Description

Technical Field

[0001] The present invention belongs to the technical field of grape cultivation, and particularly relates to a sealed connector for grape grafting and seedling raising. Background Technique

[0002] Grafting is one of the artificial vegetative propagation methods of plants. That is, a branch or bud of one plant is grafted onto the stem or root of another plant, so that the two parts joined together grow into a complete plant. The grafting methods are divided into bark grafting and bud grafting. During grafting, the cambium of the scion and the rootstock should be closely combined to ensure the survival of the scion. The branch or bud grafted on is called the scion, and the plant body to be grafted is called the rootstock or stock. During grape cultivation, grafting can improve the disease resistance, cold resistance, waterlogging resistance and the ability to adapt to poor soil conditions of grapes. Several common methods of grape grafting include tongue grafting, cleft grafting, grafting of rooted seedlings and grafting and cutting propagation. Among them, tongue grafting is a common grafting method. The base of the scion is cut into an inclined plane, and the length of the inclined plane is about 3 cm. A cut is made downward at 1 / 3 of the inclined plane, and the depth is 1.5 - 2.0 cm. Cut obliquely downward from the top of the cut surface to form a double-tongue cut surface. The rootstock is also cut in the same way. The cut surfaces of the scion and the rootstock are inserted together.

[0003] Since the connection between the rootstock and the scion in this grafting method is closely combined, the bandaging is relatively simple, but it is easy to cause the problem of insufficient sealing due to the lack of experience of the operator during the bandaging process, which affects the survival rate of the later grafting.

[0004] Based on this, a sealed connector for grape grafting and seedling raising is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a sealed connector for grape grafting and seedling raising in view of the above-mentioned deficiencies of the prior art, so as to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is:

[0007] In a first aspect, a sealed connector for grape grafting and seedling raising includes a sealed connection sleeve, and the sealed connection sleeve is composed of a lower sleeve and an upper sleeve that are fixedly connected and communicated with each other. A first sealed connection mechanism is fixed at the bottom end of the lower sleeve, and a second sealed connection mechanism is fixed at the top end of the upper sleeve;

[0008] The first sealing connection mechanism includes a flexible ferrule, a connecting rope loop, and a connecting rope. The bottom end of the sealing connection sleeve is fixed on the flexible ferrule. A first airbag gasket is arranged near the top end inside the flexible ferrule, and a second airbag gasket is arranged near the bottom end inside the flexible ferrule. A plurality of connecting rope loops are adhesively pasted at equal intervals in the middle of the outer ring of the flexible ferrule. The connecting rope passes through the connecting rope loops in sequence and is connected to the outside of the flexible ferrule.

[0009] The second sealing connection mechanism includes an elastic ferrule, anti-slip strips, and an auxiliary tightening rope. The elastic ferrule is fixed at the top end of the sealing connection sleeve, and anti-slip strips are arranged at both the inner top end and the inner bottom end of the elastic ferrule. A plurality of auxiliary rings are adhesively pasted at equal intervals outside the elastic ferrule. The auxiliary tightening rope passes through the auxiliary rings in sequence, and the elastic ferrule is tightened and sealed through the auxiliary tightening rope.

[0010] As a further description of the present invention, both the lower sleeve and the upper sleeve are made of transparent heat-shrinkable tubes, and the inner diameter of the lower sleeve is larger than that of the upper sleeve.

[0011] As a further description of the present invention, one side of the lower sleeve and the upper sleeve is aligned, and a positioning auxiliary line is arranged on the aligned side of the lower sleeve and the upper sleeve.

[0012] As a further description of the present invention, the positioning auxiliary lines are respectively nested inside the inner walls of the aligned sides of the lower sleeve and the upper sleeve, and the positioning auxiliary lines are made of elastic strips.

[0013] As a further description of the present invention, the inner diameter of the flexible ferrule is the same as the inner diameter of the lower sleeve, and the inner diameter of the elastic ferrule in the natural state is the same as the inner diameter of the upper sleeve.

[0014] As a further description of the present invention, air charging and discharging ports are fixedly communicated with both the first airbag gasket and the second airbag gasket inside the flexible ferrule, and the gas pressure inside the first airbag gasket and the second airbag gasket can be adjusted respectively through the air charging and discharging ports.

[0015] As a further description of the present invention, the connecting rope loops are adhesively pasted on the outside of the flexible ferrule through glue, the auxiliary rings are adhesively pasted on the outside of the elastic ferrule through glue, and the connecting rope loops and the auxiliary rings are ring-shaped structures made of low-elastic rubber.

[0016] As a further description of the present invention, anti-slip blocks are arranged at the ends of both the connecting rope and the auxiliary tightening rope. The outer diameter of the anti-slip block at the end of the connecting rope is larger than the inner diameter of the connecting rope loop, and the outer diameter of the anti-slip block at the end of the auxiliary tightening rope is larger than the inner diameter of the auxiliary ring.

[0017] As a further illustration of the present invention, the length of the sealed connection sleeve is set between 10 - 15 cm, and the lower sleeve and the upper sleeve have the same length.

