< Topic >In order to improve the productivity of the mushroom cultivation which uses the cultivation bottle, the cultivation bottle which quite can fetch the nutrient medium easily from the cultivation bottle is offered.SolutionsIn order the cultivation bottle major diameter Bga of caliber Ato bottle bottom 3 of mouth of a bottle 2 is equal, or also for major diameter Byori of caliber Awo bottle bottom 3 of mouth of a bottle 2 to become large, it forms. Therefore as for bottle body 1 from bottle bottom applying on the mouth of a bottle, verticality?, or from bottle bottom applying on the mouth of a bottle, in order to keep becoming wide, in order for gradient to be attached, it forms. It is possible there is no fault from bottle bottom to the mouth of a bottle and cylindrical?, because or it becomes converse conical condition, to be, to fetch the nutrient medium of one lump from the cultivation bottle easily.< Choice figure >Drawing 2【課題】栽培瓶を用いたきのこ栽培の生産性を向上させるため、栽培瓶から培地を極めて容易に取り出すことができる栽培瓶を提供する。【解決手段】栽培瓶は、瓶口2の口径A’と瓶底3の外径B’が等しいか、瓶口2の口径A’を瓶底3の外径B’よりも大きくなるように成形されている。従って瓶胴部1は瓶底から瓶口にかけて垂直か、もしくは瓶底から瓶口にかけて広くなっていくように勾配が付くように成形される。瓶底から瓶口まで障害が無く円筒状か、もしくは逆円錐状になっているためいた、栽培瓶から容易に一塊の培地を取り出すことができる。【選択図】図2
