Study on Microclimate of Winter and Spring Pepper Greenhouses in Yongfeng County

To improve pertinency and practicalness of meteorological services for greenhouse pepper,the correlation among temperature variation inside and outside greenhouse,minimum daily air temperature within greenhouse,and other factors in 3 weather patterns(sunny,cloudy,overcast) was analyzed on the basis of the observation data of meteorological elements,such as inside and outside greenhouse temperature,soil temperature in Yongfeng County,Ji'an City.The results showed that air temperature difference inside greenhouse was greater than that outside greenhouse,range of daily air temperature variation inside and outside greenhouse was greater in sunny and cloudy days than in overcast days,maximum air temperature inside and outside greenhouse was sunny days cloudy days overcast,minimum air temperature overcastcloudy days sunny days.Minimum air temperature inside greenhouse,minimum air temperature outside greenhouse,minimum soil temperature outside greenhouse(0 cm),and minimum soil temperature outside greenhouse(20 cm) showed extremely significant correlation,and no correlation with sunshine houres.