[0018] Secondly, a method for using a sealed connection head for grape grafting and seedling raising includes the following steps:

[0019] S1. Before use, sequentially pass the first sealed connection mechanism, the sealed connection sleeve, and the second sealed connection mechanism through the grape rootstock to be used for grafting. Then, perform pre - grafting treatment on the rootstock. Then, snap the processed scion onto the top of the processed rootstock, and align one side of the rootstock and the scion.

[0020] S2. Under the action of artificial external force, enlarge the aperture of the second sealed connection mechanism, and move the second sealed connection mechanism upward through the scion. During the upward movement, align the positioning auxiliary line of the sealed connection sleeve with the aligned side of the rootstock and the scion. During the upward movement, the second sealed connection mechanism drives the upper sleeve to sleeve outside the scion and then stops.

[0021] S3. Then, tighten the connecting rope under external force, so that the first sealed connection mechanism is hermetically and fixedly connected to the rootstock under the action of the connecting rope 25.

[0022] S4. Then, use a hot air gun to act on the sealed connection sleeve, so that the sealed connection sleeve naturally shrinks and tightly adheres to and seals the outer surfaces of the rootstock and the scion, completing the sealed connection between the sealed connection sleeve and the rootstock and the scion.

[0023] S5. Finally, use external force to tighten the auxiliary tightening rope to tighten the second sealed connection mechanism, completing the sealed connection between the second sealed connection mechanism and the scion, and thus completing the sealed connection operation at the joint of grape grafting and seedling raising.

[0024] The present invention has the following advantages compared with the prior art:

[0025] 1. The sealed connection sleeve in the present invention is composed of a lower sleeve and an upper sleeve that are fixedly and communicatively connected to each other. Both the lower sleeve and the upper sleeve are made of transparent heat - shrinkable tubes, and the inner diameter of the lower sleeve is larger than that of the upper sleeve. The lower sleeve is sleeved outside the rootstock during use, and the upper sleeve is sleeved outside the scion during use. Since both the lower sleeve and the upper sleeve are made of transparent heat - shrinkable tubes, the sealed connection sleeve can be naturally shrunk by acting on the outside of the sealed connection sleeve with a hot air gun to achieve natural sealing operation.

[0026] 2. At the bottom end of the lower sleeve in the present invention, a first sealing connection mechanism is fixed, and at the top end of the upper sleeve, a second sealing connection mechanism is fixed; the first sealing connection mechanism includes a flexible ring, a connecting rope loop and a connecting rope. The bottom end of the sealing connection sleeve is fixed on the flexible ring. A first airbag gasket is arranged near the top end inside the flexible ring, and a second airbag gasket is arranged near the bottom end inside the flexible ring. Inflation and deflation ports are fixedly communicated with both the first airbag gasket and the second airbag gasket inside the flexible ring. By adjusting the gas pressure in the first airbag gasket and the second airbag gasket, damage to the epidermis of the rootstock caused by excessive force of the connecting rope during use can be avoided. The second sealing connection mechanism includes an elastic ring, anti-slip strips and auxiliary tightening ropes. The elastic ring is fixed at the top end of the sealing connection sleeve, and anti-slip strips are arranged at both the top end and the bottom end inside the elastic ring. A plurality of auxiliary rings are adhesively attached to the outside of the elastic ring at equal intervals, and the auxiliary tightening ropes pass through the auxiliary rings in sequence. The elastic ring is tightened and sealed through the auxiliary tightening ropes.

[0027] 3. When the present invention is in use, the first sealing connection mechanism, the sealing connection sleeve and the second sealing connection mechanism are sequentially passed through the grape rootstock to be grafted, and then the second sealing connection mechanism is moved upward through the scion. During the upward movement, the positioning auxiliary line of the sealing connection sleeve is aligned with the alignment side of the rootstock and the scion. Under the action of an external force, the connecting rope is tightened, so that the first sealing connection mechanism is fixedly sealed and connected with the rootstock under the action of the connecting rope; then a hot air gun is used on the sealing connection sleeve, so that the sealing connection sleeve naturally shrinks and tightly adheres to and seals the outer surfaces of the rootstock and the scion, completing the sealing connection between the sealing connection sleeve and the rootstock and the scion. Finally, the auxiliary tightening ropes are tightened by an external force to tighten the second sealing connection mechanism, completing the sealing connection between the second sealing connection mechanism and the scion, and thus completing the sealing connection operation at the connection of the grape grafting and seedling raising, which is convenient and practical.

