The present invention relates to an environmentally friendly biodegradable grass seed vegetation container fixation structure which makes a grass vegetation container naturally discomposed, and is formed by including the following steps. A cultivation pot to accommodate culture soil which mixes grass seeds and artificial soil is formed in a biodegradable vegetation container (20). A latch groove (26) is formed in one side of the biodegradable vegetation container while a thick engagement protrusion (28) is formed in the other side. Engagement holes (28h, 26h) are formed in the engagement protrusion and latch groove, respectively. A flange nut (30) is inserted from the bottom surface of the biodegradable vegetation container, and a rotation preventive groove (29), which a flange is inserted into, is formed on the bottom surface of the biodegradable vegetation container. A hollow bolt (40) with a washer (44) is inserted into the engagement hole and is engaged with the flange nut. The biodegradable vegetation container is arranged on a biodegradable plastic mesh which is installed on a grass forming surface (10). The biodegradable vegetation container is fixated by fixating an anchor nail (60) on the grass forming surface through an anchor hole (42). An drawing ring (64) is installed to an insertion unit (68) of a head unit (62), and one directional elastic latch piece (70) is installed in a ring-shaped groove of the anchor nail. An avoidance groove (61) is formed in the outer periphery of the anchor nail, which the one directional elastic latch piece is located at. A biodegradable installation band (80) is installed at a location making latch which is formed at the periphery of the biodegradable vegetation container.본 발명은 잔디식생 후 용기가 자연적으로 분해되도록 한 환경친화적 생분해성 잔디 홀씨 식생용기 고정구조에 관한 것으로, 잔디 홀씨와 인공토양을 배합한 배양토(24)를 담기 위한 배양포트(22)를 생분해성식생용기(20)에 형성하고, 생분해성식생용기(20)의 가장자리 한쪽에는 걸림홈(26)을 형성하며, 반대편 가장자리에는 두툼한 결합돌기(28)를 형성하고, 결합돌기(28)와 걸림홈(26)에 체결공(28h)(26h)을 형성하며, 생분해성식생용기(20)의 저면으
