Citrus grafting method

Abstract

The invention belongs to the technical field of scion grafting, and discloses an orange grafting method. The orange grafting method comprises the following steps: rootstock seeds are collected and sowed; rootstock seedlings are transplanted and cultured; forward grafting and reverse grafting are carried out; a hole is formed in the position of a film, with a bud eye, of a scion, and a base stock is bent to promote seedling germination; the top end of the rootstock is cut off by a section until the first shoot is aged; after the intermediate stock is subjected to first-time shoot sprouting andaging, small bud side grafting is adopted at the position, 3 cm away from bottom to top, of the intermediate stock in summer and autumn, and the survival rate is investigated 20 days later; and afterthe beginning of spring, a hole is formed in the film at the bud grafting position, the middle stock is bent to promote seedling germination, and the germination rate is investigated one month later.Different rootstocks are adopted for forward and reverse scion grafting to realize grafting survival, bud grafting is conducted on survived reverse grafting branches again to realize germination and shoot sprouting. A new method for controlling tree vigor and dwarfing tree crowns is provided, and another way is provided 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...

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.
