に至ったのである。Then, a large mesh is formed on the back net by water-absorption dissolution of the water-soluble thread or the second net at the predetermined intervals, and thus the adhesion between the fertilizer lump and the seedling-growing vegetation material on the slope is increased. However, since the fertilizer lump and the planting material for raising seedlings are still contained in the bag part of the net,
Spilling and misalignment of fertilizer lumps and seedling vegetation materials due to rainwater are effectively suppressed, and the planting of seed vegetation materials as seedbeds allows germination and growth of plant seeds to achieve greening on slopes, etc. As a whole, it is possible to provide a vegetative mat for raising seedlings, which is lightweight, has excellent workability, and is suitable for greening, and can be produced in a factory and can stabilize quality at low cost.
