发明名称 Plant growth suppression device
摘要 A device for suppressing ground plant growth surrounding a monument comprises a plurality of plastic shield pieces interconnected with each other and anchored by spikes into the ground around the monument base. The lower surface of each shield piece is formed with a pair of longitudinal retaining tracks. The shield pieces are coupled together by plate members retained within the longitudinal tracks across interfaces between shield pieces. The spikes extend downwardly from the plate members to anchor into the ground. The device is usable for suppressing plant growth in any predetermined ground region.
