A kind of dendrobe cultivation method improving facility utilization rate
Technical field
The invention belongs to dendrobe cultivation technical field, be specifically related to a kind of dendrobe cultivation method improving facility utilization rate.
Background technology
Herba Dendrobii (Dendrobium) has another name called Herba Dendrobii, for the perennial grass of growing nonparasitically upon another plant of the orchid family (Orchidaceace) Dendrobium (Dendrobium)
This plant, is important medicinal and ornamental plant, belongs to the thing of " Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) " appendix II
Kind, original producton location is distributed mainly on Tropical Asian and subtropical zone, and Australia and Pacific Islands, the whole world there are about more than 1500
Kind, China there are about 76 kinds, and major part is distributed in the ground such as southwest, south China, Taiwan, wherein has nearly 40 kinds to have medicinal valency
Value.The kind of China's Herba Dendrobii only accounts for global about 5%, but its medicinal development and utilization is taken its place in the front ranks of the world, and Herba Dendrobii is
China's tradition rare Chinese medicine, applicating history is long, has nourishing YIN and clearing away heat, the stomach reinforcing that promotes the production of body fluid, nourishing the lung to arrest cough, defying age, carries
High immunity, blood circulation promoting and blood stasis dispelling, raising cardio and vascular function, effect of life lengthening, the most famous has Herba Dendrobii (D.
Officinale), Herba Dendrobii (D.huosanness), Dendrobium nobile (D.nobile), Dendrobium fimbriatum Hook. (D.fimbiratum), drumstick
Herba Dendrobiis (D.chrysotourn) etc., they are all used as medicine with fresh or dry stem.Some medicinal dendrobium kind exports for a long time, enjoys great prestige
Some areas of Southeast Asia and America and Europe.Herba Dendrobii has " soft gold ", the title of " human world Herba mesonae chinensis " in China, in being referred to as in history
First of China's " nine big Herba mesonae chinensis ", to laryngopharyngeal diseases, gastroenteropathy, cataract, cardiovascular disease, diabetes and suppression tumor
Growth has significant curative effect, particularly has good inhibitory action to lung carcinoma cell, after eliminating cancer radiation, chemotherapy
Side effect and recovery physical ability, effect is fairly obvious.So people are growing to the demand of Dendrobium Plants, market demand
Constantly expand.
Wild Dendrodium primary growth is at the torrid zone, subtropical zone virgin forest and similar warm and moist environment, and happiness cool place is moistening, logical
The miniclimate that wind is foggy, avoid high temperature, be dried, high light, be grown on more height above sea level 900~1500 meters, average temperature of the whole year 12 DEG C~
18 DEG C, relative humidity 60%~75%, transmittance about 60%, season of growth temperature 20 DEG C~28 DEG C, winter temperature 9 DEG C~
In the evergreen broadleaf forest of 12 DEG C, frostless foggy, annual rainfall 500~1000 millimeters, often grow nonparasitically upon another plant in half dark and damp thick forest trunk
Or on rock, and often and the unicellular lower eukaryote association such as lichen, Folium Pyrrosiae and lichens, primary growth is at lofty mountains and steep hills overhanging cliff and rock
In crack of stone gap, growth conditions require warm, moisten, ventilate, breathe freely, leak.
Although Herba Dendrobii can result and fruit and seed amount big, 1 mellow fruit pod is contained within the seed of up to ten thousand, but the most solid
Rate is the lowest, the Natural seed setting rate of such as Herba Dendrobii only 0.31%.The seed of Herba Dendrobii is the most tiny, and fetal development is incomplete,
Lacking endosperm tissue, need could sprout with some fungus (blue bacterium) symbiosis under natural conditions, germination rate is extremely low, such as iron sheet stone
The seed germination rate of dry measure used in former times is less than 5%.Traditional artificial propagation mode such as plant division, cuttage etc., reproduction speed is slow, and the rate of increase is very
Low, the requirement of merchandized handling can not be met far away.
