Abstract
A kind of germination method of dendrobium candidum, belongs to Chinese medicine plant field.Step 1: acquisition seed low temperature drying enters and saves at 0-4 degrees Celsius of refrigerating chamber cool place drying；Step 2: potassium permanganate cleans seed disinfection；Then it is rinsed with clear water；Step 3: use temperature: 30 DEG C of warm water impregnates 5 hours, and placing under filter paper or gauze natural lighting after pulling out as shady place temperature is 22-28 degrees Celsius；Step 4: seed spit it is white after, move into germination medium, the germination medium is sterilized wood sawdust, with crushing moss and soil in wood sawdust；Step 5: after step 4 seedling is sprouted, step 4 culture medium entirely being moved into seedling culture medium；Watering keeps wet, is kept in dark place under natural light according to 2-4 hours other times；Step 6: 3 cm thick of seedling plant height is transferred to greenhouse and normally cultivates.Dual culture medium adapts to parasitic character, meets the nutritional need of different phase dendrobium nobile, especially addition moss crushed material, will form one layer of moisturizing layer and protecting film during the cultivation process.
Description
Technical field
The present invention relates to a kind of seed Germination Technique, especially a kind of germination method of dendrobium candidum.
Background technique
Dendrobium candidum (scientific name:Dendrobium officinaleKimura et Migo): stem is upright, cylindrical, long
9-35 centimetres, 2-4 millimeters thick, branch, does not have more piece；Ye Erlie, papery, long round shape lanceolar, edge and middle rib are often with pale purple
Color.Raceme is often issued from the old stem top for having fallen leaf, has 2-3 flower；Petal piece dry film matter, shallow white, oval, long 5-7
Millimeter, sepal and petal yellow green, nearly similar, long round shape lanceolar, lip white, base portion have the callosity of 1 green or yellow
Body, ovum shape lanceolar is more slightly shorter than sepal, middle part reflexed.Stamen column yellow green is about 3 millimeters, and apex two sides respectively have 1 purple point；Medicine
Cap white, long ovate triangle are about 2.3 millimeters, and the nearly sharp point in top and 2 are split.The month at florescence 3-6.Height above sea level is born in up to 1600 meters
The dark and damp rock in mountainous region half on.It is distributed mainly on the ground such as Chinese Anhui, Zhejiang, Fujian.Its stem is used as medicine, and belongs to the benefit in tonic
Negative medicine: reinforcing stomach reg fluid, nourishing Yin and clearing heat.At present according to state's laws relevant regulations, does not allow to acquire field dendrobium nobile and cultivate, mesh
Preceding most of cultivate is that collecting part field plant pollen carries out pollination cultivation, based on artificial breeding is attended to anything else with plant.Current kind
Sub- germination rate is low, irregular, the cultivation of medicinal dendrobium still with plant it is mitogenetic based on.
Summary of the invention
In view of the above problems, the germination method emergence rate that the present invention provides a kind of dendrobium candidum can reach 80%, survival rate can
Reach 70%, whole year can be implemented, and can sow at any time, and nursery the reaction of seed greenhouse cultivation it is good.
A kind of summary of the invention: 1 germination method of dendrobium candidum, comprising the following steps:
Step 1: acquisition seed 20-25 low temperature drying enters 0-4 degrees Celsius of refrigerating chamber 20 minutes；It is saved at cool place is dry；
Step 2: potassium permanganate cleans seed disinfection；Then it is rinsed with clear water；
Step 3: use temperature: 30 DEG C of warm water impregnates 5 hours, places under filter paper or gauze natural lighting after pulling out as darkness
Place；Temperature is 22-28 degrees Celsius；
Step 4: seed spit it is white after, move into germination medium, the germination medium is sterilized wood sawdust, in wood sawdust
With crushing moss and soil；
Step 5: after step 4 seedling is sprouted, step 4 culture medium entirely being moved into seedling culture medium；Watering keeps wet, under natural light
It is kept in dark place according to 2-4 hours other times；
Step 6: 3 cm thick of seedling plant height is transferred to greenhouse and normally cultivates.
Preferably, in 5 steps, the seedling culture medium is following components according to poidometer are as follows: wood sawdust
50-60 parts；10-20 parts of bark；10-20 parts of forest leaf mould；2-6 parts of moss crushed material or more ingredient is uniformly mixed.
Preferably, the seedling culture medium is following components according to poidometer are as follows: 55 parts of wood sawdust；15 parts of bark；
15 parts of forest leaf mould；4 parts of moss crushed material or more ingredients are uniformly mixed.
Preferably, Additional nutrient solution in step 6.
Preferably, potassium permanganate described in step 2 be 1.5% potassium permanganate, 20-30 degrees Celsius of water temperature.
The utility model has the advantages that
The germination method emergence rate that the present invention provides a kind of dendrobium candidum can reach 80%, and survival rate can reach 70%, whole year
Implement, and the seed greenhouse cultivation reaction of nursery institute is good, goes water to facilitate preservation using drying, because it is Celsius to plant the relatively thin 0-4 of skin
Degree can achieve the purpose for promoting seed dormancy to save for a long time for low temperature 20 minutes.Dual culture medium adapts to parasitic character, meets
The nutritional need of different phase dendrobium nobile, especially addition moss crushed material, will form one layer of moisturizing layer and protection during the cultivation process
Film prevents pest and disease damage from invading and harassing dendrobium nobile growth, has protective effect to the dendrobium nobile in sprouting and growth.Facilitate large-scale plantation, saves
Less manpower and time cost.
