AI Technical Summary
Technical Problem
Existing farmland high-temperature stress control systems have uncontrollable temperature rise rates under different weather conditions and consume a lot of energy, which cannot meet the experimental needs under multiple weather conditions.
Method used
By combining a light-transmitting film with a far-infrared radiation heater, the light-transmitting film is heated by sunlight on sunny days and by the far-infrared radiation heater on cloudy or rainy days. The film can be unfolded and folded by moving the traction frame and the fixing frame, thus saving energy.
Benefits of technology
It enables flexible temperature adjustment under different weather conditions, saves energy, is highly adaptable, and occupies little space.

Abstract
The utility model provides a farmland high temperature drought stress experiment control system which comprises a first vertical frame and a second vertical frame which are arranged on the two sides of a test field, a traction frame and fixing frames are further arranged between the first vertical frame and the second vertical frame, and the fixing frames are sequentially arranged between the traction frame and the second vertical frame. Light-transmitting films are arranged outside the upper portion of the traction frame and the upper portion of the fixing frame, far infrared radiation heaters are arranged on the traction frame and the fixing frame, moving wheels are arranged at the bottom end of the traction frame and the bottom end of the fixing frame, and the traction frame is used for driving the fixing frame to move and driving the light-transmitting films to be folded or unfolded. The light-transmitting films are arranged at the top ends of the first vertical frame and the second vertical frame, the far infrared radiation heaters are installed on the traction frame and the fixing frame, sunlight can be used for warming in sunny days, the light-transmitting films also play a role in shielding rain, the far infrared radiation heaters can be used for warming in cloudy and rainy days, different warming control requirements of farmlands can be met, and the temperature of the farmlands can be increased. And the applicability is good.
