Description

A kind of specular removal thin V-shaped cultural method of double strains for peach appropriateness dense planting
Technical field
The present invention relates to cultivation of fruit tree method, specifically a kind of specular removal thin V words of double strains for peach appropriateness dense planting Shape cultural method.
Background technology
Peach is the fruit in season of not shelf-stable, is one of people's predilection and nutritious large fruit, due to peach Miao Yu field planting after Second Year just can result, therefore cultivation when require Quick-forming to form yield as early as possible, this is just right Field planting pattern and individual plant shaping are put forward higher requirement.The traditional production of peach is tree-like mainly have two kinds, i.e. natural open centre shape and Trunk dredges layer and postpones happy shape, is not suitable for dense planting, therefore is unable to early origin yield.Plant as more advanced more seedlings wide row Training pattern, current popularity is simultaneously it is widely recognized that individual plant Y-shaped(Also referred to as fall " people " font or the happy shape of double major branches, 65 degree ~ 75 degree of angle between domestic major branch, abroad this angle reduce half, in order to mechanized operation, for the ease of this The contrast description of invention, is below referred to as tree-like " double major branches " " double trunks ")And trunk shape, with individual plant Y-shaped degree of recognition Highest, but it shapes relatively slow for going alone class and be tree-like, and branch assembles that to put position few, is only limitted to major branch both sides, branch group size Be limited to spacing in the rows and comparison is mechanical, two major branches and its affiliated branch group light efficiency influence each other, the lower light efficiency of the branch group back of the body is low, it is difficult to formed compared with For perfect spherical branch group, and large, medium and small type branch group mixture is difficult, the individual plant Y-shaped in mitre and ground angle between major branch It is little, soil is wasted, it is unfavorable for mechanized operation, if improving mechanization operability, it is necessary to reduce the angle between two major branches, but this Can cause influencing each other for light efficiency between two major branches correspondence branch group again, and the type of branch group must be adjusted with arrangement so as to change in quality Into another tree-like.At present, also someone among the people is promoting a kind of the tree-like of wide-angle tilt of both sides to the midline(Claim " two While falling "), close to 0.5 ~ 0.6 meter of spacing in the rows, with ground angle up to nearly 30 °, although its back can be needed with configuration result branch Twisting side, has actually tied up the configuration space of the branch group of trunk both sides.Therefore, except equally existing all of individual plant Y-shaped Outside defect, also exist because density is too high, other major defects such as ability of branch group sustainable renewal and sustainable result.It is special It is not too small with ground angle, does inevitable long, setting fruit position extension, is not only especially unsuitable for mechanized operation, and soil Utilization rate becomes lower.Additionally, also there are a kind of more seedlings wide space planting pattern of similar distribution in foreign countries, spacing in the rows can reach 1 meter, strange, Even strain also to capable both sides has inclined a less angle respectively, but it is specifically, is that one kind have rotated 90 degree and make two masters Branch is along row to the thin Y-shaped of the inclined individual plant in both sides(Herein we term it " individual plant rotates thin Y-shaped "), it is difficult between its pair of major branch Effectively to configure branch group, north and south row to field planting pattern under, the branch group exactly orientation at this position is best, light efficiency highest branch Group, it is seen that its defect becomes apparent from.Therefore, field planting pattern and appropriate tree-like and branch group structure reasonable in design is peach routine The crucial and difficult point of cultivation research.
The content of the invention
To solve above-mentioned technical problem, the invention provides a kind of double strains of specular removal for peach appropriateness dense planting are thin V-shaped cultural method, is colonized into little angle perspective V-shaped to keeping at a certain distance away, to reach using by more than 2 plants peach seedlings along row Convenient configuration branch group, the purpose for improving ventilation and penetrating light condition, forming yield as early as possible, can regard as individual plant Y-shaped in density A trunk along row to translation spacing in the rows half, expanded branch group distribution space, increased branch group species, shorten peach and reach To the time of economic flow rate, water, fertilizer, light, air and soil is set to obtain most fully and most reasonably using.
