Description

Technical Field

[0001] The present disclosure relates to a grape cultivation system.

Background Art

[0002] In grape cultivation, it is common to train the main branches that grow for each vine along a guiding member such as a wire to form and maintain a certain tree shape. In the field, a cultivation method is widely practiced in which a plurality of vines are arranged in a row along a predetermined direction, and a guiding member is provided along the row.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In conventional general row cultivation, only one guiding member is provided for each row, and a configuration is adopted in which the main branches possessed by each vine belonging to the row are trained along the common guiding member. In such a configuration, since the main branches possessed by adjacent vines inevitably pass through the same line or positions that are extremely close to each other, there is a risk that the main branches will interfere with each other. In order to avoid this, if each main branch has to be pruned short, the number of fruiting mother branches that can be secured per vine is limited, and the production capacity of each individual vine cannot be fully utilized.

[0004] On the other hand, by widening the inter-vine spacing within the same row, it is possible to extend the main branches longer while avoiding interference between the main branches. However, this method has a dilemma in that the number of plants per cultivation area decreases, leading to a decrease in the utilization efficiency (profitability) of the entire field.

[0005] Such problems are common problems in high-density cultivation aimed at obtaining the maximum harvest from a limited cultivation space, regardless of whether it is field cultivation or root-restricted cultivation (pot cultivation). In particular, in root-restricted cultivation using pots, while the tree vigor can be controlled by restricting the spread of the roots and it is possible to physically pack the plants closer together, the congestion of branches in the above-ground part is more likely to become a significant bottleneck.

[0006] This disclosure is made to solve these problems and aims to provide a grape cultivation system that can maintain a high planting density while allowing the main branches of individual grapevines to grow sufficiently. [Means for solving the problem]

[0007] A grape cultivation system in one aspect of the present disclosure comprises a plurality of grape plants arranged in rows along a predetermined first direction, a plurality of linear or rod-shaped training members extending in the first direction and provided in each row, and a plurality of supports for the plurality of training members, wherein the plurality of training members are arranged in each row to pass through different positions in a second direction which is a horizontal direction perpendicular to the first direction, and the first and second main branches of each plant that extend along the first direction are trained along one of the plurality of training members provided in the row in which the plant is arranged, wherein for adjacent plants in a row, the training members to which the first and second main branches of one plant are trained are different from the training members to which the first and second main branches of the other plant are trained. [Effects of the Invention]

[0008] According to this disclosure, it is possible to provide a grape cultivation system that can maintain a high planting density while allowing the main branches of individual vines to grow sufficiently. [Brief explanation of the drawing]

[0009] [Figure 1] This is a schematic plan view illustrating a grape cultivation system according to the first embodiment. [Figure 2] Figure 1 is a perspective view showing one row in the grape cultivation system. [Figure 3] This is a top view of a conventional grape cultivation system related to a comparative example. [Figure 4] This is a schematic plan view illustrating a grape cultivation system according to a second embodiment. [Modes for carrying out the invention]

[0010] Before describing the details of this disclosure, an overview will be provided. The embodiments of this disclosure relate to a grape cultivation system. The basic idea of ​​the grape cultivation system is to provide multiple training members for each row of plants arranged in rows, thereby training the main branches of adjacent plants to pass through different positions in the horizontal direction perpendicular to the direction of extension of the row. By providing multiple training members in this way, it is possible to avoid having the main branches of adjacent plants pass through the same position and to train each main branch to pass through different positions. As a result, it is possible to extend each main branch to a sufficient length while maintaining a high planting density, and to increase the number of fruiting branches that can be secured per plant.

[0011] Furthermore, the configuration in which plants are classified into multiple groups according to prescribed rules and the main branches are guided to the training members corresponding to each group is one way of embodying the above basic concept, and this disclosure is not limited to whether or not such grouping is performed or to specific classification methods. In addition, this disclosure is not limited to specific tree shapes or pruning methods, but is a technical concept that can be appropriately applied according to field conditions, variety characteristics, and cultivation purposes.

[0012] The present disclosure will be described below with reference to the drawings, based on preferred embodiments. In embodiments and modifications, the same or equivalent components and members are denoted by the same reference numerals, and redundant descriptions are omitted as appropriate. The dimensions of the members in each drawing are enlarged or reduced as appropriate for ease of understanding. In addition, some members that are not important for explaining the embodiments are omitted in each drawing.

[0013] (First Embodiment) Figure 1 is a schematic plan view showing a grape cultivation system 1 according to the first embodiment. In Figure 1, since the configuration is shown as a schematic diagram, the support posts 50 and training members 60 are shown with dashed lines to make them easier to distinguish from other components. Figure 2 is a perspective view showing one row in the grape cultivation system 1 of Figure 1. In Figure 2, the support posts 50 are not shown.

[0014] This embodiment is a specific example where the number of support members provided in each row is two, that is, the number of support members N is 2, and is the most concise embodiment of the basic concept of this disclosure. For the sake of explanation, the following description will describe a configuration employing so-called root-zone restricted cultivation, in which each plant is planted in a pot that restricts the spread of roots, as an example, but this disclosure is not limited to this.

