Title: Performance Comparison of Heat Preservation Between Glasshouse and Plastic Greenhouse in Spring
Abstract: Using venlo type greenhouse and plastic greenhouse as study objects,the interior diurnal variations of air temperature and soil temperature were observed on the typical weather conditions of clear day and cloudy day in spring.The results showed that the mean daily air temperature and the mean daily soil temperature inside glasshouse were higher than plastic greenhouse on clear day and cloudy day.The daily maximum air temperature,the daily minimum air temperature,and the mean daily air temperature inside glasshouse were 1.7 ℃,0.6 ℃ and 1.5 ℃ higher than plastic greenhouse on clear day,respectively.The daily maximum soil temperature,the daily minimum soil temperature,and mean daily soil temperature inside glasshouse were 1.3 ℃,0.9 ℃ and 1.1 ℃ higher than plastic greenhouse on clear day,respectively.The mean daily air temperature and the mean daily soil temperature inside glasshouse were 0.5 ℃ and 0.6 ℃ higher than plastic greenhouse on cloudy day,respectively.These results suggested that heat preservation performance of glasshouse was better than plastic greenhouse.
