Abstract

The invention is to provide a base paper for a raising seedling pot and a raising seedling pot produced from the base paper, wherein while the base paper maintains a sufficient strength during raising seedlings and planting in the field, it is degraded over time by soil microorganisms after transplanting in the field and is produced by using a crosslinking agent that does not contain formaldehyde, resulting in a reduced burden on the environment; the base paper for a raising seedling pot, wherein a citric acid crosslinking agent, as a crosslinking agent for cellulose, is used in order to block the hydroxy group of cellulose in paper through crosslinking; and the raising seedling pot produced by molding and processing the base paper.
