PROBLEM TO BE SOLVED: To provide an agricultural linked greenhouse that effectively exposes farm products in the linked greenhouse to sunlight from the roof of the linked greenhouse, without wasting most of the sunlight as shade parts, while increasing the time of exposure most precious for cultivated plants, and making uniform the amount of light received by the different farm products in greenhouses, thereby increasing and homogenizing the quality of farm products in the greenhouses, and preventing diseases, etc., for high yields and excellent economic properties.SOLUTION: In an agricultural linked greenhouse 1, an attic Y and a cultivation chamber S in each greenhouse are separated from each other by a heat-insulation curtain 8 that opens and closes, and a gutter 6 is provided in the valley of the roof of each greenhouse M. In a predetermined position in the attic Y in each greenhouse, a reflector 9 for reflecting the sunlight received from the roof to the cultivation chamber S is disposed along the direction O of depth between the roof and the heat-insulation curtain 8.【課題】連棟ハウスの屋根から注がれた陽射しの殆ど全てを日陰部として損出させることなく、連棟ハウス内の農作物に有効に照射させるとともに、栽培植物にとって最も貴重な照射時間を長くし、且つ、各棟の農作物の受光量の均一化を図ることにより、ハウス内の農作物の品質の向上と均一化、発病の防止等を図り、収穫量が高く、経済性に優れた農業用連棟温室ハウスを提供する。【解決手段】各棟の屋根裏部屋Ｙと栽培室Ｓとを開閉する保温カーテン８で仕切ると共に、各棟Ｍの屋根の谷間に雨樋６を備えた農業用連棟温室ハウス１において、各棟の屋根裏部屋Ｙの所定の位置で、屋根から受けた太陽光を栽培室Ｓに向かって反射させる反射機９を、屋根と保温カーテン８との間で奥行き方向Ｏに配置した。【選択図】図２
