Description
Technical field
The invention belongs to agriculture field, the Semen Juglandiss land for growing field crops cold-resistant grafting seedlings-growing method of specially suitable cold plateau area.
Background technology
Qinghai Province be China in addition to Heilungkiang, Shanghai, Guangdong, Hainan, Taiwan, one of 26 Semen Juglandiss distribution provinces are subordinate to
, just there are the tradition and custom of plantation Semen Juglandiss in great Northwest producing region since ancient times on river the Huangshui River valley floor.Earlier 1990s, with
The development of national early reality thin skin Walnut Industry, our province also progressively start to plant early reality thin skin New Walnut Cultivars, and by Walnut Industry
Important composition as industry restructuring is listed in the planning of Qinghai Province Development of Forestry Industry respectively, using Walnut Industry as
One of five big forestry leading industrys emphasis is cultivated, and is proposed in the Yellow River, developed to the Huangshui River water paddy warp based on woody grain and oil Semen Juglandiss
The basic ideas in Ji woods base.But due to being affected by cold climate, Semen Juglandiss low seedling survival rate, winter survival rate are lower, cause
Semen Juglandiss land for growing field crops scale seedling raising is made to become a difficult problem, seedling base construction much lags behind industry development.Exactly lack one in production
Effective seedling raising mannerses are planted, during new varieties popularizing planting, Semen Juglandiss seedling all is from outsourcing, and due to kind introduction
The reasons such as channel is wide, introduces a collection differs, specialized nursery household lacks moral fiber, cause the Semen Juglandiss seedling quality of introduction uneven, grow directly from seeds
Seedling ratio up to more than 50%；Kind is mixed and disorderly, and breeding rate causes to introduce a fine variety for many years not result or result but quality and product less than 20%
Amount is low, economic benefit inhuman hope, restricts and affect the benign development of Walnut Industry to a certain extent.
The technical scheme of prior art one
The presently the most conventional prior art of walnut grafting nursery is square bud connection technology, and document report is more, and method is big
Same small difference, essentially identical.But extremely frigid zones are directed to, how on the basis of existing technology, by technique improvement, are carried out cold-resistant and is educated
Seedling, solves cold district land for growing field crops walnut grafting low seedling survival rate, and the more low problem relevant report of winter survival rate is rarely seen.
It is foundation with list of references 1 (LY/T 1,883 2010, Semen Juglandiss improved seeds Technical regulations for cultivation of tree seedlings), its square bud
The concrete technical scheme for connecing is：
(1) stock is cultivated
1. seed preparation, gathers kernel full, uniform in size, mildew and rot, fully ripe without disease pest, nothing from healthy and strong elite stand
Semen Juglandiss do seed, it is impossible to baking or bleach, it is impossible to use next year old kind of nursery.
2. seed is loaded gunnysack or is had in the volume basket of sealing, be totally immersed in flowing water river or pond, soaked by seed treatment
7d, pulls out after suctioning water, slightly dry in the sun, 80% stitching thread is sowed by ftractureing.
3. sow
A, sowing time
After soil thaws, mid-March is to late April for spring sowing.Planted in fall after seed collection, before soil is freeze-up
Carry out.
B, type of seeding, using trench digging program request, line-spacing 50-60cm, plant away from 15-20cm, ditch depth 8-10cm.The suture of nut
Line is perpendicular to the ground, plants point and points to parallel to the ground, thickness of earth covering 6-8cm, slightly suppresses after earthing.
C, application rate, application rate 75kg/666.7m2-100kg/666.7m2.
4. field management
A, middle weeding and it is completely cured, in trophophase is carried out, place of being completely cured is carried out to stock at the beginning of weeding 2-3 time, autumn late summer
Reason.
B, rich water quality management, during seedling growth, arid is poured water in time.June combines irrigates, and applies carbamide 10kg/
666.7m2-15kg/666.7m2；July chases after potassium dihydrogen phosphate 8kg/666.7m2-10kg/666.7m2.
