摘要
利用2012年4月—2013年5月大洼日光温室内外小气候观测资料,分析不同天气条件下温室内外小气候变化特征及温湿度效应。结果表明：晴天、多云、阴天和降水时温室内最高气温为28.9～29.6、23.8～27.5、14.6～22.9和10.3～21.4℃,比温室外高5.5～33.5℃;晴天、多云、阴天和降水时温室内最低气温为5.3～9.0、6.8～9.9、5.8～11.0和4.0～7.9℃,比温室外高2.5～20.8℃。4种天气条件下温室内最低相对湿度为44.8%～67.7%、59.4%～78.3%、74.7%～91.8%和82.4%～99.9%,比温室外高0.8%～27.1%;温室内最大相对湿度比温室外略高或持平。温室内外温差在白天尤其中午前后较大,在夜间较小;而湿度差在夜晚或凌晨较大,在白天较小或无差异。晴天增温增湿效果高于其他天气条件,冬季增温增湿效果高于春季和秋季。温室内总辐射日出前和日落后为0W·m-2,最大值出现在正午前后。
Using the microclimate data of inside and outside greenhouse in Dawa of Liaoning Province from April 2012 to May 2013, this paper analyzed the characteristics of microclimate and temperature and humidity effects of inside and outside greenhouse under different weather conditions. The results showed that the maximum temperatures inside greenhouse on sunny, cloudy, overcast and rainy days were 28.9-29.6, 23.8-27.5, 14.6-22.9 and 10.3-21.4 ℃, being 5.5-33.5 ℃ higher than that of outside. Under the abovementioned weather conditions, the minimum temperatures inside greenhouse were 5.3-9.0, 6.8-9.9, 5.8-11.0 and 4.0-7.9 ℃, respectively, being 2.5-20.8 ℃ higher than that of outside, and the minimum humidity in- side greenhouse were 44. 8% -67.7% , 59.4% -78.3% , 74. 7% -91. 8% and 82.4% - 99.9% , respectively, being 0.8% -27.1% higher than that of outside, while the maximum hu- midity inside was slightly higher or equal to outside. The temperature difference between inside and outside greenhouse was larger at daytime, especially around noon, but smaller at nighttime. The humidity difference was lager at night, less or no difference at daytime. The warmer and wet- ter effects were more often observed on sunny days than under other weather conditions and in winter than in autumn and spring. The total solar radiation was 0 W · m-2 before sunrise and after sunset, and the maximum value appeared around noon.
