Description of the Related Art Generally, as a method for storing seeds, there is known a method of storing the seeds at a low temperature, storing them in a dry state, or storing them in combination. Gel-coated seeds are small seeds or seeds that were previously unsuitable for mechanical sowing.
Or non-spherical seeds, etc., which is effective in facilitating seed sowing and facilitating germination by making it possible to mechanically sow seeds.
However, in these techniques, it was necessary to continuously perform the process from coating to seeding. For storage, a method in which the seeds are kept at a low temperature of about several degrees Celsius is conceivable. However, even with this method, the seed germination process cannot be completely suppressed, and it has been difficult to store the seeds for more than one month for a long time. On the other hand, a method of drying the gel-coated seeds is also conceivable, but it has been difficult to absorb the gel-coated seeds once dried and return to the original state.
