Abstract:
Taking the 7.7,8.7,10.0 m span solar greenhouses in Raoyang county of Hengshui as the objects,the statistical method of temperature dynamic monitoring was adopted,the temperature performance of greenhouse in winter was studied in order to select the greenhouse type suitable for the production of fruits and vegetables such as eggplant.The results showed that compared with the three different temperature statistical indicators,the average temperature,accumulated temperature,the hours and days of the average temperature above 15 ℃ and 10 ℃ were the highest (or the most) in 7.7 m greenhouse,followed by the 8.7 m greenhouse,the lowest (or the least) of the 10.0 m greenhouse.Although there was no significant difference in the warming capacity of the three greenhouses under two typical weather conditions,i.e.continuous sunny and cloudy days in deep winter,the lowest temperature and the highest temperature in 7.7 m greenhouse were the highest in continuous cloudy days.Comprehensive analysis showed that the 7.7 m span solar greenhouse had the best performance in temperature performance,and was the most suitable for the production of winter edible-fruit-vegetable′s,such as eggplant in Hengshui area.