Due to the Herba Dendrobii particular/special requirement to growing environment and the limitation of distribution, under natural environmental condition, self-reproduction rate is very
Low, and the growth promoter of Herba Dendrobii is slow, so wild Dendrodium rare numbers, wild resource is very limited.China is for a long time
Dependence excavates wild resource to meet the market demand, owing to excessively excavating and developing, causes Dendrobium Plants heavy damage,
Cause natural resources the most rare, traditional famous and precious Herba Dendrobii wild resource being used as medicine such as Herba Dendrobii, Herba Dendrobii, Dendrobium nobile
Being on the verge of exhaustion in China, natural production can not meet far away the market demand, and this most seriously constrains a large amount of relevant medicine
Supply, and ecological and bio-safety are caused harm greatly." the Chinese Plants Red Data Book " that in August, 1998 promulgates
The Dendrobium Sw of more than 70 kinds is listed in protection plant, is more protected by " People's Republic of China's conservation of wild plant regulations "
Protect.Strengthen the protection to Dendrobium Plants, it is achieved the sustainable use of Dendrobium Plants is extremely urgent, the Fast-propagation of research Herba Dendrobii
Method and artificial cultivation technique are protection Herba Dendrobii species and the important channel meeting the market demand.
From 20 century 70s, begin to tissue rapid propagation technology and the research of artificial cultivation technique of Herba Dendrobii both at home and abroad.
Herba Dendrobii is stricter to the requirement of environmental condition, it is desirable to warm, moisten, have half cloudy half light environment of sufficient scattered light, and it is raw
Long thermophilic is 15 DEG C~30 DEG C, and optimum growth temperature about 20 DEG C stops growing below 5 DEG C, and seedling 10 DEG C with
Easily endure cold down.Relative air humidity requires to keep 70%~more than 80%, avoids and is dried and hydrops, particularly starts sprouting
Sprout and when being formed with new root, need sufficient moisture.Light as requested shading summer and autumn 70%, shading in winter 30%~50%.
Therefore, using the facility cultivations such as booth is that Herba Dendrobii large-scale production preferably selects.Meanwhile, Herba Dendrobii is Epiphyte, certainly
Under the conditions of Ran, primary growth is on the dark and damp trunk of some high megaphanerophytes or limestone, thus under conditions of artificial propagation seedling
Simulating natural environment condition can also carry out Emulational culture.Emulational culture refers to select near-nature forest in the wild original producton location of Herba Dendrobii
Sylvan life, in simulating natural environment condition, the ecosystem environment of Herba Dendrobii growth carries out tame method, plants according to Ecology
The difference of attached master during training, can be divided into tree cultivation, stone to plant and fertile soil 3 kinds of forms of cultivation.
The root of Herba Dendrobii is aerial root, has the most aerobic and shallow root.Herba Dendrobii during long-term growing evolution, plant
Specialization is not have a Gen Mao and can only form the plant of trophism symbiosis with certain fungus, relies on mycelia to absorb moisture and inorganic
Material, and decompose the bark of root attachment by bacterial strain or organic base material such as lichen obtains the organic nutrient such as glucose, protein,
G and D is carried out in the special dietary mode of mesotrophy half heterotrophism.So, the cultivation matrix of Herba Dendrobii should be good with permeability
Raw material is main, it is desirable to loose ventilative, draining is good, and fertilizer is appropriate, and water conservation, fertilizer-preserving ability are strong, begins in whole trophophase
Eventually in state of partly becoming thoroughly decomposed, optimal upgrowth situation so could be obtained.The breathability of dendrobe cultivation substrate and water-retaining property are to obtain
The key of high transplanting survival rate, and the nutrition of substrate is sprouting sprouting and the restriction factor grown after transplant survival, too low or mistake
High all it be unfavorable for the sprouting surviving rear sprouting and growth (Lin Jiangbo, Dai Yimin, Zou Hui, etc. Fujian Herba Dendrobii artificial breeding
Technical research. Fujian Journal of Agricultural Sciench, 2010,25 (5): 606~609.).Substrate for dendrobe cultivation mainly has: peat, saw
Wood flour, wood shavings, bagasse, mushroom bran, Pericarppium arachidis hypogaeae, coconut shred, lichen, rubble, bark etc., conventional substrate is mostly selection
Therein several form for primary raw material mixture, and than dendrobe cultivation substrate conveniently typically based on peat and/or lichen
Wanting raw material, and peat is non-renewable resources, reserves are limited, and a large amount of exploitations can cause the destruction of ecological environment.Herba Dendrobii at present
Artificial culture in Yunnan, Guangdong, Zhejiang, Jiangsu, the ground such as Hunan win initial success, Main Cultivation form is for set at booth etc.
