< Topic >Supplying carbon dioxide which are discharged from the house for agriculture which cultivates the mushrooms, to the house for agriculture which cultivates the vegetable and the fruit and the flowering plant etc, as it makes photosynthesis promote, it is something which offers the house for wraparound die agriculture which held down the discharge to in the atmosphere of carbon dioxide.SolutionsThe house adjoining with the house 2 for agriculture, which cultivates 1 for agriculture which cultivates the mushrooms and the vegetable and the fruit and the flowering plant providing, installing fan 9 in house 1 for agriculture, adjoining carbon dioxide which are generated here, it is something which it tries to wrap to the house 2 for agriculture which cultivates the vegetable and the fruit and the flowering plant which it provides.< Choice figure > Drawing 2【課題】茸類を栽培する農業用ハウスから排出される二酸化炭素を、野菜や果実、花卉などを栽培する農業用ハウスに供給して、光合成を促進させると共に、二酸化炭素の大気中への排出を抑えた循環型農業用ハウスを提供するものである。【解決手段】茸類を栽培する農業用ハウス1と、野菜や果実、花卉を栽培する農業用ハウス2とを隣接して設け、農業用ハウス1にファン9を取付けて、ここで発生した二酸化炭素を、隣接して設けた野菜や果実、花卉を栽培する農業用ハウス2に循環させるようにしたものである。【選択図】 図2
