VEGETATION MAT AND SEEDLING RAISING STRUCTURE USING SAME

Номер: KR2012033259A1
Автор: KIM, You Duck
Принадлежит:

The present invention relates to a vegetation mat and a seedling raising structure using the same, and the invention comprises: a base member which is made of a bio-degradable material; a mat unit which is combined with an upper part of the base member by a coupling means such that a filling space is formed in the upper part of the base member, and has a cover member that is made of a bio-degradable material; and a vegetation member which is filled into the filling space, and has a bio-degradable speed adjustment member for adjusting the bio-degradable speed of the base member and the cover member. According to the present invention, since the vegetation mat and the seedling raising structure use the same bio-degradable speed adjustment member which adjusts the bio-degrading speed of the base member and the cover member inside of the mat, the growth of the vegetables that sprout and vegetate inside the mat are not obstructed by the mat.
