Description
Technical field
The present invention relates to the plant protection field, more specifically, the present invention relates to a kind of complex treatment technology of banyan root rot.
Background technology
Banyan root rot, the root that refers to the woody arbor of Ficus (Ficus spp.) receive to be harmful to the decay that causes after little Phellinus (Phellinidium noxium) infects.This sick common kind of easy infection has Ficus microcarpa (F.microcarpa), banyan (F.benjamina), India's gum (F.elastica), Ficus hispida (F.hispida), bodhi tree (F.religiosa), Huang Geshu (F.virens) etc. in the woody arbor of Ficus.The poisonous layer pore fungi has another name called harmful shelf fungus, poisonous layer pore fungi, rubber wood timber shelf fungus, and the Latin different name has Fomes noxius, Phellinus noxius, Phellinus lamaensis.The fruit body of germ is bigger, wooden stockless, and calm warp, semicircle, the rust brown, the edge is blunt thick, and the unsmooth and densely covered aperture of lower surface is for producing the porous layer of basidiospore.Basidiospore oval or obovate, unit cell, colourless, wall thickness, size is 4-5 μ m * 3-4 μ m.The cardinal symptom of banyan root rot has: bizet, and young leaves and young sprout quantity obviously reduce, and young leaves is less than normal, and Lao Ye chlorosis, flavescence come off at last in a large number, and sprig is withered; Root, surface irregularity, through pathogen mycelium and silt adhesion, serious surface has covered with yellowish-brown mycelia film, mycelia film surface undulation porous such as felt shape.The xylem of old complaint often is white in color rotten, and brown band line is arranged, and can smell sour smelly mushroom taste.
This sick method of treatment mainly is with bactericide pouring old complaint and surrounding soil at present, but this method can only partly be killed soil and the outer field germ of root, and is limited to invading the inner germ effect of root, more can not save weak tree vigo(u)r.Simultaneously because the wound of banyan can lactation, with producing certain pressure, thus another kind of effectively prevention and elimination of disease and pests and extra-nutrition moisture technology---trunk injection is not suitable for banyan, this point obtains proving through our experiment.
In order to ensure result of treatment; Take into account operability simultaneously; This complex treatment technology is thoroughly rooted out in root and the soil the pathogen measure except that comprising, has also worked out acrial part focus and the measure that recovers tree vigo(u)r rooted out according to propagation characteristic of pathogen and the biological property of banyan itself.As utilize the flourishing characteristics of banian aerial root, lose the root of dying of illness of function with the aerial root instead of part; Banyan cadre's branch is very flourishing, and side shoot is thick, and the first round branch short relatively, technology of being abutted against capable of using supplements the nutrients.
Present technique is applicable to the banyan ancient and well-known trees that treatment has been fallen ill, is not the healthy trees morbidity of prevention.
Summary of the invention
The objective of the invention is to overcome the defective of existing method treatment banyan root rot poor effect, provide a kind of result of treatment good, workable complex treatment technology.
To achieve these goals, the present invention has taked following technical scheme:
1, rooting out germ and sick portion handles
A) soil removal and replacement and sterilization.The radius of soil removal and replacement scope is confirmed according to size and the surrounding environment of disease plant, is generally 5-10m; The degree of depth is confirmed according to occurring degree, is generally 0.5-1m.Soil can be selected other local cleaning rich soil or preparation voluntarily for use, fills a prescription to be river sand, peat and each a mixing of nutrition soil.Before earthing, irrigate subsoil with the high concentration soil disinfectant.Soil disinfectant selects for use commercially available back to be illustrated as the bactericide of soil sterilization purposes, also can use carbendazim, tpn and thiophanate methyl to replace, and working concentration is higher than spraying concentration 20-50 doubly.Irrigate new soil behind the earthing again, watered once in after this every 1-3 month, until healing.
B) old complaint is handled.Cutting out the topsoil that carries disease germs, do not inserting as yet before the new soil, old complaint is being handled.All remove earlier, smear Wound protective agent at wound and above 30cm with cutting checkmate root and old complaint of big root and the method for cutting rootlet.As buy commercially available product, the effect on the packing instruction should comprise effects such as preventing pathogen infection, waterproof and promotion callus growth.Also can prepare voluntarily, filling a prescription is maltha and each a mixing of high concentration systemic fungicide.
