PROBLEM TO BE SOLVED: To provide a mushroom bed cultivation method of ornamental Ganoderma lucidum which has appearance completely different from that of conventional Ganoderma lucidum and presents a white or yellow stag horn.SOLUTION: This mushroom bed cultivation method of ornamental white or yellow Ganoderma lucidum is performed in a housing and comprises inoculating hypha of Ganoderma lucidum to a mushroom bed followed by growing thick, storing the mushroom bed in a housing followed by holding, and keeping the housing in (A)-(C) conditions and raising carpophore of Ganoderma lucidum. (A) To cover the upper part of the housing with a semi-translucent material so as to bring a transmission rate to 65-85% until Ganoderma lucidum passes through bud cutting (sprouting) and infant Ganoderma lucidum starts to change color, after storing the mushroom bed in the housing. (B) To densely cover the upper surface of the housing with a shading material so as to increase airtightness and completely block light before the infant Ganoderma lucidum changes color to blackish brown after bud cutting. (C) To adjust a temperature in space of the housing to 25-35°C, and humidity to &ge90% and retain the condition.COPYRIGHT: (C)2009,JPO&INPIT【課題】 従来の霊芝とは外観が全く異なる白色ないし黄色鹿角を呈する観賞用霊芝の菌床栽培方法の提供。【解決手段】ハウジング内で行う霊芝の菌床栽培において、菌床に霊芝の菌糸を接種して密生させた後、前記菌床をハウジング内へ収納・保持すると共に、前記ハウジング内を、下記の(A)~(C)の条件に保持して霊芝の子実体を生育させることを特徴とする観賞用白色ないし黄色鹿角霊芝の栽培方法。(A)前記菌床をハウジング内へ収納後、霊芝が(Ganoderma lucidum)芽切り(発芽)を経て、幼霊芝が変色し始めるまでは、ハウジングの上部を半透光性の物体で覆い、透光率が65~85%になるようにすること。(B)芽切り後、幼霊芝が茶褐色に変色する前に、ハウジングの上面を遮光性材質で密に覆い、気密性を高めると共に光を完全に遮断すること。(C)前記ハウジング内のスペースの温度を25~35℃、かつ湿度を90%以上に調節・保持すること。【選択図】 図9
