Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a seeding sheet used for raising pine-shaped seedlings to be planted with a rice transplanter, in particular,
The present invention relates to a seeding sheet suitable for row sowing, in which rice seeds are arranged in a striped manner at regular intervals horizontally, and spot sowing, in which rice seeds are arranged in dots, at regular intervals in the vertical and horizontal directions.

[Conventional technology]

When raising pine-shaped seedlings using the above seeding sheets, if you want to use spot sowing or row sowing or change the spacing between row sowings, prepare several types of seeding sheets for spot sowing and row sowing and use them appropriately. , I was raising pine-shaped seedlings, but the following disadvantages arose.

[Problem that the invention seeks to solve]

That is, when raising multiple types of pine-shaped seedlings, it is necessary to prepare a variety of seeding sheets according to the composition of each pine-shaped seedling, and it is inconvenient for users to use different sheets, and Costs were becoming high.

An object of the present invention is to solve the above problem by allowing a plurality of seeding patterns to be selected using a single seeding sheet.

[Means for solving problems]

The feature of the present invention is to obtain a plurality of types of seed arrangement patterns in one seeding sheet, and the means for achieving this is to configure the seeding sheet as follows.

That is, a base sheet is coated with a plurality of stripes of adhesive layer in a certain direction at predetermined intervals, and a release sheet is attached to the base sheet by the adhesive force of the adhesive layer. A cut line is carved in the release sheet, a thread for controlling peeling is placed between the adhesive layer and the release sheet along the lines of the adhesive layer, and one end of the thread is peeled off. When the thread is stuck to the sheet and the release sheet is turned up from the fixed end side of the thread, the thread is left on the base sheet side and one part of the release sheet separates from the score line, forming a streak on the adhesive layer. The seeding sheet is constructed in such a way that when the release sheet is turned up from the free end side of the threads, the threads are separated from the base sheet together with the entire release sheet, and its functions and effects are as follows. That's right.

[Effect]

When the release sheet is peeled off from the free end side of the threads embedded in the seeding sheet, the entire release sheet is separated from the base sheet and the streaky adhesive layer is all exposed.
If rice seeds are attached to this adhesive layer, it can be used as a seeding sheet for row sowing. Conversely, if the release sheet is peeled off from the fixed end of the thread, part of the release sheet will remain on the adhesive layer and cover part of the adhesive layer, causing the adhesive layer to form a pattern different from the one described above. Since the seed rice is exposed, if the seed rice is attached to this adhesive layer, it can be used as a seeding sheet with a different rice seed arrangement than when the release sheet is peeled off from the free end side of the thread.

〔Effect of the invention〕

As explained above, a single seeding sheet can be used for two types of seeding sheets with the simple operation of peeling off the release sheet from different positions, so users should prepare only one type of seeding sheet. This makes handling and management easier. In particular, it was necessary to prepare a large number of seeding sheets for each seeding pattern in advance in anticipation of the possibility that the planned number of seedlings to be raised for each seeding pattern would be changed during seedling-raising work. For example, even if there is a change in the planned number of seedlings to be raised, this can be easily accommodated, and there is no need to prepare extra seeding sheets, which is advantageous in terms of cost for the user.

Also, for seed-seeding sheet providers, by simply changing the pattern of the cut lines carved into the release sheet, the remaining release sheet pieces can be removed from the adhesive when the release sheet is peeled off from the fixed end of the thread. The pattern that covers and hides the layers can be changed, making it possible to handle pine-like seedlings with various patterns. Furthermore, to change the seeding pattern, you only need to change the pattern of cut lines on the release sheet instead of changing the adhesive application pattern on the base sheet, which generally tends to be costly, so you can reduce the cost as much as possible. It is now possible to construct seeding sheets for both point sowing and multi-seed sowing.

〔Example〕

Embodiments to which the present invention is applied will be described below based on the drawings.

