Method for top grafting of dragon fruits

Abstract

The invention provides a method for top grafting of dragon fruits. The method comprises the following steps: selecting a grafting rootstock and scions; sterilizing a first stainless steel pipe, a second stainless steel pipe and a cutter by using alcohol; vertically inserting the first stainless steel pipe into a succulent part of a vascular bundle for at least 3cm by aiming at the vascular bundle in a rootstock cuttage grafting end; performing ring cutting for one cut on the rootstock cuttage grafting end by using the cutter, removing cut-off succulent parts to expose the vascular bundle with a length of 3cm, wherein the exposed vascular bundle is called a butt joint part; enabling the second stainless steel pipe to penetrate through a whole scion along the length direction of the scion by aiming at a vascular bundle in the scion to ensure that the whole vascular bundle in the scion falls off and enters a through hole of the second stainless steel pipe so as to obtain a hollow scion; inserting the hollow scion into the butt joint part of the rootstock to ensure that the scion and the rootstock share one vascular bundle; and fixing a connection part between the hollow scion and the rootstock by using an adhesive tape to complete tandem connection. By adopting the method provided by the invention, the time for bringing a fine variety into production is greatly shortened, an income can be obtained relatively quickly, the survival rate is high, the fruit setting rate is increased, and fruits are big.

Description

technical field [0001] The invention relates to the field of plant grafting, in particular to a method for high-level grafting of dragon fruit.

Problems solved by technology

[0004] In the prior art, the output of the old dragon fruit is low, the cost is high, the benefit is not good, and artificial pollination is required. If it is cut off and replanted, it will waste manpower, material resources, funds, etc.
