In order to more comprehensively and scientifically grasp the change rule of indoor environment of double-film solar greenhouse in spring season,this paper takes double-film solar greenhouse as the research object,analyzes the time-varying law and characteristics of indoor heat and humidity environment of double-film solar greenhouse under spring conditions on a typical day by real-time monitoring of indoor and outdoor environments.The results showed that under spring conditions,the maximum in-door temperature rise reached 23.91℃on a sunny day,10.51℃on a cloudy day,and 18.97℃on a cloudy day.The indoor light intensity and temperature change trends were similar on sunny and cloudy days,while humidity showed an opposite change pattern to light intensity.The range of humidity changes on cloudy days was small,with the maximum humidity of 91.41%,the minimum humidity of 76.17%,and the average daily humidity of 87.67%.
