PROBLEM TO BE SOLVED: To provide a seeding device that reduces the number of man-hours of seeding work having much room for improvement on labor saving in the hydroponic culture, eventually reduces a manufacturing cost.SOLUTION: Two pieces of perforated plate with multiple through-holes arranged in a grid pattern in the same position are held in the state where the position of each through-hole may not match. A seed supply member comprising seed-dropping through-holes of the same pitch as the through-holes is made to slide on the upper side perforated plate, and a fixed quantity of seed is temporarily stored in the through-hole of the upper side perforated plate. Then, the lower side perforated plate is horizontally moved so that the position of each through-hole of the upper side perforated plate and the lower side perforated plate may be matched with each other in the state where a culture medium provided with seed-storing bottomed holes of the same array as the upper side perforated plate in the lower part of a lower side perforated plate is arranged so that the position between the seed-storing bottomed hole and the through-hole of the upper side perforated plate may be matched with each other. Thereby, the seed passes the through-hole of the lower side perforated plate and drops in the seed-storing bottomed hole by own weight.SELECTED DRAWING: Figure 1 |