C) cadre's cleaning.Often remove the dry branches and fallen leaves of trunk bifurcation accumulation, as the symptom of finding to rot sprays high concentration therapeutic type systemic fungicide immediately.Main cause is that disease fungus is except that soil-borne infection; Its basidiospore and mycelium also can spatter through wind rain and propagate on the trunk; And under the protection of litter, rest on the trunk bifurcation for a long time, make bifurcation ponding like high-temperature high humidity climate, just inoculum begins to infect activity.
2, short root and keeping
A) the short root of butt.Cover after the new soil, select the part butt to urge root and handle.In the face of land of butt makes progress the scope of 30cm, carve earlier and hinder epidermis, smear the mixed liquor of high concentration systemic fungicide and root-growing agent again to cambium with the pocket knife of having sterilized.Root-growing agent uses (available from ABT center, China forest-science academy, Beijing) GGR6 number, and concentration is 0.02-0.05g/L; Or use methyl and indolebutyric acid preparation, concentration is respectively 0.05-0.2g/L and 0.1-0.4g/L.Whenever be coated with once, grow until new root, and cover with soil at a distance from 3,4 days.
B) utilization of aerial root.The cluster aerial root that chosen position is concentrated is relatively packed in the pvc pipe; In pvc pipe, insert again new sandy soil (composition as 1, a); The depth of fill to the landfill gas above 10-20cm of growing point (confirming the length of pvc pipe highly in advance) of taking root according to this; The fixing PVC pipe; Every in pipe, watered the plant nutrition liquid that is added with root-growing agent and bactericide at a distance from 3-4 days, into 0.05-0.1g/L GGR6 number of filling a prescription, or methyl 0.05-0.1g/L adds carbendazim or thiophanate methyl wetting powder 2-10g/L, urea 0.3-0.8g/L and KH
2PO
40.1-0.5g/L.After a while, note observing the pvc pipe bottom and have or not aerial root to grow, goed deep into surface soil, then abolish pvc pipe, expose aerial root, and bury the front end of root with soil like aerial root.
C) be abutted against.The similar grafting of method of operating.Buy the little banyan of number strain according to the size of banyan tree and landform etc., the diameter of a cross-section of a tree trunk 1.3 meters above the ground of little banyan is slightly less than the banyan tree side shoot diameter that is abutted against operation.The part bark that the banyan tree side shoot need be abutted against the position prescinds, and exposes xylem, longitudinally the xylem of arch is evened out a little again, according to the bizet that little banyan is surgeried in the area inclination on its plane, exposes the trunk xylem of similar area.Under little banyan kind, the exposed xylem of two trees is coincide, notice that especially both cambium butt joints are neat, and tight wrapping, treat that it heals fully after, clip little banyan and be abutted against the above limb in position.
3, ancillary method
A) lopping.Like high temperature season, excessively rising for preventing, alternative is clipped part does not influence tree-like branch attractive in appearance, clips weak and dead branch simultaneously yet.Handle wound in case infect with Wound protective agent.Lopping ratio 30-50%.
B) clear up the tree that dies of illness on every side.Like near the trees (this cause of disease also can endanger a plurality of seeds such as rubber, acacia confusa, China tree, horsetail beefwood except that infecting Ficus) that same cause morbidity or death are arranged, need clear up to it, prevent that pathogen from diffusing to the scope of having handled once more.Root out earlier, press the method cleaning soil of 1a again.
C) bactericide regularly is coated with dried.Look the degree of being in a bad way, inhale the conductivity bactericide in using,, smeared disease butt (the above 30-50cm in ground) 1 time in every 7-10 days, prevent germ superinfection, until the rehabilitation of disease tree like 20-50 such as carbendazim times liquid.
