Abstract Through experimental verification,the dry hot air simulation device designed and manufactured in this paper can meet the expected design requirements,which can control the temperature,humidity and wind speed artificially,and directly affect the dry and hot wind stress of wheat planted in the field to different degrees in different periods.At the same time,the changes of meteorological elements in the test environment were monitored and recorded,which was convenient for comparison observation with natural growing wheat,reducing the influence of interference factors and ensuring the accuracy of the test.By sampling the test wheat and the contra observed wheat,the thousand grain weight and yield difference of the two can be analyzed in combination with the simulated dry hot air degree,time node and duration,which provides data support for the research on the impact of dry hot air disaster and the disaster threshold caused by dry hot air disaster.
