Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sowing tape suitable for seeding and raising seedlings in a field, and in particular, for sowing in which a predetermined number of seeds can be easily seeded at a predetermined sowing position in a field with a predetermined distance from each other. Regarding tape.

[0002]

[Prior Art]

 In recent years, in addition to the greenhouse cultivation method, the film mulching cultivation method has been adopted in various places for the purpose of early sowing of crops, extension of the growing period, prevention of damage due to various causes, improvement of quality, etc. There is a tendency. In this cultivation method, the field is covered with a film having holes formed at predetermined intervals, and sowing is carried out at the positions of the holes by manual sowing or by using a sowing device or a sowing tool.

[0003] At present, sowing work in the field is generally performed by hand, but in part, sowing by machines is also performed. Further, in some cases, so-called seed tape, in which seeds are enclosed in a water-soluble tape, is laid directly in the field for germination and growth by further promoting labor saving in sowing. In addition, a sheet for seeding and raising seedlings suitable for a cultivation method in which seeding and raising seedlings are performed in advance at a specific place and then planted has been recently developed (for example, JP-A-64-20035 and JP-A-1-296909). , Etc.).

[0004]

[Problems to be solved by the device]

 In the case of seeding and raising seedlings in the field, when seeding is carried out manually or by using a seeding device or a seeding tool, it is currently extremely difficult to sow seeds with a predetermined number of seeds and a predetermined interval. Therefore, it is necessary to perform thinning work after germination and growth, which requires a huge amount of time and labor.

[0005] Although attempts have been made to use seed tapes, there are problems that seedlings may be damaged by the fibers used for tape reinforcement, and the film opening in the film multi-cultivation method is problematic. It is extremely difficult to align the position of the seed contained in the tape with the position, and there is a problem that it is not possible to maintain an appropriate interval between the seed and the seed.

An object of the present invention is to solve the problems of the above-mentioned conventional techniques, and to sow a predetermined number of seeds at a predetermined sowing position in a field at a predetermined interval and easily. The purpose is to provide a seeding tape capable of

[0007]

[Means for Solving the Problems]

 The above-mentioned object is a seeding tape in which seeds are fixed on a tape-shaped support made of water-soluble or water-dispersible paper with an adhesive or pressure-sensitive adhesive, and the seeds fixed by the adhesive or pressure-sensitive adhesive are fixed. It is an adhesive or pressure-sensitive adhesive provided in dots in an area that is not larger than the area occupied by the seeds, the seeds are dispersed and fixed in a desired pattern, and cut at desired intervals in the width direction of the tape. It is possible to achieve this by using a seeding tape which is provided with a predetermined number of seeds and which can be cut into a slice.

Here, the shape of the tape may be any shape from the viewpoint of germination of seeds, but by making it into a roll shape, problems such as tangling of the tape can be prevented, and further, sowing In this case, the tape can be easily fed out. When the seeding tape of the present invention is applied to the film mulching method, the width of the tape is set to be smaller than the size of the holes provided in the film, and the holes are easily placed on the soil in the film. It is necessary to set the size so that it can be placed. The positions of the seeds mounted on the tape are preferably separated from each other so that the growth bodies from the adjacent seeds do not impair their growth, and the adhesive strength of the adhesive or the adhesive strength of the adhesive is It is necessary to have an appropriate strength so that the seeds will not fall off during normal handling.

[0009]

[Action]

 The use of water-soluble or water-dispersible papers or films as supports does not interfere with root growth of seedlings, and if these supports are biodegradable, soil contamination is avoided. It does not cause. In addition, it is important to make the size of the adhesive or pressure-sensitive adhesive provided on the support smaller than the size of the seed, which may impede rooting of the seed by the adhesive or pressure-sensitive adhesive. Is reduced. Even if the adhesive or pressure-sensitive adhesive is water-soluble, it takes a long time to dissolve to the extent that it does not hinder the rooting of seeds because the water supply is limited in the field. The effect of reducing the size of the adhesive or pressure-sensitive adhesive is great.

Spacing seeds between seeds is extremely important for reducing seedling development and thinning work during development. In the tape of the present invention, an adhesive or a pressure-sensitive adhesive is applied on a support at desired intervals, and seeds are sprinkled on the support to attach seeds at desired positions on the support at desired intervals. You can

Making the tape into a roll shape and making a notch in the support have no direct relation to the development or growth of seeds, but cut the tape to the desired length and place it on the soil. It's perfect for work. That is, the tape is not entangled with each other and is easy to cut.

