Abstract
The invention provides a seedling raising method for promoting Pterocarpus santalinus to form heartwood as soon as possible. The Pterocarpus santalinus is the most precious redwood tree species, but the heartwood is formed late, and wood forming period is long. According to the seedling raising method, a one-year-old or two-year old plant of Pterocarpus macarocarpus is selected as a stock, a one-year-old branch of P. santalinus is used as a cion, single bud branch grafting in a period of dormancy is carried out, and the plant survives and grows well. Detection results show that after the Pterocarpus santalinus cultivated by the technical method is planted, the heartwood is remarkably promoted to be formed as soon as possible, and the Pterocarpus santalinus is suitable for being popularized and used in tropical precious timber tree species breeding and cultivation.
Description
Technical field
The invention belongs to Precious Timber Species reproduction technique field, and in particular to one kind promotes red sandalwood
(Pterocarpus santalinus) forms the method for culturing seedlings of heartwood early.
Background technology
The timber (heartwood) of red sandalwood is uniquely to be referred to as the timber of narra in redwood timber, the most precious.But.
The red sandalwood heartwood formation phase is very long, is typically just initially formed after 20 years.Burma padauk (P.macarocarpus) and wingceltis
Fragrant red sandalwood belongs to Pterocarpus together, and form is graceful, and the speed of growth is the Pterocarpus tree of heretofore known early start formation heartwood quite
Kind, 18~20 years it is raw when heartwood account for wood cross section and accumulate more than 75%, other Pterocarpus such as red sandalwood cannot be compared,
This proterties is very excellent.In view of this, we, with Burma padauk as stock, are made in redwood kind seedling-wood breeding with red sandalwood
Scion has carried out Experiment on graft reproduction, succeeds.Testing result shows, by this kind of red sandalwood nursery stock of method cultivation,
Heartwood is remarkably promoted after cultivation to be formed early.
The content of the invention
It is an object of the invention to provide a kind of method for culturing seedlings for promoting red sandalwood to form heartwood early, the method can show
Write and promote red sandalwood heartwood to be formed early.
The method for culturing seedlings for promoting red sandalwood to form heartwood early of the present invention, comprises the following steps：
A. morning is formed with heartwood, 1~2 year raw plant of the Burma padauk (P.macarocarpus) of cycle is short of becoming a useful person makees stock,
Scion develops clip on 1 year substantial raw branch from red sandalwood (Pterocarpus santalinus)；
B. in the rest period in annual 1~2 month, grafting is carried out in cut-grafting mode；
C. grafting and breeding is carried out in seedling raising greenhouse or greenhouse.
According to the further feature of method for culturing seedlings of the present invention, in the step B, the grafting, including following step
Suddenly：(1) cut anvil at more than neck 5~7cm, in the straight partial application of edge longitudinal of stock cross section, incision length is slightly longer than scion
Bevel length, width are consistent with scion diameter；
(2) scion base portion two bevels that are whittled into that one is long and the other is short；
(3) scion is cut at about 1cm above full bud, 5~6cm of length；
(4) scion bevel long is injected into stock otch, alignment scion forming layer and stock forming layer inwards；
(5) graft union and scion are tied up sternly with plastic film strip, only dew is buddered, and transposing fringe is kept off during operation.
According to the further feature of method for culturing seedlings of the present invention, in the step (1), incision length is about 3cm.
According to the further feature of method for culturing seedlings of the present invention, in the step (2), the bevel long is to ream 1/
The bevel of more than 3 xylems, is about 3cm.
According to the further feature of method for culturing seedlings of the present invention, in the step (2), the short bevel is about l
cm。
According to the further feature of method for culturing seedlings of the present invention, in the step B, the grafting and breeding includes following
Step：First month after grafting, greenhouse or the greenhouse Shading net covering of 50% sunshade rate；Hereafter, it is transitioned into full exposure cultivation；And
When the rudiment erased on stock；In March after grafting, release the plastic sheeting of colligation；Cultivate while outdoor garden is transferred to after June, next year
Just go out garden and supply cultivating large seedling.
First passage selection heartwood of the present invention forms early and fast Burma padauk for stock grafting is bred, and can remarkably promote most
The heartwood development of precious redwood seeds --- red sandalwood, is greatly enriched Precious Timber Species cultivation theory and technology,
With prominent more practical value and scientific meaning, do not report both at home and abroad.
Brief description of the drawings
Fig. 1 is the photo that grafting promotes red sandalwood heartwood to be formed early.It is followed successively by from top to bottom：The wingceltis of the same period non-grafting
The red sandalwood of 18 months after fragrant red sandalwood, Burma padauk stock, the red sandalwood of grafting, grafting.
Specific embodiment
Red sandalwood seedling grafting mating system of the present invention described below.
1~2 year raw plant of selection Burma padauk (Pterocarpus macarocarpus) is stock, with red sandalwood
(P.santalinus L.f) 1 year raw branch makees scion, carries out rest period simple bud scion grafting, and the red sandalwood heart is remarkably promoted in cultivation
Material is formed early.
Scion：1 year raw branch of red sandalwood.
Stock：1~2 year raw nursery stock of Burma padauk.
Grafting period and method：Optimal grafting period is 1~2 month of rest period, and optimal grafting method is cut-grafting, is being kept away
Grafting and breeding is carried out in the nursery canopy room of rain.
1) cut anvil at more than neck 5~7cm, in the straight partial application of edge longitudinal of stock cross section, the length of otch is slightly longer
It is consistent with scion diameter in scion bevel length (3cm or so), width.
2) scion base portion two bevels that are whittled into that one is long and the other is short；Bevel long reams more than 1/3 xylem, is about 3cm；It is short to cut
Face is about 1cm.
3) scion 6cm long or so, cuts at about 1cm above full bud
4) scion bevel long is injected into stock otch, alignment scion forming layer and stock forming layer inwards.
5) tied up sternly with grafting plastic film strip.Transposing fringe is kept off during operation.
Managed after connecing：Rear first month is connect, nursery stock must use the Shading net covering of 50% sunshade rate, other management are with conventional.
In time except the rudiment sprouted on stock.Into September part, cultivate with being transferred to outdoor garden, garden is gone out at the beginning of next year and supplies cultivating large seedling.
It is stock grafting red sandalwood altogether with Burma padauk (P.macarocarpus) in experimental study of the invention
270 plants, cut-grafting, cleft grafting, cortex grafting strain number are respectively 110,80,80 plants, the survival rate after grafting 5 months is respectively 89.3%,
82.5%th, 85.0%, can be healed earlier with the survival rate highest of cut-grafting, and interface.Therefore, technical method of the invention can
By, it is ripe, simple and easy to do, remarkably promoted after cultivation red sandalwood heartwood formed development, with prominent application value.
