三连栋日光温室的温度性能分析

Analysis of Temperature Performance of Three-span Sunlight Greenhouse

三连栋日光温室结合了日光温室和连栋温室的结构特点,实现了日光温室的连栋化和连栋温室的节能化。作者以日光温室和连栋温室为对照,对三连栋日光温室不同时段的温度性能进行了分析。结果表明：三连栋日光温室冬季和早春的温度介于连栋温室与日光温室之间,果菜较连栋温室冬季延迟采收20~30 d、早春提早定植15~20 d;夏季温度低于日光温室和连栋温室,果菜能够正常越夏栽培。

Three-span sunlight greenhouse combined with the structure characteristics of sunlight greenhouse and muhi-span greenhouse, realized multi span of sunlight greenhouse and energy-saving of multi- span greenhouse.In this trial, temperature performance of three-span sunlight greenhouse was analyzed. The results showed that temperature of three-span sunlight greenhouse was between that of sunlight greenhouse and that of multi-span greenhouse in winter and early spring, vegetabales in the three-span sun- light greenhouse Was producted 15-20 days earlier in early spring and 20-30 days later in winter than these in the multi-span greenhouse, the temperature of three-span sunlight greenhouse in summer was lower than that of sunlight greenhouse and that of multi-span greenhouse, fruit vegetables could be pro- duced normally in it in summer.
