青海省3种日光温室冬季温光性能对比

为掌握近期设计建造的新型日光温室的保温采光性能，以青海省传统砖混结构日光温室为参照，持续监测了设施蔬菜越冬生产过程中的日光温室空气温度和光照强度等环境参数，对3种日光温室的保温采光性能进行了比较和分析。结果表明:C型温室在秋冬季节保温能力较强，光照环境较好；A型温室次之；B型温室平均气温较低且在外界温度较低的情况下保温性能较差，光照环境也较差。 

Comparison on Temperature and Light Performance of Three Kinds of Solar Greenhouse in Winter in Qinghai

In order to master the thermal and lighting performance of newly designed solar greenhouse，taking traditional brick-concrete structure solar greenhouse in Qinghai province as a reference，environmental parameters such as air temperature and light intensity in the greenhouse during overwintering production of facility vegetables were continuously monitored.The thermal and lighting performance of three kinds of solar greenhouses were compared.Results showed that C-type greenhouse has better heat preservation ability in autumn and winter，and better light environment；A-type greenhouse takes second place；B-type greenhouse has worse heat preservation performance and poor light environment when the average temperature was lower and the external temperature was lower.
