The present invention provides a biodegradable, weed-preventing sheet comprising biodegradable fibers, and a method of preventing generation and growth of weeds using the sheet. The sheet contains coconut fibers as constituent fibers, exhibits naturally mild and slow biodegradability, and does not adversely affect the environment. Further, when the effect of the sheet becomes insufficient because of biodegradation during use, a new biodegradable, weed-preventing sheet can be laid thereon and used without adversely affecting the environment. Further, the sheet has significantly improved weatherability, durability and mechanical strength. Accordingly, the sheet resists breakage due to its mechanical strength. It has excellent light-shielding properties and suitable water permeability. The sheet is not cleaved by the growing force of vigorously growing plants of the Gramineae family. The sheet is also resistant to breakage by dogs and digging by mice and is impenetrable by weed seeds. |
