Embodiment 1

[0044] 1) Select the root tree: choose a young olive tree that has grown for two years as the root tree, and cut off the trunk of the root tree at 50cm from the ground;

[0045] 2) Select the scion: collect the middle part of the canopy of the high-yield, stable-yield, and high-quality adult olive mother tree, and the mature autumn shoots of the previous year as the scion;

[0046] 3) Scarfing: The temperature is 18~25°C, scarfing is carried out in February, and a triangular wedge-shaped joint is cut at a smooth bark of the root tree, and the base of the scion selected in step 2) is cut into a triangular wedge shape with the root tree The corresponding triangular wedge shape of the interface, then embed the base of the scion into the interface of the root tree, align the cambium and tap tightly so that the root tree and the scion are closely fitted;

[0047] 4) Fixing: Use a thin film tape to wrap around and seal from the bottom of the joint to the upper part of the joint, the...

Embodiment 2

[0057] 1) Select the root tree: choose a young olive tree that has grown for two years as the root tree, and cut off the trunk of the root tree at a distance of 60 cm from the ground;

[0058] 2) Select the scion: collect high-yield, stable-yield, and high-quality adult olive mother tree branches that are 1 to 2 years old as the scion;

[0059] 3) Embedding: In April, when the temperature is 18~25°C, cut a triangular wedge-shaped joint at a smooth bark of the root tree, and cut the base of the scion selected in step 2) into a triangular wedge shape with the root tree The corresponding triangular wedge shape of the interface, then embed the base of the scion into the interface of the root tree, align the cambium and tap tightly so that the root tree and the scion are closely fitted;

[0060] 4) Fixing: use a thin film tape to wrap and seal from the bottom of the joint to the upper part of the joint, then fix the film tape to the root tree, and then cover the joint with a film b...

Embodiment 3

[0070] 1) Select the root tree: choose a low-yield or fruitless olive tree as the root tree, and cut off the root of the root tree at 80cm from the ground;

[0071] 2) Scion selection: collect high-yield, stable-yield, and high-quality adult olive mother trees in the middle of the canopy, and the mature autumn shoots of the previous year;

[0072] 3) Scarf grafting: at a temperature of 18-25°C, trunk grafting is carried out in March. Before grafting, 1 to 2 weak branches are left on the main trunk of the rootstock tree as pumping branches, and then a triangle is cut on the smooth bark of 4 places on the rootstock tree. Wedge-shaped interface, and then correspondingly intercept the scion, select 4 scions selected in step 2), cut the base of each scion into a triangular wedge corresponding to the triangular wedge interface of the root tree, and then embed the base of the scion into the interface of the root tree correspondingly, aligning Cambium and tapped tightly to make the ro...

Abstract

The invention discloses a scarf joint method of Canarium album ReauschsRaeusch. The method sequentially comprises the following steps of: selecting stock trees, selecting scions, carrying out scarf joint, fixing, managing after scarf joint, and managing the grafted trees which are subjected with to scarf joint for a long term. The scarf joint method of the Canarium album Reaaeuschs has the following advantages of: 1, improving the survival rate, wherein the survival rate of the grafted trees is improved to above 90% from the current 30-50%; 2, realizing dwarfing, wherein the height of the fruit-bearing trees are is descended to below 5 meters from 10 meters; 3, realizing close planting, wherein the plantings at every mu are increased to 30 plants from 12 plants; 4, realizing early bearing, wherein the trial period after planting is decreased to 4 years from 7 years, and the startup time is decreased to 6 years from 10 years; 5, realizing high yield, wherein the yield is improved to 1500 kilograms, but the traditional planting yield per mu is 600 kilograms; and 6, realizing high quality, wherein, comparing with seedling cultivation, a fine variety generation is cultivated through scarf joint with unseparated properties, and fine variety performance can be kept.

Description

technical field [0001] The invention relates to a scarfing method, in particular to an olive tree scarring method. Background technique [0002] olives ( Canarium album Reausch) cultivation traditionally uses olive seeds to sow sexual reproduction. After planting, it takes 7 years for trial production and 10 years for production. The height of the tree is more than 10 meters. The proportion of inferior trees accounts for more than 30%, and the production efficiency is low. Therefore, embedding has become an important technical measure to solve the defects of seed cultivation. Over the past 20 years, olive grafting technology has achieved certain results, but many problems have occurred in the promotion of production. Old and premature decline, less fruit, low yield, no production benefits; split grafting and cutting grafting are adopted for tree height grafting in production, the survival rate is only 30-50%, and the tree body is still tall, with a tree height of about 10...