Embodiment
Specify the present invention below in conjunction with a specific embodiment.Employed raw material comprises among the embodiment: 40% root-rot would rather moist dose (Dongguan City RuiDeFeng Biology Science Co., Ltd), 40% carbendazol wettable powder (Shanghai Shenglian Chemical Co., Ltd.), methyl (Shanghai uncle bio tech ltd difficult to understand; Analyze pure); Indolebutyric acid (Shanghai uncle bio tech ltd difficult to understand is analyzed pure), urea (1Guanghua Chemical Plant Co., Ltd., Guangdong; Analyze pure), KH

The host is a Ficus microcarpa, is positioned at Shantou City, Guangdong Province unit.The about 80cm of the plant diameter of a cross-section of a tree trunk 1.3 meters above the ground grows on the hillslope, and trunk tilts about 60 °.On inspection, with the susceptible basically necrosis of the root below the tangent horizontal line of butt, account for 2/3 of total root quantity, foundation above the horizon is originally normal, accounts for 1/3 of total root quantity.
1, rooting out germ and sick portion handles
A) soil removal and replacement and sterilization.Root is not above the horizon fallen ill, but contains the inoculum of pathogen in the soil yet, therefore needs soil removal and replacement yet.The radius of soil removal and replacement scope is 6m; The degree of depth is 0.5m above the horizon, following 0.8m.The cleaning rich soil that new soil ships for other place.Before earthing, rather irrigate subsoil with 100 times of root-rot.Irrigate new soil behind the earthing again, watered once in after this per 1 month.
B) old complaint is handled.Earlier the root of dying of illness below the horizontal line is all removed, smeared the protectant of carbendazim preparation of 1: 1 maltha and 50 times at wound and above 30cm.
C) cadre's cleaning.Check the trunk bifurcation week about, remove the dry branches and fallen leaves of accumulation,, strike off mycoderm and rotten cortex to healthy xylem immediately, smear the protectant of carbendazim preparation of 1: 1 maltha and 50 times if any the mycoderm growth.
2, short root and keeping
A) the short root of butt.Full tree carries out this kind processing of 10 places altogether, carves the mixed liquor of smearing 50 times of carbendazim and root-growing agent after hindering.Root-growing agent uses 0.1g/L methyl and the preparation of 0.2g/L indolebutyric acid.
B) utilization of aerial root.Used pvc pipe diameter 15cm packs aerial root as much as possible in the pvc pipe into, and 27 pipes different in size are set altogether, in pvc pipe, inserts new sandy soil again.The prescription of nutrient solution adds urea 0.8g/L and KH for methyl 0.1g/L
2PO
40.5g/L.
C) be abutted against.Selected 10 side shoots altogether, measured earlier side shoot diameter and the domatic height of distance, the data little banyan of having bought 10 diameter of a cross-section of a tree trunk 1.3 meters above the ground 10-15cm altogether is abutted against in view of the above.
3, ancillary method
A) the minority branch is dead, and growth has rot fungis such as bracket fungus and auricularia auriculajudae, and the worm channel of bark beetle is arranged, and has therefore clipped all dead branches, and handles wound with the wound film coating protective agent.Lopping ratio about 10%.
B) cleared up a little banyan apart from the about 9m of banyan tree.It is dead that this little banyan has infected identical disease.
Begin to take the measure except that being abutted against in late October then, in early Febuary, second, shake off soil at the bottom of the pvc pipe and observe aerial root, generally elongation surpasses 20cm, and the short root position of most of butt has gone out root.Though the treated mycoderm that still produces of minority butt is arranged, strikes off immediately and disinfect after finding.Early March begins to sprout sprouting.Late April is abutted against processing.Early June, most of aerial root landed, promptly abolished pvc pipe, aerial root is introduced in the soil grown.The whole existing obviously recovery of tree vigo(u)r this moment, but poorer slightly with normal phase than still, therefore remove about 20% weak branch (confirming) again according to the leaf growth situation on the branch.Observe in March, the 3rd, and new root-rot does not take place, and the place of being abutted against of banyan tree and little banyan is healing fully, sprouts a large amount of sproutings, and it is normal that tree vigo(u)r recovers basically.
More than be merely specific embodiment of the present invention, do not limit protection scope of the present invention with this; Any replacement and the improvement on the basis of not violating the present invention's design, done all belong to protection scope of the present invention.
