The present invention while improving sunshine in the central portion of the pot plant to the (growing point), flower buds can be Hoko light having a peak in the desired area of the central portion as needed (growing point) Differentiation to provide a promotion for the auxiliary light equipment. A pressing portion 2 to push the A stem 12 of the leaf 11 extending from the periphery of the growing point 9 of tubers 8 radially, is fixed to the pressing unit 2, and at the center side of the pressing part 2 and at least one of the LED light source 3 emits light having a peak between a wavelength of 390~470nm toward the vertically lower side, and at least two leg portions 4, 4 which protrude vertically downward side of the pressing part 2 having a pressing portion 2 is of a looped, characterized in that it comprises a cut (5) for dividing the pressing portion 2 at least 2 or more.FIELD 2【課題】鉢植え植物の中央部(生長点)への日照を改善しつつ、必要に応じて中央部(生長点)の所望領域にピークを有する光を補光することができる花芽分化促進用補光装置を提供する。【解決手段】塊茎8の生長点9の周囲から伸びる葉11の茎12を放射状に押し広げる押圧部2と、この押圧部2に固設され、押圧部2の中央側でかつ鉛直下方側に向かって波長390~470nmの間にピークを有する光を発光する少なくとも1のLED光源3と、押圧部2の鉛直下方側に突設される少なくとも2本の脚部4,4とを有し、押圧部2は、ループ状をなし、押圧部2を少なくとも2以上に分割する切れ目5を備えていることを特徴とする。【選択図】図2
