Abstract

The invention discloses a navel orange grafting method. The method comprises the steps as follows: 1) rootstock and scion selection, wherein a navel orange sapling of 4 to 5 years old is selected as a naval orange rootstock, and a fruit-bearing blood orange branch is selected as a scion; 2) grafting method, wherein selection of 20-25 secondary branches for grafting is appropriate, others are cut off, the number of grafted buds is 40 to 50, grating ought to be performed in October after fruits of first-year quinces are picked, excellent aged and vigorous navel orange autumn shoots are selected, and grafting is completed with a bud whole-packaging method; 3) binding; 4) grafting management after grafting plant, wherein from the second year after fruit bearing, renewal of fruiting branches is performed. The navel orange grafting method has the advantages that renewal of fruiting branches is performed through blood orange branch and naval orange grafting, so that the illness rate of naval orange trees is low, the fruit bearing age is long, and the good fruit rate is high.

Description

The engrafting method of Citrus sinensis Osbeck

Technical field

The invention belongs to the technical field of the cultivation of Flos lupuli (Flos Humuli Lupuli), Fructus Vitis viniferae, fruit tree or similar trees, specifically the engrafting method of a kind of Citrus sinensis Osbeck.

Background technology

The planting type of existing Citrus sinensis Osbeck, is that open country is planted mostly, and after open country plants, period of maturation is substantially in mid or late May, such as Fructus Persicae pole early 518 kinds, it is simply that ripe May 18, hereafter listing concentrated successively by each kind Fructus Persicae, because its planting technique is simple, extensive management, so benefit is general, planting fruit trees family is sold less than good price, after the universal fruit tree in greenhouse cultivation technique in the north, Fructus Persicae Time To Market is only advanced by about one month (April) on original basis; Additionally the grafting of existing Citrus sinensis Osbeck is generally adopted branch and Fructus Persicae tree grafting, such grafting branch out of other raw kind of the close family of habit, and general growing power is not particularly strong; The Fructus Persicae mouthfeel grown is bad, and sick rate is high, and Fructus Persicae growth year is short.

Summary of the invention

In view of this, it is an object of the invention to provide the engrafting method of a kind of Citrus sinensis Osbeck, the engrafting method of this Citrus sinensis Osbeck passes through blood orange branch and Citrus sinensis Osbeck grafting, carries out the renewal work of fruit-bearing shoot cluster, and the sick rate of Citrus sinensis Osbeck tree is low; Bearing fruit a year limit for length, percent rate of high quality fruit is high.

In order to achieve the above object, the engrafting method of a kind of Citrus sinensis Osbeck of the present invention, comprise the following steps:

1) selection of stock, scion: Citrus sinensis Osbeck Root-stock selection is the Citrus sinensis Osbeck seedling of life in 4～5 years, amputates and stays trunk not stay branch; The selection of scion: select the blood orange branch born fruit, grows vigorous and without pest and disease damage;

2) engrafting method: the main skill of pair choosing grafting is advisable at 20～25, and other is wiped out, transfers budding amount at 40～50; The time of grafting should carry out in the October after temperature Citrus chachiensis Hort. fruit picking in the first year, chooses the excellent Citrus sinensis Osbeck autumn growth of aging stalwartness, takes the method for full bag bud to complete,

3) bondage: vinasse slag, cow dung, trace element (ferrum, sulfur, copper, manganese, selenium) mixing water are formed thick shape, spreads upon on gauze or cotton, the gauze containing thick shape nutritive mud or cotton are strapped in stock and scion junction;

4) grafting management after grafting plantation: the Second Year born fruit rises, carry out the renewal work of fruit-bearing shoot cluster, in two Citrus sinensis Osbeck pair major branches that grafting updates on same former temperature Citrus chachiensis Hort. pair major branch, a selected secondary major branch is fruit-bearing shoot cluster then, only take out and send out the spring tip, control all of summer, autumn growth, promote many results; And the Citrus sinensis Osbeck pair major branch after another grafting renewal is as nutrition branch group then, do not bear fruit then, the erase all of spring tip and alabastrum, cultivate to take out and send out summer shoot and an autumn growth, become the fruit-bearing shoot cluster of next year.

Further, in step 3) in, every 7 days to 10 days, spray sticky rice syrup juice at stock and scion bondage place.

Further, in step 3) in, in sticky rice syrup juice, Oryza glutinosa is 1:5～10 with the ratio setting of water.

Further, described sticky rice syrup juice by Oryza glutinosa and water boil, endure what rotten rear dilute was formed.

Further, described sticky rice syrup juice is formed by Oryza glutinosa grinds and the rotten rear dilute of decocting in water.

The beneficial effects of the present invention is:

The engrafting method of Citrus sinensis Osbeck of the present invention passes through blood orange branch and Citrus sinensis Osbeck grafting, after grafting, grafted portion carried out bondage fertilising, shelter from heat or light and keep off the rain, improve the survival rate of grafting branch, manage again through preferentially bud grafting, the Citrus sinensis Osbeck making grafting is longer 4～5 years than the general Citrus sinensis Osbeck tree life-span, and the sick rate of Citrus sinensis Osbeck tree is low; Bearing fruit a year limit for length, percent rate of high quality fruit is high.

Detailed description of the invention

The engrafting method of a kind of Citrus sinensis Osbeck of the present invention, comprises the following steps:

2) engrafting method: scion should gather grafting on the same day same day, adopts abdomen to amplexiform, and graft survival rate is high; Grafting time is for by the end of March at the beginning of 5 months, and temperature is stable to be robbed calm and cloudy grafting and can significantly improve graft survival rate between 15-25 DEG C,

4) grafting management after grafting plantation: the Second Year born fruit rises, and will carry out the renewal work of fruit-bearing shoot cluster, otherwise there will be previously described variety deterioration problem. The method updated is, in two Citrus sinensis Osbeck pair major branches that grafting updates on same former temperature Citrus chachiensis Hort. pair major branch, a selected secondary major branch is fruit-bearing shoot cluster then, only take out and send out the spring tip, result in the spring tip, control all of summer, autumn growth, many seldom have summer, autumn growth to take out to send out because fruit-bearing shoot cluster is born fruit, promote many results, and the Citrus sinensis Osbeck pair major branch after another grafting renewal is as nutrition branch group then, do not bear fruit then, the erase all of spring tip and alabastrum, cultivation is taken out and is sent out summer shoot and autumn growth, becomes the fruit-bearing shoot cluster of next year.

What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