The built on stilts cultivation bed executing built-in the highest 50~80 centimetres carries out substrate bed cultivation, under bed ground and Spatial General 6 R leave unused useless.
Along with development and the application of tissue culture technique, the tissue culture technology of current Herba Dendrobii is mature on the whole.Utilize tissue culture's skill
Art breeds seedling becomes the tame main source of seedling of current Herba Dendrobii, by carrying out after tissue culture's amount reproduction tissue cultured seedling
Artificial facilities cultivation is the Main Means meeting the market demand, and group training test tube Seedling successfully carries out field-transplanting and growth, is to realize
The key that Herba Dendrobii industrialization produces.But owing to Herba Dendrobii requires harshness to growing environment, there are many factors still to restrict the product of Herba Dendrobii
Industry metaplasia is produced, and wherein, owing to tissue culture environment and artificial culture environment also exist bigger difference, tissue cultured seedling needs by nothing
Collarium border adapts to extraneous natural environment comprehensively, is transitioned into autotrophy by heterotrophism, and because the resistance of tissue cultured seedling is weak, survival ability is poor,
The low bottleneck always perplexing Herba Dendrobii large-scale production of tissue cultured seedling transplanting survival rate, governs the Planting of dendrobe tissue culture Seedling
Training scale.Particularly to carry out survival rate during Emulational culture lower for Herba Dendrobii, such as directly cultivate after Herba Dendrobii tissue cultured seedling bottle outlet
Survival rate to Emulational culture base is about about 30%, and the transplanting survival rate of tissue cultured seedling the most always restricts Herba Dendrobii
The principal element of large-scale development (Xu Guangtao. improve the research of Herba Dendrobii Emulational culture survival rate method. Anhui forestry section
Skill, 2011,37 (6): 62-64.).Tissue cultured seedling transplanting survival rate is low not only a biggest relation with cultivation matrix, and with cultivation
Illumination in environment, temperature, humidity have the biggest relation.Such as, at artificially controlling temperature, iron sheet stone in wet beam-connected greenhouse is controlled
Dry measure used in former times cultivation survival rate can reach more than 95%, if cultivated in the booth more modernized, can heel in without middle
Seedling exercising link, tissue cultured seedling is direct field planting after taking out from bottle, also can obtain higher survival rate and higher yield.But it is out of office
During outer Emulational culture or in simple plastic greenhouse during cultivation, the direct transplanting survival rate of candidum tissue culturing seedling is the lowest, the lowest
In 50%, and poor growth (Zheng Kuanyu, Deng Junlang, Zhao Hui. Herba Dendrobii test tube Seedling cultivation technique is studied. Crop Diseases in Yunnan section
Skill, 2010 (3): 21-22.;Song Shun, Xu Yi, Li Jingyang. the tissue culture and rapid proliferation progress of Herba Dendrobii. China
Agronomy is circulated a notice of, and 2013,29 (33): 286-290.).The research of money galaxy of literary talent etc. is thought, utilizes the cultivation that water retention property is good and breathability is strong
Training substrate can make the transplanting survival rate of Herba Dendrobii tissue cultured seedling improve, and the planting effect of layering substrate is more preferably, transplanting suitable
Substrate is layering substrate: bottom 3/10 bark+top 7/10 wood flour, its transplanting survival rate and rudiment number are higher, and (money galaxy of literary talent opens
Build rosy clouds, Wu Kunlin, etc. Herba Dendrobii sapling multiplication and cultivation research. tropical and subtropical plant journal, 2013,21 (3):
240-246.), but the operation that this research uses layering substrate culture is more complicated, and transplant the survival rate only 78% of latter 70 days statistics.
So, Herba Dendrobii is preferably formed with a transition stage heeling in seedling exercising in the middle of test tube Seedling bottle outlet to field production, makes tissue cultured seedling suitable
After having answered natural environment, field planting could obtain preferable cultivation effect again, otherwise can have a strong impact on transplanting survival rate, the speed of growth
With Herba Dendrobii yield.
