Embodiment 1

[0041] Example 1, This embodiment is the implementation of the olive wedge grafting method in spring

[0042] Grafting time: April 15th to April 18th, 2014

[0043] Grafting steps:

[0044] 1. Scion collection: The mother tree for collecting cuttings should be an adult plant of an excellent variety with high yield, stable yield, strong growth, and no pests and diseases. Select the lignified branches in the middle and upper parts of the canopy, with full growth, straight branches, and full buds. ~2-year-old shoots are used as scions.

[0045] 2. Scion treatment: Scion strips used in the growth period for grafting can be used as they are harvested. After cutting from the mother tree, the leaves and young shoots should be cut off immediately to protect the axillary buds and reduce water evaporation. The total length of the remaining petiole and blade remains at about 1.0cm, and the length of the scion is cut to 5.0~6.0cm.

[0046] 3. Rootstock selection and rootstock cutting:...

Embodiment 2

[0055] Example 2, This embodiment is the implementation of the olive wedge grafting method in spring

[0056] Grafting time: April 25th to April 30th, 2014

[0057] Grafting steps:

[0058] 1. scion collection: with embodiment 1;

[0059] 2. Scion treatment: The scion used for grafting is an excellent variety from a different place. After the scion is cut from the mother tree, the leaves and young shoots should be cut off immediately to protect the axillary buds and reduce water evaporation. The total length of the remaining petioles and leaves is kept at about 1.0 cm, and the length of the scion is cut to 5.0-6.0 cm; during short-term storage and transportation of the scion in different places, wrap it with a damp cloth and film, and store it in a cool place or store it In a refrigerator at a temperature of 10-15°C.

[0060] 3. stock selection, cut anvil: with embodiment 1;

[0061] 4. cut bud: with embodiment 1;

Embodiment 3

[0069] Example 3, This embodiment is the implementation of the olive wedge grafting method in spring

[0070] Grafting time: May 5th to May 10th, 2014

[0071] Grafting steps:

[0072] 1. Scion collection: Although the mother tree that collects cuttings in winter has entered the dormant period, it must also be an adult plant of high-yield, stable yield, robust growth, and no pests and diseases. Select the lignified branches in the middle and upper parts of the canopy to grow fully, 1-2 year old branches with straight branches and full buds are used as scions;

[0073] 2. Scion treatment: After cutting the scion from the mother tree, the leaves and young shoots should be cut off immediately to protect the axillary buds and reduce water evaporation. The total length of the remaining petioles and leaves is kept at about 1.0cm, and the length of the scion is cut to 5.0-6.0cm; the storage time of the scion during the dormant period is longer, and the wound of the scion should b...

Abstract

The invention discloses a wedge-shaped scion grafting propagation method for olea europaea L.. The method includes the steps of stock selection, scion collection, scion treatment, scion storage, grafting and management after grafting. The method includes the specific steps that annual or biennial seedlings or cutting seedlings which are robust in tree body growth, intact in trunk, free of pest and disease damage and high in land adaptability and affinity are selected to be used as the stock; the middle and upper portions of the peripheries of crowns of good-variety adult plants which are high in yield, stable in yield, robust in growth and free of pest and disease damage are collected, lignified and straight-through growth is achieved, and annual or biennial branches with full leaf buds are selected to serve as scions; splitting openings are pried open through a cleft grafting cutter, the scions are slightly inserted into stock slit gaps, and scion forming layers are made to align stock forming layers; the upper ends of the scions are scabbed in crude by 0.2-0.5 cm; connectors are wrapped upwards by plastic thin-film bars from the lower portions of the connectors after the scions are inserted. The survival rate of olea europaea L. seedlings grafted through the method reaches up to 80%, the good properties of seed trees are kept and continued, the stress resistance and adaptability of olea europaea L. nursery-grown plants can be improved obviously, the tree vigor can be recovered, and varieties can be updated.

Description

technical field [0001] The invention belongs to the technical field of tree propagation, in particular to an olive wedge-shaped graft propagation method. Background technique [0002] Olive (Oleaeuropaea L.) is a famous subtropical fruit tree and an important world economic forest tree. The cultivated varieties have high edible value and are rich in high-quality edible vegetable oil-olive oil. Olive oil is a traditional product with a history of thousands of years and enjoys the reputation of "Queen of Vegetable Oils". In the past 20 years, the production and sales of olive products have continued to boom, which is due to the advancement of science and technology that has deepened people's understanding of it. In view of this, countries all over the world in the subtropical zone have shown strong interest in introducing olives. my country's large-scale introduction of olives began in 1964. The Bailongjiang River Valley in Longnan, Gansu Province is the best suitable area f...
