Seedling pad and kind subcovering subassembly that is used for seedling pad

The utility model provides a seedling pad and kind subcovering subassembly that is used for seedling pad, the seedling pad includes: the planar base plate of takeing root roughly, wherein the seminal root is grown and is supported and should to take root the base plate be that the oneself supports, and the coating has the seed adhesive on the one of which is surperficial for be fixed in the seed on the top surface region of the base plate of maybe should takeing root in this base plate of takeing root, plant the subcovering subassembly, this kind of subcovering subassembly covers the seed and permit the seedling to pass it and grow, and a plurality of seeds, these a plurality of kinds of molecular distributions maybe should take root in this takes root the base plate on the top surface region of base plate and through the bonding of seed adhesive to it on, wherein: this kind of subcovering subassembly is that the oneself supports and be the organic material of a self - supporting layer including compressed.
