Description
Technical field
The invention belongs to agriculture field, and in particular to a kind of quick method of living again for Prospect on Kiwifruit Bacterial Canker tree.
Background technology
Kiwi berry is emerging fruit in the world, is the important industry of the provinces such as China's western region Sichuan, Shaanxi.In recent years
Global spread Prospect on Kiwifruit Bacterial Canker, it is a mortality strike to industry development.Prospect on Kiwifruit Bacterial Canker is that one kind is mainly shown as
Kiwi fruit plant trunk is festered, and epidermis flowing water is suppurated, and branch dries up, and individual plant death is presented when serious, and more plants of death are dead in flakes
Die, the situation of full garden Large Scale Death.
People are all based on the understanding of bacterial disease to the understanding of Prospect on Kiwifruit Bacterial Canker.Relevant Kiwi berry ulcer both at home and abroad
The pertinent literature of disease is essentially all so to describe：Prospect on Kiwifruit Bacterial Canker is a kind of destructiveness of serious threat Kiwi berry production
Bacterial disease；Canker is broken with tremendous force after occurring, and harm is huge, and heavy losses are caused to production, and the lighter's branch dries up the underproduction,
Severe one is extremely set, notably ruins garden.
Three during the last ten years, and international, domestic experts and scholars are to cause the vision of canker according to bacillary inducement to carry out
Study and prevent and treat, result is to make slow progress, and the scale of canker is increasing, and various prophylactico-therapeutic measures are substantially invalid.It is so far
Only, existing Prospect on Kiwifruit Bacterial Canker Prevention Technique is still referred to as global problem, or even some people is referred to as to be Kiwi berry
Cancer, it is believed that once there occurs canker for kiwi fruit tree garden, it is necessary to chop at a tree, the sterilization of Wa Shuquan gardens, or even strange land building well is no
Then, the garden will be destroyed overnight because of the uncontrollable of canker sooner or later.
It is widely recognized that Prospect on Kiwifruit Bacterial Canker is to cause kiwi fruit plant to become feeble and die, cause the disease of the regional significantly underproduction.
The disease is in 1980 first in California, USA and shizuoka County, Japan discovery, the Dong Shanfeng in China Hunan in 1986
Farm finds this disease, onset area 13.3hm2, cause kiwi fruit plant dead in flakes, it is later year after year popular.1989, Sichuan Province
Prospect on Kiwifruit Bacterial Canker is found in the Xi Kou forest farms of Cangxi County three first, is lost extremely serious.Shaanxi Xi'an region is since 1991 in length
Since peace Taiyi palace finds the disease first, its occurring area expands year by year, endangers getting worse, spread to week to, Hu County,
The Kiwi berry such as Ba bridges main producing region.The sick incidence of disease is high, has explosive, destructive feature, in addition existing existing method preventing and treating
It is ineffective, caused by economic loss it is huge.
Prospect on Kiwifruit Bacterial Canker is the destructive disease in Kiwi berry production, has been listed in Forest Plant Quarantine object,
Spread in recent years quickly, occurring area expands year by year, generates huge blow to western Kiwi berry industry.Using Sichuan as
Example, Sichuan is one of national Kiwi berry main producing region, the existing nearly 40000hm of cultivated area2, with the continuous increase of cultivated area,
In cities such as Guangyuan, Chengdu, Deyang, Yaans, there occurs Prospect on Kiwifruit Bacterial Canker, onset area and the state of an illness are in rising trend.Through first
Step is looked into, and the city of main product, county (area) morbidity orchard diseased plant rate 10~20%, serious reaches 30%~40%, and 2017
The morbidity more conventional time in year is even more serious, and part county, city, area cause 1 000hm2The loss of left and right, serious morbidity orchard
Diseased plant rate reaches more than 50%, or even the sound development ruined garden phenomenon, seriously hinder Kiwi berry industry in flakes occurs.
