Abstract

To provide a fungus bed cultivation bag that prevents mushroom spawn film from tearing when the fungus bed is removed from the bag and can surely form the fungus bed in an appropriate shape. The fungus bed cultivation bag includes body parts opposing in the front and the back, a folding gusset part connecting to both sides of the body parts, a bottom seal part formed by heat-sealing the lower ends of the body parts and an inclined seal part formed by heat-sealing the lower end sides of the body parts and the folding gusset part in an oblique direction.

Abstract

[Problem] To provide a bag for mushroom bed cultivation which eliminates a pressure difference between the inside and outside of the bag during heat sterilization without the need for insertion of another member, which can favorably prevent hardening of the mushroom bed inside the bag that would be caused by shrinking of the bag due to a pressure difference, which enables a decrease in work and time for a heat sterilization step and an inoculation step for a mushroom inoculum, and which can reduce the cost of mushroom bed cultivation. [Solution] A bag for mushroom bed cultivation formed from a plastic film, said bag for mushroom bed cultivation comprising: a bag main body 2 the upper end of which is open and the lower end of which is closed; a vent hole 3 which is formed at an upper part of the bag main body 2; a filter 4 which is fused to the bag main body 2 in a manner covering the vent hole 3 and which prevents the entry of germs while allowing the passage of air; and a slit 5 which is provided at a position that is at the upper part of the bag main body 2 and in the vicinity of the vent hole 3. The bag for mushroom bed cultivation may have second filter 6 which is fused to the bag main body 2 in a manner covering the slit 5.

Abstract

[Problem] To provide a fungus bed cultivation bag wherein a fungus bed can be removed from the bag without breaking a hyphal membrane, and the fungus bed can be surely formed into a suitable shape. [Solution] This fungus bed cultivation bag 1 is formed from a plastic film, and is provided with: body surfaces 20, 21 disposed to face each other in the front-rear direction; folded gussets 22 connected to both sides of the body surfaces 20, 21; a bottom seal 23 formed by thermally fusing the lower ends of the body surfaces 20, 21 and the folded gussets 22; and an inclined seal 27 formed by thermally fusing the lower end sides of the body surfaces 20, 21 to the folded gussets 22 in an oblique direction.
