Embodiment 1
[0071] 1. Materials and methods
[0072] The test was carried out on September 22, 2013 (sunny day) in Baihelin Orchard, Xiema Town, Beibei District. The rootstocks used as base stock mainly include four kinds of rootstocks commonly used in production, namely Ziyang orange, tangerine, trifoliate orange and Citrange, the varieties used as intermediate stock are respectively: trifoliate orange, orange and fragrant orange, wherein the length of intermediate stock is respectively the branch of 5cm and 10cm, and the branch of each length all adopts to connect (the original base portion is cut into the interface) and reversely. Connecting (cutting the original top, that is, adjusting the direction of the branches) for abdominal connection.
[0073] Irrigate the whole vegetative body with water before grafting, carry out routine water, fertilizer and pest management, and check the survival rate after 20 days of grafting. Whether it is straight grafting or reverse grafting, the surviv...
Embodiment 2
[0079] 1. Materials and methods
[0080] Planted in March 2015, grafted in September 2015, and counted in May 2016
[0081] Table 2 Survival rate of direct grafting and reverse grafting of different lengths of intermediate stock and survival rate after regrafting
[0082]
[0083] 2. Experimental results
[0084] As can be seen from Table 2, no matter whether it is cis-connection or reverse connection, the survival rate is higher, and the survival rate of cis-connection is mostly 60%-100%, but the average survival rate is as high as 90%; the survival rate of reverse connection is still 90%. 60%-100%, but the average survival rate was 75.14%. The survival rate of regrafting scions on the intermediate stock was as high as 79.26%, while the survival rate of reverse grafting was 60.12%.
[0085] 3. Results
[0086] As can be seen from the above results, as in Example 1, no matter whether it is direct or reverse grafting, the intermediate stock can survive, and the scion gra...

Abstract
The invention belongs to the technical field of grafting, and discloses an orange grafting method, including: collecting and sowing seeds of root stocks; transplanting and culturing seedling of root stocks; performing forward grafting and reversed grafting; perforating a hole in the film at the position, with a bud eye, of each scion with a blade, and bending the grafting stocks to promote germination of nursery stocks; cutting off residual root stocks at the graft unions at the first aging time of sprouts; performing side grafting on bud in summer and autumn since the primary sprouts of intermediate stocks are aged; after the spring of the next year, perforating a hole in the film at each grafting position with the blade, and bending the intermediate stocks to promote germination of seedlings. The orange grafting method is different from the conventional domestic organic grafting methods. With forward and reversed grafting on different stocks, grafting survival can be achieved; bud grafting is performed on the survived reversed-grafted branches to achieve germination and sprouting. The orange grafting method refers to a new method for controlling growth of orange trees and dwarfing crowns of the orange trees, and provides another way to produce high-quality high-yield oranges.
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 reproduction in production, that is, grafting 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. Adopt the grafted plant (consisting of aboveground part scion and underground part rootstock), can keep the excellent character of its scion variety and can utilize the good characteristic of rootstock again. There are many kinds 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, quality,...
