CN106385857A - Propagation method of dendrobium officinale seeds - Google Patents

Abstract

The invention is applicable to the technical field of plant cultivation and provides a propagation method of dendrobium officinale seeds. The method comprises the following steps: A, in the period from Qingming to Grain Rain after the cold passes in spring, a laid seeding bed is sprayed with water by an atomizer to be fully drenched, and seeds are sown on the seeding bed; B, after the seeds are sown, 85%-90% of humidity is maintained for sawdust, and as the dendrobium officinale seeds are quite small, required moisture is sprayed after atomized, so that the seeds are prevented from being washed away; C, after more than a month, most of the seeds germinate, the temperature is strictly controlled to not exceed 35 DEG C, and thin organic fertilizer is sprayed at the same time. The lowest germination rate of the seeds is about 40%, the highest germination rate is about 60%, the average germination rate is about 45%, the transplanting survival rate reaches 98% or higher, and the economic benefit is greatly improved.

Description

A kind of propagation method of Seeds of Dendrobium Candidum

Technical field

The invention belongs to technical field of plant culture, more particularly, to a kind of propagation method of Seeds of Dendrobium Candidum.

Background technology

Herba Dendrobii is listed in " first of Chinese nine big Herba mesonae chinensis ", since the Tang and Song Dynasty, has been listed in royal tribute always.Li Shizhen (1518-1593 A.D.) ?《Compendium of Materia Medica》Middle evaluation Herba Dendrobii " reinforcing YIN-essence benefit essence, thick the intestines and stomach, never sufficient in benefit, flat stomach gas, long muscle, Fructus Alpiniae Oxyphyllae remove frightened, Make light of one's life by commiting suicide macrobiosis "；Among the people it is called " help Herba mesonae chinensis ".Additionally, the stem of Herba Dendrobii can clearing away heat and promoting production of body fluid, anti-inflammatory analgetic, clear and rich larynx Throat, has good curative effect to treatment hoarse voice.

Herba Dendrobii is listed in " first of Chinese nine big Herba mesonae chinensis ", since the Tang and Song Dynasty, has been listed in royal tribute always.Ferrum is current The main consumption market of skin Herba Dendrobii also mainly carries in the Zhejiang of China and Shanghai one, and also there is little pin expense in the big city such as Beijing； In addition it is exactly Hongkong and Macro and south east asia, western developed country also has import from China in the past few decades for a long time, in the last few years, with The propagation of TCM Culture, consumption figure is also expanding.

Because dendrobium officinale requires extremely harshness to natural ecological condition, natural propagation rate is again extremely low, due to a large amount of Unordered excavation, early in eighties of last century the eighties, Herba Dendrobii is just treasured medicinal plant in imminent danger by what country was classified as focused protection Thing.

The Herba Dendrobii huge market demand.Herba Dendrobii is YIN nourishing, prophylaxis of tumours, the first-selection of enhancing human body immunity power.Ferrum Skin Herba Dendrobii is the optimal Chinese crude drug of promoting the production of body fluid to quench thirst, has significant improvement result, market prospect to the yin-deficiency constitution of middle-aged and elderly people Very wide.

In terms of current market, Herba Dendrobii finished product is that supply falls short of demand in market, and superfine pure Herba Dendrobii price is every Kilograms 70,000 yuan about.30,000 yuan of one-level Herba Dendrobii Herba Dendrobii extract price per kilogram, and out of stock in spite of rising price, its yield only has demand 4/10000ths.It is expected that the yield of Herba Dendrobii in 10 years is still difficult to meet the demand in market.According to statistics, whole Herba Dendrobii at present Market year total demand is 8000～10000T, and annual incremental with 20% demand.And current manual's plantation iron sheet Herba Dendrobii is at the early-stage, the increase to Herba Dendrobii quantity required for the domestic tens of listing Pharma Inc.s and health product manufacturer, Also have some profiteering business being driven by interests to go deep into each place of production and search order, thus it is serious not to result in Herba Dendrobii resource Foot.Also not up to 200 tons of the Herba Dendrobii that the whole nation produces, much can not meet the market demand.It can be seen that Herba Dendrobii plantation industry Profit is considerable.

Herba Dendrobii is typically grown between height above sea level 100-3000 rice height, often grows nonparasitically upon another plant in tree above or on rock, happiness temperature Warm, moistening and half shade environment, can not resist cold.18～30 DEG C of thermophilic of growth, trophophase is with 16～21 DEG C of more particularly suitable, rest periods 16～18 DEG C, evening temperature is 10～13 DEG C, and the temperature difference is maintained at 10～15 DEG C most preferably.Day temperature is more than 30 DEG C to stone Less, winter temperature is not less than 10 DEG C to dry measure used in former times growth effect.Seedling is easily endured cold below 10 DEG C, and the environmental condition of growth is required Harsh.The natural propagation ability of dendrobium officinale is low, poor growth.And at present during Herba Dendrobii biological engineering, plant , often less than 20%, survival rate after transplanting is also less than 60% for seed germination percentage.This greatly limits the cultivation of Herba Dendrobii.

Content of the invention

It is an object of the invention to provide a kind of propagation method of Seeds of Dendrobium Candidum is asked it is intended to solve above-mentioned technology Topic.

The present invention is achieved in that a kind of propagation method of Seeds of Dendrobium Candidum, the method comprising the steps of：

A, be selected in after spring severe cold clear and bright to season in grain rains, first to the seed bed atomized water spray completed so as to fully Drenched, then seed is sowed on seed bed；

After B, seed are broadcast, the humidity that makes wooden bran both keep 85-90%, it is additionally, since the seed very little of Herba Dendrobii, required water Part will be sprayed after atomization again, prevents seed to wash out；

C, through a wheat harvesting period, seed is most of germinate after, strict temperature control not can exceed that 35 DEG C, sprays organic thin simultaneously Fertile.

The further technical scheme of the present invention is：Described temperature is 20-28 DEG C.

The invention has the beneficial effects as follows：Seed germination rate minimum about 40%, highest about 60%, average out to 45% about, And transplanting survival rate up to more than 98%, is greatly improved economic benefit.

Specific embodiment

The propagation method of the Seeds of Dendrobium Candidum that the present invention provides, details are as follows for it：

A, be selected in after spring severe cold clear and bright to season in grain rains, first to the seed bed atomized water spray completed so as to fully Drenched, then seed is sowed on seed bed.

After B, seed are broadcast, the humidity that makes wooden bran both keep 85-90%, it is additionally, since the seed very little of Herba Dendrobii, institute Need moisture content will spray again after atomization, prevent seed to wash out.

C, through a wheat harvesting period, seed is most of germinate after, strict temperature control not can exceed that 35 DEG C, sprays organic matter simultaneously Thin fertilizer.Described temperature is 20-28 DEG C.

The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.

Claims (2)

1. a kind of propagation method of Seeds of Dendrobium Candidum is it is characterised in that the method comprising the steps of：