To reach above-mentioned purpose, the technical solution adopted in the present invention is:
A kind of specular removal thin V-shaped cultural method of double strains for peach appropriateness dense planting, is achieved by the steps of:

2)It is determined that row to seeding row spacing optimum range, to, spacing in the rows being 80cm ~ 120cm for north and south row, line-spacing is row 350cm~400cm;
3)With ditching machine along row to trench digging, its a width of 40cm ~ 50cm, depth is 40cm ~ 50cm, mellow soil is covered after fertilising, thereafter With lime mark field planting point, the point of field planting in the ranks is in the distribution of " well " font;
4) when being colonized the often odd number strain of row to row to the same side incline, make by straight lines of 2 field planting points in row and logical Cross trunk plane perpendicular to the ground vertical, even number strain inclined in opposite directions, inclination angle is 15 ~ 20 degree, fill permeable, in trunk 30cm ~ 40cm at, stay the full bud in a north side to cut off, insert 3 meters of long thin bars in trunk southern side, with trunk apart from 5cm ~ 10cm, incline Angle is consistent with trunk, and adjacent odd, even several plants constitute row to the thin V-shaped of double strains that perspective angle is 30 ~ 40 degree, and spacing in the rows is The half of individual plant Y words;
5)In addition to trunk north side is left near two full buds of top clip, other sproutings on trunk will smear in time Remove, stayed a vigorous branches to tie up along bar the shoot that the full bud of stayed trunk north side is sprouted in front and back in June 10 and help, another shoot exists Inserted part patch trunk is wiped out;
6)The Second Year of field planting wipes out on trunk away from below ground 60cm raw annual shoot, promote side shoot life portion The quick upper shifting in position, determines that the current year is cultivated newly again using trunk uniaxial extension or cutting back according to the length of tree vigo(u)r and blind section Head, no matter which kind of mode, the newborn extending head of trunk all should be tied up to be helped in thin bar, and the operation of the 3rd year new head is carried out successively;
7)To on trunk 1 year raw raw branch, select and remain by the direction of the four corners of the world 4, along trunk bearing of trend every 15 ~ 20cm stays 1, and the not good shoot in remaining close life or direction is wiped out from attachment region, and the raw branch in 1 for being stayed year gets rid of puts result, in August Bottom to early September cuts off shoot young tender part;
8)The branch group of three types, i.e., large-scale, medium-sized, small ball-shape branch group, west side or east side master are configured on trunk Under the dry back of the body, medium-sized branch group is matched somebody with somebody below the height of trunk 1/2, more than taper into and be transitioned into small branch group, south and north flanks are matched somebody with somebody The back of large-scale branch group, east side or west side trunk, with small branch group, continuous shaping is started from after field planting 3 ~ 4 years, when main it is long extremely After 3.5 meters high, handrail is tied up in removal, and light pruning removes apical growing point or gets rid of to a weak branch, the height of tree is kept at 3.5 meters or so, to Tied the annual shoot of fruit, cut in the winter then or early spring in next year prune when, according to large-scale, medium-sized, small ball-shape branch group technology will Ask, return and be reduced to the spherical branch group that suitable position cultivates year by year above-mentioned 3 type, adjacent odd strain or even number strain, its large-scale branch The extension of group is not to intersect as degree;The ductility of medium-sized branch group is the 1/2 ~ 3/5 of large-scale branch group;The ductility of small branch group is big The 1/3 ~ 1/2 of type branch group, is not prolonged with turning round branch and changing the branch group of nyctitropic mode culture different directions and change fruitful branch as far as possible Stretch direction.
Step 8)In, during shaping culture branch group, to nothing under trunk back or under branch group skeleton branch back The annual shoot of reserve value is directly removed, and then adopting for value of withing a hook at the end cuts to change the method generation of Secondary Branch bearing of trend For branch is turned round, the spherical branch group of large, medium and small three types is configured on trunk to improve light efficiency.
