PROBLEM TO BE SOLVED: To provide a device capable of reducing and decreasing time and effort and a cost of setting work and removing work, and eliminating a running cost such as electricity rate, and further capable of not only preventing a ground temperature from drastically decreasing in a winter season, but also suppressing a ground temperature from rising in a summer season adversely.SOLUTION: A panel-like solar heat using plant cultivation assist device to be installed vertically to the ground of a cultivation place 2 of a plant 1 is formed by superposing a heat conduction surface portion 3 touching soil of the cultivation place 2, a plate-like heat storage material 4 to be superposed on and attached closely to the heat conduction surface portion 3, and a thermal insulation portion 5 insulating the outer peripheral surface excluding the side of the heat conduction surface portion 3 of the heat storage material 4. The heat storage material 4 is detachably installed on the thermal insulation portion 5. A pushing portion 8 into soil is formed on the lower part of the thermal insulation portion 5.COPYRIGHT: (C)2014,JPO&INPIT【課題】 設置作業、撤去作業の手間隙やコストを軽減化、低減化でき、また電気料金等のランニングコストを一掃でき、更には冬季に地温が極端に低下することを防止できるだけではなく、夏季は逆に地温が上昇するのを抑えることができるようにする。【解決手段】 植物1の栽培箇所2に地面に対して縦向きに設置するパネル状の太陽熱利用の植物栽培用補助器である。栽培箇所2の土に接する熱伝導面部3と、この熱伝導面部3に重ね合わして密着させる板状の蓄熱材4と、この蓄熱材4の熱伝導面部3の側を除いた外周面を断熱する断熱部5とを重ね合わして形成する。蓄熱材4を断熱部5に着脱自在に設ける。断熱部5の下部に土への押し込み部8を形成する。【選択図】 図1
