Lower end support roller 42
Then, the glue is completely dried by the main drying device 43, cut by the cutting device 44 to a predetermined length, and the production of the seed paper is completed. The size of the seed paper produced in this manner is, for example, the same as the size of a conventionally known nursery box, and is placed on the bed soil filled in the nursery box and irrigated in a nursery facility or the like. Although the seedlings are grown, the paper sheet P and the paste dissolve in water when watered, which does not hinder the germination and growth of the seeds. In addition, the seeding amount may be one seed or two to three seeds at one place, and in some cases, it may be in a state close to row seeding, and in that case, the installation form and the installation amount of the paste are appropriately selected.

Further, in the above-mentioned embodiment, the whole manufacturing apparatus can be automatically operated continuously, but this is manually operated by using a batch type in which each paper sheet is cut into a predetermined size. It is also possible to install the paste in the supply unit 3 and supply the seeds in the seed supply unit 19 so as to be used separately from the apparatus.

〔The invention's effect〕

As described above, according to the seed paper manufacturing apparatus of the present invention, the seed supply unit that supplies seeds to the paste arranged on the paper sheet receives the seeds sorted one by one and receives the seeds by a predetermined number. Since the first shutter for sending out and the second shutter for supplying the seed sent from the first shutter onto the glue arranged on the paper sheet, the seed for each row in the first shutter is used. When the seeds are aligned, the first shutter is opened and sent to the second shutter, the second shutter is opened and the seeds are sown toward the glue already arranged. It is necessary to wait until the seeds are aligned for each row. It is possible to perform sowing work with high accuracy and without timing. In addition, there is no time loss, and efficient seeding work can be performed. Furthermore, the seeding action can be easily performed by arbitrarily setting the number of seed grains for each row.
