The problem addressed by the present invention is to suppress increases in facility costs while providing functions to control ambient temperature for plants. This agricultural greenhouse is provided with a greenhouse main body, a curtain (21), a window (22), and a control device (30). The greenhouse main body is covered with a transparent covering material and allows a space for raising plants to be formed in the interior thereof. The curtain (21) can move between a first position wherein external light to which the plants are exposed is reduced and a second position wherein the external light to which the plants are exposed is not reduced. A first drive device (23) moves the curtain (21) between the first position and the second position. The window (22) is movable between a closed position that does not allow air to flow between the inside and outside of the greenhouse main body and an open position that allows air to flow between the inside and outside of the greenhouse main body. A second drive device (24) moves the window (22) between the open position and the closed position. The control device (30) controls the first drive device (23) and the second drive device (24).
