Abstract
The invention provides a method for prolonging the life cycle of a peach tree, comprising the steps that a growing root is grafted onto the side root of an old peach tree, and a new small sapling grows at the grafting location; secondly, the branches of the old peach tree are gradually removed, so that growing space is made for the growing of the small sapling, and the small sapling gradually grows into a new peach tree; and thirdly, when the new peach tree grows to have a capability of providing enough nutrients to the root, other parts of the old peach tree except the root are removed. The root of the old peach tree is used for nourishing the new outgrowing small sapling; the old peach tree continues to provide the root with the nutrients for the survival of the root; when the small sapling grows into the new peach tree, the root of the old peach tree gradually becomes the root of the new peach tree; and at the moment, the old peach tree is cut away, and the new peach tree replaces the old peach tree.
Description
Technical field
The present invention relates to technical field of plant culture, especially relate to peach life cycle prolongation method.
Background technology
Peach be in the woody fruit life-span the shortest fruit tree, from the germination of peach, growth, result to decline, life cycle south is no more than 20 years, the north is no more than 30 years.Deduct first three rear 5 years nurturing period and decline phase, the full bearing period is only about 10 years.The such income in peach garden every year will be seldom.
And peach also has characteristics to avoid exactly ground, can not continuous cropping.If continuous cropping, the treelet phase is just obviously weak, especially performance growth retardation in initial several years, and leaf chlorosis, part is withered, and gummosis appears in the branch trunk position that has, and yield poorly or without receiving phenomenon, even plants unsuccessfully in whole peach garden.Main cause is that the undesirable root of peach contains a large amount of amygdalins, can secrete a kind of amygdalin enzyme in the microorganism take amygdalin as nutrition, through the effect of hydrolysis and enzyme, amygdalin is decomposed into the materials such as benzaldehyde and cyanic acid.Its molecular formula is as follows: C
20H
27NO
11+ 2H
2O---→ C
6H
5CHO+2C
6H
12O
6+ HCN to the breathing generation obstruction of peach root, thereby causes the peach root rot, causes position growth on the ground weak, and straight deadly dying is so peach can not continuous cropping.After the peach death, need to change the place plantation, the life cycle that adds peach is short, so peach needs constantly to transplant, waste time and energy, and greatly increased cost, 60,000 mu of peach gardens of Ningbo municipalization, need cost (every mu peach seedling 40 strains * 2 yuan=80 yuan+every mu digging machine take 500 yuan+labour cost 300 yuan) 900 yuan * 6 ten thousand mu=5,400 ten thousand yuan to will again building the garden plantation once 20 annual periods one.And again change the first three years in place, and belong to the nurturing period in peach garden, there is not output.
We find under study for action, and root still has vitality and gloss is prosperous tender under its soil when old peach decline.If but directly tree crown is cut down, then tree root can not get nutrition, also can be withered, therefore withered tree root can affect again the plantation of new peach, how to utilize the root of veteran to cultivate new peach and has become a technical barrier.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of peach life cycle prolongation method is provided, can greatly prolong the life cycle of peach.
For solving the problems of the technologies described above, the present invention is solved by following technical proposals: peach life cycle prolongation method comprises following steps: one: grafting growth root on the lateral root of old peach, the little sapling that the grafting director makes new advances; Two: old peach is removed branch gradually, abdicate the space of little tree seedling growth, little sapling grows up to new peach gradually.
Three: long when can satisfy tree root nutrition to new peach, the part of old peach except tree root removed.
Utilize the tree root of old peach, nourish the little sapling that newly grows, old peach continues to provide nutrition to tree root, keep the existence of tree root, after little sapling grows up to new peach, the tree root of old peach just becomes the tree root of new peach, at this moment older peach is cut down, new peach has just substituted the position of old peach, simultaneously, substitutes in the old peach process in new peach, early stage, old peach produced peach, mid-term, old peach and new peach produced peach together, and the later stage, new peach substituted old peach product peach, and the output of peach can not be subject to too large impact all the time.Because the tree root life-span of peach is longer than peach itself far away, the life-span of general tree root can reach more than 40 years, calculated by minimum 40 years, deduct first three rear 5 years nurturing period and decline phase, can reach 32 years the full bearing period, greatly improved the income in peach garden, and reduced and repeatedly transplanted the cost that peach produces.
