Problem to be solved: to provide the moss products which can preserve the quality of the moss and maintain the fresh freshness of the moss.Solution: weeds, insects, etc., of the moss plant collected in the breeding area of the moss in the manufacturing process of the seaweed are removed in advance, and the temporary root assemblage is removed and the root of the weed mixed is cut off, and it is used as the seed moss.The dried box is covered with a light shielding net covered with a light intercepting net of 50% light intercepted Under the condition of 25 degrees centigrade or less, the water content was dried under the condition of 25 degrees under the moisture gauge, and the photosynthesis of the moss was stopped, and the drying of dried moss sheet was put into a dedicated bagIt is possible to store the moss sheet which can be kept for a long time by completely shutting off the air and moisture by using the vacuum.Selection diagram【課題】品質を均一化し苔本来の鮮度を維持した状態で長期保存できる苔商品を提供する。【解決手段】種苔の製造過程で苔の繁殖地で採取した苔植物の群体の雑草、昆虫等を予め除去した後仮根集合部を切除し混入している雑草の根切りを行い洗浄し種苔として使用する。栽培容器に防水シートを敷き透水性の良い基盤材を平に敷き詰め不織布を2層重ねの上に種苔を粉砕せずに均一厚に敷き詰め栽培農地で保管生育させる蒔き苔栽培法で所定寸法に生育採取された苔シート11を遮光率50%の遮光ネットで覆った乾燥専用箱の中で冷温風機を使用して25度以下で含水量を水分測定器で0%に近い状態に乾燥し苔の光合成を停止させ成長を休止状態にドライ乾燥した苔シートを専用の袋17に詰め減圧真空装置を使用して減圧真空状態とし空気と水分を完全に遮断して長期保存可能な苔シートを商品化する。【選択図】図11
