Description

  The present invention relates to a graft-holding tool, and in particular, to a graft-holding tool that holds a joint portion between a rootstock and a scion when grafting cucumber fruits such as cucumbers, watermelons, and melons.

  Traditionally, when cultivation of fruits and vegetables to be grown has been forced to grow during abnormal weather to avoid soil-borne diseases and some insect damage, to enable continuous cropping, or for year-round production The technique of grafting is used to change fruit traits and produce high-quality fruit vegetables by selecting rootstocks, for example, using cucumber bloomless rootstocks and pumpkins as rootstocks.

  For example, a watermelon uses a campy as a rootstock and grafts a watermelon head. Cucumbers mainly use pumpkins as rootstocks. For melon, eggplant, and tomato, different varieties are used.

  The applicant previously described in Patent Document 1, after grafting, until the seedlings are sufficiently grown, it can be supported by the support, the confirmation of the seedling insertion guide opening can be made easily, and the rootstock and the cuttings of cuttings are cut. A graft holder for eggplants (tomatoes, eggplants, peppers) having a structure that can reliably match the surfaces has been disclosed. This graft holder includes a plastic cylindrical body having a slit on one side from the upper end to the lower end, and a column mounting member having an arm curved in a state of closing the front of the slit near the upper end of the slit. A graft part holding tool, which is formed integrally with a knob part that can be pinched with a finger on the cylindrical body, and protrudes a semicircular scrub insertion guide whose inner surface is inclined at the upper end part of the cylindrical body, A semicircular rootstock insertion guide having an inclined inner surface is provided protruding from the lower end of the cylindrical body. Thereby, it became possible to match | combine the cut surface of a rootstock with the cut surface of a hogi easily, and the survival rate improved.

  Furthermore, even after the grafting is established, even if the seedling grows and becomes thicker than the diameter that the cylindrical body can hold, the seedling continues to be held inside the arm of the support mounting member. In the field of grafting of solanaceae, certain effects were seen in labor saving of grafting work and production of high quality grafted seedlings.

  There are eggplant families (eggplant, peppers, tomatoes, etc.) and cucurbitaceae (cucumbers, watermelons, melons, bitter gourds, etc.). When making a cucumber grafted seedling of the Cucurbitaceae, as shown in FIG. 8, the rooted pumpkin (root portion 103) is used for the rootstock 100. Of the two cotyledons 101, 102, one cotyledon 101 is left as shown in FIG. 9, and the other cotyledon 102 is cut obliquely upward with a cutter C or the like, and a piece with a cutting surface 104 shown in FIG. Let's say leaf rootstock 100. If one piece of leaf 101 is not left, the growth of the scion after grafting is poor and the survival rate is reduced.

  The graft holder disclosed in the above-mentioned Patent Document 1 is a graft holder suitable for the solanaceous family, and tomato, eggplant, bell pepper, etc. are diagonally left without leaving cotyledons in the seedlings as rootstocks as shown in FIG. A graft holder 20 shown in FIG. 12 is inserted into the rootstock 110 cut in the upward direction from top to bottom. Thereafter, as shown in FIG. 13, the grafting work can be performed by inserting the cut ears 120 into the rootstock 110 into which the grafting holder 20 has been inserted. However, in the case of producing grafted seedlings of the Cucurbitaceae, the graft graft holder 20 leaves one of the two cotyledons 101 and 102 of the seedling that becomes the rootstock 100 as shown in FIG. Must be fitted.

  Thus, in the case of the grafting work of the Cucurbitaceae, since one cotyledon 101 remains in the rootstock 100, as shown in FIG. 14, the cotyledon 101 gets in the way and moves the grafting fixture 20 downward from above. Cannot be inserted into. Therefore, the cutting surface 104 of the rootstock graft base 100 shown in FIG. 10 and the cutting surface 134 of the stem 133 of the stalk 133 shown in FIGS. Many small plastic pinches 30 using metal springs shown are used among grafting producers. The pinch 30 includes a C-shaped metal spring 31, a pair of sandwiching portions 32, and a knob portion 33 coupled by a thin hinge portion 34, and a conical pointed projection 35 on the inner surface of the sandwiching portion 32. Is formed. In addition, cotyledons 131 and 132 are attached to the hogi 130, and the lower end of the stem 133 is a cut surface 134 that is cut obliquely.

