摘要: 为量化不同天气状况下日光温室气温与外界气象条件的关系,基于日照百分率法划分了天气状况,分析了不同天气状况下温室内气温的变化规律;通过构建回归方程,研究了温室气温与外界气象条件的量化关系。结果表明,晴天、多云、阴天下,春秋季温室内气温最大值分别出现在12:00、12:00和13:00,最小值分别出现在6:00、7:00和7:00,冬季则分别出现在13:00、13:00和14:00,最小值均出现在8:00;与温室外对比,温室内升温时间较室外推后1 h左右,降温时间则变化不一,春秋季较室外提前2~3 h,冬季则提前1~2 h;当连阴天数低于3 d时,春秋季温室外最低气温每降低1 ℃,晴天、多云、阴天下温室内最低气温分别降低0.25、0.32和0.32 ℃,冬季则分别降低0.34、0.42和0.37 ℃;当外界连阴天天数超过3 d时,连阴天数每增加1 d,春秋季温室内最低气温约降低0.33 ℃,冬季则降低0.41 ℃,室外最低气温每降低1 ℃,春秋季、冬季温室内最低气温均约降低0.34 ℃。

Abstract: In order to quantify the relationship between solar greenhouse temperature and external meteorological conditions under different weather conditions, the weather conditions were analysised based on sunshine percentage method, and the changing rules of temperature in greenhouse under different weather conditions were analyzed. The quantitative relationships between temperature in greenhouse and external meteorological conditions were studied by establishing a regression equation. The results showed that on sunny, cloudy and full-cloudy days, the maximum temperature appeared at 12:00, 12:00 and 13:00 in spring and autumn, and the minimum temperature appeared at 6:00, 7:00 and 7:00 in greenhouse. In winter, the maximum temperature appeared at 13:00, 13:00 and 14:00, and the minimum temperature all appeared at 8:00. The temperature rising time in greenhouse was about 1 h later than outside, and the cooling time varied, with 2~3 hours earlier than outside in spring and autumn, and 1~2 hours earlier in winter. When the number of consecutive overcast days was less than 3 days, for every 1 ℃ decrease in outdside minimum temperature in spring and autumn, the minimum temperature in greenhouse would decrease by about 0.25, 0.32 and 0.32 ℃ on sunny, cloudy, and full-cloudy days, and by about 0.34, 0.42 and 0.37 ℃ in winter. When the number of overcast days exceeds 3 days, for every 1 days of continuous overcast days, the minimum temperature in greenhouse would decrease by 0.33 ℃ in spring and autumn, and by 0.41 ℃ in winter. For every 1 ℃ decrease in the outdside minimum temperature, the minimum temperature in greenhouse would decrease by about 0.34 ℃.
