JP5833739B2 - IC tag for plants and method for producing IC tag for plants - Google Patents

Description

  The present invention relates to an IC tag technology. Moreover, it is related with the technique of growth (cultivation) of a plant (crop).

  IC tags (RFID tags and the like) are used in various fields and applications.

  Conventionally, in the field of plants, it has been practiced to manage information by tying tags (or stickers, etc.) to grown plants (or harvested crops) with strings (or sticking stickers, etc.) and handwriting information necessary for the tags. It was. However, it is easy to make mistakes such as mistaken tags for similar plant names and plant price tags that are difficult to see visually, and individual management was not sufficient.

  In the field of plants, as an example of technology using an IC tag, it is possible to manage distribution and sales by attaching an IC tag to a plant individual after harvesting with a string or the like (traceability management).

  Examples of prior art relating to plant individual management and traceability management include JP 2011-248741 A (Patent Document 1) and JP 2007-130007 A (Patent Document 2).

  Patent Document 1 (“agricultural crop traceability system”, etc.) describes a technique for tracing and managing from farmland to a collection warehouse, a transporting machine, and a delivery destination delivery warehouse like a grain after harvesting. According to Patent Document 1, “the crop traceability mechanism is assigned after the first ID is given to the storage or work place, and ID is given to a crop that is handled in bulk like a grain. It is difficult, so there was no guarantee that it was properly harvested from the target farmland. " Moreover, it describes the relationship between the ID of a machine (such as a harvesting machine) and the ID of a feature (such as a farmland or a warehouse) using positional information (GIS or GPS) (relation between a farmland and a crop).

  In Patent Document 2 (“cultivation history management method for agricultural products”), the cultivation area, cultivation time, cultivation method (cultivation conditions) are determined (identification / authentication) by genetic testing of individual crops (plants), and cultivation history management is performed. The technology to the effect is described.

JP 2011-248741 A JP 2007-130007 A

  At the stage of distributing grown and harvested plants, individual management and traceability management using IC tags and the like are realized. However, at the stage of plant growth, it is difficult to attach an IC tag to a plant individual, that is, a seed (seed) state or a plant such as a seedling that does not grow so much. Management is not fully realized. For example, an IC tag is larger than a seed, and it is difficult to attach an IC tag to a seed or a seedling, so that it is difficult to keep the state. Also, for example, even if an IC tag is placed near a seed planted in soil, the positional relationship with the IC tag fluctuates in the process of seed germination and growth, and the positional relationship becomes unclear. It cannot be managed.

  In addition, since the seed or seedling medium (soil) contains moisture, it is difficult to use an IC tag that handles electromagnetic waves. That is, radio waves are exchanged between an IC tag and a tag reader / writer device that reads and writes ID information and the like, but there is an instability that the response is lowered by absorbing the radio waves into the moisture of the medium.

  It is difficult to trace and manage individuals from germination to harvest (growth stage) of one seed with the technique as described in Patent Document 1. In addition, the technique as described in Patent Document 2 cannot detect instantaneously, non-contact, and non-destructively like an IC tag.

  In view of the above, the main purpose of the present invention is non-contact and non-destructive individual management (ID) for the process from the seed state of plants through the stage of growth such as germination and seedling to harvesting. Information management, etc.).

  A typical embodiment of the present invention is an IC tag or the like and has the following configuration. The IC tag of this form is a non-contact and non-destructive individual management (ID information management) for the process from the seed state of plants (crop) to the harvesting through germination and seedling growth stages. Etc.).

  The plant IC tag of this embodiment includes an antenna part, an IC chip, and a waterproof main body part that covers them. The main body has a shaft extending in the vertical direction and one or more protrusions extending in the horizontal direction from the shaft. The protrusion has a seed attachment part that attaches and holds plant seeds.

  Further, in the plant IC tag, the position of the protrusion and the seed attachment portion with respect to the longitudinal direction of the shaft portion is determined when the tag is planted in the ground with the seed attached to the seed attachment portion. It is designed to be at a position below a predetermined length from the ground. With the above configuration, when the seed of the seed adhesion part has a part that grows upward and a part that extends downward, the position of the projection and the seed adhesion part stays at the middle point of the growth. Therefore, the position of this tag is maintained with respect to the growing plant.

