Description
Technical field
The present invention relates to a kind of organic selenium-rich dendrobium candidum and breeding method thereof, belong to the culture technique field.
Background technology
Selenium is a kind of humans and animals trace elements necessary, have remove free radical anti-oxidant, delay senility, biological propertyes such as anticancer, enhancing immunity, antagonism heavy metal.Selenium totally is divided into inorganic selenium and organic selenium two big classes: the former comprises selenate, selenite etc., and inorganic selenium assimilation effect for humans and animals is poor, and risk of toxicity is big, and improper use very easily causes selenosis; The latter mainly is meant the selenium with the biological organic molecule combining form, and the organic selenium absorption ratio is high concerning humans and animals, and risk of toxicity is little, is more suitable for mending the requirement of selenium.
Dendrobium candidum is as " first of the Chinese nine immortal grass ", have enhancing immunity, promote digestion, antitumor, prolong function such as aging.If let the rich selenium of dendrobium candidum, can strengthen then that it is antitumor, prolong functions such as aging, enhancing immunity, undoubtedly human health there is huge benefit, have bright development prospect.
Chinese invention patent " a kind of cultural method of selenium-enriched officinal dendrobium stem " (application number: 200510061530.8) disclose a kind of method that sodium selenite obtains selenium-enriched officinal dendrobium stem at last that directly in tissue cultivating and seedling matrix, adds.But because the stem of noble dendrobium needs a large amount of pourings in the actual production process, the eluviation of selenium is remarkable, because the absorption efficiency of selenium is not high enough, and the stability of the stem of noble dendrobium Se content of different batches maturation cannot not be known.
Summary of the invention
The objective of the invention is: a kind of organic selenium-rich dendrobium candidum and breeding method thereof are provided, and the absorption efficiency that solves selenium in the production of prior art selenium-enriched officinal dendrobium stem is not high, the problem that can not produce the dendrobium candidum of different batches.
Technical scheme of the present invention is: a kind of organic selenium-rich dendrobium candidum is characterized in that: the Se content of said organic selenium-rich dendrobium candidum is the 6.3-20 mg/kg, wherein organic selenium content >=80%.
Preferably, the Se content of organic selenium-rich dendrobium candidum is the 8-15 mg/kg, wherein organic selenium content >=80%.Preferably, the Se content of organic selenium-rich dendrobium candidum is the 9-12 mg/kg, wherein organic selenium content >=80%.
The present invention also provides and cultivates the breeding method that this kind has the stem of noble dendrobium vegetable material of medical usage; After dendrobium candidum seedling bottle outlet is transplanted the selenium-rich nutritive agent is sprinkling upon on the plantation matrix; All the other can obtain the stable selenium-enriched officinal dendrobium stem of different production batch Se contents according to normal cultured after three months.Selenium-rich nutritive agent composition comprises: selenium source (5 ~ 20): microorganism fertilizer (5 ~ 20): humic acid (1 ~ 2).
Wherein said selenium source can be selenate, selenite, contain selenium ore machining object, nanometer selenium plant nutrient agent (Suzhou selenium paddy Science and Technology Ltd.; Model is XGP001A) wherein one or more than mixing, make that the ultimate density of selenium remains on 500 ~ 15000 mg/kg in the selenium source with any.
Preferably, selenium source, microorganism fertilizer, humic acid weight ratio are 20:20:1 in the said selenium-rich nutritive agent, and the Se content of said selenium-rich nutritive agent is 1500 mg/kg.
Preferably, in matrix, apply the selenium-rich nutritive agent in the said method after, Se content is 2 ~ 7 mg/kg in the said matrix.
Preferably, in matrix, apply the selenium-rich nutritive agent in the said method after, Se content is 2.7 ~ 5 mg/kg in the said matrix.
Preferably, in matrix, apply the selenium-rich nutritive agent in the said method after, Se content is 3 ~ 4 mg/kg in the said matrix.
Preferably, the selemium nutrition agent is for promptly joining i.e. usefulness in the said method, and compound method is with the full and uniform according to the above ratio mixing of selenium source, microorganism fertilizer and humic acid, obtains said selenium-rich nutritive agent.
Preferably, selenium source is the nanometer selenium nutritional agents in the said method.
Preferably, in the said method in the selenium-rich nutritive agent humic acid that uses be fulvic acid, said microorganism fertilizer form is a powdery, wherein active bacterium amount ≧ 8 1,000 ten thousand/grams.
Produce the concrete steps of organic selenium-rich dendrobium candidum with the agent of this selenium-rich nutritive:
Say that the above-mentioned selenium-rich nutritive agent of certain mass is sprinkled in the dendrobium officinale substrate, be mixed into the matrix that Se content is 2 ~ 7 mg/kg, make selenium fertilizer absorb all the other through the leaching of watering again according to the dendrobium candidum normal cultured.
Microorganism fertilizer used herein is a multiple beneficial microorganism composite fermentation, and product form is a powdery, can make the abundant activation of selenium in the nanometer selenium nutritional agents, thereby makes dendrobium candidum selenium absorption efficiency higher.
Humic acid used in the present invention, can adsorb in the soil with selenium fertilizer in the short time unemployed selenium fertile, and absorbed by the dendrobium candidum root in the later stage, reach assimilation effect and slow releasing function better.
Advantage of the present invention: the absorption efficiency of selenium of the present invention significantly improves.It is stable that the present invention can produce the Se content of dendrobium candidum of dendrobium candidum different batches of different batches.
