摘　　要：系统地分析了北京-青海科技合作示范温室的冬季性能特点,结果为冬季温室内最低温为6.5℃,持续时间为1~3 d,大多数时间温度都在20℃左右;湿度每天0：00~6：00变化不大,都在79.8%~84.6%,而且湿度和温度呈反相关;最低露点温度出现在早上6：00,露点温度和气温呈正相关;地表下10 cm深处的地温基本保持在9.5~21.7℃;冬季晴天温室内光强通常在20~30 klx,最大可达到42 klx。Winter function features of Beijing-Qinghai science and technology cooperation gresshouse were analyzed.The results showed that minimum temperature was 6.5℃ in gresshouse of winter,the continuous days were 1-3 days.The temperature was kept at 20℃ most time during a day.The air humidity had little change in 0：00-6：00 of every day,generally kept between 79.8%-84.6%.There was an inverse correlation between air humidity and air temperature.The minimum dew point temperature was in 6：00 of every day.There was an positive correlation between dew point temperature and air temperature.The ground temperature was kept between 9.5℃-21.7℃ in the depth of 10 cm.The light intensity was at 20-30 klx in gresshouse of winter,the maximum light intensity could reach 42 klx.