As shown in Figure 2, on the surface of a base sheet 1 made of paper-based material, a large number of parallel adhesive layers 2 are applied at regular intervals in the long side direction in the form of stripes several mm wide. , threads 3 are placed on each adhesive layer 2 along the adhesive application direction, and a release sheet 4 made of paper-based material is placed over the adhesive layer 2 and the threads 3.
The seeding sheet is constructed by temporarily adhering the base sheet 1 with the adhesive layer 2, and then peeling only the release sheet 4 from the base sheet 1 again.

The release sheet 4 has small closed loop (rectangular in this embodiment) perforation lines 4a cut at regular intervals along the adhesive application direction, corresponding to the adhesive layer 2 and the thread 3. Also, one end of each thread 3 is fixed to the base sheet 1, and the other end is not fixed to the base sheet 1 and is a free end.

As shown in Figure 1A, the thread 3 is attached to the base sheet 1.
When the release sheet 4 is peeled off from the side where it is adhered to, the part 4b of the release sheet 4 surrounded by the thread 3 and the cut line 4a carved in the release sheet 4 due to the adhesive force of the adhesive layer 2. The release sheet pieces 4b remain on the adhesive layer 2, and the portions of the adhesive layer 2 that are not covered by the release sheet pieces 4b appear on the base sheet 1 at regular intervals. If the seed rice M is attached to this adhesive layer 2, the seed rice M will be arranged on the base sheet 1 in the form of dots spaced at regular intervals in the vertical and horizontal directions, so that it can be used as a seeding sheet for spot sowing. After that is the 5th
As shown in the figure, seed rice M is placed on the seedbed soil 6 of the seedling raising box 5.
By placing the base sheet 1 to which is attached, and covering the base sheet with an appropriate amount of soil and watering, dot-sown pine-like seedlings can be obtained.

Next, as shown in FIG. The adhesive layer 2 is separated from the base sheet 1 together with the release sheet 4, and the entire adhesive layer 2 coated in stripes appears on the base sheet 1. If the seed rice M is attached to this adhesive layer 2, the seed rice M will be arranged in the form of vertical stripes with regular horizontal intervals, and can be used as a seeding sheet for row sowing. Subsequent seedling raising may be carried out in the same manner as described above.

[Another Example] As shown in FIG. 3A and B, threads 3 are applied to each layer of the adhesive layer 2 applied in stripes in the long side direction on the base sheet 1, and one end is attached to the base. It is fixed to sheet 1 and placed with the other end as a free end,
It is also possible to adopt a configuration in which a rectangular perforation-like cut line 4a that completely surrounds this adhesive layer 2 is carved in a portion of the release sheet 4 corresponding to the adhesive layer 2 where the thread 3 is disposed. In this way, when the release sheet 4 is peeled off from the fixed end side of the thread 3, the release sheet piece 4b remains due to the adhesive force of the adhesive layer 2, as shown in FIG. layer 2
appears on the base sheet 1 every other line. Conversely, if the release sheet 4 is peeled off from the free end of the thread 3 along with the thread 3, the release sheet piece 4b will also separate from the base sheet 1 together with the release sheet 4 due to the action of the thread 3, and all the stripes of the adhesive layer 2 will be removed from the base sheet. 1 and can be used as a seeding sheet for row sowing, which can be used with two types of horizontal spacing.

As shown in Figure 4 A and B, the base sheet 1
A perforated cut line 4a in a rectangular shape surrounding one half of the adhesive layer 2 along the direction of the stripes is formed on the part of the release sheet 4 corresponding to each layer of the adhesive layer 2 applied in a striped manner on top. A configuration is also adopted in which the thread 3 is placed on the base sheet 1 at a portion corresponding to the release sheet piece 4b surrounded by the cut line 4a, with one end fixed to the base sheet 1 and the other end left as a free end. can. If you do this, the fourth
As shown in Figure A, when the thread 3 is peeled off from the fixed end side, the release sheet piece 4b remains due to the adhesive force of the adhesive layer 2, and each strip of the adhesive layer 2 is separated from one side along the strip direction. Only half appears on base sheet 1. Conversely, if the release sheet 4 is peeled off along with the yarn 3 from the free end side of the yarn 3, all of the adhesive layers will be exposed on the base sheet 1, resulting in a seeding sheet for row seeding that can be used with two different seeding widths. Can be used as