[0015] The grape cultivation system 1 according to this embodiment comprises a plurality of grape plants 10 arranged in rows along a predetermined X direction (first direction), a plurality of linear or rod-shaped training members 60 extending in the X direction and provided in each row, and a plurality of support posts 50 supporting the plurality of training members 60.

[0016] Multiple grape plants 10 are arranged in rows along the X direction. In this embodiment, as described above, as an example, root-restricted cultivation is employed in which each plant 10 is planted in a pot (cultivation container) 20 that restricts the spread of roots. For this reason, in each row, multiple pots 20 are also arranged in rows along the X direction.

[0017] Each plant 10 does not necessarily have to be arranged in a strictly straight line in the X direction; it may be positioned slightly offset from a hypothetical alignment line relative to the reference X direction in the Y direction (a second direction), which is a horizontal direction perpendicular to the X direction. Furthermore, a configuration in which the entire row is arranged in a gentle curve is also included in the term "row-like" in this disclosure. In the illustrated example, a configuration in which multiple rows are arranged in parallel is shown, in which case the space between adjacent rows functions as a passage 70 for workers to move between. The main branches 42, which are supported and guided along the guiding members 60 provided in each row, are positioned to pass above the passage, thereby ensuring space for the passage 70.

[0018] In this embodiment, in each row, a plurality of training members 60 are arranged in the Y direction at a distance from each other, with a first training member 60_1 and a second training member 60_2 extending in the X direction. These two training members 60 are supported by a plurality of support posts 50 arranged at predetermined intervals along the X direction. The training members 60 are elongated members capable of supporting and training the main branches 42 of the grape vine 10, and their material is not limited. For example, the training members 60 can be linear members such as metal wire, stainless steel rope, or resin-coated wire, or rod-shaped members such as metal pipes, resin poles, bamboo, or wooden rods.

[0019] The first guiding member 60_1 and the second guiding member 60_2 extend in the X direction as described above and are arranged substantially parallel to each other. However, this disclosure is not limited to this configuration, and the scope of this disclosure also includes cases where both guiding members do not extend perfectly along the X direction due to installation errors or the influence of field shape, or where they are arranged non-parallel to each other at a slight angle, or where the spacing between them varies depending on the location.

[0020] Furthermore, the guiding member 60 does not need to extend in a strictly straight line; it is sufficient if it extends substantially along the X direction, even if it is bent or curved depending on the installation position of the support column 50.

[0021] Furthermore, the installation heights of the first attracting member 60_1 and the second attracting member 60_2 may be the same, or they may be intentionally displaced in the vertical direction.

[0022] Each stock 10 planted in each pot 20 has a first main branch 42_1 and a second main branch 42_2 (when not particularly distinguished or grouped together, referred to as "main branch 42"). These main branches 42 are supported and attracted along the attracting member 60 provided in the row with the tree trunk 40 as the base point, and extend in opposite directions along the X direction.

[0023] In the present embodiment, in each row, a plurality of stocks 10 arranged along the X direction are classified into odd-numbered stocks and even-numbered stocks based on their arrangement order. Hereinafter, the group to which the odd-numbered stocks belong is referred to as the first group, and the stocks belonging to the first group are also denoted as stocks 10_1 of the first group. Also, the group to which the even-numbered stocks belong is referred to as the second group, and the stocks belonging to the second group are also denoted as stocks 10_2 of the second group.

[0024] The main branches 42_1 and 42_2 of the stocks 10_1 of the first group are supported and attracted along the first attracting member 60_1, and the main branches 42_1 and 42_2 of the stocks 10_2 of the second group are supported and attracted along the second attracting member 60_2. As a result, the positions where the main branches 42_1 and 42_2 of the stocks 10_1 of the first group pass and the positions where the main branches 42_1 and 42_2 of the stocks 10_2 of the second group pass have a positional relationship shifted from each other in the Y direction.

[0025] Therefore, since the main branches 42 are supported and attracted along the same attracting member 60 only among the stocks belonging to the same group, the interference between the main branches 42 can occur only among the stocks belonging to the same group. As a result, it is possible to significantly increase the allowable distance until the main branches 42 interfere compared to the conventional configuration in which the main branches 42 of adjacent stocks can interfere with each other.

[0026] Subsequently, the effects achieved by the present embodiment will be described.

[0027] Figure 3 is a top view of a conventional grape cultivation system relating to a comparative example. In the conventional grape cultivation system, there is only one training member 60 in each row, so the main branches of all plants belonging to that row are trained along the same training member 60. As a result, the main branches of adjacent plants pass through the same position in the Y direction, making it easy for the main branches to interfere with each other and making it difficult to extend the main branches to a sufficiently long length.

