Closed apple orchard intercropping transformation multi-branch inarching one-time forming method

Abstract

The invention discloses a closed apple orchard intercropping transformation multi-branch inarching one-time forming method. The method comprises the following steps of performing interlacing intercropping on a bush closed old orchard, performing variety renewing by adopting a multi-branch inarching one-time forming method, and performing the same operation on unintercropped fruit trees after threeyears, so that the old orchard transformation problem can be effectively solved, closing can be removed, and poor variety replacement with optical variety and variety renewing in the orchard can be realized gradually; according to the method, fruiting after 3 years, high yield after 5 years and low early-stage investment can be guaranteed, the influence on economic benefits in a short period is relatively small, the process is simple, and orchard workers can master the method easily. The multi-branch approach grafting one-time forming method mainly comprises the specific steps of scion collection, scion preservation, rootstock treatment, scion grafting on tree stumps, scion grating, binding after grafting, management after grafting and the like, and specific technological step and parameter setting; and 3-8 scions are combined into a whole, one-time forming is achieved, wind blowing resistance is achieved, survival is easy, the cross section is not dead, and nutrient conveying is fast. Fruiting in 3 years and high yield in 5 years can be realized, and poor variety replacement with optical variety in a short time are realized.

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.
