2. Description of the Related Art Conventionally, sowing work in a field is generally carried out by hand sowing, and in some cases, sowing is also carried out by a machine. In addition, so-called seed tape in which seeds are enclosed in a water-soluble tape, seed paper in which seeds are fixed on a water-soluble paper with an adhesive, etc. are put on the field or nursery for germination and raising seedlings. Some have been done. In addition, a seeding and raising seedling sheet suitable for a cultivation method in which seedlings are preliminarily sown at a specific place to grow seedlings has been recently developed (Japanese Patent Laid-Open No. 64-20035, Japanese Patent Laid-Open No. 1-296909, etc.). The seed tape, which was developed for the purpose of labor saving sowing, is a seed that is physically enclosed in a tape made of a water-soluble film so as not to fall off, but it is necessary to keep the position between seeds at an appropriate distance. Can be difficult and can injure the seedlings. Also, the seed paper is a seed fixed on a water-soluble paper with a water-soluble adhesive, and although it is excellent in fixing and setting the position of the seed, since the position where the adhesive and the seed are dropped is mechanically determined, Patterns with close seed spacing are difficult to produce, and are also difficult to apply to very small seeds. Since the seeding and raising seedling sheet developed in recent years is not intended to firmly fix the seeds, it is not necessarily suitable to arbitrarily perform the operation with the seeds mounted on the sheet.

Generally, it is extremely difficult to sow seeds at a predetermined number and at a predetermined interval when sowing by hand in a sowing operation or by using a sowing device or a sowing tool. Therefore, it is necessary to sow the seeds evenly, and perform thinning work after germination and growth.
This requires a huge amount of time and effort, and this labor saving is strongly demanded.

[Function] If a pressure sensitive adhesive having sufficient tackiness for capturing seeds to be sown is accurately applied at a predetermined position on a support such as water-soluble paper, the seeds can be sprinkled on the support to form a support. The seeds can be attached to the desired places of the plant at desired intervals. The pressure-sensitive adhesive can be applied in any form such as linear or dot-like, but dot-like application is superior for controlling the number of seeds loaded. In order to mount one seed in one place, the coated area of the adhesive must be sufficiently small compared to the size of the target seed. Screen printing is suitable as a method for applying a small-area pressure-sensitive adhesive with an arbitrary shape and interval. As the type of the adhesive, a commercially available adhesive can be arbitrarily selected and used as long as it has no inhibitory effect on germination of seeds, growth of seedlings and the like. When screen printing is applied, it is needless to say that the printability is excellent.

If a curable adhesive is used as the adhesive, it is possible to cure the adhesive after mounting the seeds and fix the seeds so that they will not fall off during normal operation. When fixing one at a time,
Since the pressure-sensitive adhesive also needs to be minute, the contact area between the seed and the pressure-sensitive adhesive is extremely small, and thus many seeds may drop off in the normal operation. Also, some seeds are difficult to fix. In such a case, coating with a water-soluble polymer becomes an extremely effective means.

When the thin film of the water-soluble polymer is formed so as to cover the surface of the seed mounted on the adhesive, the seed is firmly fixed to the extent that it does not fall off by a normal operation. The form of the polymer thin film may be a laminate film, or may be a film in which seeds are coated and penetrated into the support. This membrane should fix the seeds to the support until the sheet is placed on the germination bed, and it should dissolve quickly once watered on the germination bed so as not to prevent germination of the seeds.

Examples of water-soluble polymers having such properties include polyvinyl alcohol, polyvinylpyrrolidone, water-soluble acrylic resins, etc. as synthetic polymers.
Examples of natural polymers include cellulose derivatives such as carboxymethyl cellulose, methyl cellulose and hydroxypropyl cellulose, starch derivatives such as starch and carboxymethyl starch, and various polysaccharides such as alginic acid and pectin. Since these polymers have a film-forming ability and an adhesive ability, they can be used alone or in a mixture for seed fixation.

In order to fix the seeds mounted on the support through the adhesive with the above-mentioned polymer, the small part on which the seeds are mounted may be coated with a polymer and fixed, or the whole surface of the support may be fixed with the polymer. You may coat with. Screen printing is suitable for coating the polymer only on the seed mounting part.
In order to coat the entire surface of the support with a polymer, lamination of a polymer thin film, roll coating of a polymer solution, spray coating of a polymer solution, etc. are effective. When the polymer thin film is laminated, it is possible to form a multilayer structure of the support, the adhesive, the seed, and the polymer without changing the state of the support. When the polymer solution is applied,
Since the polymer penetrates into the support, it is possible to fix the seed in such a state that the seed and the whole support are solidified with the polymer.

The seeded seedling-growing sheet of the present invention having the above-mentioned structure can fix any seeds on the support at desired intervals and patterns without dropping off, regardless of the size of the seeds.