  The plant IC tag includes a plurality of the projecting portions, and the projecting portions and the seed adhesion portions are provided at positions of two or more steps in the longitudinal direction of the shaft portion. When this tag is planted in the ground with the seed attached to the seed attachment part, when the seed grows and has a root part extending downward, the plurality of protrusions and shaft parts The shape is designed so that the roots are entangled.

  According to a typical embodiment of the present invention, non-contact and non-destructive individual management (ID) is targeted for the process from the seed state of a plant to the harvesting through germination and seedling growth stages. Information management). In particular, precise growth history management (growth method / environment) by information management such as cultivar information, fertilization information, weather information, pest damage, and drug application information based on plant individual management (ID information management, etc.) Management, detailed traceability management including growth stages, precision agriculture, etc.).

  Hereinafter, embodiments of the present invention (plant IC tags and the like) will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

  By using the tag 1 (FIG. 1) of the present embodiment, individual management (such as ID information management) is realized when the target plant is grown from the state of the seed 10 (time, process, work, etc.). That is, the individual management from the seed 10 stage to the harvesting is realized. Specifically, it is possible to realize a precise growth history management including a growth method including fertilization and agricultural chemicals and a management of the growth environment. The present embodiment is based on the idea that the seed is attached to the IC tag, rather than the conventional concept of attaching the IC tag to the seed.

[(1) Tag structure]
In FIG. 1, the structural example of the tag 1 (IC tag for plants, IC tag for seeds) of this Embodiment is shown.

  (1) The tag 1 has a main body part (covering part) 2, an antenna part 3, an IC chip 4, and a seed attaching part 7.

  (2) The main body 2 is waterproof (water resistant), is made of a material such as plastic, and covers the antenna portion 3 and the IC chip 4 so as to be incorporated entirely. The main body 2 includes, as components, a head portion 7 (including the hole portion 8), a projection portion 5 (having a seed attaching portion 6), a tip portion (foot portion) 9, and a vertical shaft portion. Have In the shaft portion, the antenna portion 3 and the IC chip 4 are arranged and built in the vertical direction. As an outer shape of the tag 1 (main body part 2), the main body part 2 (shaft part) has a substantially vertically long rod shape (flat plate shape) so that the posture of the tag 1 can be easily maintained when the tag 1 is planted on soil.

  (3,4) The antenna unit 3 and the IC chip 4 can be configured using a known technology IC tag (RFID tag or the like). In this configuration example, the antenna unit 3 is arranged vertically along the vertically long shaft portion of the main body 2. The IC chip 4 is disposed near the center of the antenna unit 3. The IC chip 4 stores at least ID information (identifier information used for individual management) in a memory. The external tag reader / writer device (FIGS. 2 and 30) can perform radio wave communication via the antenna unit 3 so that the ID information of the tag 1 (IC chip 4) can be read and written. For communication between the tag 1 and the tag reader / writer device (30), for example, radio waves in the microwave band or UHF band are used, and the tag 1 and the tag reader / writer device (30) are detected and identified in a non-contact state (ID information). Reading).

  (5) The protruding portion 5 (arm portion) is a portion that protrudes laterally with respect to the shaft portion of the main body portion 2, and includes one or more for one tag 1. A seed adhesion portion 6 is connected to each projection portion 5. In the present configuration example, as shown in the figure, the two protrusions 5 (and the seed adhesion portion 6) extending in the transverse direction with respect to the shaft portion are provided in a shape including a total of six in three stages in the vertical direction. That is, the overall shape is a rectangular comb.

  The projecting portion 5 (and the seed attaching portion 6) fulfills a function for rooting, which will be described later (FIG. 3). Further, when there are two or more protrusions 5 (seed attaching part 6) in the vertical direction as in this configuration example, depending on where the seeds 10 are attached, the seeds 10 below the ground (FIG. 2) The position (Y1) can be selected and adjusted.

  (6) Seed adhesion part 6 is a part which adheres and holds seed (seed) 10, and can be constituted by means using an adhesive, such as a double-sided tape. When the tag 1 is used, the seed 10 is attached to the seed attaching portion 6 of the projection 5 at the desired position as shown in the figure. The adhesive force of the adhesive material of the seed adhering portion 6 only needs to be a sufficient and minimum force to adhere and hold the seed 10. Moreover, the seed adhesion part 6 may be comprised not only with an adhesive etc. but with another means, if it is a means which can hold the seed 10 in the position. For example, as shown in a modified example (FIG. 8) described later, the joining portion when the projection 5 and the seed adhesion portion 6 are connected sandwiches the seed 10, and the seed 10 is held by the spring elasticity of the sandwiching. Such a configuration (means) may be adopted.