  Patent Document 3 discloses a cylindrical graft clip that uses the elasticity of soft plastic without using an iron or stainless spring. As shown in FIG. 21, the basic structure of the grafting clip includes a holding part 41 having a cylindrical shape with a predetermined length capable of enclosing the base part of the seedling for rootstock and the ear part of the seedling for hogi, and a holding part. 41 includes a slit 42 extending in the length direction of 41 and gripping portions 43 and 44 for slit opening and closing provided on the back surface of the holding portion 41. As shown in FIG. 22, the grips 43 and 44 provided on the opposite side of the slit 42 provided in the grafting clip 40 are picked to open the slit 42, leaving one cotyledon 101 as shown in FIG. It is sandwiched in the rootstock 100 from the lateral direction. Further, as shown in FIG. 24, the scrub 130 is inserted into the holding hole 45 (see FIG. 21), and the cut surface 134 (see FIG. 15) of the scrub 130 is the cut surface 104 of one leaf of the rootstock 100. Try to stick to it.

  Among the cylindrical holders with knobs, those described in Patent Document 2 have been commercialized and are used as cucurbitaceous graft holders.

  Further, in Patent Document 3, as shown in FIG. 25, a first connecting portion provided between the gripping portion 51 and the opening / closing portion 52 is provided with a pair of left and right rotating portions including a gripping portion 51 and an opening / closing portion 52. A grafting clip 50 is disclosed in which a pair of left and right rotating portions are connected by a second connecting portion 54 provided at the end portion of 53 and an opening / closing portion 52. A protruding line 55 is formed on the inner periphery of the grip 51.

  The above-described small plastic graft pinch 30 using the metal spring 31 shown in FIGS. 17 and 18 requires assembly because it uses the plastic clamping piece 32 and the metal spring 31, and the cost is high. The weight increases, so it costs the seedlings.

  Further, in the grafting pinch 30, many thin hinge portions 34 are broken by a single grafting seedling production operation, and many of them cannot be reused.

  When the clip is reused and grafted, it is used after washing and disinfecting, but the graft pinch 30 using the metal spring 31 closes the spring even when nothing is sandwiched as shown in FIG. Since the tip 36 is pressed and adhered by the force, it is necessary to pick and hold the knobs 33 one by one, open the tip 36 of the clamping part 32, and perform cleaning and disinfection.

  When producing grafted seedlings of cucurbitaceae (cucumbers, etc.) during busy periods, demand is concentrated at one time, so there are many nurseries who hire part-time workers and produce grafted seedlings.

  The above described grafting pinch 30 using the metal spring 31 shown in FIG. 17 includes the cut surface 104 (see FIG. 10) of the cut rootstock 100 and the cut surface 134 (see FIGS. 15 and 16) of the scrub 130. (See Fig. 19), so that the knob 33 of the grafting pinch 30 is pinched and pinched with the other hand (see Fig. 19) with the fingertips of the other hand facing each other and keeping them from shifting. It is difficult to cut and graft the cut surfaces 104 and 134 of the rootstock 100 and the hogi 130 so as not to shift.

  In the grafting clip 40 shown in FIG. 21, since the thickness of the stems of the rootstock and the hogi varies, the size of the holding hole 45 corresponding to the thickness of the seedling is necessary, and the diameter is about 2 mm, There are about three millimeters, around 3 mm and around 4 mm, and they must be used properly.

  In the grafting pinch 50 shown in FIG. 25, when the operator grafts by hand, the cutting surfaces 104 and 134 of the rootstock 100 and the scrub 130 are aligned with one hand as in the conventional case shown in FIG. It must be picked and the grafting pinch 50 must be fastened to the stem with the other hand. In addition, since it is a polyethylene material, it can be made only translucent, so it is difficult to check the displacement of the joint.

  Therefore, the present invention does not require a metal spring for giving a gripping force, and is not easily broken like a thin hinge part of a small plastic grafting pinch using a conventional metal spring. An object of the present invention is to provide a grafting tool that can cope with the size of the diameter of a stem of a tree or a hogi and can easily check the joint of the graft by visual inspection.

