A one-time molding method for thinning transformation of closed apple orchards with multi-branch abutment

Abstract

The invention discloses a one-time forming method of multi-branch grafting for the transformation of closed apple orchards by thinning. The method adopts interlaced thinning for arborization and closed old orchards, and uses the multi-branch grafting one-time molding method to update its varieties. Three years later, the Performing the same operation on unthinned fruit trees can effectively solve the problem of old orchard transformation, remove canopy closure, and gradually realize the improvement of varieties in the whole orchard, and the renewal of varieties. This method can guarantee 3-year results, 5-year high yield, and low initial investment. It has little impact on short-term economic benefits, and the process is simple and easy for fruit growers to master. Among them, the multi-branch grafting one-time forming method mainly includes specific steps such as collecting scions, storing scions, rootstock treatment, inserting scions on tree stumps, inserting between scions, bandaging after grafting, and management after grafting, as well as process parameter settings. Eight scions are combined into one, forming at one time, wind-resistant, easy to survive, no dead skin in the cross-section, fast nutrient delivery, 3 years of fruiting, 5 years of high yield, realizing the replacement of inferior varieties with superior ones in a short period of time.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a one-time forming method for multi-branch abutment jointing for transformation of closed apple orchard thinning. Background technique [0002] There are roughly four methods for the existing airtight apple orchard renovation technology: one is to update orchards that have lost their renovation value. That is to pull out the original fruit trees, replace the land, and build another orchard; or carry out in-situ renewal, pull out the original fruit trees, undergo appropriate soil treatment as required, and build a new orchard on the original site to develop tree species and varieties suitable for various local conditions. Replacing the plot involves land adjustment, which is difficult; new fruit farmers at the original site have low acceptance, and the initial investment is high, which greatly affects short-term economic income. The second is to carry o...

Problems solved by technology

This method has high technical requirements, and fruit farmers do not have enough knowledge of quality, tree shape, grafting technology, and supporting management technology, which often results in unreasonable tree shape and low survival rate, which restricts the growth of fruit trees and the improvement of farmers' economic benefits.
