Description
Technical field
The invention belongs to technical field of medicinal plant cultivation, and in particular to a kind of bark of eucommia method for culturing seedlings.
Background technology
The bark of eucommia (Eucommia ulmoides Oliv) is the distinctive rare economic tree of China, in Subtropic of China to warm
There are cultivation, about 5,000,000 mu of cultivated area in 26 provinces (area, city) in temperate zone.Bark of Eucommia Ulmoides be China's special product rare traditional Chinese medicine and
Important foreign exchange earning goods and materials, make light of one's life by commiting suicide the resistance to effect of waiting for a long time with strengthening the bones and muscles, filling liver kidney, long term usage, are Chinese medicine top grade.Modern age largely grinds
Study carefully proof, Eucommia Fruit has high economic value and a Utilization prospects, pericarp (kind skin) containing chlorogenic acid, Aucubin,
A variety of mineral elements such as the plain disaccharide glucoside of Geniposidic acid, rosin, polysaccharide, amino acid and Zn, Mn, Cu, Fe, Ca, P, B, Mg, K,
With the pharmacological function similar with Bark of Eucommia Ulmoides, and have no toxic side effect；It is particularly worth mentioning that, bark of eucommia benevolence contains abundant
The unrighted acids such as alpha-linolenic acid, wherein alpha-linolenic acid content are up to more than 60%, with notable reducing blood lipid, hypotensive and suppression
Thrombotic diseases, the prevention effect such as miocardial infarction and cerebral infarction.The bark of eucommia is in addition to traditional medicine, or produces a variety of functional food
Quality raw materials.
The raising technology of the bark of eucommia is relatively more, and common method includes following six kinds：Sowing and breeding, cutting propagation, root turion breed,
Graft seedling growth, press strip breed the tissue cultures with the bark of eucommia.The bark of eucommia routine graft seedling growth process be：Mid or late March is sowed, in August
Ten days to late September grafting, the 2nd year spring cut anvil, bud picking, management, Second Year winter seedling.It can be seen that due to bark of eucommia rootstock seedling early stage
Growth is slower, using traditional breeding methods, and " grafting protocol of the bark of eucommia " one text that such as Li Wenxing is delivered, eucommia bark seed sowing is worked as
Year, August part can be only achieved grafting standard later, and one plant of grafting breeds time needs 2 years, and breeding seedling-wood breeding is slow-paced
Problem has seriously constrained the sound development of bark of eucommia industry.Patent of invention CN102550304B discloses a kind of bark of eucommia grafting with improved seed seedling
Fast breeding method, this method be use with wooden plate budding form, be conducive to bark of eucommia seedling to breed, but still have improvement raising transfer
Connect necessity of rate.
The content of the invention
It is an object of the invention to provide a kind of method of utilization grafting quickly breeding bark of eucommia seedling, this method is grown directly from seeds with American elm tree
Seedling is stock, and bark of eucommia scion is grafted in wherein, shortens the breeding cycle of bark of eucommia grafting, accelerates bark of eucommia seedling breeding speed
Degree.
To achieve these goals, the present invention is achieved using following technical scheme：
A kind of bark of eucommia method for culturing seedlings, comprises the following steps：
(1) stock seed treatment
Select the seed of 6-10 age of tree American elm trees to be pre-processed, sand and vermiculite are first pressed 3:2 volume ratio is mixed into
Sandstone batch mixing, then the potassium nitrate of mass concentration 0.5%, 0.02% ammonium molybdate are pressed 5:1 volume ratio is mixed into mixed solution, then
Mixed solution is uniformly sprayed in sandstone batch mixing, sandstone batch mixing is moistened, its moisture content remains 42-48%, sandstone is obtained and mixes
Expect wet feed, 1 is pressed with American elm seed:5 volume ratio is mixed thoroughly, and 12-24h is handled under conditions of 4-10 DEG C, sifts out American elm seeds
Son；
(2) stock is nursed young plants in hothouses
Set using nursing young plants in hothouses, in greenhouse be easy to control the spraying of environment, auxiliary heat, divulge information, shelter from heat or light, light filling facility, its
In, Light To Dark Ratio remains 16h:8h, is additionally provided with pond and cultivates ground, cultivates ground bottom and surrounding laying wood-plastic board, substratum
Bedding thickness 15-20cm culture medium, matrix is by vermiculite, the cattle and sheep excrement that becomes thoroughly decomposed, Pleurotus nebrodensis mushroom bran, bark of eucommia dry branches and fallen leaves powder by quality
Than 3：2：2：1 is mixed and made into the special seedling medium of American elm, during sowing, by pretreated American elm seed bunch planting in the cultivation in greenhouse
In matrix, management in time；
(3) scion is selected
Growth selection is healthy and strong, the bark of eucommia elite stand of no disease and pests harm, and the non-lignifying of clip or semi-lignified current-year branch connect
Fringe, is cut into 5-6cm segments, every section of band 2-3 bud；
(4) grafting
When 1 year during the thick 1cm of raw American elm seedling ground diameter, select the American elm of the sound flourishing, no disease and pests harm of robust growth, root system real
Raw seedling is stock, away from the 2-3cm of ground that stock is crosscutting, next knife is split from otch center, deep 2-3cm takes a scion by under
Face is whittled into two-sided wedge shape, inserts stock plastic tape colligation, mouth is sealed with wax or yellow mud, is watered, topdressed in time, anti-disease pest
Evil, cut anvil management；
(5) transplant
The bark of eucommia grafting of grafting survival is transplanted into crop field or the field planting of plantation garden, is watered, topdressed in time, diseases prevention
Pest management.
The advantageous effects of the present invention：Present invention selection is close with bark of eucommia affiliation, and growth is rapid, adaptability
By force, the raw seedling in 1 year of the American elm tree of well developed root system is stock, cultivates bark of eucommia seedling using scion grafting grafting, has dramatically speeded up Du
Zhong Miao reproduction speeds, while also shortening the breeding cycle of bark of eucommia grafting.
