Description

Technical Field

[0001] The invention belongs to the technical field of grape planting, and in particular relates to a sealing connector for grape grafting and seedling cultivation. Background Art

[0002] Grafting is one of the artificial vegetative propagation methods of plants. That is, the branch or bud of one plant is grafted onto the stem or root of another plant, so that the two parts connected together grow into a complete plant. Grafting methods are divided into bark grafting and bud grafting. When grafting, the cambium of the scion and the rootstock should be closely combined to ensure the survival of the scion. The grafted branch or bud is called a scion, and the grafted plant body is called a broken wood or a platform. In the process of planting grapes, grafting can improve the disease resistance, cold resistance, waterlogging resistance and ability to adapt to adverse soil conditions of grapes. Several commonly used methods of grape grafting include tongue grafting, cleft grafting, rooted seedling grafting and grafting cutting propagation. Among them, tongue grafting is a common grafting method. The base of the scion is cut into an inclined surface with a length of about 3 cm. Cut down a knife at 1 / 3 of the inclined surface, with a depth of 1.5-2.0 cm. Cut down from the top of the cut surface to form a double tongue-shaped section. The rootstock is also cut in the same way. Insert the cut surfaces of the scion and rootstock together.

[0003] Since the connection between the rootstock and the scion is tightly combined in this grafting method, the wrapping is relatively simple, which makes it easy to cause the problem of insufficient sealing due to the lack of experience of the operator during the wrapping process, affecting the survival rate of the subsequent grafting.

[0004] Based on this, a sealing connector for grape grafting and seedling cultivation is proposed. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-3 As shown, the present invention provides a technical solution: a sealed connector for grape grafting and seedling cultivation, comprising a sealed connection sleeve 1, wherein the sealed connection sleeve 1 is composed of a lower sleeve 11 and an upper sleeve 12 which are fixedly connected to each other, wherein the lower sleeve 11 and the upper sleeve 12 are both made of a transparent heat shrinkable tube, and the inner diameter of the lower sleeve 11 is greater than the inner diameter of the upper sleeve 12;

[0035] The lower sleeve 11 is sleeved on the outside of the rootstock during use, and the upper sleeve 12 is sleeved on the outside of the scion during use. Since the lower sleeve 11 and the upper sleeve 12 are both made of transparent heat shrinkable tubes, a hot air gun can be used to act on the outside of the sealing connection sleeve 1 to make the sealing connection sleeve 1 shrink naturally, thereby achieving a natural sealing operation.

[0036] In order to facilitate the use of the grafting method in which one side of the rootstock and the scion are aligned, one side of the lower sleeve 11 and the upper sleeve 12 are aligned, and a positioning auxiliary line 13 is provided on the aligned side of the lower sleeve 11 and the upper sleeve 12. The positioning auxiliary lines 13 are respectively nested in the inner walls of the aligned sides of the lower sleeve 11 and the upper sleeve 12, and the positioning auxiliary lines 13 are made of elastic strips. The positioning auxiliary lines 13 can naturally shrink and adjust during the heat shrinkage of the lower sleeve 11 and the upper sleeve 12, thereby improving the accuracy of the connection position of the lower sleeve 11 and the upper sleeve 12 during use.

[0037] A first sealing connection mechanism 2 is fixed to the bottom end of the lower sleeve 11, and a second sealing connection mechanism 3 is fixed to the top end of the upper sleeve 12;

[0038] The first sealing connection mechanism 2 includes a flexible ring 21, a connecting rope ring 24 and a connecting rope 25. The bottom end of the sealing connection sleeve 1 is fixed on the flexible ring 21. A first airbag gasket 22 is arranged on the inner side of the flexible ring 21 near the top end. A second airbag gasket 23 is arranged on the inner side of the flexible ring 21 near the bottom end. The first airbag gasket 22 and the second airbag gasket 23 in the flexible ring 21 are fixedly connected with charging and discharging ports. The gas pressures in the first airbag gasket 22 and the second airbag gasket 23 can be adjusted respectively through the charging and discharging ports, thereby avoiding damage to the stock skin caused by excessive force of the connecting rope 25 during use, thereby improving the flexibility of the first sealing connection mechanism 2 during use.

