衡水地区不同跨度日光温室温度性能比较

Comparison on Temperature Performance of Solar Greenhouse With Different Span in Hengshui Area

以衡水饶阳县7.7、8.7、10.0 m 3种跨度日光温室为研究对象,采用温度动态监测统计方法,研究了温室冬季的温度性能,以期筛选适合当地越冬茄子等果菜生产的温室类型。结果表明:3种跨度温室不同温度统计指标相比,平均气温、积温、平均气温在15℃以上以及10℃以上的小时数和天数等指标均以7.7 m温室最高(或最多),其次是8.7 m温室,10.0 m温室最低(或最少)。虽然在深冬连续晴天和连续阴天2种典型天气下,3种温室的升温能力值没有显著差异,但7.7 m温室的最低温度和连续阴天的最高温度均为最高。综合分析可知,7.7 m跨度日光温室在温度性能方面表现最好,最适宜在衡水地区生产茄子等越冬果菜。

Taking the 7.7,8.7,10.0 m span solar greenhouses in Raoyang county of Hengshui as the objects,the statistical method of temperature dynamic monitoring was adopted,the temperature performance of greenhouse in winter was studied in order to select the greenhouse type suitable for the production of fruits and vegetables such as eggplant.The results showed that compared with the three different temperature statistical indicators,the average temperature,accumulated temperature,the hours and days of the average temperature above 15℃and 10℃were the highest(or the most)in 7.7 m greenhouse,followed by the 8.7 m greenhouse,the lowest(or the least)of the 10.0 m greenhouse.Although there was no significant difference in the warming capacity of the three greenhouses under two typical weather conditions,i.e.continuous sunny and cloudy days in deep winter,the lowest temperature and the highest temperature in 7.7 m greenhouse were the highest in continuous cloudy days.Comprehensive analysis showed that the 7.7 m span solar greenhouse had the best performance in temperature performance,and was the most suitable for the production of winter edible-fruit-vegetable′s,such as eggplant in Hengshui area.