Canker Control Technology fails acquirement important breakthrough and is primarily present problems with：
1. think that canker is difficult to prevent and treat：Before this, most Kiwi berry researchers, training materials author and macaque
Peach grower, it is such description Prospect on Kiwifruit Bacterial Canker：Prospect on Kiwifruit Bacterial Canker is a kind of destructive bacterial disease, serious prestige
Kiwi berry production is coerced, once infection, the same there occurs cancer as people, can not be saved.We are thinking：An if large area hair
Raw canker can not be saved, then our 20~30 years new industries to grow up, will just face the wind of significantly atrophy
Danger.
2. prevention and controls are general, uncertain, effect is not notable:It is a variety of due to thinking to cause Prospect on Kiwifruit Bacterial Canker
Various, general Crack cause of concluding all is more than ten kinds, and corresponding prevention and controls just have many, it is necessary to which we are from these sides
Face one by one go correspondingly, go to implement, go to avoid, in fact, not accomplishing substantially.The Kiwi berry ulcer of wherein current main flow
Sick study on prevention is to have isolated bacterium on morbidity tree, advocates to be prevented and treated to sterilize fungi-proofing method before this, practical application
Poor effect, the method for then proposing integrated control again, because prophylactico-therapeutic measures is general, and has very big uncertainty, this
Sample has aggravated the production cost of grower, and canker still aggravates year by year.There is one to think Chinese series in integrated control
Kiwi berry is easier that canker occurs, and countermeasure is exactly to change kind, but operationally still has very big problem.
The pathogenic pathogenesis of canker is remained in numerous queries：Existing " is destructive on Prospect on Kiwifruit Bacterial Canker
Caused by bacterial disease " conclusion, be that everybody is universally recognized.But Mi is had found to the garden observation of several years of falling ill by us
Monkey peach canker has following bacterial disease occurrence regularity that is unusual, being described with existing research common people to have difference
Phenomenon, it is also necessary to further further investigation could explain：
1. at a Kiwi berry garden, one plant of morbidity, adjacent one plant of health are frequently found.
It is largely that the strong plant of 3~5 years ulcer occurs 2. canker generation is not related with Kiwi berry tree vigo(u)r power
Disease is even more serious on the contrary.
3. canker is commonplace in garden Diffusion Law, the phenomenon so independently occurred in individual plant, more plants, colony.With
Bacterium with the wind, water circulation way it is less consistent.
The content of the invention
The technical problems to be solved by the invention are：How effective the timely of solution Prospect on Kiwifruit Bacterial Canker tree is rescued
Control, get well.
The technical scheme is that：A kind of quick method of living again for Prospect on Kiwifruit Bacterial Canker tree, step are as follows：
(a) determine that the diseased plant of canker occurs for actinidia tree, to diseased plant focal part amputation；
(b) marrow, xylem and section to amputation section part sterilized, antiseepage, wrapping processing, prevent macaque completely
Peach body body fluid outflows；
(c) comprehensive desinsection, sterilization are carried out to plant；
(d) diseased plant is supplemented the nutrients；
(e) retain the new branch of trunk base portion, grafting is carried out in summer then or winter, planted after grafting according to normal
Training management.
Further, step (a) specific method is：It was found that tree trunk focal part flowing water at or rotten position or worm channel
Place, with the sawed-off trunk focus above section of saw, retain the good part of trunk.
Further, step (b) specific method is：Using sterilization anti-corrosion label insertion section marrow it is hollow in, block marrow
Portion, section xylem hollow position is coated using disinfecting enclosed agent, wrapping saw kerf section is closed using film.
Further, step (c) specific method is：Need using existing fumigation action have again it is contact efficacy, also simultaneous
Has the killing pests and suppressing bacteria agent of bactericidal action, it is necessary to effective to bark beetle.
Further, step (d) specific method is：Supplemented according to the composition of nutrition leak, nitrogen and phosphorus fertilizer potash fertilizer will
It is complete, trace element is also added, is supplemented using punching fertilising, quick-acting fertilizer, is important to add potash fertilizer.
Further, the specific method of step (e) is：Retain the new branch bar of three base portions, 1-2 are transferred for summer
Connect, 1-2 are used for winter grafting then, and first time grafting is June, the can grafting in May grown, second of grafting
It is November in winter then.
