Description

The method that the grafting then of a kind of ginkgo is born fruit then

technical field:

The present invention relates to the grafting field of fruit tree woods, be specifically related to the technology that a kind of ginkgo grafting is born fruit then.

background technology:

Ginkgo (Ginkgo biloba Linn.) is Ginkgoaceae Ginkgo deciduous tree.It is the most ancient gymnosperm carrying over after quaternary glacier motion, also be one of very precious in the world seeds, by scientist, be called " living fossil ", " botanic panda ", for China special product seeds, mainly be distributed in Shandong, Zhejiang, Anhui, Fujian, Jiangxi, Hebei, Henan, Hubei, Jiangsu, the provinces such as Hunan, Sichuan, Guizhou, Guangxi, Guangdong, Yunnan, Taiwan.Ginkgo is intolerant tree species, deep-rootedness, adaptability to weather, soil is wider, its cultivation area is very wide, and north is from Shenyang, northeast, and south reaches Guangzhou, from the east of East China height above sea level 40-1000 meter band, southwest to Guizhou, all there is cultivation in From Western Yunnan height above sea level area 2000 meters below, take seeding as object, or does Landscape Tree Species cultivation.

Ginkgo whole body is " treasured ", its seed edible (many foods are easily poisoning) and medicinal; Leaf can be made medicinal and insecticide processed, also can make fertilizer; The meat exosper of its seed is containing ginkgolic acid, gingko alcohol and bilobol, poisonous, can used as pesticides use, there is the effect of control plant pest.Ginkgo also has ornamental value, can be used for the desirable seeds of afforestation, trade, highway, farmland protection, shelterbelt, is listed in the large long-lived ornamental tree species of China four (pine, cypress, Chinese scholartree, ginkgo).

summary of the invention:

A kind of method that the object of the present invention is to provide ginkgo grafting to bear fruit then, for bonsai and fruit tree manufacturer application.

The present invention adopts following technical scheme to realize its goal of the invention: the method that the grafting then of a kind of ginkgo is born fruit then, it completes its grafting by stock selection 1, scion selection 2,

grafting

3,4 four steps of management.

Step 1: stock is selected

Choosing biennial above ginkgo or stub is stock, and requiring stock branch diameter is 2cm left and right.

Step 2: scion is selected

Selection is grown and is enriched, internode is shorter and do scion with the branch of a large amount of sturdy short buds, branch footpath 1-1.5cm; The busy grafting of the scion of 7-10 days clips or the same day and grafting be not complete before grafting, scion should be stored in clean moistening river sand standbyly, and the water content of sand is 5-6 ﹪, or scion is put into refrigerator storage cabinet with plastic bag sealing and preserve.

Step 3: grafting

Grafting adopts whip grafting to carry out, and grafting time is advisable between early April with the early March in mid-September-early October or spring.

Step 4: management

After grafting survival, when scionwood is bloomed, gather in time the staminiferous plant pollen of ginkgo, female fringe of result is pollinated, after scion is fully healed, should remove in time film strip, and will carry out conventional fertilizing management to grafting.

Owing to having adopted above technical scheme, the present invention has realized its goal of the invention preferably, and when the method that the grafting of this ginkgo is born fruit then operates, input cost is low, Ginkgo Growing speed is fast, economic worth is large, and then with regard to energy result, has very high ornamental value and economic worth.

accompanying drawing explanation:

Fig. 1 is grafting method flow chart of the present invention.

Description of reference numerals is shown in specification last page form.

embodiment:

Below in conjunction with embodiment, summary of the invention is described further:

embodiment 1:

From summary of the invention: the method that the grafting then of a kind of ginkgo is born fruit then, it by stock select 1, scion selects 2, grafting 3,4 four steps of management complete its grafting.

Stock requires as biennial above ginkgo or stub, and stock branch diameter is 2cm left and right, if stock branch excessively thick (as ancient tree stake) can first cut short, grafting on the shoot of cultivation.

Select robust growth, result elite stand without damage by disease and insect, sunny side is worked as in middle and upper part in elite stand tree crown periphery, clip is grown and is enriched, internode is shorter and with a large amount of sturdy short buds, the branch of branch footpath 1-1.5cm, the same day or front 7-10 days in grafting shear, gathering scion should carry out at cloudy day or morning, connect or grafting after 7-10 days, before grafting, the busy grafting of the scion of 7-10 days clips or the same day and grafting are not complete, should be bundled into 10-20 root tate, then one deck scion, one deck profit sand, staggered stacking is stored in clean moistening river sand standby, the water content of sand is 5-6 ﹪, or scion is put into refrigerator storage cabinet with plastic bag sealing and preserve.Each standby scion should connect in two weeks.

Early March in mid-September-early October or spring is advisable between early April, best with the scion grafting of the 3-4 month in spring.

Grafting adopts whip grafting: first by ginkgo seedling at 5cm place straight snips overhead, choose round and straight, smooth one side is made cut sides, stock tangent plane is slightly cut to a little, expose and form layer, aligning exposes cambial inner side, with cutter xylem slightly downwards, vertical incision 2cm is dark, then choose one small and weak in the scion of stock, at 1cm above sturdy short bud, cut off at place, retain 1-2 bud, at the 1cm place, the back side that has bud, down cut and get the long tangent plane of about 2cm, tangent plane is straight, the scion of overturning again, on the interface inclined-plane of splaying, the scion of cutting is inserted in stock, require scion to align with the formation layer of stock, at least alignment one side, then with film strip, tie.

After grafting, often touch except the rudiment on stock.After grafting survival, when scionwood is bloomed, to gather in time the staminiferous plant pollen of ginkgo, with writing brush to female fringe of result be pollinated (key: be pollinated not in time just can not bear fruit), 7-8 month after scion is fully healed, when the interface of film strip binding expands, should remove in time film strip, and will carry out conventional fertilizing management to grafting.By above management, the ginkgo branch of grafting then, the fruit after blooming just can keep, and enters autumn, just can picking fruit, Ginkgo bonsai in this way, just can enjoy a basin leaf, really, type tool good beautiful bonsai.
