Mushroom bed cultivation bag

Abstract

Provided is a mushroom bed cultivation bag where a bag main body can be surely torn regardless of nonuniformity of a thickness of a filter, a material, and the like. A mushroom bed cultivation bag includes a vertically long bag main body which has an opened upper end and is formed of a plastic film formed by aligning molecules so that tensile strength of a vertical direction is higher than tensile strength of a horizontal direction, and a rupture handle fused with the bag main body at a position that is different from a position of the bag main body, and rupturing the bag main body to tear the bag main body. A fuse portion fusing the rupture handle with the bag main body is formed in a mountain-shape where a tear-initiation side (opening side of an upper end of the bag main body) faces upward.

Description

technical field [0001] The invention relates to a fungal bed cultivation bag used for artificially cultivating mushrooms such as shiitake mushrooms and frondosa frondosa. Background technique [0002] In recent years, mushroom bed cultivation bags made of plastic films have been frequently used in the artificial cultivation of mushrooms. [0003] When mushrooms are cultivated artificially using such a fungal bed cultivation bag, first, an artificial culture medium (fungal bed) obtained by mixing a nutrient source such as rice bran with a wooden substrate such as sawdust and adjusting the water content is filled in the fungal bed cultivation. The bag is sterilized by high-pressure steam or the like, and then the mushroom seed is inoculated on the above-mentioned fungus bed and cultured (cultivation step). [0004] In this case, since the bag for fungal bed cultivation is disposable, it needs to be inexpensive, and it is desirable to manufacture it with the structure as simpl...

Problems solved by technology

However, when the filter 103 with a large mesh size is used to manufacture the bag for fungal bed cultivation 100 proposed in Patent Document 1, the user may be provided with a bag for fungal bed cultivation in which the strength of the welded portion 104 is weakened. When tearing the bag main body 101, the filter 103 falls off, and the bag main body 101 cannot be torn

That is, although there are users who want to use a bag for fungal bed cultivation to which a filter 103 with a large mesh is welded, in the structure of the bag for fungal bed cultivation 100 proposed in Patent Document 1, there are cases where the bag may be different depending on the type of filter 103. The problem of changing the degree of tearing of the main body 101
