Abstract

The invention belongs to the technology of plant grafting and particularly relates to an aspen grafting method. The grafting method comprises the following steps of stock selecting, root cutting and earlier stage processing, scion selecting, scion collecting, nursery stock storing, grafting, post-grafting processing and post-emergence processing. According to the grafting method, the technology is easy to grasp, operability is high, popularization is easy; the yield of aspens cultivated through the grafting method is obviously increased, the grafting survival rate is increased to 90% or above, and artificial cultivation of aspens is achieved.

Description

The engrafting method of a kind of willow

Technical field

The invention belongs to the graft technology of plant, especially relate to the engrafting method of a kind of willow.

Background technology

Willow is the common name of Salicaceae poplar deciduous tree, the main seeds that willow is Timber stands, protection forest and turns the four sides green. Timber is multiplex makes covil construction material, production furniture, match wood, sawn timber etc., is also used as wood-based plate and fiber simultaneously, and leaf is good feed. Willow property is relatively cold-resistant, happiness light, fast-growing; Along the river two sides, hillside and Plain can grow. Timber white, light and soft, careful, proportion 0.4-0.5, for building, plate, splint, papermaking etc.; Leaf can as the feed of ox, sheep; Bud fat, inflorescence, bark can for medicinal; For the seeds building protection forest, soil and water conservation forest or turn the four sides green.

Plantation willow, not only has huge economic benefit, and has very big ecological benefits and social benefit. With the method for science plantation willow, it is possible to obtain higher income in a short time. Search great Feng Forestry Base can easily find the old and new kind willow, and the largest benefit planting willow is exactly that willow becomes a useful person soon, and felling cycle is short, and general 5-8 just can fell utilization between 12 years, and gain quick return in investment, and income is very big. People can plant in all one's life and gather in the crops willow 4-5 time of becoming a useful person, it thus is seen that it is very favourable for planting willow.

Summary of the invention

It is an object of the invention to provide the engrafting method of a kind of willow, this engrafting method technology is easily grasped, workable, is easy to promote; The willow output adopting this engrafting method to cultivate obviously increases, and the surviving rate of grafting is increased to more than 90%, it is achieved that the artificial culture of willow.

In order to realize above-mentioned purpose, present invention employs following technical scheme:

An engrafting method for willow, described engrafting method comprises the following steps:

Step one: choosing wood: select leading thread more than 8 centimetres, the basic normal willow of growth, should fill with foot winter water for selected poplar forest or fill with spring water in right amount, to ensure that stump has sufficient moisture supply;

Step 2: stump and process in early stage: annual by the end of March before stump, Cutting root height is 8-12 centimetre, and root should be intact, avoids splitting;

Step 3: scion is selected: growth selection is healthy and strong, and leaf bud is full, and without disease and pest, 1 year raw nursery stock of rugosity more than 0.6 centimetre or rudiment bar are as kind of a bar;

Step 4: scion collection: in annual 1-3 month, the long 12-15cm of scion, rugosity 0.6-0.8cm, be whittled into wedge shape by lower for scion end, inclined-plane 2-3cm, retains xylem 2mm, and the back side scrapes phloem and form layers, and scion upper end retains 2 available full buds;

Step 5: plant bar storage: take sand to bury storage, select in the shade, not easily ponding, be conducive to maintenance stablize low wet, ventilate good, the survivable location of people and animals' vehicle, dig the storage hole of dark 50-70 centimetre, it is a bundle by every for the kind bar of collection 100-200 root, hang up label, and neatly tiltedly stand in hole by the sequencing adopting bar, want one layer of wet husky one layer of kind bar during operation, bury husky height GPRS making kind of a bar top 1/4-1/5 part expose husky face and be advisable;

Step 6: grafting: adopt cortex grafting, annual April is upper, the middle ten days carry out grafting, 1 scion of the stump and grafting of below diameter 10cm, 2 scion of the stump and grafting of diameter 10-15cm, 3 scion of the stump and grafting of diameter 15��20cm, stump and grafting 4-5 scion of more than diameter 20cm;

Step 7: grafting aftertreatment: to be smeared sternly with yellow mud in time by scion top, scion and stock joining place gap after grafting, buries stump and scion sternly with clean loose wet soil, and thickness exceedes scion top 5-10cm;

Step 8: aftertreatment of emerging: Graft to be removed the germinating twig on stock sprout tillers and scion treelet after being unearthed in time, when Graft grows to 1m, training first time soil, is highly not less than 50cm; When Graft grows to 2m training second time soil, be highly not less than 80cm, mid-July the Graft bondage on each stump to together.

Further, it is whittled into the little light face of 3-4cm when Cutting root height is no more than 5cm described in step 2 at the phloem of grafting part and xylem place, makes that interface is clean and form layers is obvious.

Further, the principle of " adopt afterwards first with " or " the rear use first adopted " when kind of bar is taken in step 5 grafting, should be followed.

Compared with prior art, the present invention has following advantage:

Engrafting method technology of the present invention is easily grasped, workable, is easy to promote; The willow output adopting this engrafting method to cultivate obviously increases, and the surviving rate of grafting is increased to more than 90%, it is achieved that the artificial culture of willow.

Embodiment

It will be understood by those skilled in the art that, technology disclosed in following examples represents the technology playing good action in the practice of the invention that the present inventor finds. But, disclosed specific embodiments can be made many changes, and still obtain same or similar result, and not depart from the spirit and scope of the present invention.

Embodiment 1:

Step 2: stump and process in early stage: annual by the end of March before stump, Cutting root height is 8-12 centimetre, and root should be intact, avoids splitting, the little light face being whittled into 3-4cm when root height is no more than 5cm at the phloem of grafting part and xylem place, makes that interface is clean and form layers is obvious;

Step 5: plant bar storage: take sand to bury storage, select in the shade, not easily ponding, be conducive to maintenance stablize low wet, ventilate good, the survivable location of people and animals' vehicle, dig the storage hole of dark 50-70 centimetre, it is a bundle by every for the kind bar of collection 100-200 root, hang up label, and neatly tiltedly stand in hole by the sequencing adopting bar, one layer of wet husky one layer of kind bar is wanted during operation, bury husky height GPRS making kind of a bar top 1/4-1/5 part expose husky face and it is advisable, the principle of " adopt afterwards first with " or " the rear use first adopted " when kind of bar is taken in grafting, should be followed;

Above-described embodiment is that the present invention preferably implements mode; but embodiments of the present invention are not restricted to the described embodiments; the change done under the spirit of other any the present invention of not deviating from and principle, modification, replacement, combination, simplification; all should be the substitute mode of equivalence, it is included within protection scope of the present invention.
