Abstract
The invention discloses a method for enhancing the growth vigor of continued branches of pear skeleton branches obtained by trellis culture. The method comprises the following steps: during a period suitable for grafting of a dormant tree body, cutting skeleton branches with feeble continued branches to smooth branches of two or more years; and performing top grafting of a scion with only one upside leaf bud of the same variety by use of a single-bud cutting grafting method, thereby replacing the continued branches of skeleton branches with strong branches from the scion to outwards spread a crown. By virtue of the technology disclosed by the invention, the growth vigor of the feeble skeleton branches can be rapidly enhanced, the crown is further outwards spread, and the yield is improved.
Description
Technical field
The invention belongs to fruit tree cultivation technical field, be specifically related to a kind of method strengthening pergola system pears skeleton branch elongated shoot growing way.
Background technology
Pears horizontal rack cultivation, often because selecting open a business excessive or disease pest of the weak kind of growing way or branch angle to cause harm, cause that major branch, the secondary skeleton branch elongated shoot such as major branch, side shoot form a large amount of bud, growth potential sharply turns overly soft pulse to stopping growing, strong rear weak tree vigo(u)r before being formed, tree crown extension and output increased delay or block.A kind of method strengthening pears skeleton branch elongated shoot growing way is based on the technological invention solving this production problem.Practice fully proves, adopts this technological invention, can quickly strengthen growing way by weakening skeleton branch, further out spreading crown and raising yield.
Summary of the invention
It is an object of the invention to provide a kind of method strengthening pergola system pears skeleton branch elongated shoot growing way.
A kind of method strengthening pergola system pears skeleton branch elongated shoot growing way, summary of the invention includes applicable object, applicable time, retraction position, takes fringe requirement, scion leaf bud towards, connect after management etc..
For achieving the above object, the present invention adopts the following technical scheme that
A kind of method strengthening pergola system pears skeleton branch elongated shoot growing way, pears pergola system pruning process, because of major branch, the secondary skeleton branch elongated shoot such as major branch and side shoot is weak and when tree crown is difficult to further expand, during tree body winter dormancy, skeleton branch elongated shoot is bounced back to before growing way substantially turns weak branch section, and the method taking simple bud cut-grafting at this, height connects 1 same kind only sturdy branch section of simple bud containing leaf bud, substitutes former skeleton branch elongated shoot outward expansion tree crown with the strong branch top that it sprouts pumping.
Damp and hot producing region, south is all can carry out before sprouting to bud in next year after pears are fallen leaves, and dry and cold producing region is extremely freeze-up front after pear tree fallen leaves and skeleton branch weak for elongated shoot is bounced back to life in 2 years or life in 2 years with Smooth branch section place before sprouting to pear flower bud by defrosting in next year.
On same kind plant, clip rugosity 1.0～1.5, leaf bud are in the majority, grow the healthy and strong branch enriched as the branch taking fringe.
In the key end of the branch of retraction, take simple bud cut-grafting method, height connect 1 same kind only containing 1 upside leaf bud scion.
Scion leaf bud sprouts the branch of pumping, and it is straight fixing that growth mid-early stage answers vertical rod to hold up, it is prevented that the growing way that windburn etc. fracture and keep it vigorous, opens to be pulled to become 40-50 ° with horizontal canopy face after the middle and late growth stage is aging.
Beneficial effects of the present invention:
Pears horizontal rack cultivation, elongated shoot is formed a large amount of bud, growth potential sharply turns overly soft pulse extremely dormant major branch, the secondary skeleton branch such as major branch, side shoot, namely within the time of the suitable grafting of tree body rest period, skeleton branch weak for elongated shoot is bounced back to life in 2 years or life in 2 years with Smooth branch section place, take simple bud cut-grafting method, height connect 1 same kind only containing 1 upside leaf bud scion, substitute skeleton branch elongated shoot to spreading crown with its strong prosperous branch top sprouting pumping.
Detailed description of the invention
Embodiment 1
Damp and hot producing region, south is that skeleton branch weak for elongated shoot bounces back to after pears fallen leaves 2 years sliding branch section places of the third contact of a total solar or lunar eclipse.
On same kind plant, clip rugosity 1.0, leaf bud are in the majority, grow the healthy and strong branch enriched as the branch taking fringe.
In the key end of the branch of retraction, take simple bud cut-grafting method, height connect 1 same kind only containing 1 upside leaf bud scion.
Scion leaf bud sprouts the branch of pumping, and it is straight fixing that growth mid-early stage answers vertical rod to hold up, it is prevented that the growing way that windburn etc. fracture and keep it vigorous, opens to be pulled to become 40 ° with horizontal canopy face after the middle and late growth stage is aging.
Embodiment 2
Dry and cold producing region is to skeleton branch weak for elongated shoot bounces back to before freeze-up 3 years sliding branch section places of the third contact of a total solar or lunar eclipse after pear tree fallen leaves.
On same kind plant, clip rugosity 1.5, leaf bud are in the majority, grow the healthy and strong branch enriched as the branch taking fringe.
In the key end of the branch of retraction, take simple bud cut-grafting method, height connect 1 same kind only containing 1 upside leaf bud scion.
Scion leaf bud sprouts the branch of pumping, and it is straight fixing that growth mid-early stage answers vertical rod to hold up, it is prevented that the growing way that windburn etc. fracture and keep it vigorous, opens to be pulled to become 50 ° with horizontal canopy face after the middle and late growth stage is aging.
Embodiment 3
Damp and hot producing region, south is that skeleton branch weak for elongated shoot bounces back to after pears fallen leaves 3 years sliding branch section places of the third contact of a total solar or lunar eclipse.
On same kind plant, clip rugosity 1.5, leaf bud are in the majority, grow the healthy and strong branch enriched as the branch taking fringe.
In the key end of the branch of retraction, take simple bud cut-grafting method, height connect 1 same kind only containing 1 upside leaf bud scion.
Scion leaf bud sprouts the branch of pumping, and it is straight fixing that growth mid-early stage answers vertical rod to hold up, it is prevented that the growing way that windburn etc. fracture and keep it vigorous, open after the middle and late growth stage is aging be pulled at 45 ° with horizontal canopy face.
Controlled trial
In mid-January, 2013, it is that 4 × 4m, 3 years life face pergola system emerald pears skeleton branch elongated shoots of the age of tree are seriously weak to Jianning County Lv Yuanguo industry company limited at seeding row spacing to plant, take the technology of the present invention, winter in 2013, tree crown relatively compareed expansion more than 1.5m, within 2015, single plant yield relatively compares raising more than 10.5kg, and effect is extremely notable.
The foregoing is only presently preferred embodiments of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to the covering scope of the present invention.