C, the prevention and control of plant diseases, pest control, Major Diseases have bacterial black rot, anthrax, branch-rot, powdery mildew, root rot etc., can
800 times of liquid of 70% thiophanate methyl, 1000 times of liquid or 40% carbendazim are sprayed in period of disease.
Major Pests have Limacodidae, chafer, curtain to raise chi, spring chi, scale insect etc., can be with 3000-3500 times of bromine cyanogen
Chrysanthemum ester is prevented and treated.
(2) graft seedling growth
1. scion collection, fringe bar gather from cutting orchard or excellent elite stand, selects the peripheral robust growth of tree crown, without disease pest
Evil, give birth to semi-lignified developmental branch then, with adopting with connecing；As cutting orchard is distant, fringe bar cuts off compound leaf immediately after adopting, bottom is inserted
Transport under the conditions of entering cool place in bucket stand-by to nursery.
2. grafting time, then during tissue regeneration promoting tip semi-lignified, starts bud and connects.North China's late May is to mid-July
Bud connects.
3. grafting
A, bud is taken, buddered preferably the full bud in scion middle and upper part 35.Selected in fringe bar with double-edged knife crosscutting at bud
One knife makes the upper and lower sword of knife equal away from bud to xylem, then uses the single-side edge of double-edged knife respectively in one knife of both sides longitudinal cutting of bud,
The bud tablets of turning round lower band bud meat are gently broken, long 3 5cm, wide 1.5 2cm.
B, stock interface cut, and select ground diameter up to the stock of 1 2cm, choosing smooth place away from ground 30cm or so, take with
The stock skin graft of scion bud tablets formed objects, stock skin graft of then tearing make to leave a long 2-3cm at the stock interface lower right corner,
The dewatering outlet of wide 2-3mm.
C, anvil fringe are fitted together to, and the bud tablets for taking are embedded in rapidly the stock seam for cutting, and make upper and lower, left three directions
Closely it is affixed, then with plastic strip colligation from bottom to top, elastic appropriateness.Note buddering and expose, at the interface lower right corner outside dewatering outlet
Dew.
2.4 connect after manage, the rudiment that bud is erased on stock after connecing in time, scion wipe out, after surviving, above residue of buddering in time
Stock.Soil fertilizer and water management, middle weeding and the prevention and control of plant diseases, pest control are carried out in time.
The shortcoming of prior art one：
(1) list of references 1 for most of Semen Juglandiss growing area be applicable, but be short of in extremely frigid zones nursery more
Protection in winter is trembled with fear technical measures.Specially：
1. stock is cultivated and is not referred to cold-proof protective measure of surviving the winter.Extremely frigid zones, stock winter do not carry out cold-proof process,
Aerial partss will be caused seriously dry slightly even dead, affect next year to sprout, be seriously to may result in nursery to fail.
2. the cold-proof protective measure of surviving the winter of grafting one year seedling is not referred to.Extremely frigid zones, as temperature is low, trophophase is short,
After grafting, shoot length is limited, and degree of lignification is relatively low, and winter does not protect, it is difficult to survives the winter and causes nursery to fail.
(2) how after the stock next year green sprouting for not referring to cultivation in list of references 1 technical finesse is carried out.Because bud connects it is
High graft survival rate is carried out on the branch for giving birth to semi-lignified then, therefore spring stock should carry out stump, leave the strong bud one in position
Individual, remaining is erased.
(3) specify " grafting part is away from ground 30cm or so " in list of references 1, grafting part is too high.First, because water
Point, nutrient dredge and send distance remote, causing to budder in extremely frigid zones, sprouting is later, and increment is little, degree of lignification is low and be difficult to get over
Winter；Second, grafting part is too high, it is unfavorable for that winter survives the winter the enforcement of freeze prevention measure.
