Abstract
The invention discloses a method for raising seedlings of golden bough goldenrain tree by grafting. The method comprises the following steps: (1) selecting scions; (2) storing the scions; (3) making the scions; (4) selecting and cutting a tree stock; (5) jointing or inserting; and (6) managing grafted seedlings. The method for raising the seedlings by grafting disclosed by the invention has the advantages that: firstly, the problem of difficult vegetative propagation of the golden bough goldenrain tree can be solved; secondly, excellent ornamental property of leaves and branches of the golden bough goldenrain tree is maintained, and the growth adaptability and stress resistance of the golden bough goldenrain tree are improved; and thirdly, seedling formation speed is fast, the tree stock is available, and only a small segment of branch is taken as one scion, thus propagation period is short, propagation coefficient is high and massive seedlings can be obtained. The method for raising the seedling of golden bough goldenrain tree disclosed by the invention has important popularization value in rapid propagation of the ornamental nursery stock of a goldenrain tree.
Description
Technical field
The present invention relates to a kind of woody plant asexual reproduction method, specifically relate to a kind of gold branch Luan Shu grafting seedlings-growing method.
Background technology
Gold branch Luan Shu is a mutation of the natural bud mutation of Luan Shu (Koelreuteria integrifoliola), and its young leaves is orange colour, and autumn leaves is completely set golden yellow brilliance, and winter, branch also was golden yellow, had much ornamental value.In order to keep the distinctive ornamental value of gold branch Luan Shu, must use asexual reproduction method and breed its seedling, gold branch Luan Shu branch cutting and root are inserted the very difficulty of taking root all, and reproductive efficiency is low.Through gold branch Luan Shu grafting with the propagation method of Luan Shu as stock; The merit that can keep gold branch Luan Shuye and branch to view and admire; Improve the adaptability and the resistance of gold branch Luan Shu growth, shortened the breeding cycle, greatly improved the reproduction coefficient of golden branch Luan Shu.
Summary of the invention
In order to solve the quick breeding of gold branch Luan Shu, the object of the present invention is to provide a kind of easy and simple to handle, can keep good characteristic that a gold Luan Shu views and admires and the propagation method of rapid Cheng Miao.
The present invention realizes through following technical scheme:
A kind of gold branch Luan Shu grafting method is characterized in that it is made up of the following step:
(1) choosing of scion: winter to early spring is the clip branch on robust growth, the gold branch Luan Shu elite stand that do not sprout as yet, and branch is cut into 15~25cm, wraps up with wet cloth, and is subsequent use;
(2) storage of scion: place the bulk container that is filled with water to heat in the container of splendid attire paraffin; When treating water temperature rise to the 100 ℃ left and right sides; One in the branch of step (1) is immersed taking-up immediately in the paraffin that melts; Turn around again and dip in the other end, make the appearance of whole scion all cover the very thin paraffin of one deck, be placed on the low temperature place refrigeration about 5 ℃ then.Subsequent use;
(3) making of scion: the branch after will preserve spring is cut into the long scion of 5~8cm, and the scion bottom is whittled into wedge shape, and according to the rugosity of stock, when stock was thick, scion can be cut thickly slightly, and when stock was thin, scion can be cut thin.Subsequent use;
(4) selection of stock with cut anvil: 3~4cm cuts off at the place Luan Shu stock of will not sprout apart from ground, scabbles section, and the downward vertical cut at the edge of xylem will impose uniformity without examining individual cases, and kerf width and scion equal diameters reach 2~3cm deeply; Begun to sprout like stock, 3~4cm cuts off at the place apart from ground with stock, scabbles section and gets final product, and is for use;
(5) engage or insert: the stock of not sprouting can be used cut-grafting, step (3) scion inserting step (4) stock otch, uses the bottom-up whipping of plastic tape tight then; For the stock that begins to sprout, the stock cortex is vertically cut an osculum, scion is inserted from the stock otch along xylem and in the middle of the phloem, whips closely with plastic tape again.
(6) management of grafting: be carried out to biopsy after the grafting in 10~15 days, the bud in the scion keeps fresh or germination and growth then shows and become alive, and survival rate can reach 80~90%.In time wipe out branch and the root sprout tillers branch sprouted on the grafting stock, guarantee the nutrition supply and the growth of scion.The scion sprout growth is removed the bondage of plastic tape after 1~2 month.Should keep the moistening of field soil between the grafting healing stage, grafting can carry out management such as normal field weeding, fertilising after becoming to live.
Further, 1 year living diameter that the said scion of step (1) is taked in tree crown, clip growth in top is enriched is healthy and strong at 1~2.5cm, the full branch of sleeping bud;
The time of the said grafting of step (3) 15 days~March 25 March in spring the Luan Shu nursery stock do not sprout as yet or carry out when being about to sprout; Scion cut get be with the scion bottom from apart from the nearest back side, bud position of lower cut, with grafting knife parallel end that is cut to the scion axis downwards when inscribe reaches xylem, tangent plane is grown 3~5cm, subsequently scion bevel offside is splayed into 0.5~1.0cm inclined-plane.Scion cut thickness generally at 0.3~0.5cm;
The said stock of step (4) is selected 1~2 year living Luan Shu seedling of the leading thread 2~4cm of robust growth, no damage by disease and insect;
The mode of the said grafting of step (5) is the big bevel of scion inwards, inserts the stock otch, and is inserted into the end, makes scion aim at snap with the cambium of stock.If anvil, fringe do not wait slightly, can aim at cambium on one side; For beginning the stock of leading thread more than 2cm of sprouting; The stock cortex is vertically cut an osculum; Length is 1/2~2/3 of scion length, inserts facing to xylem the long bevel of scion from the stock otch along xylem and in the middle of the phloem, and makes the scion back side aim at stock otch center; White 0.5~1.0cm is stayed on bevel top during insertion, is beneficial to the healing of callus growth and otch.
Beneficial effect of the present invention: adopt grafting seedlings-growing method of the present invention to solve the vegetative problem of golden branch Luan Shu, the merit that keeps gold branch Luan Shuye and branch to view and admire improves the adaptability and the resistance of gold branch Luan Shu growth; Because the stock ratio is easier to obtain, and a bit of branch is only used in scion, takes this stock grafting method; The survival rate of seedling propagation is up to more than 85%, and breeding period is short, and reproduction coefficient is high; Can emerge in a large number, the quick breeding of Luan Shu being viewed and admired nursery stock has important promotional value.;
