Description

{Cutting and grafting method of apple tree}

The present invention relates to a method of grafting an apple tree.

In order to produce apple seedlings, grafting is essential, but grafting requires a high level of proficiency, so it is not easy to nurture manpower and the supply and demand of manpower is not smooth due to the aging of existing grafting experts. Moreover, in the case of apples, the demand for grafting is concentrated in the spring, making this difficult. Among the seedlings sold in Korea, the proportion of the seedlings produced using the roots of the roots is continuously increasing.

In Patent Document 1, since it is produced by grafting varieties after planting trees that have been breeding with a burrow, it takes at least two years. there is a problem.

Patent Document 2 discloses a method of producing seedlings by directly harvesting and grafting and rooting trees. This method can shorten the overall production time of seedlings compared to the method of Patent Document 1, but there is no consideration of productivity according to the grafting site and productivity according to rooting conditions.

In this process, the thickness of the lines or the size of components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or practice. Therefore, the definition of these terms should be described based on the contents throughout this specification.

In addition, the described embodiments are provided for illustrative purposes only, and do not limit the technical scope of the present invention.

Hereinafter, a method of grafting an apple tree according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 7.

1 is a flowchart illustrating a procedure of an apple tree grafting method according to an embodiment of the present invention.

As shown in Figure 1, in the method of grafting an apple tree according to an embodiment of the present invention, (a) cutting the grafted portion of the harvested shovel into a V-shape, grafting the reception to the cut grafting portion, Forming; (b) raising the base of the tree; (c) immersing the raised base of the tree in a rooting agent and a fungicide; (d) preparing a shoveling box filled with shoveling soil mixed with vermiculite and loam; (E) step of inserting the timber, which has been immersed in the base, into the prepared shoveling box; (f) rooting the large tree by maintaining the predetermined temperature for a predetermined period of time in the shoveling box where the shoveling is completed; And (g) sealing and storing the shovel box in which the predetermined period has elapsed.

First, the grafted portion 30 of the collected shovel 10 is cut into a V-shape, and grafted with the receiving 20 to the cut grafted portion 30 to form a large tree 40 (S10).

The shovel 10 is collected from the parameters of the tree 40 to be formed. The parameters can be collected from the dormant branch of a 1-year-old apple tree. The type of the parameter is not limited, but can be selected as a dwarf (M26) or an extreme exogenous (M9) with good dwarfability.

As shown in Fig. 2, it is preferable to cut the dormant of the parameter to a length of about 30 cm or so and collect it.

The grafting portion 30 (the upper end) of the shovel 10 collected by cutting is cut into a V shape, and the grafting portion 30 of the receiving 20 is inserted into the V-shaped grafting portion 30 of the shovel 10. Cut into wedges as possible.

2 and 3, after grafting the cut portion of the receiving 20 and the cut portion of the shovel 10, grafting the circumference of the grafted portion with a grafting tape or the like to bind the block 40. To form.

Conventionally, in the formation of the grafting part 30, a lot of clippers are used, but on average, 2,500 grafts per day are available for 2 people (grafting specialists and assistants).

On the other hand, in the V-type grafting of the present embodiment, 4,000 grafting can be performed by 3 persons per day, and the grafting time can be shortened to 7.2 seconds / piece, compared to 11.5 seconds / piece of the clip-type grafting. , Even unskilled people can easily graft.

Next, the base of the formed timber 40 is raised (S20).

As shown in FIG. 4, the base (lower part) of the large tree 40 in which the shovel 10 and the receiving 20 are grafted is raised.

Such a raise process is performed by peeling off the epidermis of the base 40 of the base 40 (for example, three places). In the past, there was a case in which rooting was performed in a state in which the entire base was cut, but uniform rooting may not be achieved, and by peeling off the epidermis of the base 40 base as described above, uniformity in the base 40 base Rooting in one state can be achieved.

Next, the base of the raised tree 40 is immersed in a rooting agent and a fungicide (S30).

The base of the tree 40 is made through a pre-made rooting agent and a fungicide.

The base is treated by sequentially immersing the raised base in the rooting agent and the disinfecting agent.