(4) for the determination of grafting time is excessively wide in range in list of references 1, it is " then during tissue regeneration promoting tip semi-lignified, to start
Bud connects ".And " the concrete bud in North China connect time be late May to mid-July " is specify only, and that extremely frigid zones bud connects is concrete
Time does not know.Test proves that extremely frigid zones, the time that bud connects are shorter, are mid or late June, crosses and can cause early or late
Graft survival rate is low or winter survival rate is low, and all that has been achieved is spoiled to make nursery.
(5) in managing after list of references 1 connects, " above remaining stock of buddering is wiped out in scion in time after surviving " technology is referred to,
Extremely frigid zones confirm through test of many times, do not apply to.Stock is not carried out cutting process after extremely frigid zones, grafting, and only existed
" wiping out above remaining stock of buddering after surviving in time ", can be excessive due to stock blade, and moisture and nutrient disperse, and cause to connect
Bud is not sprouted then or is not survived.After answering grafting, stock is wiped out on buddering at 3cm, compound leaf is not stayed, beneficial to immediate union of buddering
And sprout.
The technical scheme of prior art two：
Also refer to the square bud connection technology of Semen Juglandiss in list of references 2,3,4, but following some have area with list of references 1
Not, specially：
(1) process of stock
1. in list of references 2 to the treatment technology of stock before grafting for " before late March Semen Juglandiss rudiment, entering to seedling
Row stump, will seedling 10.0cm cuts off from the ground, and smear seal and shear oil in the face of cutting in time, to prevent moisture evaporation and disease
Bacterium infects.After early April Semen Juglandiss rudiment, 1 strong bud is stayed, remaining is erased without exception ".
2. in list of references 3 to the treatment technology of stock before grafting for " to height of seedling below 10cm 1 year raw seedling the
2 year spring not stump, will otherwise carry out stump ".
3. it is " before Semen Juglandiss seedling rudiment (early March) base portion to the treatment technology of stock before grafting in list of references 4
Retaining 5cm or so carries out stump process, in height of seedling 5cm, removes unnecessary rudiment, and during 20cm, pinching is increasing rugosity ".
(2) grafting time
1. list of references 2：In Shanxi Province Linfen Xiangfen County, " Semen Juglandiss square bud connects and typically enters in early June-late July
OK ".
2. list of references 3：" time that Huating region optimum square bud connects is June 10 to July 5, too early or too late
Bud take is all relatively low ".
3. list of references 4：" north is preferably in late May to early June " carries out bud and connects.
(3) grafting part
1. list of references 2：" apart from stock current-year branch 10.0～20.0cm of base portion, selecting 1 shiny surface " is carried out
Bud connects.
2. list of references 3：" selecting a shiny surface in base portion 10cm vicinity " carries out bud and connects.
3. list of references 4：" grafting part on stock preferably from the ground 5～10cm height ".
(4) connect rear stock to process
1. list of references 2：" more than interface, 5 compound leaves while grafting, are stayed to carry out cut anvil.After grafting, under such as running into
Rain, must carry out cut anvil, rainy 1 cut anvil 1 time, will finally leave at least 2 compound leaves.10.0cm or so is reached when buddering
When, compound leaf is all cut by cut anvil at the above 7.0cm of interface ".
2. list of references 3：" stock 15cm above sections are cut before grafting, 2～3 blades are only stayed on stock top, remaining
Blade is removed.When grafting is up to 15～20cm then can cut anvil, otherwise not cut anvil then treats that the 2nd year spring grew into 15cm
Cut anvil again when above.”
3. list of references 4：" after grafting immediately budder above stay 1～2 leaf cut anvil, to buddering, young sprout grows to 20cm or so
When, then from thorough cut anvil at the above 2cm that budders ".
(5) artificial rush is old
1. list of references 2：" in order to promote the abundant lignifying of grafting, strengthen winter cabbage, 40.0cm is reached when buddering
When, the appropriate phosphorus potash fertilizer that imposes, mid-August carry out pinching to sprouting, late August will control to water.For preventing innovation
Bar stripping and cold injury, when early October does not also fall leaves, will manually promote which aging, can spray Tianda-2116 medicinal liquid ".
