PROBLEM TO BE SOLVED: To provide an agricultural temperature control system configured to increase the efficiency of energy required for heating the space for growing a plant body, the system being capable of suppressing a change in temperature due to sunlight and also adjusting the ambient humidity of the plant body.SOLUTION: According to the present invention, an agricultural temperature control system 10 comprises covers 11A and 11B, a heat supply device 12, and an adjustment device 13. The covers 11A and 11B are configured to cover a plant body 40 in a field 30. The heat supply device 12 supplies heat to the inside of a space surrounded by the covers 11A and 11B in a state where the covers 11A and 11B cover the plant body 40. The adjustment device 13 adjusts heat supplied from the heat supply device 12 to the inside of the space surrounded by the covers 11A and 11B. The covers 11A and 11B are deformable between a first state in which the plant body 40 is covered and a second state in which at least a part of the plant body 40 is exposed, and are not opened upward but opened downward in the first state.SELECTED DRAWING: Figure 1【課題】植物体を育成する空間の加熱に要するエネルギーの効率を高める構成で、太陽光による温度変化を抑制可能にし、かつ植物体の周囲湿度の調節も可能にする。【解決手段】農業用温調システム１０は、カバー１１Ａ、１１Ｂと熱供給装置１２と調節装置１３とを備える。カバー１１Ａ、１１Ｂは、圃場３０の植物体４０に被さるように構成される。熱供給装置１２は、植物体４０にカバー１１Ａ、１１Ｂが被さっている状態でカバー１１Ａ、１１Ｂが囲む空間の内部に温熱を供給する。調節装置１３は、熱供給装置１２からカバー１１Ａ、１１Ｂが囲む空間の内部に供給する温熱を調節する。カバー１１Ａ、１１Ｂは、植物体４０に被さる第１状態と、植物体４０の少なくとも一部を露出させる第２状態との間で変形可能であり、かつ第１状態において、上向きに開放されず、かつ下向きに開放されている。【選択図】図１
