Wedge-shaped scion grafting propagation method for olea europaea L.

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...