In the technique scheme, preferred, in the step 1 growth root select old peach on the sunny side the lateral root of a side carry out grafting.Day side sunlight is good, and well developed root system is grown fast, so the growth root survival rate of grafting is high and the ratio of growing up is very fast.
In the technique scheme, preferred, described old peach begins the described growth root of grafting in the age of tree in 14 years to 15 years.The age of tree of old peach is too large, at this time carries out grafting again, and the old peach of possibility is dead, and new peach does not also begin the result, will affect like this output of peach.
In the technique scheme, preferred, length is progressively removed the branch of old peach year by year to 2-3 after described little sapling survives.
In the technique scheme, preferred, the concrete method that described old peach is removed guarantee stub below soil, and the stub under soil is carried out the lime spraying for saw blade part saw more than the old peach ground being removed in the step 3.The winter that prevents various insects hides and the termite intrusion, and new peach is exerted an influence.
In the technique scheme, preferred, after the described growth root of grafting, 1 year can not be to fertilize with growth root place, inherence.The growth root that can prevent grafting is subjected to fertilizer damage.
In the technique scheme, preferred, after the described growth root of grafting, 1 year will be outside veteran tree crown projected area scope with interior organic fertilizer, later on normal fertilising in a year.The growth root that can prevent grafting is subjected to fertilizer damage.
The invention has the beneficial effects as follows: utilize the mode of grafting growth root on the lateral root of old peach to cultivate the peach that makes new advances, life cycle and the full bearing period of peach have greatly been prolonged, substitute in the old peach process in new peach simultaneously, the output of peach can not be subject to too large impact all the time, has greatly improved the benefit in peach garden.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail: the hypothesis peach is planted in the Northern Hemisphere in the present embodiment, peach life cycle prolongation method, may further comprise the steps: one, dig and open the earth in old peach southern side, under earth, find out the lateral root of old peach, with the rapid grafting of growth root about 1cm to the lateral root of old peach.It is fast that the speed of grafting is wanted, if the time has been grown, the bevel of grafting place can produce oxidation, the survival rate of impact growth root.Go up on the Northern Hemisphere, the side that faces south of peach is positioned at the south of peach, and day side sunlight is good, and well developed root system is grown fast, so the growth root survival rate of grafting is high and the ratio of growing up is very fast.The opportunity of grafting is also very important, and is general when the age of tree of old peach is 14 to 15 years, carries out grafting, peach one decreased year after year to the decline phase, and young sprout is more and more less and lack, and the peach brittleness is also more and more serious, accidentally, large branch is all for fractureing, and the above also hangs half cooked peach.And the age of tree of old peach carries out grafting too large the time again, and is may old peach dead, and newly peach does not also begin the result, will affect like this output of peach.
Two, when new peach length arrived 2-3, old peach was removed branch gradually, abdicates the space of little tree seedling growth, and little sapling grows up to new peach gradually.In the process that old peach is replaced by new peach gradually, pay special attention to look after new treelet, note again the old peach not underproduction reduction of income itself, accomplish progressively to remove year by year old peach branch, can not hinder little peach growth, provide enough auxiliary support branches for little peach again; Second Year, peach partly are received in old peach and partly are received in new peach; Can remove whole branches of old peach after the 3rd year.
Three, long when can satisfy tree root nutrition to new peach, the part of old peach except tree root removed.Concrete grammar is transported behind the old peach or is burnt for amputating, and the peach pile can not be exposed at above the soil, and the stub under the soil is carried out lime spray, and prevents that the winter of various insects from hiding and the termite intrusion.After old peach removed, new peach had been replaced old peach and has produced peach.
In the whole process, the root of old peach is being survived all the time, be equivalent to grow new tree crown in old peach, in the process, in the middle of the cultivation period of new peach, fruit is also being produced in the orchard always, and original trasplanting method, the nurturing period of the first two years does not have harvest, and the income that this has just increased the orchard greatly has 45000 mu of peach gardens such as honey peach base, Fenghua, for avoid ground per 20 years one change the garden after, the front 2 years cultivating and managing phase does not have income, and adopts become the full bearing period 2 years management phases of advanced method of our science, can increase income (45000 mu * every mu 4000 yuan * 2 years)=360,000,000 yuan.
