Abstract

The invention provides an experimental device for studying the influence of high temperature disaster on the blocking of wheat photosynthetic capacity, and relates to the field of wheat planting, including an experimental box, a fluorescent lamp is arranged on the top of the experimental box, a cultivation frame is slidably connected in the experimental box, and a side of the experimental box is provided. An air tank is provided with a gas circulation mechanism, the gas circulation mechanism includes an air duct fixed on the side of the test box, and an exhaust fan is rotatably connected in the air duct, and the fan blades of the exhaust fan are fixedly connected. There is a resistance wire, the air duct is communicated with the air groove on the other side of the experimental box through the air duct at the bottom of the experimental box, and the air duct is connected to the air supply and exhaust mechanism. The photosynthetic rate of wheat under temperature, thus confirming that the photosynthetic capacity of wheat is hindered under high temperature disaster conditions.

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 the blocking of wheat photosynthetic capacity. Background technique [0002] Photosynthesis is a process in which 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 more, 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 invention has the characteristics of rapid measurement, little damage, labor and financial resources saving, etc., and is suitable for breeding excel...
