Double grafting method

The invention relates to a grafting method, in particular to a double grafting method of plugging.

The grafting technique is widely used in the reproduction of melons. The procedure is to transplant the two plantlets into a grafting part, and then cut a grafting part on the main stem of the rootstock to connect the scion seedlings obtained by the other seedlings to the grafting part. Then the two strains grow together and work together. This way, excellent seedlings can be propagated and grow well. Plants that are grafted and propagated usually have the same properties as the rootstocks or cotyledons, and have a higher success rate of reproduction.

According to the conventional grafting method, when the cotyledon expansion is performed, it is often because the cotyledonary node is too small, the hypocotyl is too thin, and then the top end of the hypocotyl is applied as a grafting hole, which is not only difficult to operate, but also causes the cotyledonary node and embryo. When the shaft is split, the rootstock cannot be grafted effectively. Therefore, when the grafted seedling field is grafted by the plugging method, it will wait until the first leaf of the rootstock is unfolded, the factor leaf section is larger and the hypocotyl is thicker. Therefore, the application of the grafting hole and the insertion of the scion can be facilitated; however, the first piece of the leaf insertion method described above needs to wait at least five days, which not only increases the cost of the rootstock planting, but also increases the production cost, and because of the cotyledonary section Larger, hypocotyl large to form a hollow medullary cavity, 俾 easy to grow when the roots of the stalk grow, produce adventitious roots and extend into the soil along the medullary cavity to infect soil-borne diseases, thereby reducing the survival probability and growth life of the scion, lack of economy Benefits.

In addition, the market has a double grafting method, the holder must be used to hold the rootstock and the joint of the scion, because some of the melon stems are very small, such as melon tissue culture seedlings, easy to be clamped after clamping The compression of the pieces causes the scion to be damaged by pinching, resulting in the scion not being able to survive, and there is no breeding efficiency.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

The technical problem to be solved by the present invention is to provide a double grafting method for plugging in view of the above-mentioned shortcomings existing in the prior art.

A double grafting method for plugging, comprising the following steps: planting a rootstock: planting two melons as a rootstock; obtaining a scion: a melon obtained to obtain a melon with at least a certain bud or a leaf Or the stem as the scion; the rootstock is taken as follows: after the two rootstocks are unfolded in the two cotyledons, one of the rootstocks and one of the cotyledons and the hypocotyls can be cut so that one of the rootstocks has all the faces after cutting, and then the two rootstocks are combined. Relying and being clamped and fixed by a grafting clip, the crucible can be perforated to form a grafting hole, and the grafting hole is deep into the hypocotyl of another rootstock; scion cutting: cutting the hypocotyl or stem of the scion Inserting the hypocotyl or stem with at least one grafting cut surface; performing the plugging: inserting the plug portion of the scion into the grafting hole of the cutting surface of the rootstock, and allowing the plugging portion to deeply contact another rootstock along the grafting hole, thereby further The scion and the two rootstocks are connected to each other, so that the grafted cutting surface of the plugging portion can be in contact with the grafting hole surface of the two rootstocks, thereby completing the grafting process.

Compared with the efficacy of the prior art: (1), the grafting method of the present invention is based on two rootstocks The grafting step begins at the expansion stage of the cotyledon, which not only reduces the growth days of the rootstock, reduces the cost during the growth of the rootstock, but also shortens the time for the grafting process of the farmers, which not only greatly reduces the cost, but also improves the economic benefit.

(2) The second rootstock is processed by the facet to form the grafting hole, so that the hypocotyl of the rootstock is not cracked when applied as a grafting hole, and the rootstock after cutting can greatly reduce the wall thickness, when the scion is cut and In the plugging step, not only the cutting length of the scion on the grafted cutting surface can be shortened, but also the insertion portion of the fine scion is cut too thin or too soft during the cutting process, and cannot be inserted into the grafting hole of the second rootstock, but is more conducive to the fine scion Cutting, thereby simplifying the cutting step of the scion insertion portion, so that the plug portion 11 of the scion can be surely inserted between the two rootstocks, and the grafting cut surface is in close contact with the grafting holes of the two rootstocks, thereby improving the healing density of the scion and the two rootstocks and The absorption efficiency of nutrients.

(3) The grafting clip is mainly used for the clamping and fixing of the two rootstocks, and the scion is also inserted between the two rootstocks through the plugging, so that the joint between the scion and the rootstock does not need to be clamped and fixed through the clamping unit, so It is necessary to avoid the damage of the fine scion by the grafting clip, ensure the success rate of the grafting and the survival rate, and improve the efficiency of the scion production.

