PROBLEM TO BE SOLVED: To provide a system for producing seed-attached raising seedling culture medium further reducing the burden on a farm family. SOLUTION: The system for producing seed-attached raising seedling culture medium 20 comprises the following: a pretreated part 22 for forcing germination of paddy; an adhesive production part 24 producing an adhesive; a mat production part 26 producing a rice-hull mat 12; an adhesively seeding part 28 where pretreated paddy and covering soil material adhere to the rice-hull mat 12 to produce the seed-attached raising seedling culture medium; and a dry accumulation part 30 for drying and accumulating the produced seed-attached raising seedling culture medium. The pretreated paddy and the covering soil material are bonded, in advance, to the seed-attached raising seedling culture medium produced by the system for producing seed-attached raising seedling culture medium 20, and thereby use of the seed-attached raising seedling culture medium makes the farm family have no need of seeding work and soil covering work.
