PROBLEM TO BE SOLVED: To provide a method of cultivating black ginger that efficiently produces black ginger in a shortest time as much as possible by making improvement in a method of artificially cultivating black ginger, and sufficiently swelling a rootstock (tuber) to be harvested, that is, avoiding insufficient growth.SOLUTION: A cultivation method includes planting seedlings of black ginger (Kaempferia parviflora) in a medium and adjusting temperature and light in the cultivation environment of the seedlings. In the method, the temperature of the cultivation environment is adjusted to 20-25°C, and light is adjusted to a photosynthetic photon flux density of 25-35 μmolm-2s-1 for cultivation. Since the temperature and light in the cultivation environment of the seedlings are appropriately adjusted, sprouts, leaf stalks, and tubers are not infected with filamentous fungi such as mildew, and black ginger is allowed to be raised without being influenced by allelopathy.COPYRIGHT: (C)2013,JPO&INPIT【課題】黒ショウガを人工的に栽培する方法について改良を加え、収穫の対象となる根茎(塊茎)の肥大を充分なものとし、すなわち発育不良を回避して黒ショウガを可及的に短時間で効率よく生産できる栽培方法とすることである。【解決手段】黒ショウガ(Kaempferia parviflora)の幼苗を培地に植生し、この幼苗の栽培環境の温度および光を調整する栽培方法において、前記栽培環境の温度を20~25℃に調整すると共に、光を光合成光量子密度25~35μmolm-2s-1に調整して栽培することを特徴とする黒ショウガの栽培方法とする。幼苗の栽培環境の温度および光が適切に調整されることによって、新芽や葉柄および塊根にカビなどの糸状菌との感染がなく、アレロパシーの影響を受けずに黒ショウガを育成できる。【選択図】なし
