Abstract
The present invention provides a kind of breeding gardens to create technology, row is planted between " sunlight girl " American elm and Chinese pumila, make " sunlight girl " American elm and Chinese pumila parent each other, obtained hybrid seed, it is strong and forge a good relationship with Chinese pumila natural crossing, the defects of the advantages of yellowish green ratio of progeny seed seedling leaf color is stablized overcomes Chinese pumila low output, and growing way is weak and the yellowish green differentiation of seed seedling is unstable that the blue chrysomelid ability of the anti-elm of " sunlight girl " American elm is utilized.
Description
Technical field
The present invention relates to landscape art fields, and in particular to a kind of breeding garden creates technology.
Background technology
In general, the artificial forest that breeding garden is clone by artificial selection or filial generation is formed, by isolation or
Operation Measures, to avoid or reduce the intrusion of external source pollen, management objectives are production hereditary quality improved varieties, with full
The needs of sufficient reforestation.
The seed harvested from the Chinese gold leaf elm of adult is by after planting, will appear yellowish green of leaf color in offspring nursery stock
The phenomenon that miscellaneous, therefrom selection retain the golden yellow pure nursery stock of leaf color, can be used as Chinese pumila nursery stock culture.But Chinese gold leaf
Yield is relatively low under field conditions (factors), and growing way is weaker for the self-produced seed of elm, and the yellowish green ratio differentiation of leaf color of seed seedling is unstable.And
" sunlight girl " American elm is tree-like soft and graceful, and ornamental value is good, and the blue chrysomelid ability of anti-elm is stronger, and with Chinese pumila natural hybrization
It is good, and the yellowish green ratio of leaf color of progeny seed seedling is stablized.But it does not find also that Chinese pumila and " sun can be made in the prior art
Light girl " American elm hybridizes good technology.
Therefore the breeding garden establishment technology of Chinese pumila and " sunlight girl " American elm parent each other can be made by how providing one kind,
It is those skilled in the art's urgent problem to be solved.
Invention content
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of Chinese pumila and " sunlight girl " American elm are close each other
This breeding garden creates technology, this method can not only make Chinese pumila and " sunlight girl " American elm steadily provides a large amount of qualities
Excellent seed, and convenient for management, control tree crown growth facilitates seed collection.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of breeding garden creates technology, which is characterized in that includes the following steps：
(1) it chooses seeds：Select pollinizers kind China's pumila and " sunlight girl " American elm.
(2) stock is colonized：It, as stock, is equidistantly colonized using " sunlight girl " American elm of common ground diameter 8-10cm；
(3) kind is grafted：By stock at 0.8-1.2m cutting strunk, it is in every line that Chinese pumila and " sunlight girl " is white
Elm is grafted；
(4) pollinizers manage：When the Chinese pumila of grafting survival grows to 40-60cm with " sunlight girl " American elm branch,
It often selects good strains in the field for seed and stays healthy and strong branch, cut off extra branch, and straight snips is carried out at 40-60cm；
(5) rejuvenation of pollinizers：After 5-6, before spring rudiment, to every plant of pollinizers in grafting or more 30-40cm
Place carries out cutting back, later again by the management operation of the pollinizers of the step (3).
The advantageous effect of said program is：Provide a kind of Chinese pumila and " sunlight girl " American elm parents each other
The breeding garden of breeding creates technology, Chinese pumila and " sunlight girl " American elm can not only be made steadily to provide a large amount of best in quality
Seed, and convenient for management, control tree crown growth facilitates seed collection.
Preferably, the spacing used is equidistantly planted as 2m*4m in the step (2).
The advantageous effect of above-mentioned optimal technical scheme is：Enough growing spaces are provided to plant.
Preferably, in the step (3) using insert the method for skin scion grafting by Chinese pumila and " sunlight girl " American elm every
Row grafting.
The advantageous effect of above-mentioned optimal technical scheme is：Cause Chinese pumila and " sunlight girl " American elm parent each other,
Between row plantation so that mutually pollination evenly.
Preferably, every plant of stock grafting 3 or more scion in the step (3).
The advantageous effect of above-mentioned optimal technical scheme is：Ensureing the nursery stock of every plant of grafting can all survive.
Preferably, it is 4-7 roots that healthy and strong branch quantity is selected and remain in the step (4).
The advantageous effect of above-mentioned optimal technical scheme is：The paper slip of health is selected and remain, further ensure that the nursery stock later stage
It grows up strong and sturdy.
In conclusion the beneficial effects of the invention are as follows：By the way that Chinese pumila and " sunlight girl " American elm interlacing are planted
Method so that Chinese pumila preferably hybridizes with " sunlight girl " American elm, makes Chinese pumila and " sunlight girl " American elm
A large amount of hybrid seeds best in quality are steadily provided, and convenient for management, control tree crown growth facilitates seed collection.
Specific embodiment
Just the specific embodiment of the present invention is described further below.
Unless otherwise instructed, the raw material employed in the present invention is commercially available or commonly used in the art, such as
Without special instruction, the method in following embodiments is the conventional method of this field.
Following embodiment is used to illustrate the present invention, but not limited to this.
Embodiment 1
It tests and is carried out in Hebei Adademy of Forestry Sciences's experiment garden, belong to the continental gas of warm temperate zone semi-moist monsoon type
It waits, experimental field topography is flat, and illumination is sufficient, and land occupation condition is superior, and soil is fertile, and quality is loose, is sandy loam type, and pH value is
6.0-8.5.It is particularly suitable for the growth of elm.
(1) it chooses seeds：Select pollinizers kind China's pumila and " sunlight girl " American elm.
(2) stock is colonized：It, as stock, is equidistantly colonized using " sunlight girl " American elm of common ground diameter 8-10cm,