Achievement of the present invention is inventor by deep tune of the time more than 8 years in the main generating region of Sichuan Actinidia canker
Look into, find, study what is formed.It is to go to observe, recognize, study, preventing and treating using a kind of brand-new visual angle, brand-new path, completely new approach
Prospect on Kiwifruit Bacterial Canker.The key pathogenetic factor for causing Prospect on Kiwifruit Bacterial Canker is found first --- a kind of special worm " bark beetle "
Harm, gropes its pathogenic law, so as to study, sum up the technology of effectively preventing canker and method.For Kiwi berry ulcer
Crack cause, generation classification, controlling way, the prevention and controls of disease provide New Century Planned Textbook, a new technology.
Achievement of the present invention has big research and practice significance.In terms of research, it, which has to destroy the old and establish the new two, acts on, and breaks
It is old, refer to conceptually, change the understanding that people's past is exactly the bacterial disease of pure to Prospect on Kiwifruit Bacterial Canker；It is vertical new,
Seek to set up Prospect on Kiwifruit Bacterial Canker preventing and treating need insect pest, injury, fungus damage plan as a whole it is simultaneous control, the new ideas of integrated control.In reality
Aspect is trampled, it starts with from the mindset for breaking through conventional bacteria canker " disease ", changes preventing and treating path, innovative technology side
Method, the new situation that Prospect on Kiwifruit Bacterial Canker garden fast speed is come back to life is opened, reached unexpected good recovery disease tree
Effect, continue for Kiwi berry industry, developing in a healthy way provides new chance.
The principle of technical solution of the present invention is as follows：
One of principle：Abandoning that wound stays can Bao Shu：A large amount of investigation prove that the propagation of Prospect on Kiwifruit Bacterial Canker is not existing skill
Propagating with the wind, with rainwater described in art, be not Kiwi berry whole body all in spite of illness, a single but trunk or disease occurs, might not
Disease occurs for all trunks or branch, and disease occurs for this plant, is not that disease necessarily occurs for adjacent another strain.If bark beetle
Or it is artificial do not go to endanger another strain, another strain would not fall ill, growth of keeping fit.This be a universal phenomenon and
Rule, according to this rule, if we block trunk in spite of illness, or local branch, and need not block it is all it is non-in spite of illness
(good) trunk, branch, actinidia tree will not die, and good trunk can keep normally blooming, bear fruit, or continued growth is new
Branch come out.
The two of principle：It was found that and prevent flowing water channel can Bao Shu：Most canker plant are dead, be not because
For, it is dead in spite of illness, but because Kiwi berry body fluid (just as blood of people) passes through certain channel, it is lost in and dead, because
This, another measure, as long as preventing flowing water channel, effectively prevents from continuing flowing water (because the stream that this is exactly Kiwi berry hinders the phase), protects
The good trunk (part) of no flowing water is stayed, tree body just can as early as possible get well and send out branch again.
How to prevent to continue flowing waterBark beetle is trunk borer, and moth bores on actinidia tree, mouthpart touches to tree table skin
Wound, punching moth bore and form one by one small but also deep worm channel not only, are exactly the main channel of Kiwi berry flowing water fluid liquid, and then flow
Hinder phase endlessly flowing water, it is last because actinidia tree body fluid is all lost in, it is the main reason for actinidia tree is slowly die.
Therefore, as long as finding the channel of flowing water in time, place, the place festered for particularly having worm channel, removed using whole, reservation
The good trunk of part, may proceed to grow new, good branch and comes out.
The three of principle：Fracture closing can promote Kiwi berry shoot is newly dry quickly to live again：Mainly (metaphor is people for trunk amputation
Remove bad four limbs, the part avoided continues to degenerate) after will have substantial amounts of bleeding (equivalent to bleeding for people), by incision position
All closings.Past way is only to chop at a tree not close, and Kiwi berry flowing water is dead.Fracture sealing technique is that Kiwi berry is quickly lived again
Basis.And the key point of this technology.
