Description

Quick grafting tool for dragon fruit seedlings

Technical Field

The utility model relates to a plant breeds technical field fast, concretely relates to quick grafting's of dragon fruit young seedling instrument.

Background

Pitaya is a typical tropical and subtropical fruit originating from the tropical rainforest and desert zones of countries such as mexico, costa rica, nicaraga, and cuba in central america. Although the planting of dragon fruits in China starts late, the development momentum is not a little great. Taiwan is an early region for cultivating dragon fruits in China, has a history of decades and has a high planting level; the provinces such as Hainan, Guangdong, Guangxi, Fujian and Guizhou have been planted in recent years and form a certain cultivation scale.

The dragon fruit is a novel fruit which is beautiful in shape, bright in color, fine and refreshing in flavor, unique in fragrance and beneficial to human health, contains rich sugar, organic acid, protein, amino acid, vitamin, mineral elements and dietary fiber and has high economic value. At present, the varieties of dragon fruits are very various, new varieties are continuously promoted to be new, the variety bank of the dragon fruits is continuously expanded by technical means such as crossbreeding, and the varieties cultivated in Taiwan are particularly good at eye, and a plurality of high-yield and high-quality varieties are continuously developed, so that a plurality of growers are good at life. In contrast, although the planting area of the dragon fruit is continuously enlarged in continental areas of China, the variety cultivation of the dragon fruit is still at a lower level, and the star variety which is cultivated autonomously is lacked. The reason for this situation is that besides late planting and low research, the method lacks a corresponding cultivation technology and is also a main limiting factor that many growers cannot breed new varieties quickly. In order to obtain a new hybrid variety, a common method is to perform cutting seedling raising by purchasing a stem section of the new variety, but the stem section of the new variety is high in price and is difficult to bear by a common grower; and secondly, the seedlings are raised through new fruit seeds, and a large number of seedlings can be obtained through seed seedling raising, but the defect is that the seedling raising period is overlong, and the fruit bearing can be realized only in four or five years. Therefore, how to make the young seedlings of the dragon fruits grow quickly to shorten the fruit bearing time is a technology which is eagerly mastered by many growers and is also the key to solve the problem of crossbreeding.

SUMMERY OF THE UTILITY MODEL

To sum up, for overcoming prior art's not enough, the utility model aims to solve the technical problem that an instrument of quick grafting of dragon fruit young seedling is provided, it has effectively improved the efficiency of grafting.

The utility model provides an above-mentioned technical problem's technical scheme as follows: a quick grafting tool for dragon fruit seedlings comprises a first grafting pipe and a second grafting pipe, wherein the first grafting pipe and the second grafting pipe are hollow metal pipes with the same wall thickness, and the inner diameter of the first grafting pipe is smaller than that of the second grafting pipe; one end of the first grafting pipe is a diagonal cut, and the other end of the first grafting pipe is a flat cut; the two ends of the second grafting pipe are sharp flat openings.

Further, the first grafting pipe is 10-12cm long and 3-3.5mm in outer diameter.

Further, the second grafting pipe is 10-12cm long and 4-4.5mm in outer diameter.

Further, the wall thickness of the first grafting pipe and the second grafting pipe is 0.1-0.15 mm.

The utility model has the advantages that: the first grafting pipe and the second grafting pipe are matched for use, because of the pipe diameter difference between the first grafting pipe and the second grafting pipe, the hole formed on the stock is smaller, the stem diameter of the modified scion is larger, and after the first grafting pipe and the second grafting pipe are connected, the scion is in close contact with the stock and is not easy to be separated after water loss, so that the grafting survival rate is effectively improved; in addition, after the scions for grafting are cut from the seedlings, the complete root systems are reserved, the seedlings can still sprout new buds and can be used for grafting after growing to a certain degree, continuous scions are provided for variety grafting, and the utilization rate of seedling resources is improved.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1 and 2, a tool for rapid grafting of dragon fruit seedlings comprises a first grafting pipe 2 and a second grafting pipe 3, wherein the first grafting pipe 2 and the second grafting pipe 3 are hollow metal pipes with the same wall thickness, and the inner diameter of the first grafting pipe 2 is smaller than the inner diameter of the second grafting pipe 3. One end of the first grafting pipe 2 is a diagonal cut, the other end of the first grafting pipe is a flat cut, the length of the first grafting pipe is 10-12cm, the outer diameter of the pipe is 3-3.5mm, namely, the first grafting pipe 2 is chamfered or sharpened at a position 20mm away from the pipe orifice, and finally, the pipe orifice is a sharp inclined plane pipe orifice (the pipe orifice forms a knife edge). The two ends of the second grafting pipe 3 are sharp flat openings (the pipe orifice forms a knife edge), the length of the second grafting pipe is 10-12cm, and the outer diameter of the second grafting pipe is 4-4.5 mm. The wall thickness of the first grafting pipe 2 and the second grafting pipe 3 is 0.1-0.15 mm.

The dragon fruit young seedling refers to the dragon fruit seedling that breeds out from the dragon fruit seed, through first grafting pipe 2 with the grafting of quick dragon fruit seedling can be realized to the cooperation of second grafting pipe 3, specifically as follows:
