The present invention without causing out loss almost all of the sunlight that poured from the Row house roof as a shade part, along with the order to effectively irradiated to the crop in the semi-detached house, the most valuable irradiation for cultivated plants longer time, and, by made uniform in the amount of received light for each building crops, improve the uniformity of quality of the crop in the house, it aims to prevent the onset or the like, high yield, good economics to provide agricultural Row greenhouse House. In agricultural Row greenhouse house with a rain gutter 6 in the valley of the roof of each building M along with the partition in the heat insulation curtain 8 for opening and closing the A and attic Y of each building and the cultivation chamber S, in place of the attic Y of each building, a reflection device 9 for reflecting towards the cultivating chamber S sunlight received from the roof and placed in the depth direction between the roof and the heat insulating curtain 8.FIELD 2【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に配置した。【選択図】図2