[0028] In contrast, according to this embodiment, since the main branches of adjacent plants are supported and guided along different training members 60, they pass through different positions in the Y direction. This allows for a larger distance to be maintained before interference between the main branches occurs compared to conventional methods, enabling the main branches of each plant to grow sufficiently long while maintaining a high planting density. According to the embodiment described above, since the combination of plants in which interference between main branches 42 may occur is limited to the same group, it is possible to secure a larger distance than in the conventional method before the main branches 42 interfere with each other, making it possible to extend the main branches 42 of each plant to a sufficiently long length while maintaining a high planting density.

[0029] (Second Embodiment) Figure 4 is a schematic plan view showing the grape cultivation system 1 according to the second embodiment. This embodiment is a specific example in which the number of training members provided in each row is 3, that is, the number of training members N is 3, and compared to the first embodiment, it is a configuration that makes it possible to secure more positions through which the main branches pass in the Y direction.

[0030] The grape cultivation system 1 according to this embodiment, like the first embodiment, comprises a plurality of plants 10 arranged in rows along the X direction, a plurality of linear or rod-shaped training members 60 extending in the X direction and provided in each row, and a plurality of support posts 50 supporting the plurality of training members 60. The differences from the first embodiment will be described below.

[0031] In this embodiment, in each row, a plurality of guiding members 60 are arranged in the Y direction at a distance from each other, with a first guiding member 60_1, a second guiding member 60_2, and a third guiding member 60_3 extending in the X direction. These three guiding members 60 extend in the X direction and are arranged substantially parallel to each other. Furthermore, the three guiding members 60 may be arranged at the same height, or some or all of them may be arranged with a vertical offset.

[0032] In this embodiment, in each row, multiple plants 10 arranged along the X direction are classified into three groups: the first group, the second group, and the third group, based on their arrangement order. That is, among the plants 10 arranged along the X direction, the first plant in the arrangement order belongs to the first group, the second plant belongs to the second group, the third plant belongs to the third group, and so on, with the three groups being repeatedly assigned according to the arrangement order. Hereafter, the plants 10 belonging to the first group, the second group, and the third group will also be referred to as plant 10_1, plant 10_2, and plant 10_3, respectively.

[0033] The main branch 42 of plant 10_1 in the first group is supported and trained along the first training member 60_1, the main branch 42 of plant 10_2 in the second group is supported and trained along the second training member 60_2, and the main branch 42 of plant 10_3 in the third group is supported and trained along the third training member 60_3. As a result, the positions through which the main branch 42 of plant 10_1 in the first group passes, the positions through which the main branch 42 of plant 10_2 in the second group passes, and the positions through which the main branch 42 of plant 10_3 in the third group passes are offset from each other in the Y direction.

[0034] Therefore, as in the first embodiment, since the main branches 42 are supported and trained along the same training member 60 only among plants belonging to the same group, interference between the main branches 42 can only occur among plants belonging to the same group. This embodiment differs from the first embodiment in that the plants are classified into three groups, and as a result, it is possible to further increase the distance before the main branches 42 interfere with each other, making it possible to extend the main branches 42 of each plant to a longer length.

[0035] According to the second embodiment described above, the combination of plants in which interference between main branches 42 may occur is limited to the same group, similar to the first embodiment. However, since the plants are classified into three groups, a larger distance can be secured before the main branches 42 interfere with each other. As a result, it becomes possible to extend the main branches 42 of each plant to a longer length while maintaining a high planting density.

[0036] The present disclosure has been described above based on embodiments. These embodiments are illustrative, and it will be understood by those skilled in the art that various modifications are possible for each component or combination of processing processes, and that such modifications are also within the scope of the present disclosure. Such modifications will be described below.

[0037] In the embodiment, root-zone restricted cultivation using pots 20 was illustrated, but the technical concept of this disclosure is not limited thereto. Similarly, for plants 10 planted directly in the ground, by providing multiple training members 60 for each row and adopting a configuration in which the plants 10 are grouped and the main branches 42 are trained to the corresponding training members 60, it becomes possible to sufficiently extend the main branches 42 while maintaining the planting density, and as a result, yield can be improved.

[0038] In the embodiment and the above-described modifications, the example given is that the number N of training members 60 provided in each row is 2 or 3, but N may be an integer of 4 or more. In this case, the plants 10 constituting the row are classified so as to be repeated in N groups corresponding to the number N of training members 60, and the main branches 42 of the plants 10 belonging to each group are supported and trained along the corresponding training members 60. This configuration of increasing the number N of training members 60 is applicable when there is sufficient space to arrange training members 60 in the Y direction within the same row, and can be appropriately selected according to field conditions such as row spacing. With this configuration, it becomes possible to extend the main branches 42 over even longer distances.

[0039] In the embodiments and the modifications described above, the plants 10 are grouped based on their arrangement order, and the main branches 42 are guided to the training members 60 corresponding to each group. However, the disclosure is not limited thereto. As long as the main branches 42 of adjacent plants 10 in each row are supported and guided along different training members 60, the specific grouping method and the rules for assigning the plants 10 are not limited.