  In order to solve the above-mentioned problems, the graft-holding tool according to the present invention is arranged with a space between the stem holding portions and a pair of holding portions in which the space at the tip is open when not in use, and the pair of holding devices Each of the pair of gripping portions and a U-shaped connecting portion for connecting the base end portions of the pair of gripping portions to each other, and the inner surfaces of the pair of holding portions facing each other. In addition, a plurality of protrusions are provided so as to be entirely made of a single soft plastic.

  In the present invention, since it is a single-piece grafting tool using an elastic force without using a metal spring, it is light in weight and low in production cost. Moreover, since the hinge part which connects a pair of clamping parts is not made thin, it does not break when using a graft.

  In the graft-holding tool of the present invention, the space on the connecting part side in the stem holding part is wider than the space on the tip part side, the space on the tip part side is gradually narrowed, and the stem holding part is expanded, Since the stem can be pinched in the back of the stem holding part and the thick stem can be held at the part close to the tip, the grafting work of the cucurbitaceae can be done with one kind of grafting tool.

  In the graft graft gripping tool of the present invention, the interval between adjacent ridges of the plurality of ridges is approximately the same as the diameter of the stalks to be gripped. The stem of the cucumber panicle is about 1.5 mm, for example. By setting the interval between the ridges to that extent, even if it is not a skilled worker, the stalk is sandwiched from the top after sandwiching the rootstock. Since it can be inserted along the gap between them and the cut surfaces of the rootstock and the hogi are aligned without shifting, the grafting work can be performed, so even beginners can perform grafting work without failure.

  The soft plastic that is the material of the graft-holding tool of the present invention is a transparent and crystalline resin. A crystalline resin is a resin that has the property of returning to its original shape when warmed even after deformation as it is used as a product. The grafting tool once used for grafting sandwiches the growing stalk for a long time and gradually opens during that time. If it does so, the pinch hook by an elastic force will be attached, and it will collect | recover and it will not be suitable for reuse. Therefore, after collecting, cleaning, disinfecting a large number of collected grafting tools, it is possible to reuse them by soaking them in hot water and removing the pinch so that the tip of the original gripping part becomes narrower. Will also be easier.

  Moreover, since it is made of transparent soft plastic, it is possible to easily confirm the state of the joint between the cutting surfaces of the rootstock and the hogi.

  According to the present invention, a pair of sandwiching portions that are arranged apart from each other by a space between the stem holding portions and open at the distal end when not in use are connected to the base end side of the pair of sandwiching portions, respectively. And a plurality of ridges projecting on the opposing inner surfaces of the pair of sandwiching portions, and a U-shaped connecting portion that connects the base ends of the pair of gripping portions. A grafting tool that is entirely made of soft plastic, the space on the connecting part side of the stem holding part is wider than the space on the tip part side, and the space on the tip part side is gradually becoming narrower, It is made of metal to give a gripping force because the spacing between adjacent ridges of the plurality of ridges is about the same as the diameter of the stalks to be gripped, and the material is transparent and crystalline resin Springs are not required, and a small plastic graft pinch using conventional metal springs Fragile that no such hinge portion of meat, can respond in one of the size of the diameter of the stem of a stock and scion, further an effect that visual confirmation of the junction of the grafting is easy.

FIG. 1 is a perspective view showing a configuration of a grafting tool 10 according to an embodiment of the present invention.
The grafting tool 10 includes a pair of holding parts 1 and 2, a connecting part 3 that connects the bases of both holding parts 1 and 2, and a knob that opens and closes the holding parts 1 and 2 with the connecting part 3 as a hinge part The tip portion 6b is narrower than the back portion 6a of the stem holding portion 6 between the sandwiching portions 1 and 2, but the tip portion 6b does not stick. Three ridges 1a and 2a are provided on the inner side of both clamping parts 1 and 2, respectively. Outside the knob portions 4 and 5, finger slip prevention portions 4 a and 5 a when pressing the knob portions 4 and 5 are provided. The grafting tool 10 is made of a transparent soft plastic made of crystalline resin and is integrally formed, and has a gripping force due to the elastic force of the soft plastic itself. The ridges 1a and 2a inside the stem holding part 6 are provided at intervals of about 1.5 mm which are almost the same as the diameter of the stem of the cucumber panicle, and after inserting the rootstock when the cucumber panicle is inserted, The cutting surface of the cotyledons can be inserted without shifting the cutting surface of the hogi.

