...To ensure smooth heat generation, several types of organic matter must be mixed appropriately to achieve a carbon ratio of 30 to 40. When using electric heat as a heat source, straw or rice husks are laid at the bottom of the hotbed as insulation, then sand is added, hotbed wires (iron-chromium heating wires covered in vinyl) are buried in the sand, and bed soil is added on top of that. In a hotbed that uses fermentation heat, the bed temperature gradually drops, but in an electric heated hotbed, the bed temperature can be kept constant indefinitely. *Some of the terminology that refers to the "hotbed line" is listed below.

…発熱を順調に行わせるためには,数種類の有機物を適当に配合して炭素率を30~40にしなければならない。熱源として電熱を利用する場合には,温床の底に断熱材としてわらやもみがらを敷き,次に砂を入れて,その中に温床線(鉄クロムの電熱線をビニルで被覆したもの)を埋め,その上から床土を入れる。発酵熱を利用した温床では,床温がしだいに低下していくが,電熱温床では床温をいつまでも一定に保つことができる。… ※「温床線」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