Detailed implementation mode

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] As Figures 1 - 3 shown, the present invention provides a technical solution: a sealed connector for grape grafting and seedling raising, including a sealed connection sleeve 1. The sealed connection sleeve 1 is composed of a lower sleeve 11 and an upper sleeve 12 that are fixedly connected and communicated with each other. The lower sleeve 11 and the upper sleeve 12 are both made of transparent heat-shrinkable tubes, and the inner diameter of the lower sleeve 11 is larger than the inner diameter of the upper sleeve 12;

[0035] During use, the lower sleeve 11 is sleeved outside the rootstock, and the upper sleeve 12 is sleeved outside the scion during use. Since both the lower sleeve 11 and the upper sleeve 12 are made of transparent heat-shrinkable tubes, the sealed connection sleeve 1 can be naturally shrunk by the action of a hot air gun on the outside of the sealed connection sleeve 1, achieving 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 is 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 line 13 is respectively nested inside the inner walls of the aligned sides of the lower sleeve 11 and the upper sleeve 12, and the positioning auxiliary line 13 is made of an elastic strip. The positioning auxiliary line 13 can naturally shrink and adjust during the heat shrinkage process of the lower sleeve 11 and the upper sleeve 12, improving the accuracy of the connection position during the use of the lower sleeve 11 and the upper sleeve 12.

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

[0038] The first sealed connection mechanism 2 includes a flexible ring 21, a connecting rope loop 24, and a connecting rope 25. The bottom end of the sealed connection sleeve 1 is fixed on the flexible ring 21. A first airbag gasket 22 is provided near the top end inside the flexible ring 21, and a second airbag gasket 23 is provided near the bottom end inside the flexible ring 21. Inflatable and deflatable ports are fixedly communicated with both the first airbag gasket 22 and the second airbag gasket 23 inside the flexible ring 21. The gas pressure in the first airbag gasket 22 and the second airbag gasket 23 can be adjusted respectively through the inflatable and deflatable ports, thereby avoiding damage to the epidermis of the rootstock caused by excessive force of the connecting rope 25 during use and improving the flexibility of the first sealed connection mechanism 2 during use.

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

[0040] The second sealing connection mechanism 3 includes an elastic ferrule 31, anti-slip strips 32 and an auxiliary tightening rope 34. The elastic ferrule 31 is fixed at the top end of the sealing connection sleeve 1, and anti-slip strips 32 are provided at both the inner top end and the inner bottom end of the elastic ferrule 31. A plurality of auxiliary rings 33 are adhesively attached at equal intervals outside the elastic ferrule 31. The auxiliary tightening rope 34 sequentially passes through the auxiliary rings 33, and the tightening and sealing operation of the elastic ferrule 31 is completed by the auxiliary tightening rope 34.

[0041] For convenient connection and use, the inner diameter of the flexible ferrule 21 is the same as the inner diameter of the lower sleeve 11, and the inner diameter of the elastic ferrule 31 in the natural state is the same as the inner diameter of the upper sleeve 12.

[0042] In order to facilitate the self-adjusting contraction of the distance between adjacent connecting rope loops 24 and auxiliary rings 33 during use, the connecting rope loops 24 are adhesively attached to the outside of the flexible ferrule 21 by glue, the auxiliary rings 33 are adhesively attached to the outside of the elastic ferrule 31 by glue, and the connecting rope loops 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-detachment blocks are provided at the ends of the connecting rope 25 and the auxiliary tightening rope 34. The outer diameter of the anti-detachment block at the end of the connecting rope 25 is larger than the inner diameter of the connecting rope loop 24, and the outer diameter of the anti-detachment block at the end of the auxiliary tightening rope 34 is larger than the inner diameter of the auxiliary ring 33.

[0044] For facilitating 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 usage method of the above-mentioned sealing connector for grape grafting and seedling raising includes the following steps:

[0046] S1. Before use, sequentially pass the first sealing connection mechanism 2, the sealing connection sleeve 1 and the second sealing connection mechanism 3 through the grape rootstock to be grafted. Then, perform pre-grafting treatment on the rootstock, that is, flattening and making a cut. Then, clamp the scion with the beveled surface processed on the top end of the processed rootstock, and align one side of the rootstock and the scion.

[0047] S2. Under the action of artificial external force, enlarge the aperture of the second sealing and connecting mechanism 3, and move the second sealing and connecting mechanism 3 upward through the scion. During the upward movement, align the positioning auxiliary line 13 of the sealing and connecting sleeve 1 with the aligned side of the rootstock and the scion. After the second sealing and connecting mechanism 3 drives the upper sleeve 12 to sleeve on the outside of the scion during the upward movement, stop;

[0048] S3. Then, under the action of external force, tighten the connecting rope 25 so that the first sealing and connecting mechanism 2 is hermetically and fixedly connected to the rootstock under the action of the connecting rope 25;

[0049] S4. Then, use a hot air gun on the sealing and connecting sleeve 1 so that the sealing and connecting sleeve 1 naturally shrinks and tightly adheres to and seals the outer surfaces of the rootstock and the scion, completing the sealing connection between the sealing and connecting sleeve 1 and the rootstock and the scion;

[0050] S5. Finally, use external force to tighten the auxiliary tightening rope 34 to tighten the second sealing and connecting mechanism 3, completing the sealing connection between the second sealing and connecting mechanism 3 and the scion, and thus completing the sealing connection operation at the joint of grape grafting and seedling raising.
