摘要
对冬季日光温室内气、地温度与当时的太阳高度角之间的关系进行研究,结果表明:冬季日光温室内的旬均气、地温度与当时的太阳高度角之间存在着高度的正相关关系,即冬季日光温室内旬均气、地温度随着当时的太阳高度角的降低而规律性的下降。从9月10日到12月22日期间内,太阳高度角每降低1℃(相当于向后延续4d),则日光温室内的日均气温就下降1.0916℃,而日均10cm 地温就下降0.7464℃,气温比同期10cm 地温下降速率快46.25%。找到了太阳高度角与日光温室内气、地温度间的回归方程。
Research was conducted on interrelationship between sun altitute-angle and air and soil temperatures in solar greenhouse at different time in cold seas- on.Results showed that there were high positive relatiotships between sun altituteangle and mean decade air and soil temperanures in solar greenhouse. Mean decade temperatures of air and soil in solar greenhouse decreased regularly with the descending of the Sun altitute-angle.In the period from september 10th to December 22th when san altitute angle lowered1℃, mean temperature of air in solar greenhouse decreased 1.1℃,and mean soil temperature at 10cm depth decreased 0.75℃ Air temperature decrease speed was 46.25% faster than that of the soil's.Regression equations between sun altitute-angle and air and soil temperatures in solar greenhouse in cold season were formed.