  In this configuration example, it is possible to attach / remove (replace) the seed adhesion portion 6 to the projection portion 5. The seed 10 and the IC tag 1 (seed attaching part 6) can be separated, and the seed attaching part 6 and the protruding part 5 (main body part 2) can be separated. Thereby, the reusability of the IC tag 1 (main body part 2) is high. For example, after attaching seed 10 to the seed attaching part 6 of the tag 1 and using it for plant growth, the seed attaching part 6 and the like are removed from the tag 1 (rewriting information on the IC chip 4 as necessary). The tag 1 can be reused.

  (7, 8) The head 7 is held by the grower (operator) when the tag 1 is planted (filled or inserted) on the soil 20 (FIG. 2) or when the tag 1 is removed from the soil 20. Can be used as a part. Moreover, it becomes a part which comes out on the ground 20 and is stuck when planted. Moreover, it becomes a mark which shows the location of the tag 1 in the ground 20 after planting. Moreover, it becomes a standard of how much the tag 1 should be inserted when planting the tag 1 with the seed 10 on the ground 20.

  The head 7 can be used to tie an arbitrary object (for example, a management tag) to the hole 8 with a string or rubber. The head 7 can be used when the hole 8 is tied (fixed) with a plant (plant grown from the seed 10) to be grown (individual management target) with a string or the like. Further, the head 7 can be used for grafting, which will be described later.

  (9) The tip portion 9 has, for example, a sharp shape so that it can be easily inserted when the tag 1 to which the seed 10 is attached is implanted in the soil 20 (FIG. 2).

  The dimensions of the tag 1 are, for example, that the length of the antenna unit 3 is about 10 cm for the UHF wave band and about 5 cm for the microwave band, and the predetermined lengths of the head 7 and the tip 9 are added thereto. A length is preferred. For more detailed dimensions and shapes, prepare variations of the tag 1 that design the number, spacing, size, length, etc. of the protrusions 5 according to the type of seed 10 (plant) to be applied. It is preferable to use them properly.

  In the configuration of FIG. 1, the tag 1 is a flat plate having a predetermined thickness as a whole, and a plurality of protrusions 5 with respect to the shaft portion of the main body 2 are provided at the same angle (same plane).

[(2) At planting]
FIG. 2 shows an example of an operation / state in which the tag 1 with the seed 10 attached is planted on the soil 20 by the grower (operator) in the growth environment of the target plant. 2A shows a state before the tag 1 with the seed 10 attached is planted on the soil 20, and FIG. 2B shows a state after the tag 1 with the seed 10 attached is planted on the soil 20.

In FIG. 2A, the growth environment includes various elements (conditions) such as soil (20), air (such as CO ₂ ), water, light, fertilizer, and agricultural chemicals. The growing environment includes open ground, house, and facilities. 20 corresponds to the ground, culture medium (soil), fertilization, nursery, pot, and the like. FIG. 2A shows an example in which one seed 1 is grown using one of the plurality of protrusions 5 and the seed attachment portion 6 of the tag 1.

  In FIG. 2B, the seed 10 attached to the seed attaching portion 6 of the protrusion 5 of the tag 1 after being planted on the soil 20 is at a position (Y1) slightly below the ground 20. Further, in this state, when the operator uses (operates) the tag reader / writer device 30 (RW) from above the ground 20, non-contact / non-destructive communication with the tag 1 occurs, and the IC chip 4 is connected. The stored ID information can be read / written. Thereby, individual management of seed 10 (target plant and its growth method) can be performed.

  Since the tag 1 (main body part 2) is waterproof and the tag 1 is arranged near the ground surface (20) (at the edge of the plant), when the tag reader / writer device 30 reads the information of the tag 1 The radio waves of communication are not easily absorbed by the moisture contained in the soil 20, and stable communication is possible. That is, individual management becomes more certain.

  As described above, the seed 10 and the protrusion 5 are arranged at a predetermined position (Y1) slightly below the ground 20 in accordance with the target plant. One of the features of the tag 1 is that it has a suitable shape corresponding to such an arrangement. When the tag 1 is planted in a state where the seed 10 is attached to the seed attaching portion 6, the protruding portion 5 in the vertical direction of the tag 1 and the position 1 (Y 1) below the ground 20 are set to a position (Y 1) below the predetermined length. The position of the seed adhesion part 6 is designed.