2. list of references 4：" mid-August imposes compound fertilizer 10kg/667m2To improve nursery stock degree of lignification, can use
1.0 ‰ plant power-2003 carries out foliage-spray, not only can improve graft survival rate, while after can significantly improving grafting
Seedling height and rugosity ".
(6) survive the winter protection
1. list of references 2：" its branch can be whitewashed or be wound parcel from top to bottom with discarded thickness plastic sheeting by November,
Before freezing, freeze-up water is poured in time, make young sprout safe overwintering ".
2. list of references 3：" semi-finished product Seedling is taken and buries soil or the method protection against cold and freezing conditions with parchamyn paper packeted soil, and finished product Seedling is used
The method for burying soil or straw wrapping is antifreeze anti-air-dried.”
The shortcoming of prior art two：
(1) grafting time is excessively wide in range, is not suitable with High aititude cold district application
Relevant report about the Studies of Walnut Bud Grafting time is more, but carries out Semen Juglandiss for High aititude cold districts such as Part of Qinghai Plateau
The relevant report that bud connects is rarely seen.Carried in document 2,3,4 is the northern areas such as Shanxi, Gansu, and covering scope is larger, the north
Due to the diversity of weather conditions between each department, it is larger that bud connects time difference, not specifically.Impracticable.And the patent skill that applies
Art proposes the extremely frigid zones such as Part of Qinghai Plateau, and the suitable time of Studies of Walnut Bud Grafting is mid or late June, and bud connects time specific, concrete, practical
Property is higher.
(2) connect rear stock and cut that to stay long, compound leaf to retain more, moisture and nutrition disperse, unfavorable sprouting of buddering；And later stage bud picking
Workload is big, time-consuming take a lot of work, seedling cost is high
Vital work is played to the sprouting of the number for whether staying and retaining compound leaf to buddering of cutting of stock after grafting
With.Extremely frigid zones, temperature are relatively low, and crop growth period is short, cut anvil wood or do not cut that to stay excessive, compound leaf to retain excessive after connecing, because
Moisture and nutrition dispersion, the sprouting evening that can cause to budder, to grow thin and delicate, degree of lignification low or do not sprout then and be difficult to get over
Winter.Additionally, retaining compound leaf excessively, bud picking number of times can be increased, a large amount of labour costs are thus produced；Cut anvil often, is needed also exist for
A large amount of manpowers are completed, so as to increase seedling cost.And the patented technology that applies, for extremely frigid zones climatic characteristic, propose Semen Juglandiss
Bud wipes out stock after connecing at 3 5cm of top that budder, and rejects all compound leaves, can make to budder and heal more preferable, sprouting earlier, profit
In late growing stage and safe overwintering.Save labor, simple.
(3) sprayed as foliage fertilizer with the compound fertilizer or plant growth agent that promote growth, promote branch lignifying (old
Change), effect is not notable
Document 2,4 is mentioned, in Juglans Later growth, impose phosphorus potash fertilizer, compound fertilizer or spray Tianda-2116 medicinal liquid,
1.0 ‰ plant power-2003, can improve the degree of lignification of nursery stock.But indicated above belong to promote growth type fertilizer or
Foliage fertilizer, though play the role of promote nursery stock aging, effect has limitation.This technology patent is imitated using plant growth retardent alkene
Azoles promotes nursery stock aging, effect is significant.
