  • Publication number: 20040200147
    Abstract: A seedling culture mat includes a fibrous face layer, an intermediate layer, and a barrier substrate. The intermediate layer underlies the face layer, and includes a fibrous body, a plurality of seeds provided on the fibrous body, and a nutritional component applied to the fibrous body. The barrier substrate underlies the intermediate layer to guide primary roots which protrude out of the seeds to extend substantially along the barrier substrate before the primary roots project out of the barrier substrate. Thus, the primary roots and secondary roots which develop from the primary roots can be kept within the seedling culture mat for a prolonged period of time to take up the nutritional component.
