Method for grafting olea europaea

Abstract

The invention discloses a method for grafting olea europaea. The method comprises the following steps of (1) preparing a stock; (2) selecting a scion; (3) grafting in March 25th to April 5th, only removing a bark layer on the front surface of the scion without xylem damage, wherein the length of a cutting opening is 1.6-1.8cm, cutting the lower end of the back surface of the scion once in a manner that the cutting angle is 45 DEG, longitudinally cutting the bark layer without xylem damage and the length of the cutting opening is 2-2.4cm at a smooth part of the stock, inserting the scion into the cutting opening of the stock, aligning the scion with a forming layer, bundling with a plastic tape to tight, wherein the scion is provided with 2-3 buds and the length of the scion is 3.5-5cm; (4) managing, keeping the soil wet after grafting, preventing entering of water into the cutting opening, and performing stock breaking in time after the scion sprouts; and (5) when the grafted seedling grows to a length of one meter, performing top breaking. The method for grafting the olea europaea has high survival rate which reaches up to 98% after grafting, and settles a problem of low survival rate after grafting according an existing grafting method. The method for grafting the olea europaea further has advantages of easy operation and high suitability for large-area popularization.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a method for grafting olives. Background technique [0002] Olive (Oleaeuropaea.) is an evergreen tree of the genus Oleaceae Oleaceae. It is a world-renowned tree species for woody oil and fruit. The cultivated species have high edible value and are rich in high-quality edible vegetable oil-olive oil. It is a famous subtropical fruit tree and Important economic trees are mainly distributed in Mediterranean countries, with Greece, Italy, Tunisia and Spain as the concentrated production areas. Small evergreen tree, up to 10 m tall; bark gray. Branches gray or taupe, subcylindrical, with scattered round lenticels, branchlets angular, densely covered with silver-gray scales, nodes slightly compressed. Leaf blade leathery, lanceolate, sometimes oblong-elliptic or ovate, 1.5-6 cm long, 0.5-1.5 cm wide, apex acute to acuminate, with small convex points, base tapering or cunea...

Problems solved by technology

Cuttings are affected by the survival rate and cannot be popularized on a large scale

Although the olive grafting technology is relatively mature, due to many influencing factors, the survival rate is often unsatisfactory
