The invention belongs to the field of artificial environment control of constant-temperature and constant-humidity laboratories, phytotrons and the like and relates to a field phytotron temperature control system and temperature control method. The system comprises a constant-temperature water tank, a water chilling unit, a mold temperature controller, a first air heat exchanger and a second air heat exchanger; a water outlet of the constant-temperature water tank is communicated with a water inlet of the water chilling unit through a water pipe. By means of the design, the temperature of a phytotron can be accurately controlled, the crop growth climate environment under the natural condition can be simulated according to experiment requirements, and the problems of large air temperature control error, large indoor temperature uniformity error, large environment humidity change and high energy consumption of a phytotron are solved. 本发明涉及恒温恒湿试验室、人工气候室等人工环境控制领域，具体地说，涉及一种野外人工气候室温度控制系统及温度控制方法，包括恒温水箱、冷水机组、模温机、空气换热
