PROBLEM TO BE SOLVED: To provide a carbon dioxide application facility for efficiently applying carbon dioxide to leaf portions of crops and an application method for the same, which is related to a method for growing crops in a house or the like, where a plurality of mobile culture beds or mobile water culture panels are placed on a cultivation aquarium in the house.SOLUTION: There is provided a carbon dioxide application facility and an application method for the same, where an agricultural air conditioner, an exhaust fan, and the like are installed around a cultivation aquarium placed in a house so as to flow the wind over the cultivation aquarium in a certain direction a plurality of mobile culture beds and mobile water culture panels are placed on the cultivation aquarium a carbon dioxide application port connected to a solenoid valve is installed on the windward side of the cultivation aquarium, and whereby carbon dioxide application can be controlled by opening and closing the solenoid valve the application time is controlled by a timer and excessive application is suppressed by a luminometer in a cloudy or rainy day the application can be controlled by the carbon dioxide concentration of a carbon dioxide concentration meter installed on the leeward side of the cultivation aquarium and carbon dioxide is intensively applied to leaf portions of cultivated crops by an individual control or a combination of controls, and whereby a proper amount of carbon dioxide necessary for photosynthesis can be supplied.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】本発明はハウス等で栽培用水槽に複数の移動式栽培ベッドや移動式水耕栽培用パネルを載せ作物を栽培する方法において、作物の葉部分に効率的に炭酸ガスを施用する炭酸ガス施用設備とその施用方法を提供する。【解決手段】栽培用水槽上を流れる風が一定方向に流れるようハウス内に設置した栽培用水槽の周りに農業用エアコンや換気扇等を設置し、栽培用水槽に複数の移動式栽培ベッドや移動式水耕栽培用パネルを載せ、栽培用水槽の風上側に電磁弁に接続した炭酸ガス施用口を設置し、電磁弁の開閉で炭酸ガス施用を制御できるようにし、タイマーで施用時間を、照度計で曇天や雨天時の余分な施用を抑制するようにし、栽培用水槽の風下側に設置した炭酸ガス濃度計の炭酸ガス濃度により施用を制御できるようにし、それぞれの制御を単独、または組み合わせることにより栽培作物の葉部分に集中的に炭酸ガスを施用し、光合成に必要な適正量の炭酸ガスを供給することができる炭酸ガス施用設