[0039] A plurality of connecting rope rings 24 are pasted at equal intervals in the middle of the outer ring of the flexible ring 21. The connecting rope 25 passes through the connecting rope rings 24 in turn and is connected to the outside of the flexible ring 21. By tightening the connecting rope 25, a sealed and stable connection between the first sealing connection mechanism 2 and the rootstock epidermis can be completed.

[0040] The second sealing connection mechanism 3 includes an elastic ring 31, an anti-slip strip 32 and an auxiliary tightening rope 34. The elastic ring 31 is fixed to the top of the sealing connection sleeve 1, and anti-slip strips 32 are provided at the top and bottom ends of the elastic ring 31. A plurality of auxiliary rings 33 are pasted at equal intervals outside the elastic ring 31. The auxiliary tightening rope 34 passes through the auxiliary rings 33 in turn, and the tightening and sealing operation of the elastic ring 31 is completed through the auxiliary tightening rope 34.

[0041] In order to facilitate connection, the inner diameter of the flexible ring 21 is the same as that of the lower sleeve 11 , and the inner diameter of the elastic ring 31 is the same as that of the upper sleeve 12 when in a natural state.

[0042] In order to facilitate self-adjustment and contraction of the distance between adjacent connecting rope rings 24 and auxiliary rings 33 during use, the connecting rope rings 24 are glued to the outside of the flexible ring 21 by glue, and the auxiliary ring 33 is glued to the outside of the elastic ring 31 by glue. The connecting rope rings 24 and the auxiliary rings 33 are annular structures made of low-elastic rubber.

[0043] In order to prevent the connecting rope 25 or the auxiliary tightening rope 34 from falling off during use, anti-falling blocks are provided at the ends of the connecting rope 25 and the auxiliary tightening rope 34. The outer diameter of the anti-falling block at the end of the connecting rope 25 is larger than the inner diameter of the connecting rope ring 24, and the outer diameter of the anti-falling block at the end of the auxiliary tightening rope 34 is larger than the inner diameter of the auxiliary ring 33.

[0044] In order to facilitate the grafting of grape branches of different sizes, the length of the sealing connection sleeve 1 is set between 10-15 cm, and the lengths of the lower sleeve 11 and the upper sleeve 12 are the same.

[0045] The method for using the sealed connector for grape grafting and seedling cultivation comprises the following steps:

[0046] S1. Before use, the first sealing connection mechanism 2, the sealing connection sleeve 1 and the second sealing connection mechanism 3 are sequentially passed through the grape rootstock to be grafted, and then the rootstock is processed before grafting, that is, flattened and cut, and then the scion with the beveled surface is clamped on the top of the treated rootstock, and one side of the rootstock and the scion are aligned;

[0047] S2, under the action of artificial external force, the aperture of the second sealing connection mechanism 3 is enlarged, and the second sealing connection mechanism 3 is moved upward to pass through the scion, and the positioning auxiliary line 13 of the sealing connection sleeve 1 is aligned with the alignment side of the stock and the scion during the upward movement, and the second sealing connection mechanism 3 drives the upper sleeve 12 to be sleeved on the outside of the scion and then stops during the upward movement;

[0048] S3, then tighten the connection rope 25 under the action of external force, so that the first sealing connection mechanism 2 is sealed and fixedly connected to the rootstock under the action of the connection rope 25;

[0049] S4, then use a hot air gun to act on the sealing connection sleeve 1, so that the sealing connection sleeve 1 naturally shrinks and is tightly and sealingly connected to the outer surfaces of the stock and the scion, completing the sealing connection between the sealing connection sleeve 1 and the stock and the scion;

[0050] S5. Finally, external force is used to tighten the auxiliary tightening rope 34 to tighten the second sealing connection mechanism 3, so as to complete the sealing connection between the second sealing connection mechanism 3 and the scion, thereby completing the sealing connection operation at the grape grafting seedling connection point.
