Abstract

PURPOSE:To obtain the titled sheet capable of simplifying operation required for soil covering and save labor in seedling raising work, by molding highly water absorbing, water-insoluble polymer particles, readily water-soluble polymer and water-insoluble powdery or granular substance into the form of a sheet. CONSTITUTION:(A) Highly water absorbing and water-insoluble polymer particles and (B) a readily water-soluble polymer and (C) a powdery or granular substance that is a water-insoluble substance without belonging to the polymer particles (A) are molded into the form of a sheet to provide a soil covering sheet 1, which is then laid on seeds 4 sowed on earthing up 2. When water is sprinkled, the polymer (B) is dissolved and the gelatinized polymer (A) absorbs water to form a gel. The powdery or granular substance (C) is separated into the respective simple substances and converted into a soil cover liberated between the polymer particles (A). Thereby the germination of the seeds 4 is promoted to facilitate the rooting thereof.