  FIG. 2B shows a case where a part (one) of the plurality of protrusions 5 of the tag 1 is planted in a connected state. The seed adhering portion 6 to which the seed 10 is not attached may not be attached from the beginning, may be removed and used, or may be used as it is and planted. FIG. 8 to be described later shows a modification regarding the seed adhesion portion 6.

[(3) During growth]
FIG. 3 shows a state in which the target plant 40 has grown to some extent, following the state of FIG. The seed 10 of the seed attachment part 6 germinates, and the buds / stalks 11 and the like grow upward, the leaves 13 grow, and the roots 12 extend downward. Here, from the position (Y1) of the original seed 10, the stem 11 and the like extend upward, and the root 12 extends downward, and the position (Y1) is an intermediate point of growth. Along with the growth, the force when the stem 11 and the root 12 are extended also acts on the tag 1, but because of the arrangement and the tag 1 structure as shown in the figure, the protrusion corresponding to the position (Y1) of the seed 10 5 (seed adhesion part 6) stays in the position (Y1) which is the hairline of the plant 40 near the ground surface. That is, the tag 1 is not easily moved with the growth of the plant 40 and stably holds the initial position (positional relationship with the plant 40). Since the arrangement is held in this way, reading of the ID information of the tag 1 does not depend on the growth of the plant, and stable communication is possible, and individual management becomes more reliable.

  Further, as shown in the figure, the root 12 that grows from the seed 10 and extends downward extends so as to be entangled with the shaft portion and the protruding portion 5 of the tag 1 ("rooting" and "rooting"). In this way, the shape of the protrusion 5 and the like is designed in the present tag 1 so that the roots and the like are easily generated. That is, in particular, it has a comb-teeth shape with a plurality of (multi-stage) protrusions 5. Since the root 40 and the like are generated in this way during the growth, the plant 40 and the tag 1 are hardly separated from each other, so that the positional relationship between the plant 40 and the tag 1 is maintained (the connection is further strengthened). Therefore, the individual management by reading the ID information of the tag 1 becomes more reliable.

  Even if the root-entangled state as shown in FIG. 3 does not occur so much during the growth, the tag 1 stays at the midpoint (growth) of the growth of the plant 40 as described above. 1 is arranged in the vicinity and the positional relationship is maintained.

[Overview]
In FIG. 4, the outline which looked down at the arrangement | positioning relationship of the plant 40 and the tag 1 from the ground 20 is shown. The center circle indicates the positions of the seed 10 and the stem 11, and the surroundings indicate the leaves 13. The tag 1 (flat plate shape) is disposed in the ground 20 (brow) near the seed 10 and the stem 11. The horizontal length of the protrusion 5 is preferably set to a length designed according to the distance (positional relationship) between the target seed 10 and the stem 11, for example.

[How to use]
The tag 1 can be used in various ways depending on the growth method of the target plant. 2 and 3 show the case where only one seed 10 is attached to one tag 1 and planted. However, the present invention is not limited to this, and two or more seeds 10 are provided in one seed attaching portion 6. May be planted, or seed 10 may be adhered to each of the plurality of seed deposition portions 6 for planting.

  For example, a growth method is possible in which a plurality of seeds 10 are attached to one tag 1 to grow and thinning of growing plants (such as leaving one of good quality) is performed according to the growth situation. As individual management at that time, one ID of one tag 1 is related to the plurality of seeds 10.

[Growth work (plant growth method)]
An example of the growth work (plant growth method) using this tag 1 is as follows. Individual management during the growth of the target plant is performed by the following steps.

  (1) The target seed 10 is attached to the seed attaching part 6 of the tag 1 by the grower (operator).

  (2) The tag 1 with the seed 10 is planted in the culture medium 20 by the grower. Using the position of the head 2 as a guide, the tag 1 is inserted to a predetermined depth with respect to the ground 20. Thereby, seed 10 is arranged in a predetermined position (Y1).

  (3) The individual can be identified and confirmed by reading and writing data information such as ID information stored in the tag 1 (IC chip 4) using the tag reader / writer device 30 as appropriate by the grower.