In order to improve the adaptability of dendrobe tissue culture Seedling environment to external world, solve this restriction industrialization low of tissue cultured seedling transplanting survival rate
The bottleneck problem of development, Kong Dedong etc. filters out the matrix formulations of peat+perlite+Vermiculitum (volume ratio 31 1), application
Hole plate seedling growth technology, makes the survival rate of candidum tissue culturing seedling more than 95%, and seedling growth is healthy and strong, has promotional value
(Kong Dedong, Huang Chongping, Zhou Jianhua, etc. the optimal screening of Herba Dendrobii plug seedling substrate. agricultural science and technology communication, 2010 (8):
70-72.).Xiao Ying etc. select eriophorum peat soil perlite 311 to heel in for substrate, make candidum tissue culturing seedling
Heel in survival rate 95% (after transplanting 60 days), and the growth of stem very notable (Xiao Ying, Zhang Yaozhou. substrate seedling exercising season is to ferrum
The impact that skin Herba Dendrobii test tube Seedling is heeled in. Xinyang agricultural higher junior college journal, 2013,23 (2): 93-94.).Xu Guangtao improves suddenly
The key technology of mountain dendrobe cultivation survival rate is to heel in seedling exercising substrate before Emulational culture after dendrobe tissue culture Seedling bottle outlet
Carry out the seedling exercising of a period of time.Seedling exercising substrate is pressed with broken bark bits, meter Xin Shi and the aobvious acid northeast peat soil etc. in original producton location
Certain proportion is prepared, and the substrate of this material can not only meet the needs of seedling exercising, but also the beneficially Herba Dendrobii Seedling seedling exercising phase terminates
After be transplanted on the stone matter base of Emulational culture.Through the seedling exercising phase of 45~60 days, make the cultivation survival rate of Herba Dendrobii
From original about 30% bringing up to more than 90% (Xu Guangtao. improve the research of Herba Dendrobii Emulational culture survival rate method.
Anhui forestry science and technology, 2011,37 (6): 62-64.).The Cortex Pini of 5~10 millimeters of pulverizing such as Liu Shihui, 2~4 millimeters of Margaritas
Rock, according to the cultivation matrix of 41 ratio mixing, carries out heeling in seedling exercising with 50 hole dishes, the candidum tissue culturing after domestication
Seedling stem stalk is sturdy, leaf color is dark green, root system is slightly white, and adapts to ability and resistance enhancing, and transplanting survival rate is up to more than 97%
(Liu Shihui, Plumbum preparatium maple, Yao Yongkang, etc. candidum tissue culturing seedling greenhouse acclimatization technology is studied. Agriculture of Anhui science, and 2013,
41(17):7477-7478,7495.).The main contributions of these 4 researchs is, the hole plate seedling growth being generally used for vegetable nursery
Technology or heeling in technology are applied in the cultivation of Herba Dendrobii, make the transplanting survival rate of dendrobe tissue culture Seedling be significantly improved.It lacks
Be trapped in, first 3 all using peat as the primary raw material of substrate, and the mud and charcoal of China is fewer, and is can not be again
Raw natural resources, although the research of Liu Shihui etc. with peat as the primary raw material of substrate, but because of the nutrition of this substrate
Seldom, after heeling in higher to fertilizing management requirement, it is desirable to " thin fertile duty execute ", not only need repeatedly to spray Liquid Fertilizer, and
Particle slow release to be applied is fertile, and Herba Dendrobii could be helped to grow up strong and sturdy;Meanwhile, these 4 researchs are required for special setting
Executing and carry out heeling in seedling exercising, owing to the adaptability of tissue cultured seedling is poor, the requirement to environmental condition is higher, so the requirement to facility
The highest with the level of cultivation management, if the facility heeling in seedling exercising is simpler and cruder or extensive management, heeling in of tissue cultured seedling survives
Rate still ratio is relatively low.But, the mode of China's current Herba Dendrobii facility cultivation is typically all and uses built on stilts cultivation bed to cultivate,
Ground and Spatial General 6 R under cultivation bed are all idle useless, and this is to cultivating facility one to waste greatly.Herba Dendrobii facility substrate