(4) freeze prevention measure of surviving the winter is loaded down with trivial details, time-consuming take a lot of work laborious, effect inhuman hope
Carry out Studies of Walnut Bud Grafting in extremely frigid zones, overwinter management is a critically important link.Semi-finished product Seedling is not if got over
Cold then bud of protection in winter is easily freezed to death, and generating product Seedling then does not carry out surviving the winter cold-proof, and seedling stem is often because medulla is big, degree of lignification is poor
And be lyophilized, or even whole strain is freezed to death, and therefore must take freeze prevention measure." whitewashing its branch " that document 2 is mentioned is outstanding to treelet
Which is that the cold-proof of seedling has little effect, and trunk whitewashing is simply applied on big tree, with the effect that anti-disease pest, anti-day burn, its
Body has no direct antifreeze effect." winding parcel from top to bottom with discarded thick plastic sheeting ", time-consuming take a lot of work laborious, in actual production
In be difficult to carry out；Additionally, Part of Qinghai Plateau winter cold is very long, the cold-proof effect of plastic sheeting winding parcel is unsatisfactory, and the spring
Seedling bud is easily scalded during Ji Shengwen.
Mention in document 3 that " semi-finished product Seedling is taken and buries soil or the method protection against cold and freezing conditions with parchamyn paper packeted soil, and finished product Seedling is with burying
The method of soil or straw wrapping is antifreeze anti-air-dried ".In actual production, semi-finished product Seedling soil bury be feasible, but must remarks
Buried with dry ground, and can not be watered after soil is buried.Otherwise nursery stock can go rotten because soil water content is high.And use parchamyn paper packeted soil and
The method of straw wrapping, takes a lot of work in large-scale production laborious, and production cost is big, it more difficult to implement.
Content of the invention
The present invention is relatively low for cold plateau area temperature on average, temperature instability, and day and night temperature is big, and winter cold is very long
Climatic characteristic, technical backstopping is connected in existing Semen Juglandiss square bud, by grafting time, connect the process of rear stock, artificial promote
The improvement of measure and the reinforcement such as always, survive the winter cold-proof, the Semen Juglandiss cold-resistant of a kind of suitable extremely frigid zones application that researchs and proposes efficiently is transferred
Connect method for culturing seedlings, the method can solve that cold plateau area land for growing field crops walnut grafting survival rate is low, the difficult problem that winter survival rate is lower,
So that extremely frigid zones development scale Semen Juglandiss land for growing field crops bud connects nursery and is possibly realized, it is that extremely frigid zones set up Semen Juglandiss seedling breeding base

2.4 survive the winter cold-proof
Early October carries out winter irrigation, after topsoil is slightly dry, takes the ridging in narrow row of the soil in wide row, and by narrow row both sides
Seedling to bending on rib to inclination, then earthing 10cm is cold-proof.In spring in next year, according to weather condition, treat that temperature stablizes it
Earthing, and normal field management are removed afterwards.
The enforcement of freeze prevention measure in stock cultivating process, is buried by manually promoting old and soil of surviving the winter, and stock can be made to survive the winter preservation
Rate is significantly improved, and spring sprouts morning, is that the bud in later stage connects and striven for the favourable time
In technical solution of the present invention, for the stock that cultivates then, by artificial promote old and soil of surviving the winter bury cold-proof, can be obvious
Its wintering rate is improved, meanwhile, because freeze injury is not received in the protection of leaf bud winter, green sprouting morning, is that the time has been striven in young sprout growth, to 6
The length of month the middle ten days and the last ten days current-year branch, rugosity and half wooden degree reach bud and connect requirement.Test proves (table 1)：Give birth to then
Stock is promoted old and soil of surviving the winter and is buried cold-proof by artificial, and winter survival rate is 95.6%, and on April 25 or so started to sprout, then the summer
It is 82.3% that the nursery stock ratio that bud connects can be carried out season；39.2% is improve compared with control winter survival rate, spring bud flush is done sth. in advance
Nearly 10 days, can the ratio of grafting improve 33.8%, effect is obvious.
1 stock of table cultivates different technologies scheme winter survival rate and sprouting time contrast
Cold plateau area, carries out land for growing field crops bud in the suitable time and connects, and bud take and seedling growth amount can be made notable
Improve.
