< Topic >Time excessively does not bet on the maturation where the shiitake reaches before the budding sun/size, in addition, relatively immature being, the margin of propagation of the hypha is left and because activity is continuous, the maturation artificial bed log of the shiitake which big well the shiitake of quality can grow is offered with the thick meat.SolutionsCoat of nutrient medium Pa after the bag tearing of the retort sack 1 which internalizes the nutrient medium of block condition, from ocher changing in tannage with the breeding of the hypha, in the maturation artificial bed log of the shiitake which becomes, in order the surface of the nutrient medium before that bag tearing to be covered with coat of white or marbling condition by the breeding of the spawn, top of the above-mentioned retort sack 1 ventilation suture possibly with the machine sewing thread.< Choice figure >Drawing 1【課題】椎茸が発芽寸前に至る熟成に時間が余り掛からなく、また、比較的に未熟であっても菌糸の繁殖の余地が残され活性が持続されているために、厚肉で大きな良品質の椎茸が発育させ得る椎茸の熟成人工榾木を提供する。【解決手段】ブロック状の培地を内蔵したレトルト袋1の破袋後の培地Paの被膜が、菌子の増殖により黄土色から茶褐色に変化してなる椎茸の熟成人工榾木において、その破袋前の培地の表面が種菌の増殖により白色ないし霜降り状の被膜で覆われるように、上記レトルト袋1の上部がミシン糸によって通気可能に縫合した。【選択図】図1