Field planting pattern provided by the present invention and tree-like easy to understand, it is easy to operate, be embodied in employing " well " font Field planting point is easy to layout, and shaping is easy, and tree-like attractive in appearance, garden is mutually neat, be easy to management, it is easy to accomplish mechanization, once and shape, Supporter can not be needed, so as to save investment, does not only have its brand-new tree-like and productive prospecting, and inheritance ground retains The plurality of advantages of other veteran shapes;The present invention can regard as a trunk of the individual plant Y-shaped that maximum spacing in the rows is 2 meters (Major branch) along going to being displaced at the 1/2 of spacing in the rows, become Plant colonization, to go alone the method culture of extension and ground in mitre Tree-like, the East, West, South, North all directions for making trunk can configure fruit-bearing shoot cluster, and south and north flanks still can configure large-scale ball Shape branch group, in such group raw its direction of extension of fruitful branch it is freer than the fruitful branch on individual plant Y-shaped, light efficiency is more It is high;Reduce because plantation density increased one times than individual plant Y-shaped to the macrotype spherical branch group arranged is no along row, on the contrary branch Group configuration space increased one times, and thing both sides have been respectively configured the spherical fruit-bearing shoot cluster of small-sized and medium-sized 2 type, Ke Yijin Amount takes less space in the ranks, not only improves raising light efficiency, and Economization on land is conducive to again, meanwhile, because of fruit-bearing shoot cluster type and The renewal leeway of the increase of quantity, branch group and fruitful branch is bigger, so as to substantially prolongs the Production Life of peach;Because staying branch amount It is larger, the bad annual shoot of the lower vertical growth of the back or the back of the body of trunk or branch group skeleton branch or light, if nothing further makes With value, should directly remove to replace turning round branch;With a hook at the end value, then change this bearing of trend for becoming Secondary Branch by cutting, So as to improve work efficiency, such branch set type will not change, and tree body is able to Quick-forming;The method that the present invention is provided is cultivated in peach During, water, fertilizer, light, air and soil can obtain most fully and most reasonably utilizing, and improve light efficiency, save soil Ground, the initil output of unit area is greatly improved, and is conducive to mechanized operation, considerably reduces human cost.

As preferred mode, step 8)In, during shaping culture branch group, under trunk back or branch group bone The annual shoot being worth without reserve under dry branch back is directly removed, and then the adopting to cut of value of withing a hook at the end is prolonged with changing Secondary Branch The method for stretching direction replaces turning round branch, and the spherical branch group of large, medium and small three types is configured on trunk to improve light efficiency.
Accompanying drawing is combined below by a specific embodiment to describe the present invention.
First have to level land, adjust the pH value of soil to proper range, determine line-spacing for 350cm ~ 400cm, trench digging width For 40cm ~ 50cm, depth is 40cm ~ 50cm, to apply and cover mellow soil 15cm after the thick barnyard manure of 20cm, is in lime mark field planting point thereafter " well " font.
As shown in Fig. 2 nursery stock is by the inclination angle field planting for determining, inclination angle is 15 ~ 20 degree, and north is stayed more than graft union after field planting One bud of side cuts off nursery stock, and head based on the shoot that the bud is sent out is cultivated as trunk.Clip and graft union away from From for 5 ~ 7cm, if autumn field planting, heap being painted and being earthed up on clip to more than graft union and be survived the winter moisturizing with profit, spring is near Mound is removed before germination.Autumn field planting is then pressed close to trunk and is inserted for 15 ~ 20 degree by inclination angle in mid or late June next year in nursery stock southern side Thin bar 3, starts to tie up main head and helps with tied rope 4 along the big knot that can be undone by a pull of leverage.Next plant of inclined in opposite directions, and identical is carried out according to this Operation;If spring is colonized, starts above-mentioned tying up in mid or late June then and help work.
