Abstract

The invention provides an experimental device for studying the hindered influence of high-temperature disasters on the photosynthetic capacity of wheat, and relates to the field of wheat planting.The experimental device comprises an experimental box, a fluorescent lamp is arranged at the top of the experimental box, a cultivation frame is slidably connected into the experimental box, and a gas groove communicated with a gas circulation mechanism is formed in the side face of the experimental box; the gas circulation mechanism comprises an air duct fixed to the side face of the test box, an exhaust fan is rotationally connected into the air duct, a resistance wire is fixedly connected to fan blades of the exhaust fan, the air duct communicates with an air groove in the other side of the test box through an air pipe at the bottom of the test box, and an air supply and exhaust mechanism is connected to the air pipe. The discharged gas is detected to obtain the photosynthetic rate of the wheat at a specific temperature, thereby determining the blocking influence of the photosynthetic capacity of the wheat under the high-temperature disaster condition.

Description

technical field [0001] The invention relates to the field of wheat planting, in particular to an experimental device for studying the influence of high temperature disasters on wheat photosynthetic ability. Background technique [0002] Photosynthesis is the process that plants use light energy to absorb carbon dioxide in the air to synthesize organic matter and release oxygen. The efficiency of photosynthesis is also an indicator that determines the growth rate of plants. Photosynthesis is affected by many factors, such as moisture, carbon dioxide content in the air, Air temperature, where temperature is an important factor affecting the efficiency of photosynthesis. [0003] Patent No. CN106706579B discloses a method for screening high-temperature-resistant corn varieties using chlorophyll fluorescence technology. The PI(abs) of the maize leaves were detected after the body leaves were treated, and the high-temperature-resistant maize varieties were determined by comparis...
