Description
Technical Field
The invention belongs to the technical field of dragon fruit vegetative propagation, and particularly relates to a dragon fruit grafting method.
Background
The pitaya is a tropical plant of family Cactaceae, genus Petasites or genus Serpentis, the fruit is oval, rich in natural red pigment and anthocyanin, rich in nutrition, including calcium, potassium, magnesium, phosphorus, iron, manganese, zinc, copper and other mineral elements, and medicinal substances can be extracted from the flowers and branches. The most adopted propagation techniques in the current production comprise cutting, grafting and isolated culture techniques.
Currently, the grafting technology of dragon fruits mainly comprises the following technologies. A parallel connection method: transversely cutting the upper end of the stock at a proper position by a knife, flatly cutting the base part of the scion, mutually matching the cuts of the stock and the scion, adhering the scions together aiming at the cambium, and then bundling the scions by cotton threads or fixing the scions by toothpicks; a tongue connection method: longitudinally cutting a shallow crack at the top of the stock, cutting the tail end of the scion into a wedge shape, immediately inserting the wedge shape into the crack of the stock, fixing the wedge shape, and sleeving a plastic bag to keep air humidity; wedge jointing method: transversely cutting the top end of the stock by a knife, longitudinally cutting a crack at the transversely cut central part, cutting the tail end of the scion into a wedge shape, inserting the cut scion into the crack of the stock, and enabling the stock to be matched with the vascular bundle of the scion as much as possible; the approach method comprises the following steps: the edges of one side of the scion with a certain length are cut flat, the edges of one side of the stock are removed, the lengths of the scion and the stock are matched, and then the cut scion is tightly close to the stock and is fixed.
As can be seen, the existing dragon fruit grafting method needs a certain grafting experience, uses more dangerous tools such as cutters and the like, and has more operation links and higher technical requirements. Meanwhile, when the grafting is carried out by adopting the methods, the grafting section is large, the interface is obvious, the shape of the commercial seedling is easy to be inconsistent, the wound of the plant is difficult to heal, the wound infection causes ulcer and the like, and the wound can be enlarged, so that the plant is dead.

In order to achieve the above purpose, the invention provides the following technical scheme:
a dragon fruit grafting method comprises the following steps: and removing the primary tender bud on the stock, taking the picked tender bud to be grafted as a scion, grafting the scion to the primary tender bud part of the stock, and fixing to finish grafting.
Preferably, the grafting period is when the tender bud of the dragon fruit grows to 3-5 cm.
Preferably, the method for removing the original tender shoots of the rootstocks and picking the tender shoots to be grafted comprises the following steps: slowly lifting and rotating the tender shoot in the growth direction to separate the fleshy stem of the tender shoot from the tissue of the stock plant, and keeping the woody pith or part of the woody pith of the tender shoot on the stock plant.
Preferably, the grafting operation is: and (3) inserting the hollow tender bud to be grafted into the position aiming at the wood marrow of the original tender bud of the stock until the hollow tender bud is superposed with the thorn seat of the original tender bud of the stock.
Preferably, the fixing mode is as follows: and fixing the grafted tender bud and the stock mother branch by using a rubber band or an adhesive tape.
More preferably, after the fixation, a moisturizing material is applied to the grafted portion.
Compared with the prior art, the invention has the following beneficial effects:
the invention provides a dragon fruit grafting method, in particular to a natural grafting method for dragon fruit sprouts, which is simple to operate compared with the traditional methods of flat grafting, tongue grafting, wedge grafting, inarching and the like, the grafting is carried out on the growing positions of the sprouts, a mother plant is not damaged, the meristematic tissue of the dragon fruit sprouts is strong in activity and grafting affinity, the average survival rate of grafted seedlings after grafting by the method is higher than 90%, the grafted seedlings grow fast, the practicability is high, and the operation is convenient for various personnel without grafting bases.

Detailed Description
The invention provides a dragon fruit grafting method, which comprises the following steps: and removing the primary tender bud on the stock, taking the picked tender bud to be grafted as a scion, grafting the scion to the primary tender bud part of the stock, and fixing to finish grafting.
The dragon fruit variety is not specially limited, and the grafting method is suitable for most of current commercial or cultivated varieties, including field varieties and potted varieties.
According to the invention, the grafting period is preferably when the tender shoot of the dragon fruit grows to 3-5cm, and the grafting is further preferably when the tender shoot of the dragon fruit grows to 4 cm.
The method for preferably removing the original tender shoots of the rootstocks comprises the following steps: the tender shoot is slowly lifted and rotated according to the growth direction, and is separated from the woody marrow tissue of the mother plant, so that the woody marrow or part of the woody marrow of the tender shoot is kept on the mother plant. The method for picking the tender shoots to be grafted is the same as the method. The wood pith refers to the wood forming layer of the dragon fruit.
In the preferred grafting process, the hollow tender bud to be grafted is inserted to the wood marrow position of the original tender bud of the stock until the hollow tender bud coincides with the thorn seat of the original tender bud of the stock.
The method preferably performs fixation after grafting, and fixes the grafted tender bud and the stock mother branch by using a rubber band or an adhesive tape; more preferably, after fixation, a moisturizing material is applied to the grafted part to moisturize the grafted part. The preferred moisturizing material of the invention is one of sealing wax, vaseline or mud; more preferably, the moisturizing material is petrolatum.
The technical solutions provided by the present invention are described in detail below with reference to examples, but they should not be construed as limiting the scope of the present invention.
