黑龙江省温室气温与地温变化特征研究

Study on the Variation Characteristics of Air Temperature and Soil Temperature in Solar Greenhouse in Heilongjiang Province

在黑龙江省双城市进行小气候观测试验,研究了日光温室内气温和地温的变化规律及不同天气条件下室内外气温的关系。结果表明:地温波动幅度小于气温波动幅度,且地温波动滞后于气温,但二者变化趋势一致;温室内气温和地温的日最高值变化幅度大于最低值,气温日较差大于地温日较差;日照时数对温室升温具有重要作用。

The micro-climate experiment was carried out in Shuangcheng city in Heilong;iang province, the change laws of air temperature and soil temperature were studied in solar greenhouse, and the relationship between air temperature inside and outside solar greenhouse was studied under different weather conditions. The results showed that soil temperature fluctuation was smaller and later than air temperature fluctuation,but there was a synchronous trend between them. In solar greenhouse, maximum air and soil temperature fluctuation were larger minimum air and soil temperature fluctuation,daily air temperature range was larger daily soil temperature range. Sunshine duration was important in rising temperatures in solar greenhouse.
