摘要: A first frame capable of holding humus in which seeds of a plant are embedded to obtain the rapid germination of the seeds, with the first frame being supported on a second frame in which fertile soil is contained. The seedlings resulting from the germination of the seeds have roots that extend downwardly into the soil in the second frame. The first frame has manually operable means mounted thereon for severing the seedling roots in the first frame from those in the second frame to permit the two frames to be separated. The sod seedlings are removed from the first frame and the sod then planted in the field. The apparatus is particularly well adapted for producing sod seeding plantings.
