A kind of method of citrus grafting

Abstract

The invention belongs to the technical field of branch grafting, and discloses a method for citrus grafting; rootstock seed collection and sowing; rootstock seedling transplanting and cultivation; grafting for direct grafting and reverse grafting; Pick a hole in the film at the place where the base stock is bent to promote the germination of seedlings; until the first shoot is mature, cut off the excess stock on the grafting interface; Use small buds for abdominal grafting; after the spring of the second year, use a blade to pick a hole in the film at the place where the buds are grafted, and bend the middle stock to promote seedling germination. The invention changes a method of traditional grafting of citrus in my country. Adopting different rootstocks for positive and negative grafting can achieve graft survival, and grafting can be carried out on the surviving reverse grafted branches again to achieve germination and shoot shooting. It provides a new method for controlling tree vigor and dwarfing tree crowns, and provides another way for producing high-quality and high-yield citrus fruits.

Description

technical field [0001] The invention belongs to the technical field of grafting, in particular to a method for grafting oranges. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Citrus grafting technology is one of the main methods of production reproduction, that is, to graft the branch or bud of one plant to the stem or root of another plant, so that the two parts that are joined together grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. The grafted plant (consisting of the scion on the ground and the rootstock on the ground) can not only maintain the excellent character of the scion variety but also utilize the good characteristics of the rootstock. There are many types of citrus rootstocks, and many factors need to be considered in the selection of rootstocks. Different rootstocks have certain effects on the root system, crown, tree height, yield, qua...

AI Technical Summary

Problems solved by technology

[0006] (1) At present, the source of the main intermediate stock in production is mainly through high-grafting and replanting, using the original eliminated varieties as the intermediate stock, and using the base stock to graft another rootstock and then grafting the scion. There is no seedling raising method;

[0007] (2) At present, all the intermediate anvils in production are connected to the base anvil, and there is no reverse connection of the intermediate anvils on the base anvil.
