Grafting method of gold pear tree

Abstract

The invention discloses a grafting method of a gold pear tree. The grafting method comprises the specific steps of selecting a callery pear tree which is strong and under good field conditions as a stock and immediately grafting the gold pear tree by use of a cut-grafting method after field planting in spring, and after grafting, wrapping with a breathable film or a plastic bag and punching a plurality of pores by use of a needle; during the grafting operations, the grafted branch and the grafting cut should be smooth, the grafted branch is aligned to the grafting cut, and tight binding and high operating speed are required; after the grafted branch grows to 80mm, windproof binding is performed. The grafting method of the gold pear tree is an effective measure to keep the crisp and tender pulp and sweet flavor of the gold pear, improve the unit area efficiency of the fruit trees and inhibit aging and weakness of the tree bodies.

Description

technical field [0001] The invention relates to the field of fruit tree cultivation, in particular to a method for grafting golden pear trees. Background technique [0002] The fruit of golden pear is nearly round or slightly flat, with an average single fruit weighing 250 grams and a large fruit weighing 500 grams. The peel of the unbagged fruit is yellow-green and turns golden yellow after storage. The bagged fruit has light yellow peel, clean fruit surface, and small and sparse fruit spots. The flesh is white, crisp and tender, juicy, with few stone cells, and the core is extremely small. The edible rate is over 95%. The soluble solid content of unbagged fruit is 14% to 16%, and that of bagged fruit is 12% to 15%. The flavor is sweet. The market price is high and the economic benefits are good, so it is very popular among growers and consumers. However, after many years of golden pear bearing fruit, too many joint branches on the main branch are not treated, and the q...

AI Technical Summary

Problems solved by technology

However, after many years of golden pear bearing fruit, too many joint branches on the main branch were not treated, and the quality of nutrition supply of the joint branches was poor, resulting in low fruit quality.

There are too many fruits on the extended branches of each joint branch group. After the branches droop, they have to be renewed repeatedly with the nutrient branches behind. This unreasonable repeated renewal makes the growth of the branches of the tree slow, and the crown cannot quickly cover the entire garden space. Low area efficiency

On the contrary, the renewal of fruiting branches is completely ignored, and all vegetative branches on the back are removed, and the tree is prone to aging and weakness.
