaneously; being II grade of protective plant, is one of primary raw material for the treatment of cardiovascular and cerebrovascular diseases medicament.
Rhizoma Gastrodiae is born in the more and moistening sylvan life of humus, and shrubbery and careless slope also have on the sunny side.Rhizoma Gastrodiae is generally cultivated in China, distributed more widely, and rhizoma Gastrodiae main product is planted in Southern Shaanxi, Northern Sichuan Province, West of Hubei Province and other places by family.Rhizoma Gastrodiae adopts stem tuber to breed usually, but owing to affecting by miscellaneous bacteria, there will be by for degradation phenomena, yields poorly and unstable, affect rhizoma Gastrodiae production greatly.The another kind of method of producing rhizoma Gastrodiae adopts seed sexual propagation exactly, but under natural conditions, seeds of Gastrodia elata sexual propagation germination rate is low, is only 1%.Gastrodia elata sexual propagation seed germination must rely on Germination Strain supply nutrition, can improve seeds of Gastrodia elata germination rate under the effect of Germination Strain, and is conducive to forming rhizoma Gastrodiae ball stem, and is grown to serve as common Gastrodia Elata Stem Tuber.Domestic explored gastrodia elata seed Germination bacterium has Mycen osmundicola, dendrobium mixture, Mycena orchidicola and Mycena anoectochila), and wherein dendrobium mixture is applied more in rhizoma Gastrodiae artificial planting.
At present in the cultivating process of gastrodia elata sexual propagation Germination Strain, the blank that normal employing saw dust, white sugar, wheat bran, starch etc. mix is as medium, this powder-mixed medium is usually because miscellaneous bacteria is attacked and moisture is wayward too much, affect the growth of Germination Strain, and culture base-material complicated component, technical process is loaded down with trivial details, and cost of manufacture is higher.
Patent name: the medium of tall gastrodia tuber germination strains, the applying date: 2010.11.04, publication number: CN102153377A, publication date: 2011.08.17, disclose a kind of culture medium prescription of tall gastrodia tuber germination strains, this medium adopts Qingmu Tree fruit to be primary raw material, mix with wheat bran, sawdust, sugar, starch, this base-material increases substantially although can make gastrodia seed germination rate have, but there is the acquisition of Qingmu Tree fruit to be subject to seasonal restrictions, can not pluck at any time, not easily obtain, the shortcoming of base material formulation complexity.
Summary of the invention
The object of the present invention is to provide the breeding method of a kind of gastrodia elata sexual propagation Germination Strain three grades of kinds, solve the problem of miscellaneous bacteria serious interference and formula complexity in existing gastrodia elata sexual propagation Germination Strain cultivating process.
Another object of the present invention is the medium providing a kind of gastrodia elata sexual propagation Germination Strain three grades of kinds, solves existing medium base material formulation complicated, the problem that cost is high.