The four of principle：Killing pests and suppressing bacteria can prevent ulcer from spreading:Bark beetle drilling can produce wound and also produce flowing water channel, and
And can also disease carrying germ, worm-wound-bacterium collective effect, Prospect on Kiwifruit Bacterial Canker acceleration sprawling, therefore, killing pests and suppressing bacteria, can effectively prevent
The only sprawling of Prospect on Kiwifruit Bacterial Canker.Past way is only antibacterial not desinsection, does not catch the key of injury --- worm in spite of wound, band
Stream, disease carrying germ.Therefore, this is that prior art effect is undesirable, arduous but fruitless fundamental cause.
The five of principle：Supplement the nutrients in time, quick-recovery tree body can be accelerated.There occurs the disease tree of canker, just as life
One serious disease is the same, it is necessary to timely supplements the nutrients, recovers tree body health as early as possible.According to Analysis of Nutritive Composition is lost in, by applying
Fertile supplement full nutritive element in time, tree body can be recovered than faster.
Compared with prior art, the invention has the advantages that：
The present invention does not go further, and prior art-digging tree ruins tree, clear garden sterilizes, changes kind of a replanting, (technology) old road blindly gone and buy Chinese medicine
Son.But by fluid stopping, control a new Technology Ways such as worm, allow Prospect on Kiwifruit Bacterial Canker tree do not dig completely tree in the case of have
Effect protection root system, the body fluid of nurse tree, the trunk that protects, send forth branches, quickly get well, radiate the vigour of youth again as early as possible,
Realization is ingeniously brought the dying back to life, and recovers production time 1-2 in advance, and avoid going further garden of ruining and the old road of strange land building well again.
Embodiment
Embodiment 1
1. determine object：Determination has occurred and that the garden of canker first, determines canker diseased plant, clearly requires amputation skill
The diseased plant of art.
2. select the appropriate amputation site of trunk：It was found that at flowing water or at rotten position or worm channel, above is needing
The trunk removed, it is the trunk for needing to retain below.
3. using certain instrument, carry out trunk amputation：General to use saw, saw is fast, and section is smooth.
4. tree cross section center marrow fluid stopping sterilization closing：This is a key technology, because actinidia tree is that liana is planted
Thing, marrow is hollow, and osmotic pressure is very big, once cutting, body fluid constantly flows outwardly, it is necessary to takes measures to block marrow.Method
It is empty with the anti-corrosion label of a kind of sterilization (bamboo stick or wood label be raw material) long 5-10cm, diameter 0.3-1.0cm, insertion marrow
In heart pipe, its size depth with can not allow marrow liquid outflow for standard.
Some hollow position fluid stopping sterilization closings of amputation cross section 5. (section) xylem：Solid powder is coordinated using sterilised liq
Last sealer, some hollow positions of above xylem are carried out with closing sterilization fluid stopping.Operating rate is fast, and effect will get well.
6. amputation cross section sealing wrapping：Using good, the stick-to-itive plastic sheeting of elasticity, double seal wrapping.Binder
Firmly packed with special binder, it is impossible to which it is standard to allow current (infiltration) to come out, and this is successful key.Successful feature
It is that cross section to be seen sticks out a bubble, osmotic pressure is very big, illustrates that cross section sealing is wrapped up successfully.
It is 7. whole plant desinsections, antibacterial：To actinidia tree trunk, branch, a desinsection, sterilization are carried out, will to tree trunk
Emphasis desinsection (bark beetle), to use existing fumigation action have again contact efficacy, also have the killing pests and suppressing bacteria of bactericidal action concurrently
Agent.
8. supplement the nutrients：There occurs the actinidia tree of canker, whole tree body is very weak, nutrition leak, according to nutrition
The composition of loss is supplemented, and nitrogen and phosphorus fertilizer potash fertilizer is complete, also to add trace element, is applied fertilizer using punching, and quick-acting fertilizer is carried out
Supplement.It is important to add potash fertilizer.
9. science retains tender shoots, spray：Typically retain three new branch bars, 1-2 are used for summer grafting, and 1-2 is individual
For winter grafting then.
10. grafting early：First time grafting is June, the can grafting in May grown.Second of grafting is to work as
Or so November in winter year.
11. normal management：The seedling normal management newly grown later, full garden, which is done step-by-step, to resume production.
