Abstract

The invention provides the trimming method of a kind of peach, first rapid fixed dry after peach field planting, dry high 50-60cm, removes all branches on trunk while determining to do; Secondly twice pruning to peach seedling First Year, fast culture trunk, form the prevailing peach plant of central trunk, be aided with between three-dimensional fruiting area that corresponding fruit bearing shoot formed rapidly from 0.60 ~ 2.5m, to be condensed into " trunk+fruit bearing shoot " tree-like by tree-like, forms bearing capacity rapidly, 3rd from Second Year, pruned by the two-wheeled of bough fruit thinning branch that goes removing fruit bearing shoot and winter in annual summer, make tree-likely substantially to remain unchanged, keep the bearing capacity of single peach substantially constant.To be condensed into " trunk+fruit bearing shoot " tree-like by tree-like in the present invention, rapid formation bearing capacity, becomes three-dimensional result fruit branch layer simultaneously, wants space to vertical direction by plane result fruit branch layer tree-like for tradition, increase the growing space of fruit branch layer, improve painted and fruit food matter.

Description

The trimming method of a kind of peach

Technical field

The present invention relates to the pruning technique of fruit tree, specifically the trimming method of a kind of peach.

Background technology

The kind of peach is planted in pattern, promotion sets thin planting greatly mostly at present, planting density is 3*4m, 4*4m, 5*4m, even 6*5m etc. mostly, and three strand of six fork 12 is generally particular about in tree-like finishing, by drawing branch, pruning and substantially fruit bearing shoot is stablized in one plane, and be convenient to pluck, be convenient to again ventilate and receive sunlight, but due to the restriction of field plane space, cause fruit per mu yield limited, the peach garden per mu yield mostly entering high yield period only has 2000 to 3000 jin.

On trim mode, adopt the trim mode of "+fruit-bearing shoot cluster+fruit bearing shoot is done in trunk+production ", main employing is cut based on short, is easily forming fruit tree " trunk branch is many, fruit bearing shoot is few; setting fruit position is outer year by year to be moved " after pruning in a few years, cause the result of peach to present " village hollowing ", namely the periphery result of tree crown is many, and centre result is few, further reduction peach garden effectively take over area, cause output to reduce, show as the age of tree larger, output is lower.

Due to the apical dominance effect of plant, adopt cutting back pruning, be easy to stimulate the quick branch in branch clip rear end and growth, form " cutting back just moves faster outward " vicious circle; Meanwhile, no matter adopt which kind of planting density, the distance between spacing in the rows is limited, through pruning in a few years, tree crown will juxtaposition, forms overall closing gradually, loses bearing capacity, the premature termination lifetime of peach, lose economic benefit, finish the lifetime in peach garden in advance.Here it is, and many peach gardens have just entered the reason that high yield period just loses economic worth, cause peach garden to invest macroeconomic and are worth reduction, do not reach theoretical benefit.

Under existing plantation and Pruning model, through growth in a few years, the limb of peach has been covered with all spaces, peach garden substantially, and summer is both stuffy, is not easy to again work, easily grows disease, strengthens management cost.

Summary of the invention

The present invention solves the technical problem in the production management of current peach garden, simultaneously in order to obtain high-quality, high yield, the stable yields in peach garden, the special trimming method proposing a kind of high grade producing peach, production of fruit trees reaches two urge, " early stage promotes to nourish and grow, later stage promote reproductive growth ", a control " by later stage inter-row cultivation cut off floating root control nutrition altogether to, solve and nourish and grow ", results of use that two more " summer pruning upgrade fruit bearing shoot, intertillage be completely cured to upgrade and work as root system " is new.

For technical solution of the present invention is: the trimming method of a kind of peach, is characterized in that: first rapid fixed dry after peach field planting, dry high 50-60cm, removes all branches on trunk while determining to do;

Secondly twice pruning to peach seedling First Year, fast culture trunk, form the prevailing peach plant of central trunk, being aided with corresponding fruit bearing shoot is formed rapidly between the three-dimensional fruiting area of 0.60 ~ 2.5m, and to be condensed into " trunk+fruit bearing shoot " tree-like by tree-like, forms bearing capacity rapidly, tree-like plane result fruit branch layer is become three-dimensional result fruit branch layer simultaneously, to vertical direction growth, increase the growing space of fruit branch layer, improve painted and fruit food matter; Wherein summer pruning: namely carry out after peach harvesting terminates, the branch tying peach removes without exception, barren newborn branch then retains cultivates formation next year fruit bearing shoot, plant the beginning of July then and start pruning, its method is reservation trunk and weak raw branch, remaining competitive branch water sprout is all pruned off, retains peach height of tree crown at 2-2.5m, and hat width is at 1.5-2m; Winter pruning: remove large branch and unnecessary fruit branch, every strain peach retains 10-15 fruit bearing shoot, and trunk height keeps 2-2.5m, and too high trunk then changes head, intertills by the end of August;

3rd from Second Year, is pruned by the two-wheeled of bough fruit thinning branch that goes removing fruit bearing shoot and winter in annual summer, makes tree-likely substantially to remain unchanged, and keeps the bearing capacity of single peach substantially constant.

Beneficial effect:

It is tree-like that traditional " trunk+production dry+fruit-bearing shoot cluster+fruit bearing shoot " tree-like is condensed into " trunk+fruit bearing shoot " by the present invention, rapid formation bearing capacity, plane result fruit branch layer tree-like for tradition is become three-dimensional result fruit branch layer simultaneously, space is wanted to vertical direction, increase the growing space of fruit branch layer, improve painted and fruit food matter.

Embodiment

The present invention is first fixed dry rapidly after peach field planting, dry high 50-60cm(bud seedling exception), fixed dry while remove all branches on trunk;

Secondly by twice pruning to peach seedling First Year, fast culture trunk, form the prevailing peach plant of central trunk, being aided with corresponding fruit bearing shoot is formed rapidly between the three-dimensional fruiting area of 0.60 ~ 2.5m, traditional " trunk+production dry+fruit-bearing shoot cluster+fruit bearing shoot " tree-like is condensed into " trunk+fruit bearing shoot " tree-like, rapid formation bearing capacity, plane result fruit branch layer tree-like for tradition is become three-dimensional result fruit branch layer simultaneously, space is wanted to vertical direction, increase the growing space of fruit branch layer, improve painted and fruit food matter.

Summer pruning: generally namely carry out after peach harvesting terminates, the branch taking over peach removes without exception, barren newborn branch then retains cultivates formation next year fruit bearing shoot.The treelet of field planting then started pruning at the beginning of 7 months, and retain a trunk and weak raw branch during pruning, remaining competitive branch water sprout is all pruned off, retained peach height of tree crown at 2-2.5m, and hat width is at 1.5-2m.

Winter pruning: remove large branch and unnecessary fruit branch, every strain peach retains 10-15 fruit bearing shoot, and trunk height keeps 2-2.5m, and too high then changes head, intertills by the end of August.

Claims

1. a trimming method for peach, is characterized in that:

First rapid fixed dry after peach field planting, dry high 50-60cm, removes all branches on trunk while determining to do;