  (4) Furthermore, the grower may be able to input and refer to various types of growth information on a screen of an application of a computer (in cooperation with the tag reader / writer device 30) using the read information of the tag reader / writer device 30. For example, cultivar information, fertilization information, weather information, disease and pest damage, drug application information, and the like are associated with the ID of the target plant 40 (seed 10) and stored in a database, and growth history management is performed.

[Tag manufacturing method]
The manufacturing method of the tag 1 is as follows. In the manufacturing factory, for example, a step of sandwiching the antenna portion 3 and the IC chip 4 with a sheet of thermoplastic material such as plastic, and in that state, the body portion 2 is pressed and heat-sealed (see FIG. Heating / cooling), whereby the outer shape of the tag 1 (original part 2) is formed. Furthermore, the process etc. which attach the seed adhesion part 6 to the projection part 5 are provided.

  Furthermore, depending on the target plant, a step of attaching the seed 10 to the seed attaching portion 6 of the tag 1 may be provided at the manufacturing plant. Then, the tag 1 with the seed 10 is provided (sold) as a package. The grower can plant the package on the soil 20 as it is.

  As another manufacturing method, a manufacturing method including a step of preparing an IC tag having a rectangular shape or the like and cutting it so as to have an outer shape of the tag 1 (main body portion 2) of FIG. 1 is also possible.

[Grafting]
FIG. 5 shows a case of managing a graft as an example of use of the tag 1. The grafting means that two or more plant individuals (rootstock, hogi (grafting)) are bonded to each other by an artificial cut surface, and are performed for various purposes. For example, there are grafts such as melon, watermelon and tomato.

  In FIG. 5, a first plant (rootstock) 41 is an individual managed by the first tag 1A and grown to some extent, and a second plant (hogi) 42 is a second tag 1B. It has been grown to some extent by individual management. Then, these two plants (41, 42) are grafted on the cut surface as indicated by 43. In the case of such a graft, it is possible to perform contactless management of the rootstock 41 and the hogi 42 using the present tag 1 (1A, 1B) in a non-contact manner.

  As shown in FIG. 5, depending on the target plant and growth method, a plant stem or the like may be passed through the hole 3 of the head 2 of the tag 1 during the grafting work, as described above. Alternatively, the stem 11 and the hole 3 may be tied together with a string or the like. By associating the target plant with the tag 1 by such physical tying (fixing), individual management can be made more reliable. As for the hogi 42 side, the tag 1B may be removed from the soil 20 if the tag 1B is tied (associated) with the hogi 42 as shown.

  In the case of the conventional grafting, the individual management of the two plants to be grafted and the management of the combination thereof cannot be performed, but the individual management in the case of the grafting can be performed by using the tag 1 of the present embodiment. For example, it is possible to accurately grasp which varieties and growth history each of the rootstock 41 and the hogi 42, and the state (attributes) of the plants grafted into one by combining them. is there.

[Modification]
The following is mentioned as a modification of the tag 1 of the said embodiment.

  (1) FIG. 6 shows a first modification (1a) of the tag 1. 1a is a case where the number of protrusions 5 (seed adhesion portion 6) is two (only one step) and the lateral direction thereof is lengthened. In this case, although the degree of the above-mentioned root is lowered, there is a sufficient effect of staying the tag 1 at the predetermined position (Y1) as described above. Moreover, it becomes easy to adhere several seeds 10 by making one seed adhesion part 6 wide.

  (2) FIG. 7 shows a second modification (1b) of the tag 1. Reference numeral 1b denotes a shape in which the neck between the head 2 and the protrusion 5 is elongated, and the antenna 3 and the like are arranged inside the neck. Thereby, when the tag 1 is planted, the length of the portion coming out of the ground 20 is long, and the length of the portion where the internal antenna portion 3 comes out above the ground 20 is increased. As a result, when the tag reader / writer device 30 reads and writes information, radio waves are highly likely to be communicated in a portion above the ground 20, so that radio waves are hardly absorbed and communication stability is improved.

  (3) Further, as another modification, the above-described head 2 (hole 3) may be eliminated, and the number of portions that protrude upward from the ground 20 may be reduced. This is effective when it is preferable that the portion of the tag 1 that protrudes from the ground 20 is less in the process and work of growing the plant.

  Further, for example, the head 2 may have a shape parallel to the ground 20 or may be configured to be able to bend the head 2 so as to be in such a parallel state (as viewed from above as shown in FIG. 4). Sometimes the round head 2 is visible).