  In the grafting operation using the grafting tool 10 of the present embodiment, the skilled person uses a conventional method familiar to the cutting surface 104 of the cotyledon 102 of the pumpkin rootstock 100 shown in FIG. The grafting surface shown in Fig. 1 is obtained by aligning the stem cutting surface 134 of the scrub 130 with the fingertip of one hand and pinching and pinching the knob portions 4 and 5 of the grafting gripping tool 10 with the other hand while keeping the cutting surfaces 104 and 134 from shifting. The method is used (see FIG. 4).

  In a part-time job unfamiliar with the grafting work, a single leaf is attached to the side of the stem holding part 6 of the graft holding tool 10 to the root pumpkin rootstock 100 cut as shown in FIG. 5 so as to facilitate the grafting work. The cut surface 104 is sandwiched. After sandwiching the rootstock 100, the hogi 130 is inserted from the top to the bottom as shown in FIG. Since the protrusions 1a and 2a are present when the hotwood 130 is inserted, the hotwood 130 enters the lower direction without being laterally displaced, so that the cotyledons of the rootstock 100 sandwiched between the holding portions 1 and 2 of the grafting handle 10 Since the cut surface 104 and the cut surface 134 of the scrub 130 can be aligned without shifting, a grafting operation with a high survival rate can be performed with a part-time job.

  As shown in FIG. 7, the root root 103 of the stem of the rootstock 100 is obtained by sandwiching the cotyledon cutting surface 104 of the rootstock 100 and the cutting surface 134 of the stem of the earwood 130 with the graft holding tool 10 so as not to shift. Is inserted into the medium, a new root is rooted at the root portion 103, and a grafted seedling can be formed.

  The graft-holding tool 10 once used for grafting sandwiches the joint of the grafted seedlings for about 12 days, grows and grows thick, and is pinched using elastic force, so that it has a pinch. Then, when the grafting tool 10 is reused, the tip of the stem holding part 6 that sandwiches the cut surfaces 104 and 134 of the rootstock 100 and the scrub 130 is open due to the pinch, so that the gripping force remains as it is. Is weak. Therefore, a large number of graft graft holding tools 10 are put together and washed and sterilized.

  Since this product is integrally molded with a crystalline resin, after being washed and disinfected, it is immersed in hot water at around 60 ° C for 2 to 3 minutes, so that it is about 0.7 mm, which is the same as the gap at the tip of the clip before using the graft. , So that it can be easily reused.

  Moreover, since the graft-holding tool 10 of this embodiment does not have the thin hinge 34 as shown in FIGS. 17 and 18 at the center of the sandwiching portion, it does not break when the graft is used.

  The cylindrical graft graft clip 40 shown in FIG. 21 requires a holding hole size according to the thickness of the rootstock 100 and the shrub 130 to be grafted, but the graft graft holding tool 10 has a stem as shown in FIG. Since the holding part 6 has a different distance between the back and the tip, a small stem can be sandwiched between the stem holding part back 6a, and a thick stem can be held at the tip 6b. The gripping tool 10 can be used. Further, since it is made of a transparent soft plastic, it is possible to easily confirm the state of the joint between the cutting surfaces 104 and 134 of the rootstock 100 and the hogi 130.

  25. The protrusions 55 having a width of 0.5 mm or less are provided on the gripping surface of the conventional grafting pinch or the grafting pinch 50 in FIG. 25, but no gap is provided at intervals of the thickness of the cucumber seedling stems. Instead, it simply grips the grafted seedling to make it difficult to dislodge the rootstock and the seedling, and it has no role or effect as a slip prevention guide when inserting the cucumber seedling into the grafted gripping tool.

  The graft pinch 30 shown in FIG. 17 is provided with a conical pointed projection 35 so that the joint portion of the rootstock and the spikelet is pierced shallowly and held in the holding part of the seedling so as not to shift. After attaching the rootstock, you can't insert Hogi downward from the top.

  There is no need for a metal spring to give gripping force, and it is not easily broken like the thin hinge of a small plastic grafting pinch using a conventional metal spring. One can handle the size of the stem diameter, and it can be suitably used as a grafting tool for grafting, in which the joint of the grafting can be easily confirmed by visual observation, particularly for grafting of the cucurbitaceae family.
