Abstract

The invention discloses an osmanthus fragrans grafting method, and belongs to the technical field of osmanthus fragrans planting. The method comprises the steps of (1) preparation of a grafting tool; (2) selection of grafting time: time between the end of May and the beginning of June every year is selected; (3) selection and preparation of rootstocks; (4) selection of scions; (5) grafting: a cleft grafting method is adopted; (6) treatment of underwood; (7) growth maintenance; (8) pruning and reshaping. The method has the advantages that strong nonflowering solid wood seedlings are fully used for grafting thunbergii or orange osmanthus as the rootstocks, the cleft grafting method is used for grafting, the existing growth advantages of the solid wood seedlings are fully utilized, and meanwhile, the solid wood seedlings are grafted, so that the rootstocks and the scions are high in affinity, the healing time of grafting unions is short, growth maintenance is more facilitated, and the finally grafted osmanthus fragrans is high in quality.

Description

A kind of sweet osmanthus grafting method

Technical field

The present invention relates to sweet osmanthus planting technology field, be specifically related to a kind of sweet osmanthus grafting method.

 

Background technology

Sweet osmanthus is green throughout the year, flourishing, fall flowering, sweet perfumes are diffused all around, now generally becomes the main seeds of urban road, gardens, garden, residential quarter greening, it is not only famous and precious ornamental plantation flowers and trees, and be perfume industry, food industry, medicinal material industry and the valable starting materials of light industry, sweet osmanthus has certain resistance to pernicious gas etc., is the good flowers and trees of one of industrial and mining area greening, sweet osmanthus also has certain medical value, and its flower can preventing phlegm from forming and stopping coughing; Really, for cold of insufficiency type and stomachache; Root, can wines used as antirheumatic, loose cold.

The cultivation of sweet osmanthus is generally divided into seeding method, grafting, cuttage and the planting of layer, the sweet osmanthus of large stretch of seeding and seedling raising, the seedling that certain proportion is not bloomed can be there is, these sweet osmanthus nursery stocks that can not bloom, if can not utilize, can only abandon, so not only waste resource, and subsequent treatment takes time and effort.

Summary of the invention

The object of the present invention is to provide a kind of sweet osmanthus grafting method, its solid wood seedling of not blooming making full use of growing way stalwartness is as stock grafting gold osmanthus or orange osmanthus, and because of grafting on seedling, affinity is strong, and grafting sweet osmanthus quality is high.

Technical solution problem of the present invention adopts following technical scheme:

A kind of sweet osmanthus grafting method, its step is as follows:

(1) grafting tool prepares: grafting knife, grafting knife are sterilized, standby mulch film one section, sliver a bundle;

(2) grafting time: choose at the beginning of 5 the end of month to 6 month of 1 year;

(3) selection of stock and preparation: the lifes in 8 ~ 9 years choosing robust growth are not bloomed solid wood seedling, cleft graft is adopted to process: first exerting oneself girdling stock branch with grafting knife apart from 5 centimetres, ground eminence, cut off with sharp scissors again, stock branch otch wants flat smooth, with grafting knife vertical incision in stock side (slightly xylem is about 1/5 ~ 1/4 of diameter on cross section). and dark about 2 ~ 3 centimetres;

(4) the choosing of scion: sweet osmanthus has the kinds such as Jin Gui, silver-colored osmanthus, orange osmanthus, Osmanthus fragans, when selecting seedling to do stock grafting, considers the advantage of its affinity, preferentially chooses golden osmanthus or orange osmanthus as grafting maternal plant;

The stalwartness of life in fully lignified 1 ~ 2 year on adult maternal plant is chosen in scion, anosis branch is advisable, the rugosity of scion and the rugosity of stock will match, when cutting scion, scion retains 2 ~ 3 complete full buds, the back side, bud position grafting knife nearest apart from lower cut for scion is slightly reached xylem to inscribe, parallelly with scion axis be downwards immediately cut to the end, long 2 ~ 3 centimetres of tangent plane, the less inclined-plane of 0.8 ~ 1 centimetre is whittled in rear end, growth hormone liquor is immersed 2 hours in scion cutting end;

(5) grafting: adopt cleft graft, long for the scion of cutting bevel is inwardly inserted in stock otch and (once inserts, damage does not form layer), the formation layer of scion is aimed at the formation layer of stock touch, the degree of depth that scion is inserted is exposed 0.5 cm with scion bevel upper end and is advisable, favourable healing survives, if stock otch is wide, can aim at while form layer, docking, fixing rear sliver ties up closely from bottom to top, can have concurrently and formation layer is touched and moisture-keeping function, simultaneously can at interface sealing clay grafting wax, or indigenous method is buried in employing, moisturizing object is reached to reduce moisture evaporation,

(6) tiller process: after grafting binding completes, prunes away the stock twig of interface surrounding, all sprout tillers of grafting root of will erasing in time before and after scion rudiment, thus promotes the growth of scion sprouting;

(7) growth is safeguarded: will regularly carry out between the scion budding period applying fertilizer, watering and deinsectization, and after grafting mouth is completely closed, can send the sliver of binding, after a period of time, last solution is tied up again;

(8) trimming and finishing: after scion fusion growth half a year, can carry out trimming and finishing, namely a plant height quality sweet osmanthus completes.

The present invention is compared with existing sweet osmanthus graft technology, its beneficial effect is: make full use of the solid wood seedling of not blooming of growing way stalwartness as stock grafting gold osmanthus or orange osmanthus, cleft graft is adopted to carry out grafting, make full use of the existing growth vigor of solid wood seedling, simultaneously because of grafting on seedling, the affinity of stock and scion is strong, and grafting mouth healing time is short, more easily grow maintenance, final grafting sweet osmanthus quality is high.