  In addition, for example, a scale may be placed in the main body 2 (shaft) of the tag 1 so that the position of the scale when the tag 1 with the seed 10 is planted on the ground 20 can be understood. . Thereby, the position (Y1) of the seed 10 under the ground 20 can be adjusted and held at a suitable position.

  Further, for example, the tag 1 is not limited to an overall flat plate shape, and a plurality of protrusions 5 may be provided with a rotation angle with respect to the shaft portion. For example, the shape takes into account the stability of the posture when planted, the degree of rooting, and the like.

  For example, the structure which eliminated the projection part 5 and the seed adhesion part 6 is also possible. In this case, the positional relationship with the target plant (seed 10) using the protrusion 5 and the seed adhesion portion 6 cannot be maintained, but the head 7 (hole 8) is used to bind the target plant. Individual management is possible.

  (4) FIG. 8 shows a third modification (1c) of the tag 1. This configuration (1c) is a structural example related to the attachment of the protrusion 5 and the seed attachment portion 6 of the tag 1 of FIG. 1, and the seed 10 is held by a mechanical spring holding structure without using an adhesive. It is an example that makes it possible. The seed 10 is sandwiched and held between the seed adhesion part 6 and the protrusion part 5. The adhesive part 6 is not coated with the above-mentioned pressure-sensitive adhesive (the coated form is also possible). Since the protrusion 5 and the seed attachment portion 6 can be separated, only the portion of the seed attachment portion 6 can be replaced as a consumable when the tag 1c is to be recycled. In 1c, the protrusion 5 and the seed adhesion portion 6 are components made of a flexible material (a property of bending when a force is applied) such as plastic. The seed attaching part 6 and the protrusion part 5 are each provided with cuts as shown in the figure, and when they are connected (attached), they are engaged with each other so as to be alternated by the cuts. At the time of connection, for example, of the three peaks (convex) shown in the figure, the upper and lower protrusions of the protrusion 5 and the intermediate protrusion of the seed attaching part 6 are on the front side, for example, and the intermediate protrusion of the protruding part 5 and the seed attaching part 6 The top and bottom protrusions of the are opposite (back) side. Then, for example, the seed 10 is arranged (attached) so as to be sandwiched between the front and back surfaces of the middle convex of both (5, 6). Thereby, seed 10 can be held at that position.

[After harvest]
The harvesting and distribution stages after the growth of the plant are as follows. When individual management is performed only at the growth stage, for example, at the time of harvesting / collecting, an operation of removing the tag 1 (bundled state) from the plant 40 is performed. The removed tag 1 can be reused.

  When individual management / trace is continuously performed after harvesting, for example, the plant 40 may be harvested / collected with the tag 1 attached, or data such as ID information that has been individually managed in the growth stage. Information may be linked and provided so as to be transferred to a traceability management system or the like in the distribution stage.

  Furthermore, it is possible to associate ID information with the price (price tag) at the time of seedling sales, and it is possible to identify varieties that cannot be judged at the seedling stage (for example, discrimination between shishito and chili).

[Effects]
As described above, according to the tag 1 of the present embodiment, the process from the state of the seed 10 of the target plant 40 to the harvesting through the stage of growth such as germination and seedling is targeted for non-contact.・ Non-destructive individual management (ID information management, etc.) becomes possible. Thereby, in particular, precise growth history management (growth method / growth) by information management such as variety information, fertilization information, meteorological information, pest damage, and drug spraying information based on individual management of plant 40 (ID information management, etc.) Environmental management Detailed traceability management including the growth stage, precision agriculture, etc.) becomes possible. It is also possible to manage breed improvement by grafting.

  Conventionally, when seeds are small in seed sowing work, for example, seeds are planted with tweezers in a nursery (pot or the like). In this case, for example, since the IC tag is larger than the seed, it is difficult to manage the individual by connecting the IC tag to the seed. In addition, it was difficult to manage individuals because mistakes (mistakes, etc.) related to seeds, nurseries, bills, etc. were likely to occur. On the other hand, if this tag 1 is used, individual management can be easily realized by attaching a small seed 10 and planting. In addition, since the tag 1 has an effective shape and the like as described above, the grower (operator) can easily perform work for individual management (the work load is small).

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

  The present invention can be used as a management technique for plant growth (cultivation).
