In order to create a suitable thermal and humidity environment for crop growth in the solar greenhouse, a novel polystyrene foam modular double film solar greenhouse was designed and constructed. The double film solar greenhouse wall adopted polystyrene foam modules, with internal and external supporting frameworks and covering double-layer film, forming a thermal buffer zone which can collect and store solar energy passively. We tested indoor environmental factors variation of the double film solar greenhouse and the ordinary single film greenhouse in winter. Compared with the single film solar greenhouse, results show that the double film solar greenhouse effectively improves the indoor air, soil temperature and CO₂ concentration, and reduces the indoor air humidity and soil humidity. The value of environmental factors of light, heat, water and air system in double film greenhouse is more stable than that in single film ordinary greenhouse. It provides a theoretical basis for the construction of double film solar greenhouse and indoor environment regulation.

为了在日光温室内为作物生长创造适宜的热湿环境，设计建造了一种新型聚苯乙烯泡沫模块化双膜日光温室。双膜日光温室墙体采用聚苯乙烯泡沫模块，内外支撑框架，覆盖双层膜，形成被动收集和储存太阳能的热缓冲区。我们测试了双膜日光温室和普通单膜温室在冬季室内环境因素的变化。结果表明，与单膜日光温室相比，双膜日光温室有效地改善了室内空气、土壤温度和CO _{2 。}浓度，降低室内空气湿度和土壤湿度。双膜温室的光、热、水、气系统环境因子值比单膜普通温室更稳定。为双膜日光温室的建设和室内环境调控提供了理论依据。
