TACKY ADHESIVE SHEET FOR SOWING AND RAISING SEEDLING USE AND SOWING AND RAISING SEEDLING METHOD

摘要

PURPOSE:To obtain the subject sheet effective in promoting the growth of a plant in sprouting and raising seedling stages in high efficiency over a long period and capable of effectively sowing seeds on a raising seedling mat at a prescribed spacings by forming a tacky adhesive layer in spots or stripes on a substrate sheet using a tacky adhesive containing ferromagnetic powder. CONSTITUTION:The objective tacky adhesive sheet is produced by applying a tacky adhesive 2 containing ferromagnetic powder 3 to a substrate sheet 1 (e.g. a water-soluble polymer film) in spots or stripes. The ferromagnetic powder is magnetized to form S-pole e.g. on the substrate side. The sheet is placed on a raising seedling mat or on seedlings to perform the sprouting of the seeds 4 and the raising of the seedlings.