The rooting agent is prepared by diluting the rooting accelerator in water, and the rooting accelerator is not limited, but it may be preferable to use a hormone, for example, a β-indolebutyric acid (IBA) solution, and the IBA solution to distilled water. It can be used after being diluted to a concentration of 2000ppm.

The sterilizing agent is not limited, and a known sterilizing agent for grafting may be used. For example, hexaconazole may be diluted with distilled water at a concentration of 50%.

After the base is immersed in the rooting agent for a certain period of time, again after a certain period of time, it is again immersed in the disinfectant.

Next, the shovel box 50 is prepared (S40).

Prepare a shoveling box 50 to insert the lumber 40 which has been immersed. As shown in FIG. 4, the shoveling box 50 is prepared and filled in the shoveling box 50 to prepare the shoveling box 50.

The shovel lodge 55 is composed of a mixture of vermiculite and loam, but there is a difference in the rate of seedlings obtained later depending on the mixing ratio of vermiculite and loam. Table 1 below shows the difference in the seedling acquisition rate according to the mixing ratio of vermiculite and loam.

Shoveling period (days) Mixing ratio of shoveling soil
(Vermiculite: loam) Seedling acquisition rate (%) Myogo (cm) Logistics (pcs) Root length (cm) 25 1: 1 2 58 15.0 13.4 2: 1 24 19 4.6 8.6 4: 1 10 16 3.8 13.7 8: 1 2 - 1.0 13.0 45 1: 1 2 66 8.0 6.3 2: 1 14 16 2.1 6.3 4: 1 6 32 2.7 4.2 8: 1 0 - - -

As shown in Table 1 above, it can be seen that the highest rate of seedling acquisition is to create the shoveling lodge 55 at a mixing ratio of vermiculite and loam. Next, the dipping 40 with the immersion of the base is completed. The prepared shoveling box 50 is shoveled (S50).

In the shoveling box 50 filled with the shoveling soil 55 formed as described above, shoveling 40 is immersed in rooting agent and fungicide.

As shown in FIG. 5, it is preferable that the lower portion of the large tree 40 is inserted into the shoveling soil 55 in the shoveling box 50 to a depth of about 20 cm.

Next, the shoveling box 50 in which the shoveling is completed is maintained at a predetermined temperature for a predetermined period to root the tree 40 (S60).

When the shoveling of the shovel 40 in the shovel box 50 is completed, the shovel box 50 in which the shovel 40 is inserted is maintained at a set temperature for a certain period (about 25 days).

It is preferable to maintain the set temperature at about 25 ± 3 ° C, and additionally, the set temperature can be easily maintained by placing the shovel box 50 on the heat transfer bed.

As shown in FIG. 6, the large tree 40 maintained at a set temperature for a certain period in the shovel box 50 becomes a seedling that can be transplanted and grown by rooting at the raised base (see FIG. 7).

Thereafter, the shovel box 50 after a certain period of time is sealed and stored (S70).

As described above, it is maintained at a set temperature for a period of time, and when rooting of the inserted timber 40 is made, the shoveling box 50 is sealed and stored at a low temperature. As a result, further growth can be reduced before shipment of seedlings with rooting.

As such, the stored seedlings are shipped and transplanted at the time of transplantation (approximately late March), so that they can be grown.

As described above, according to the method of grafting an apple tree according to the present invention, it is possible to increase the productivity of a tree by cutting and grafting one dormant tree to an appropriate length, thereby grafting the produced tree and grafting the produced tree. When seedlings are produced by rooting, they have the advantage of being able to increase temporal and spatial efficiency compared to conventional methods.

Specifically, compared to the existing method of producing apple seedlings, the time was reduced by 50% (2 years → 1 year) and the productivity increased by 300% (1 plant per 1 plant of grass plant → approximately 3 plants). However, the labor force for the production of large-scale timber as in the conventional buried method becomes unnecessary.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. That is, a person having ordinary knowledge in the technical field to which the present invention pertains can make a number of changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications Equivalents should also be considered within the scope of the present invention.
