PROBLEM TO BE SOLVED: To provide a simple greening system for preventing global warming, which is a compact germination device which allows a consumer to easily germinate plants and promote greening close to them, and which can be manufactured extremely easily and can be distributed to the market at low cost. SOLUTION: This is a three-dimensionally or two-dimensionally formed germination ground in which a plant seed 1 is coated with a laminate of biodegradable fibers, and the germination ground has air permeability and root permeability that penetrate from the surface of the laminate to the opposite side. The hole 5 provided is provided, and the seed 1 is molded by allowing the seed 1 to breathe by fitting the seed 1 into the hole 5 and passing through the hole opening 12 by elongation after germination. A water retaining layer 2 and a protective layer 3 each having water permeability and fertilizing property are provided in each layer, and both layers can supply water to the seeds 1 and components of the fertilizer/soil improving material 15 by water injection. It also has air permeability and rootability, and when the plant grows, it breathes and can penetrate the cross section of the laminate, and since it also has elasticity, the seed 1 and the above-mentioned improvement material 15 can be fitted between the laminates, and they face each other on the laminate surface. Each of the hole openings 12 is formed so as to releasably close it.
