PROBLEM TO BE SOLVED: To provide a bag for cultivating mushrooms in which oxygen and hydrogen efficiently circulate and which suppresses the emission of water vapor to maintain suitable humidity inside the bag.SOLUTION: A bag 10 for cultivating mushrooms has a bag body 11 which includes a bottom surface 12 and side surfaces 13-16 installed upright from the periphery of the bottom surface 12 and in which the upper part facing the bottom surface 12 is opened. The side surface 13 has at least one first ventilation part 21 and at least one second ventilation part 25, the ventilation rate of which is lower than that of the first ventilation part 21. The second ventilation part 25 is provided at a position which is higher than that of the upper surface of culture medium 18 and which is lower than that of the first ventilation part 21 in such a state that the culture medium 18 is put in the bag body 11.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】酸素と二酸化炭素の循環が効率よく行なえ、且つ、水蒸気の放出を抑制し、袋内を好適な湿度に保つことができる茸栽培用袋を提供する。【解決手段】底面12と、底面12の周囲から立設された側面13~16と、底面12と対向する上部が開口された袋体11を有する茸栽培用袋10において、側面13には、少なくとも1つの第1通気部21と、第1通気部21より通気度の低い少なくとも1つの第2通気部25を有し、第2通気部25は、袋体11に培地18が詰められとき、培地18の上面となる位置より高い位置であって、かつ、第1通気部21より低い位置に設けられている。【選択図】 図1