Specify in technical solution of the present invention, in extremely frigid zones such as Part of Qinghai Plateau, the Best Times that Semen Juglandiss bud connects are June
The middle ten days and the last ten days.Test shows (table 2)：Different time bud connects, and there is significant difference between graft survival rate, wherein with June 15 to July
Graft survival rate highest between 5 days, bud take reach more than 85%.Grafting too late after too early, survival rate are significantly reduced,
August just grafting, survival rate only have 10%；Hereafter grafting, is not survived substantially.Additionally, different time bud connects, its shoot length it
Between there is also different, and maximum with the increment of earliest grafting.
In production on the basis of survival rate is ensured first, to also ensure that nursery stock has certain increment then.Comprehensively examine
Consider every factor, cold plateau area Semen Juglandiss land for growing field crops bud is connected on that mid-June is most widely suited to carrying out between the last ten-days period, and bud connects around here,
Survival rate is high, up to more than 85%；Seedling growth amount is big, and new-tip length is close to 20cm, and rugosity, up to more than 0.8 cm, is that safety is got over
Winter lays the first stone.
2 different buds of table connect the time to graft survival rate and the impact of growth
In cold plateau area, after bud connects, stock is wiped out at the top 3-5cm that budders, and reject whole compound leaves, can be obvious
Sprouting time, and germination rate ahead of time (graft survival rate then) and seedling growth amount are significantly improved
After bud connects, different to the stock processing mode directly affects length and the germination rate of sprout time of buddering.Test table
Bright (table 3)：Stock Different treatments, its sprout time length of buddering are significantly different, and the impact to germination rate of buddering is aobvious
Write.Comparatively, after bud connects, the compound leaf stayed on stock is fewer, and the time of sprouting of buddering is more early, and germination rate is higher.Wherein with
After bud connects, at the top 3cm that budders cut anvil do not stay compound leaf process its budder sprout time earliest, germination rate highest, in grafting
About 59 days or so afterwards, germination rate (graft survival rate then) was i.e. up to 100%.And stock is left intact, budder and work as
Year does not sprout.
3 stock Different treatments of table connect the impact of sprout time and germination rate to bud
As can be seen from Table 4, stock different disposal is significant to the impact that young sprout grows.Comparatively, compound leaf is stayed
More, shoot length is less.After wherein being connect with bud, cut anvil does not stay the processing mode shoot length of compound leaf maximum, young sprout
Length reaches 0.87cm up to 24.15cm, rugosity.And stock is left intact, can not sprout because buddered then, so not having
There is increment.
Impact of the 4 stock different disposal of table to shoot length
After grafting survival, promote old and freeze prevention measure of surviving the winter using artificial, winter survival rate can be effectively improved
Cold plateau area, the height of walnut grafting Seedling winter survival rate is the deciding factor for concerning nursery success or failure.Logical
In the case of often, Part of Qinghai Plateau place winter cold is very long, does not take freeze prevention measure, seedling to be difficult to survive the winter；And freeze prevention measure is loaded down with trivial details,
It is difficult to carry out；Freeze prevention measure is simply not in place, and cold-proof effect is undesirable.Effective cold-proof technology is to ensure that nursery stock is got over safely
The key in winter.
Test shows that the seedling growth later stage sprays 400 times of 5% uniconazole P liquid 2 times in late August, is spaced 10 days, promotees which
Lignifying；And earthing is survived the winter after winter irrigation, winter survival rate is significantly improved.Test shows (table 5).
Impact of 5 different tests of the table process to winter survival rate
Later growth sprays uniconazole P 2 times, and the freeze prevention measure of winter earthing, winter survival rate are less sprayed up to 92.22%
Uniconazole P is applied, the process winter survival rate of winter earthing is high by 14.44%, high by 84.44% compared with compareing.Illustrate, winter earthing is survived the winter,
Winter survival rate can be significantly improved, effective.But spray uniconazole P 2 times at later stages, can further promote wooden formation,
So as to strengthen the cold-proof of surviving the winter of seedling.Two kinds of measure superpositions, can effectively improve seedling winter survival rate.