When the tape of the present invention having the above structure is applied to a field, seeds can be rapidly sown at a desired position by a predetermined number of seeds, and the rooting of seeds is not hindered, so that the seedlings can be grown optimally. Can be seen.

Here, a support used for the seeding tape of the present invention, an adhesive or an adhesive provided on the support, a method for applying an adhesive or a pressure-sensitive adhesive, a method for mounting seeds, etc. will be briefly described.

First, as the support, a water-soluble film, a water-soluble paper or the like is suitable. Specifically, the water-soluble film is made of polyvinyl alcohol, and the water-soluble paper is fibrous carboxymethyl cellulose. There are materials made of a mixture of various fibrous water-soluble resins and wood pulp as well as materials made by combining various materials in layers. Since the support is likely to remain in the soil, it is desirable that it be biodegradable.

Next, the adhesive or the pressure-sensitive adhesive will be explained. To fix the seed on the support, various water-soluble natural adhesives such as glue and starch paste, organic solvent such as vinyl acetate copolymer, etc. can be used. Various soluble adhesives can also be used, but these adhesives solidify when the solvent disappears, so it is necessary to attach seeds while the solvent is still viscous. .. On the other hand, if an adhesive is used, it is possible to attach the seed to the support at a desired time after coating the adhesive, and after the seed is attached, the adhesive is cured to form the seed. Can be fixed. Adhesives include rubber-based adhesives, acrylic-based adhesives, and silicone-based adhesives, which are applied in an organic solvent solution or water emulsion state and dried to form an adhesive layer, or Alternatively, the pressure-sensitive adhesive layer can be formed as it is by coating in a heated and melted state. In addition, some adhesives change their properties by being crosslinked by heating, irradiation of ultraviolet rays, electron beams, etc. In the case of the present invention, such crosslinkable adhesives can be effectively used. Among these, an adhesive having the property of being crosslinked and cured by irradiation with ultraviolet rays to enhance the adhesiveness to an adherend is effective. In addition, in sowing tapes, an adhesive or pressure-sensitive adhesive is often used by coating it on a support in a small-diameter dot shape. Printability is required as a preferable property for fine coating. Many ordinary adhesives or pressure-sensitive adhesives having printability are commercially available, and these can be appropriately selected and used.

The application of the adhesive or the pressure-sensitive adhesive is carried out by printing the adhesive or the pressure-sensitive adhesive on the support at a desired size and at an interval. When using a pressure-sensitive adhesive, the solvent-based pressure-sensitive adhesive is dried after coating and used for seed loading. For solvent-free adhesives, apply directly to seeds after coating, or preliminarily partially crosslink the adhesives with heat, ultraviolet rays, etc. before providing to seeds. The size of the adhesive or pressure-sensitive adhesive to be applied, that is, the area of the adhesive or pressure-sensitive adhesive occupying on the support needs to be smaller than the size of the seed to be mounted. The seed size may vary even if it is the same type, and the size of the seed may be extremely small. Therefore, it is necessary to set the coating area for each variety so that the area of the adhesive or pressure-sensitive adhesive is small for most seed sizes.

Regarding the mounting of seeds on an adhesive or a pressure-sensitive adhesive, when a solvent-based adhesive such as polyvinyl alcohol is used, the seeds can be glued one by one before the solvent evaporates and the adhesive hardens. Drop on top and remove solvent. When using a viscous pressure-sensitive adhesive in the normal state, after coating, the seed is attached by a simple operation such as sprinkling the seed, and then the pressure-sensitive adhesive is cured to firmly fix the seed to the support. .. If the pressure-sensitive adhesive used has the property of being cross-linked and cured by ultraviolet rays, etc., the pressure-sensitive adhesive is solidified by irradiating it with ultraviolet rays or the like from the seed-mounting surface or the back surface of the support.

Note that the application of the adhesive or the adhesive, the mounting of the seeds, etc. are performed so that a large number of desired patterns are formed on the support having the largest area, and the operation up to the seed fixation is completed. After the completion, finally, a predetermined cut is made and cut into a predetermined width.

The support, the adhesive or the pressure-sensitive adhesive, the coating method, the seed mounting method, the tape shape, etc. used for the seeding tape of the present invention have been illustrated and described above, but the present invention is based on the contents of these examples. It is not limited.
