Method for grafting and transforming old fruit trees

Abstract

The invention belongs to the technical field of agriculture and in particular discloses a method for grafting and transforming old fruit trees. The method has the following beneficial effects that: transformation of inferior varieties to fine varieties is realized by transforming old and inferior fruit trees and big trees; the method is a technical innovation; after grafting is successful, the fruit branches in the same year can grow to 1.2-1.4 meters, the fruit trees can obtain adequate nutrients, sick trees, weak trees and dead trees are reduced, crowns can be rapidly recovered, and the grafted fruit trees can shape up in one year and blossom and fruit in the next year and the yield is recovered. The method is simple and has strong operability; the crowns in the same year can be recovered through top grafting; high yield can be obtained in the next year; the aims of early fruition, early high yield and high economic benefits are achieved; and the method is suitable for wide popularization and application.

Description

(1) Technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for grafting and transforming old fruit trees. (2) Background technology [0002] Using new varieties to replant young and middle-aged large fruit trees with poor varieties is a major problem that must be paid attention to in the current fruit tree renewal. Because the varieties do not meet the current market demand, many fruit farmers have lost management, and a large number of trees have been plowed. The big tree was destroyed only because of the backward variety; many people also tried to replace the head with high grafting, but the traditional high grafting method, because there are too few grafted branches, the nutrition produced by the leaf area cannot meet the needs of the root system of the big tree. Causes a large number of root system to die, so in the next year after grafting, it often leads to unbalanced growth between the tree and...

[0002] Using new varieties to replant young and middle-aged large fruit trees with poor varieties is a major problem that must be paid attention to in the current fruit tree renewal. Because the varieties do not meet the current market demand, many fruit farmers have lost management, and a large number of trees have been plowed. The big tree was destroyed only because of the backward variety; many people also tried to replace the head with high grafting, but the traditional high grafting method, because there are too few grafted branches, the nutrition produced by the leaf area cannot meet the needs of the root system of the big tree. Causes a large number of root system to die, so in the next year after grafting, it often leads to unbalanced growth between the tree and the tree and the tree dies; even if it survives, it greatly delays the fruiting period and cannot form a crown; Forcing the fruiting part to move up, causing great difficulty for management, not suitable for the needs of sightseeing and picking
