It is a perspective view which shows the state which is cultivating a plant using 10 roughly.

In the figure, a cultivation container 10 is formed by assembling a used paper (perforated sheet material) 12 having a biodegradable plastic film on both sides and an infinite number of through holes 11 on the entire surface in a box shape. , Inside the cultivation bed X
Are housed in a sealed state and can be opened by the opening ribbon 13. The whole is shrink-wrapped with a biodegradable plastic film (not shown).

The perforated sheet material 12 has a basis weight of 20 to 100 g.
A biodegradable plastic film is laminated on the upper surface of waste paper re-paper-wrapped so as to have a weight of 30 g / m ² using a commercially available water-soluble binder. When pressed with a protruding heat roller, it can be manufactured by forming a large number of through holes 11.
The average hole diameter of the through hole 11 is 100 μm to 5 mm,
Preferably 100 μm to 2 mm, more preferably 20 μm
0 μm to 1 mm. In addition, the perforated sheet material 12 is manufactured by thermocompression bonding a biodegradable plastic film to the upper surface of the used paper while pressing with a heat roller, and forming a through hole by operating in the same manner as described above. Can also.

The biodegradable plastic film is obtained by regenerating “Lactron 700DA” into 100 parts by weight of a polylactic acid virgin pet (trade name “Lactron 700DA”: a thermoplastic biodegradable aliphatic polyester polymer) purchased from Kanebo Synthetic Fiber Co., Ltd. The mixed pellets obtained by mixing 20 parts by weight are dried by a hot air drier at 60 ° C. for 3.0 hours, and then extruded from a T die to have a thickness of 2 mm.
It is formed into a thin film of 0 to 100 μm, preferably 20 to 50 μm. The type and thickness of the biodegradable plastic film are not limited, and can be appropriately selected.

Then, by punching the perforated sheet material 12, an opening ribbon (opening means) 13 integrally formed so as to be cut off at, for example, a perforation is provided at a position to be the opening 14, and the whole is formed. Forming a formed sheet provided with a fold line (not shown) for assembling into a box shape, folding along the fold line, and joining a peripheral edge excluding an upper opening to a joining means such as heat sealing or an adhesive. And assemble into a box with a bottom like a milk pack.

Finally, after filling the inside with a predetermined amount of the soil X, the upper opening is fixed in a sealed state by, for example, heat sealing, and the whole is shrink-wrapped with a plastic film having a gas barrier. The cultivation container 10 of the first embodiment can be manufactured. It is a matter of course that, instead of shrink wrapping, it may be sealed and housed in a bag-shaped package, and the assembling style of the bottom portion 15 may be any as long as the cultivation soil does not leak. Assemble,
It may be formed.

Next, when the planting container 10 of the first embodiment is used, first, the shrink wrap (or bag-like package) is removed, and the soil X inside the planting container 10 is moved to the bottom 15. When opening along opening means (opening ribbon etc.) 13 and opening opening 14,