Above-mentioned measure is taken, can realize that actinidia tree is quickly lived again as early as possible.Technology is simultaneously uncomplicated, and cost is not high.Live again
Rate more than 95%, quick (one week or so) rate of living again more than 85%.
Carry out bark beetle and the investigation of " canker " relation in Sichuan
1. establish Canker-Resistance proving ground：Before 2009, we have found through substantial amounts of investigation, Prospect on Kiwifruit Bacterial Canker
It is not all individual plants that Integral synchronous damages kiwi fruit tree garden, often one plant is fallen ill, or a morbidity, and other adjacent
Individual plant or adjacent growth are completely normal.Therefore, we have proposed by new cultivation mode come the big of Canker-Resistance
Courage is contemplated, and establish in Sichuan Province Pengzhou City Tong Ji Zhen Huang villages in March, 2009 scientific base devise it is corresponding test into
Row research.(note：The base is the Department of Science and Technology, the support of Science and Technology Department of Sichuan Province, established by Sichuan Natural Resources Research Institute
" 512 " Wenchuan earthquake post-disaster reconstruction science and technology experiment and demonstration base).
2. follow the trail of canker：2011, we were found that 1 plant of Kiwi berry in the base there occurs canker first, 2012
Find that canker occurs for more than 10 plants of Kiwi berry year, it is 2013~2016, annual to increase 30~70 plants of generation canker plant newly,
The end of the year 2016 in March, 2017, adding up more than 400 plants of Kiwi berry, there occurs canker, incidence rate 14%.
3. find and prevent and treat bark beetle：In March, 2012, it is found that on the canker plant trunk of more than 10 plants of the base small
Worm channel, and canker occurs flowed clear water, yellow liquid quite a few is all flowed out from aperture.Serious diseased plant has 10~
20 holes, more even 30 worm channels, this kind of plant branch, leaf wilt are withered quickly, and trunk aerial part is 2~3
It is progressively withered after individual month.We tentatively sentence survey：The garden canker may have direct relation with small insect.
2014~2016, it has been found that more new small worm channels, it was further observed that more worm Characteristics of Damage.Very
To for a smaller actinidia tree, in the case where not seeing and having other any problems, as long as there is a worm channel flowing water,
This one tree is withered soon.
2016~2017 years, we were by observing small worm, collection small worm and field Position Research, and simultaneously reference has for indoor discriminating
Close documents and materials comparative analysis, finally identify this it is a kind of endanger Kiwi berry trunk insect be：Coleoptera, Culculionidae, bark beetle
Subfamily, strong material bark beetle.It is same category with the New harmful insect for endangering Kiwi berry found within the border in Guizhou Province such as Li You, refined.
4. carry out Black Bar Beetle controlling experiment with being investigated work on face
2013,2014 we respectively Guangyuan City Zhao Hua areas, Yibin City Xingwen County Prospect on Kiwifruit Bacterial Canker occur garden
In area, it is found that study base morphological feature identical small worm channel in canker tree (trunk) You Yuhuang villages is present.
2016~2017 years, the seriousness with Sichuan Actinidia main producing region canker was progressively aggravated, and we organize
The special surveys of the ground on Black Bar Beetle Kiwi berry such as Cangxi County, Zhao Huaqu, Dujiangyan City, Pengzhou City, Lushan County.Knot
Fruit, the situation of Black Bar Beetle Kiwi berry is found that in the serious area of Prospect on Kiwifruit Bacterial Canker.
By the investigation in big region, with reference to us in the past few years to Prospect on Kiwifruit Bacterial Canker different disposal measure to having a competition
Test, we tentatively propose a kind of new hypothesis that worm inducement occurs on Prospect on Kiwifruit Bacterial Canker：Black Bar Beetle and Kiwi berry ulcer
It is sick directly relevant.It accelerates bleeding by destructive brill moth trunk, causes Kiwi berry garden deadwood in blocks, dried-up, dead tree.
Certain areas be probably cause Prospect on Kiwifruit Bacterial Canker occur in addition destroy orchard the main reason for one of.The hypothesis enters one by us
The experiment of step and face up-regulation are looked into and are confirmed.
