PROBLEM TO BE SOLVED: To provide a plant growth-accelerating apparatus capable of accelerating the growth of a plant with energy saving to reduce its running cost.SOLUTION: According to the present invention, there is provided a plant growth-accelerating apparatus that applies a current for accelerating the growth of a plant on only electrodes where the root of the plant resides. Specifically, it is performed by applying a voltage for detecting the presence or absence of a root 101a while switching electrodes 105 divided into a plurality of pairs, and measuring the current between the electrodes.SELECTED DRAWING: Figure 1【課題】 省エネルギーで成長促進を行うことができ、ランニングコストの低減が可能な植物成長促進装置及び方法を提供する。【解決手段】 複数対に分割された電極１０５を切替えながら、根１０１ａの有無を検出するための電圧を印加し、電極間の電流を計測することにより、根が存在する電極間のみ植物成長促進用の電圧を印加する。【選択図】図１
