Embodiment 1

[0062] A kind of pitaya grafting method, it comprises:

[0063] Step 1, the variety selection of rootstock and scion: the rootstock is Liangtianchi, a kind of wild dragon fruit, and the scion is Ecuadorian dragon fruit;

[0064] Step 2, processing of rootstocks: select disease-free and robust mature branches of dragon fruit as rootstocks, and require rootstock branches to grow for more than half a year, use a conventional machete to cut off a section of branches as rootstocks, and cut off the mesophyll tissue at the root of the rootstock , exposing the woody white vascular bundle, which is the base of the rootstock; cutting a stepped grafting port with a flat cut surface on the edge of the rootstock stem;

[0065] Step 3. Treatment of double-bud scions: Select the mature branches of Ecuadorian dragon fruit that are disease-free and strong, and cut the scion with double buds on the edge of Ecuadorian dragon fruit. The scion bud eyes are required to be full. correspond;

Embodiment 2

[0069] A kind of pitaya grafting method, it comprises:

[0070] Step 1, the variety selection of rootstock and scion: rootstock is Chinese Taiwan Jindu 450 dragon fruit, and scion is Ecuador dragon fruit;

[0071] Step 2, the processing of rootstock: choose the old and mature branches of Jindu 450 dragon fruit in Taiwan, China, which are disease-free and strong, as the rootstock, and the growth time of the rootstock branches is required to be more than half a year. The mesophyll tissue exposes the woody white vascular bundle, which is the base of the rootstock; a step-shaped grafting port with a flat section is cut on the edge of the rootstock stem;

[0072] Step 3. Treatment of double-bud scions: Select the mature branches of Ecuadorian dragon fruit that are disease-free and strong, and cut the scion with double buds on the edge of Ecuadorian dragon fruit. The scion bud eyes are required to be full. correspond;

[0073] Step 4, grafting treatment: Align the incision of the ...

Embodiment 3

[0076] A kind of pitaya grafting method, it comprises:

[0077] Step 1, the variety selection of rootstock and scion: rootstock is Chinese Taiwan Jindu 450 dragon fruit, and scion is Ecuador dragon fruit;

[0078] Step 2, the processing of rootstock: select disease-free and robust Chinese Taiwan Jindu 450 dragon fruit mature branches as rootstock, require the rootstock branch growth time to be more than half a year, cut off a section of 50 cm long branch with conventional machete as rootstock, cut The length of the mesophyll tissue at the root of the rootstock is 3 cm, exposing the wooden white vascular bundle, and the vascular bundle is the base of the rootstock; a step-shaped grafting joint with a smooth cut surface is cut out on the edge of the rootstock stem, and the grafting joint is specifically treated It is: with a conventional machete, from the top of the rootstock, cut flatly at the n centimeter thickness of the mesophyll tissue of the edge, and the incision length i...

Abstract

The invention discloses a dragon fruit grafting method which comprises the following steps: I, selecting varieties of a rootstock and a scion; II, performing rootstock treatment, namely cutting a section of a plant twig as the rootstock, cutting off mesophyll tissue at the root part of the rootstock, exposing wooden white vascular bundles which are base parts of the rootstock, and cutting a stair-shaped grafting hole of which the cut surface is flat on the ridge of a rootstock stem; III, performing double-bud scion treatment, namely cutting a scion with double buds, wherein the cut part of thescion takes the shape of a Chinese word Ao and has a size corresponding to that of the grafting hole; IV, performing grafting treatment, namely aligning the cut part of the scion to the grafting holeof the rootstock, pressing the scion till the cut part is completely fitted to the grafting hole, and performing bundling and fixing, so as to obtain a grafting seedling; and V, performing grafting seedling culture, namely inserting the base part of the rootstock of the grafting seedling into soil, and performing culture, wherein it means grafting succeeds after the rootstock has roots and scionbuds germinate. The grafting method disclosed by the invention is high in survival rate, rapid in grafting speed and small in workload, the grafting time can be shortened, and the yield and the growthspeed of a scion dragon fruit variety can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of dragon fruit grafting. More specifically, the present invention relates to a kind of dragon fruit grafting method and special cutter thereof. Background technique [0002] Dragon fruit is an important tropical economic crop in China, mainly in Hainan, Guangxi, Guangdong and Guizhou. The current planting area is about 1 million mu. [0003] The current grafting method of dragon fruit is mainly single-bud V-shaped mouth insertion or embedded grafting. The single-bud V-shaped mouth is inserted or embedded for grafting, and the stock used is a rooted rootstock that has been cultivated. The specific method is to cut the scion into a pointed shape, and the rootstock is grafted with a V-shaped joint. The shortcoming of this method has 1, adopts single-bud grafting, if scion bud development is not good, can cause grafting to fail; The contact area is small, which is not conducive to grafting survival and nutri...