In order to enable your review committee to have a better understanding and understanding of the purpose, features and effects of the present invention, please refer to the following [simplified description of the drawings] as follows: First, please refer to Figure 1 with the second to sixth As shown in the figure, a double grafting method of plugging is to use a hypocotyl or stem having at least a certain bud or a leaf as a scion 10, and grafting on two melons with good affinity. The rootstock 20 is under the hypocotyl, and the grafting method comprises the following steps: rootstock planting: planting two melons as rootstocks 20; obtaining scion: the melon to be obtained, at least A hypocotyl or stem of a certain bud or a leaf is used as the scion 10; the rootstock is connected: after the two rootstocks 20 are unfolded in the dicotyledon 21, one of the rootstocks 20 and one of the cotyledons 21 and the hypocotyls can be cut, such that one of them After the rootstock 20 is cut, it has all the faces 2, and then the two rootstocks 20 are placed together, and are clamped and fixed by a grafting clip 23. The puncture can be arranged for the cut surface 22 to form a grafting hole 221, and the grafting hole 221 is low. On another The cotyledonary node above the hypocotyl of the wood further penetrates the grafting hole 221 into the hypocotyl of another rootstock 20; scion cutting: cutting the hypocotyl or stem of the scion 10 such that the hypocotyl or stem has at least one grafting section 111 Inserting portion 11; inserting: inserting the plug portion 11 of the scion 10 into the grafting hole 221 of the cut surface 22 of the rootstock 20, and inserting the plug portion 11 into the other rootstock 20 along the grafting hole 221, thereby further attaching the scion 10 and two rootstocks 20 The connection is made, and the grafting surface 111 of the plugging portion 11 can be in surface contact with the grafting holes 221 of the two rootstocks 20, thereby completing the grafting process.

Furthermore, when the rootstock is connected, the rootstock 20 can be cut when the leaf has not been unfolded, and the grafting hole 221 is configured on the cutting surface 22 for the insertion of the scion 10, however, the root of the rootstock 20 has not yet been When it is unfolded, the medullary cavity formed by the hypocotyl of the rootstock 20 is relatively small, so that the splicing portion 11 is inserted into the grafting hole 221 between the two rootstocks 20, and the insertion portion 11 can be greatly improved. The contact area between the grafted cutting surface 111 and the inner wall of the grafting hole 221 of the rootstock 20 improves the integrity of the grafting of the rootstock 20 and the scion 10, and on the other hand allows the grafting section 111 of the plugging portion 11 to closely fit the grafting hole 221 To avoid the emergence of adventitious roots in the scion 10, to prevent the roots of the scion 10 from spreading along the medullary cavity into the soil, and to improve the survival rate and growth life of the scion 10, thereby reducing the production cost of farmers.

In addition, when the rootstock is connected, one of the other leaves 20 of the rootstock 20 can also be cut off. Please also refer to FIG. 7 so that the two rootstocks 20 only have the cotyledons 21 in the same direction, when the rootstock 20 is used as a grafting hole. When the scion 10 is inserted, the convenience of inserting the scion 10 can be avoided, and the attachment of the scion 10 can be improved, and the scion 10 can be prevented from being blocked by the cotyledon 21, thereby improving the growth efficiency.

Moreover, when the rootstock is connected, the grafting clip 23 is placed on the cut surface 22 of the two rootstocks 20, so that the two rootstocks 20 can be more closely adhered to the cut surface 22, so as to facilitate the insertion of the grafting holes 221, and at the same time enhance the grafting. For the tightness of the hole 221, please refer to the figures 8 and 9 at the same time, and the grafting clip 23 has a hollow shape, and the dodging grafting hole 221 is provided to facilitate the plugging step of the scion 10.

By the structure of the above specific embodiment, the following benefits can be obtained: (1) The grafting method of the present invention begins the grafting step during the development of the cotyledon 21 of the second rootstock 20, which not only reduces the growth days of the rootstock 20, but also reduces the rootstock. 20 spending during the growth period, can also shorten the farmers' grafting steps In a short period of time, not only can the cost be significantly reduced, but the economic benefits will be improved.

(2) The second rootstock 20 is formed by the cutting surface 22 to form the grafting hole 221, so that the hypocotyl of the rootstock 20 is not cracked when applied as a grafting hole 221, and the rootstock 20 after cutting can greatly reduce the wall thickness. When the cutting and inserting steps of the scion 10 are performed, not only the cutting length of the scion 10 on the graft cutting surface 111 can be shortened, but also the insertion portion 11 of the small scion 10 is cut too thin or too soft during the cutting process, and the two rootstocks cannot be inserted. In the grafting hole 221 of 20, the cutting of the small scion is more favorable, thereby simplifying the cutting step of the plug 10 of the scion 10, so that the plug portion 11 of the scion 10 can be surely inserted between the two rootstocks 20, and the grafting surface 111 is The grafting holes 221 of the second rootstock 20 are in close contact, and the healing density of the scion 10 and the two rootstocks 20 and the absorption efficiency of the nutrients are improved.

(3) The grafting clip 23 is mainly used for the clamping and fixing of the two rootstocks 20, and the scion 10 is also inserted through the two rootstocks 20 so that the joint between the scion 10 and the rootstock 20 does not need to pass through the clamping unit. The clamping is fixed, so that the fine scion 10 is prevented from being damaged by the grafting clip 23, the success rate of the grafting of the scion 10 and the survival rate are ensured, and the production efficiency of the scion 10 is improved.