During cultivation, the Herba Dendrobii Seedling producing cultivation typically requires that intensity of illumination is 8000~15000 luxs, and heels in the stone of seedling exercising phase
Dry measure used in former times seedling (tissue cultured seedling) intensity of illumination be 3000~during 10000 lux ratio conveniently, first 2 months after particularly heeling in
Intensity of illumination can not be too high, and suitable intensity of illumination is generally 3000~7000 luxs.We utilize overhead height be 60~
80 centimetres, width is 1.2~1.5 meters, leaves when carrying out dendrobe cultivation in the facility in wide 0.5~1 meter of passageway between bed and bed
It has been observed that be 8000~during 15000 lux when meeting intensity of illumination on built on stilts cultivation bed, under the bed of built on stilts cultivation bed
The intensity of illumination in face is in the range of 3000~10000 luxs, and under relative air humidity bed, space is than built on stilts cultivation bed
Superjacent air space typically wants high 3%~5%, and under temperature changing amplitude (maximum temperature and the difference of the minimum temperature) bed of every day, space ratio is built on stilts
Cultivation bed superjacent air space is typically low 1 DEG C~3 DEG C.Owing to carrying out the Herba Dendrobii seedling during seedling exercising vacation than seedlings to cultivation ring
Border requires tightened up, it is desirable to intensity of illumination is relatively low, and shade Du Genggao, and relative air humidity is bigger, the change phase of epidemic disaster
To less, and Herba Dendrobii built on stilts cultivation bed space below and ground just can meet these conditions, are by dendrobe tissue culture Seedling
Heel in the place that seedling exercising is more satisfactory.

After Herba Dendrobii Plug seedling field planting cultivation bed, 2 weeks interior fine days to regulate degree of shading and reach more than 70%, tan by the sun with anti glare anti static coatings and cause seedling
Wilt, affect survival rate.After field planting, 2 weeks planted agents use the mode of spraying to keep air humidity, are sure not to water, after field planting
1 week seedling not yet Fa Xingen, air humidity is preferably maintained at 75%~85%, and after field planting, the 2nd week plant starts Fa Xingen, empty
Air humidity degree is positively retained at 70%~75%.After field planting the 1st week and the 2nd week respectively with 0.2%~0.3% potassium dihydrogen phosphate and
The flower of 1500~2000 times of liquid the more No. 1 (a kind of from the plant of imported from America general equilibrium fertilizer, basic recipe: nitrogen, phosphorus,
Potassium content is 20-20-20, adds M 77 trace and REE elements of world patent) each foliage-spray 1 time.After field planting 2 weeks
Management method can carry out cultivation management routinely, after general field planting 2 years can start commodity Herba Dendrobii of gathering.Due to just heeled in
Dendrobe tissue culture Seedling is the most tender and lovely, regularly to spray initial several days every days clear water 1~2 times, air humidity guarantor in 1 week after heeling in
Hold 80%~90%, do not water.After heeling in 1 week, plant starts Fa Xingen, can reduce spray timings, air humidity keep 70%~
80%.Substrate keeps alternation of wetting and drying beneficially root of hair to sprout, and the water management of substrate should be grasped and parch drenched principle, heels in
If the dry available watering can of substrate waters and executes substrate to drenching (water content about 65%) after 2 weeks.After heeling in 20 days, every 1~2
Spray 1 foliage fertilizer week, the potassium dihydrogen phosphate with 0.2%~0.3% and the flower of 1500~2000 times of liquid the more No. 1 alternately spray
Execute.Slowing down even stop along with the reduction of temperature, Herba Dendrobii growth of seedling after entering autumn and winter, the requirement to moisture is the most gradually dropped
Low, so water spray and the number of times of fertilising should be gradually decreased, in the feelings of the inconspicuous hydropenia of substrate (when water content of substrate is less than 30%)
Not watering under condition, the most every 15~20 days of winter selected fine day 9:00~10:00 in the morning to water 1 time, suitable after water spray
Work as ventilation.Typically heel in seedling exercising 5~garden field planting can be gone out in 12 months.
