In addition, the present invention relates to a pressure-sensitive adhesive sheet for seeding and raising seedlings, which is suitable for significantly improving the workability of seeding.

る。Seeding work for grains, vegetables, flowers, etc. is roughly divided into the following 2
It is done by a variety of methods. That is, one method is a so-called direct sowing method in which seeds are directly sown in a field, and the other method is that seeds are once sown in a small-area seedling mat or the like for germination and seedling, and then seedlings are planted again. Is the way. Up to now, seeding was performed manually in any of the above-mentioned methods, but in recent years, the importance of improving workability has increased with the decrease in the number of agricultural workers and the aging thereof. Further, in the past, since the quality of seeds was uneven, it was inevitable to sow seeds in excess of the required number and to leave thin healthy seedlings after germination for thinning. However, in recent years, the seed quality and germination rate have been improved by the hybridization (F 1 ) of seeds, so that it is strongly required to significantly reduce the seeding amount.

た。The following methods have been proposed for the purpose of improving the above problems. That is, (1) a method in which seeds are wrapped in a water-soluble tape at appropriate intervals and embedded in a field,
(2) A method in which seeds are wrapped in a tape having a water-soluble pressure-sensitive adhesive layer on the surface of a water-soluble support to wrap seeds at appropriate intervals in order to fix the seed position (Japanese Patent Application No. 62- 206492
No.), (3) a seed having a small diameter is coated with a protective agent to increase the particle size and uniform the shape (hereinafter, this type of seed is referred to as a coated seed), and a simple hand-operated seeder is used. For example, a method of sowing in a field is used. However, even in this case, the manual work portion was not sufficiently removed.

を得ない状態にあった。On the other hand, in hydroponics, which has been rapidly expanding in the fields of use in recent years, once germinated, seedlings are placed by placing a fixed number of seeds at a fixed interval on a small-area urethane seedling mat or the like. After that, the procedure for planting seedlings is taken, but in this case as well, since the seeds have various sizes and shapes, it is common to sow them by hand. In particular, when expensive seeds are used, so-called dot placement is required to place the desired number of seeds at the desired position on the seedling raising mat, so the work must be done manually. there were.

ことによって達成することができる。For the above purpose, a water-insoluble or water-dispersible paper (water-soluble polymer film or the like) is applied in a dot-like manner on a water-absorbent support to fix seeds on the adhesive. Achieved by using a pressure-sensitive adhesive sheet for sowing and raising seedlings, which is configured so that the coating area of the dot-coating pressure-sensitive adhesive is adjusted so that the fixed seeds are sufficiently watered when the support absorbs water. be able to.

After spraying seeds evenly on the pressure-sensitive adhesive coated surface of the pressure-sensitive adhesive sheet, the seeds in a region other than the pressure-sensitive adhesive coated portion are removed by an operation such as tilting the pressure-sensitive adhesive sheet, or a container with a flat bottom The seeds are evenly placed in the above, the above-mentioned pressure-sensitive adhesive sheet is covered with the pressure-sensitive adhesive coated surface facing downward, and pressure is applied from above with a roller or the like.

得る状態となる。Next, the area where the adhesive is coated on the support will be described.
First, a water-soluble or water-dispersible pressure-sensitive adhesive as previously proposed by the inventors of the present invention is applied to a water-soluble or water-dispersible sheet-like support in spots to obtain a pressure-sensitive adhesive sheet (Japanese Patent Application No. 63-127043). In this case, after the seed is adhered onto the adhesive, the seed-carrying adhesive sheet is placed on a nursery mat or a nursery bed that has been sufficiently watered beforehand, and then the adhesive is first water-supplied through the support. Since water is absorbed and gradually dissolved in water to supply water to the seeds, from the viewpoint of water supply to the seeds, there is no limitation on the coating area of the dot coating adhesive. However,
In this case, the sticking of the seed to the pressure-sensitive adhesive is released relatively early after water is supplied to the sheet-like support, and the seed is allowed to move freely.

る。On the other hand, when a non-water-soluble pressure-sensitive adhesive is used as the pressure-sensitive adhesive, there is a close relationship between the size and shape of the seeds to be mounted, the number of adhered particles and the pressure-sensitive adhesive coated area. That is, if the adhesive coated area is larger than necessary compared to the size of the seed, water supply to the seed is likely to be hindered due to the water insolubility of the adhesive, and the expected germination rate cannot be obtained. become. The size and shape of the seeds to be loaded vary depending on the type of crop, and the diameter is the same as Komatsu greens.
Since there are various types of seeds, such as spherical seeds less than 1mm, spherical coated seeds with a diameter of 3-4mm, and flat and elongated seeds with a length of 3-5mm, such as salad vegetables and honeysuckle,
As a means for coping with this, a desired number of seeds are mounted per one part of the point adhesive depending on the size and shape of the seeds to be mounted, and moreover, all mounted seeds regardless of the mounting state. It is necessary to determine in advance the area of the adhesive coating part that can be supplied with water. For example, in the case of a circle with a dotted coating adhesive area of about 0.8 mm 2 , bare seeds of komatsuna, coated seeds of salad vegetables, etc. are mounted one per adhesive coating part, but Mitsuba, An average of 2 naked seeds such as green onions and 4 to 5 naked seeds of salad vegetables and lettuce are mounted. In the case of a dot-coated adhesive having a circular shape with an area of about 3 mm 2 , the coated seeds of salad vegetables are 1 grain each, and the average of 2 seeds of komatsuna
Three grains, mitsuba and green onions are loaded on average 3 to 4 grains. In any of the above cases, by placing an adhesive sheet loaded with seeds on a seedling mat or a nursery bed that has been sufficiently permeated with water in advance, all the loaded seeds can be sufficiently watered, and the present adhesive sheet is used. It is possible to obtain a germination rate that is not significantly different from that in the case of manual sowing.

合には発芽率が殆ど０となることが知られた。この結果
から、非水溶性の粘着剤を用いる場合、塗工部面積は少
なくとも９mm2以下であることが望ましいことがわか
る。Here, as a result of an experimental study on seed mountability and water supply to mounted seeds when the area of the dot-coated adhesive was variously changed, it was found that most of the adhesive-coated areas were 9 mm 2 or less. The seeds of vegetables and flowers are easily loaded and watered, and the germination rate is not significantly different from the case of manual sowing. The germination rate of seeds is manually sowed as the adhesive coated area becomes larger than 9 mm 2. More varieties (eg, salad vegetables, lettuce, and its naked seeds) are decreased compared to the case of
It was known that the germination rate was almost 0 when the area coated with the adhesive was sufficiently large with respect to the size of the seed. From this result, it can be seen that when the water-insoluble adhesive is used, the coated area is preferably at least 9 mm 2 or less.
なお、非水溶性粘着剤を用いた場合には、種子の表皮が
粘着剤に貼着している状態が長時間保持され、従って、

になる利点がある。In the case of using a non-water-soluble adhesive, the state in which the epidermis of the seed is attached to the adhesive is maintained for a long time, and therefore,
Since the seeds are fixed at the initial sticking position, there is an advantage that the rooted roots can be easily extended into the medium and detached from the seed coat of the bileaflet.