As shown in figure 3, autumn field planting starts to determine branch after mid or late June next year;Spring is colonized then in mid or late June then Start to determine branch.Determining branch will immediately be carried out after insertion thin bar 3 is tied up and helped.Depending on individual plant growing way situation, height is wiped out below 40cm's Side shoot, with the lengthening of trunk, after 1 month, then wipes out the side shoot of below 60cm, and part more than this height is shaping strip, Upwards branch is stayed by 4 directions every 15 ~ 20cm rotations, or stay the shoot of a bud institute pumping to get rid of every 3 buds and put, such as Fig. 3 East side branch 5, north side branch 6, southern side branch 7, west side branch 8, east side branch 5 does not limit direction to be stayed the 1st, in practical operation, remaining Each branch presses successively different directions rotation separately distribution upwards.For what is wiped out side shoot is given birth to then and is not intended to stay cutting for branch The sprouting that oral area position or other similar positions are sent out will erase in time.
As shown in figure 4, the 2nd anniversary after field planting, at the end of winter and the beginning of spring or shaping strip bottom is accounted for entirely before spring rudiment in nearest The reservation side shoot of tree 1/3 carries out cutting back, and the medium-sized spherical branch group 10, southern side of culture such as east side small ball-shape branch group 9, west side is large-scale Spherical branch group 11 and the such classification branch group of north side macrotype spherical branch group 12, the guarantor after side shoot cutting back from cutting back mouth to inserted part The skeleton branch for staying part to be all kinds of branch groups, stays thereon 1 ~ 2 fruit or does not stay fruit, the length for retaining skeleton branch to be respectively:Large-scale branch Group and medium-sized branch group 20cm, small branch group 15cm;1/3 reservation side shoot in the middle part of shaping strip continues to get rid of puts result, and when staying fruit branch is regarded Power per stay 1 ~ 4 fruit, the 1st Winter-Spring culture branch group after result stays the length of skeleton branch than last time shortening 20%, whole Shape retains side shoot and selects extremely to weigh cutting back to 1 to 2 consistent bud row with culture branch prescription with top 1/3, and 1 conduct is stayed after germination Skeleton branch culture is simultaneously got rid of and puts result, is thought that the coming year continues to cultivate all kinds of branch groups and is got out skeleton branch.It is key to cultivate branch group 3rd time The retention length of branch is remained and shorten on the basis of last year 20%.Additionally, why spherical branch group 9 selects small branch group, a side Face is to make full use of space to improve outside light efficiency, on the other hand then having taken into account the convenience of plateau beta pruning, as shown in Figure 9.
As shown in Figure 5, Figure 6, shaping has been completed, with trunk 16 raw each skeleton branch 14 and the ball cultivated thereon The whole in place and clear in structure of shape fruit-bearing shoot cluster 15, obtain can make full use of space again can ventilation and penetrating light specular removal tree Body structure.
As shown in Figure 7, Figure 8, there are at 3 totally 6 directions in the space being wasted in the individual plant Y-shaped pattern of Fig. 7, and its odd number Land area shared by strain 17 be then equal in Fig. 8 double strain thin V-shaped odd number strains 20 and land area shared by even number strain 21 it With.The defect of Fig. 7 is mainly caused by western trunk 18 and owner dry 19 are radially superposed along east-west direction, the thin V-shaped of double strains of Fig. 8 Then overcome such defect.
As shown in figure 1, through 3 shapings in 3 years and pruning, after main long high to 3.5 meters, removal is tied up and helps thin bar 3, light pruning Apical growing point is removed, keeps the height of tree at 3.5 meters or so, the annual shoot to tying fruit is cut or early spring in next year in the winter then During pruning, according to large-scale, medium-sized, small ball-shape branch group technical requirements, return and be reduced to suitable position and cultivate above-mentioned 3 type year by year Spherical branch group.Not only tree-like attractive in appearance, garden is mutually neat for this tree-like and field planting pattern, it is easy to understands, and can make full use of Space, Economization on land, plantation density height can but improve light efficiency, reached and shaped the fast, purpose of instant effect.In addition, this whole Shape and building well pattern, can to greatest extent realize mechanized operation, and to save labor cost, being adapted to plateau machine carries out high-altitude The do mechanization operations such as the operations such as beta pruning, bagging, large-scale spraying machine and flower thinning machine.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck Change, remodeling, addition or replacement that the technical staff in domain is made in the essential scope of the present invention, should also belong to the present invention's Protection domain.
