Top grafting method for changing species of grown orange with leaves in summer high temperature

Abstract

A high-position grafting technique at high-temp season (the summer) for orange tree includes such steps as choosing the scion with leaves, cutting on stock, inserting the scion in the cut, banding with film. Its advantages are high temp (30 deg.C) and high survival rate (90% or more).

Description

technical field [0001] The invention relates, in particular, to a high-temperature grafting and replanting method for adult citrus with leaves in summer. Background technique [0002] Judging from the current production of citrus for high-grain grafting and planting, the success rate of young citrus trees less than ten years old is relatively high. When using the same grafting method to carry out high-grafting and replanting of adult citrus over ten years old, the grafting survival rate becomes lower as the tree age increases, generally below 10%, and most of them have no use value in production. The surviving scions will not shoot after surviving, and they are considered in the industry to be old trees that are not suitable for grafting and replanting. Since young citrus under ten years old are still in the developmental stage dominated by vegetative growth, high success rate can be achieved by using several grafting methods commonly used in nursery production for high gra...

Problems solved by technology

Several grafting methods commonly used at present can only be suitable for the temperature of citrus grafting below 30°C, and the temperature conditions in summer are above 30°C, which is a high temperature forbidden area for grafting.