During the process of the investigation, Sichuan Province Zhao Huaqu, Cangxi County have found that before Kiwi berry planting household it is this unknown small
Worm endangers the phenomenon of Kiwi berry.The harm of bark beetle large-scale outbreak causes the plant large area such as elm, pine tree, grape dried-up, withered
There are document report, hazard symptoms and the aggrieved pole of Kiwi berry in branch, dead leaf, situation about even extremely setting, domestic other areas and Sichuan
Its is similar.
Observation and Primary Study are investigated by us within nearly 5 years, it is believed that wound-worm-bacterium collective effect is Prospect on Kiwifruit Bacterial Canker hair
The elementary path of hair tonic exhibition, wherein, Black Bar Beetle be probably Kiwi berry large area is dried-up, deadwood main causes of death it
One.It is analyzed as follows：
1. in same Kiwi berry park, one plant of even climing morbidity, adjacent one plant or one it is dry on it is another
Climing the reason for not falling ill, it may be possible to one plant or a climing Black Bar Beetle and fall ill, adjacent one plant or a climing bark beetle do not have
Go to endanger and act normally.
2. canker occurs not related with Kiwi berry tree vigo(u)r power, this is probably due to either big little tree, either
Strong age tree or aging tree, as long as there is Black Bar Beetle, it may all occur.
3. our investigation is found, it is (3~5 years) strong tree that canker tree is most of, is well developed root system, bears fruit
More trees, this is the universal phenomenon that we have found in the investigation of multiple producing regions.Its reason we primary explanation be, it is strong tree moisture with
Nutriment enriches, and can more attract bark beetle to attack；On the other hand, strong tree Bleeding Intensity is big, once in the bleeding phase by small
Moth attack (punching moth dry), flowing water suppurate morbidity possibility it is larger.
4. canker is to surround a central point or multiple central points, develop to the radial diffusion of surrounding, therefore have
Individual plant morbidity, microcommunity morbidity, the feature fallen ill in flakes.It is probably because when bark beetle population size very little, endangering individual plant；
When bark beetle Population is smaller, the morbidity of microcommunity Kiwi berry is endangered；When bark beetle reproductive population quantity is bigger, danger
The a piece of Kiwi berry of evil；When bark beetle quantity is enough, Prospect on Kiwifruit Bacterial Canker occurs as soon as burst, large area, crushing generation
Situation.
Bark beetle causes Prospect on Kiwifruit Bacterial Canker to continue the possibility Analysis on Mechanism that scale occurs
1. the mechanism persistently occurred：By Primary Study, it is believed that：Caused by leading Prospect on Kiwifruit Bacterial Canker of bark beetle
Anttdisease Mechanism is probably：Based on insect bite+bleeding, the tree body body fluid (especially in the bleeding phase) of aggrieved Kiwi berry is caused constantly to be lost in,
Deadwood is dried-up unavoidable；Substantial amounts of brill moth, stab, gallery, resin all unavoidably infects various germs, and enter resin or
Circulating propagation in person's tree body, worm-wound-bacterium collective effect, the body fluid on the one hand set constantly are being reduced, and another aspect fungus damage is continuous
Increase, the two accelerates Kiwi berry and causes injury, causes a disease, decays within a short period of time.
2. the mechanism that scale occurs：In the Kiwifruit Culture garden of a scale, using bark beetle as leading worm-
Wound-fungus damage for a long time, under extensive, profound collective effect, Kiwi berry individual plant, more plants, in groups, in flakes by worm-wound-fungus damage
Harm, the extensive property in the region occurs, even generation canker can hardly be avoided year after year.
3. internal cause：1. bark beetle lateral road brill moth trunk branch flowing water injures.2. bacterium endangers.3. sustainable brill moth trunk danger
Evil.
4. external cause：1. Kiwi berry trunk, branch marrow are hollow, moisture enriches, and epidermis is very thin, and bast is loose, xylem
It is porous, it is easy to which that, by brill moth and flowing water, easy injury simultaneously infects fungus damage.2. bleeding accelerates resin excessive and bacteria infection.
Embodiment described above only expresses the embodiment of the application, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the application protection domain can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, on the premise of technical scheme design is not departed from, various modifications and improvements can be made, these belong to this
The protection domain of application.
