Description
Technical field
The invention belongs to Chinese medicine sapling multiplication technical field, and in particular to a kind of bletilla seed sowing two-stages seeding
Method.
Background technology
Bletilla [Bletilla striata (Thunb.) Reichb.f.], it is orchid family bletilla category herbaceos perennial,
It is one of important Chinese medicine, medicinal part is its dry tuber.Its bitter, sweet, puckery, cold nature；Return lung, liver, stomach, tool
There are astringing to arrest bleeding, the function of detumescence and promoting granulation.Except field of medicaments, bletilla is also extensively used for food, tobacco, chemical industry, flowers
Etc. industry.Bletilla distributed areas are wider, but China's bletilla resource is very short, it has also become restrict related pharmaceutical industries, change
The bottleneck of the sustainable developments such as industry.To plant as elder generation, stock breeding is to realize Chinese medicine planting scale, the weight of standardization for agriculture
Link is wanted, is source and the starting point of Chinese Medicine Industry chain.High quality seedling is to improve plant uniformity and product, the premise of quality
And basis.
Although bletilla can produce a large amount of seeds (each Fruit pod 100,000 or so), small (the average mass of 1000 kernel 2.0 of seed
×10-3G) and there is no endosperm, can not normally sprout under field conditions (factors).Bletilla sapling multiplication mode mainly has division propagation, group
3 kinds of fast numerous and seed seedling-raising of training etc..Division propagation breeding coefficient is low, easy infection rots, sowing quantity (300kg/ mus), formation greatly
The time length of scale, and long-term its kind of property of division propagation is easily degenerated.At present, tissue culture technique is the master of bletilla sapling multiplication
Approach is wanted, but this method is higher to facilities and equipment condition and aseptic technique level requirement, and seed after seedling, is gone back in bottle
Needing to transplant by the domestication hardening stage of at least more than 100 days under the conditions of greenhouse, complex operation, cost is higher, when
Between it is longer, there is certain limitation to scale application, and tissue culture needs artificial addition exogenous hormone to promote seed
Sprout and take root, cause its internal hormone chaotic, add variation probability, influence bletilla physiology and metabolic activity, so as to have influence on
The interior quality composition of bletilla.
Found by retrieving, the existing multidigit scholar's research in the country crosses bletilla seed sowing reproduction technique.Patent application, specially

It is middle that seed is seeded in germination fluid (with the addition of methyl α-naphthyl acetate) progress preculture, mix and sow with thin wood chip after Seed sprouting, with
Title of the present invention is close, but way is far different.
Compared with tissue-culturing rapid propagation seedling-raising technique, these seed sowing technologies may have the advantages such as production cost that reduce, but
There is a key issue, that is, large and small seedling phenomenon protrudes, and when taking the seedlings to go out garden in batches, tends to injure small
Seedling.It is known that tiny (the average mass of 1000 kernel 2.0 × 10 of bletilla seed-3G), easy moisture absorption is agglomerating is not easy to scatter, and such one
Come, easily cause became uneven during sowing, very low (seed of mature and plump typically only accounts for whole kind pod to seed vitality in addition
20% or so), cause field emergence extremely irregular (front and rear continue up to 20- 30 days).Because large and small seedling mixes, transplanting is big
Growth course is inconsistent behind field, so as to have influence on bletilla yield and quality.Secondly, even also added in some above-mentioned methods
Plant exogenous hormone, influence whether bletilla follow-up physiological and biochemical activity or even quality component.
To solve the above problems, the present invention provides a kind of bletilla seed sowing two-stages seeding method, bletilla seed is educated
Seedling, which is divided into two different phases such as clove is formed, clove classification is broadcasted sowing, to be carried out, and seed is in grow in natural environment and formed
Clove, then classifying seed and field classification transplanting are carried out to clove, effectively overcome in prior seed direct sowing and seedling
The phenomenon that large and small seedling mixes, improve the field uniformity after seedling regularity and transplanting.The present invention can quickly, on a large scale
Bletilla seed seedling is produced, production cost is well below tissue culture, and after planting transplantation of seedlings crop field, seedling-slowing stage is short, plant uniformity
Height, is advantageous to bletilla High yield, and Technique Popularizing application prospect is good.
The content of the invention
It is an object of the invention to overcome cost height in existing bletilla tissue culture, easily cycle length, variation, and tradition
Large and small seedling mixes, it is necessary to the deficiencies of repeatedly going out garden and field growing regularity difference etc. in seed sowing one-part form nursery, there is provided
It is a kind of to effectively improve plant uniformity, highly efficient and productive, small investment, cycle short seed sowing method for culturing seedlings.
By bletilla seed seedling-raising, from being seeded into out, garden transplanting is divided into clove formation to the present invention, clove classification broadcasts sowing two
The individual different stage is carried out, and can also be undertaken by producer's complete independently by different producer's segmentations, seeling industry ring
Independent, development Chinese medicine seedling specialist is saved, with middle product (clove or seedling) sale, advantageously reduces reduction life
Produce link, reduce investment risk, accelerate Chinese medicine improved seeds and promote, promote seed seedling standardization metaplasia production.Therefore, originally
The Chinese medicine plantation that invention is long to the production cycle, plantation difficulty is high, investment is big has important reference and promotional value.
