蓟春型与普通型日光温室温湿度特性的比较

Comparison of the Characteristics of Temperature and Humidity between Jichun Type and Common Sun-light Greenhouse

蓟春型日光温室在结构上与普通型日光温室有很大不同,为双层骨架,保温被内置于骨架之间。这种结构不仅解决了普通型日光温室保温被易受雨雪浸湿的问题。而且在采光、保温、通风等性能方面表现出许多新的特点。本试验通过对蓟春型与普通型日光温室的气温、地温和湿度等环境因子的比较,分析了蓟春型日光温室的温湿度特性,为该类型温室的改进与推广利用提供参考。测量结果表明:1月中旬,晴天蓟春型日光温室最低气温比普通型高2.5℃;阴天最低气温比普通型高1.7℃左右;最低地温无论晴天还是阴天均高于普通型0.8℃;蓟春型日光温室内空气相对湿度偏高,平均最低湿度比普通型日光温室高7.2%左右。

The structure of Jichun sun-light greenhouse which is double frame between which inner heat preservation quilt is equipped, is different from the common sun-light greenhouse. It has many new advantages on lighting, heat preservation and ventilation and preventing the quilt from soaking by rain or snow as well. By comparing temperature, soil temperature and humidity of Jichun type and common sunlight greenhouse,this experiment analyzed the characteristics of Jichun type sun-light greenhouse to improve and popularize. The results showed that during the mid-January, the minimum temperature of Jiehun sun-light greenhouse was 2.5 ℃ higher than that of common in clear day and was about 1.7 ℃ higher than common in overcast day. The minimum soil temperature of Jichun sun-light greenhouse was higher than that of common both clear and overcast day for 0.8 ℃. The relative humidity of Jichun type sun-light greenhouse was high and the average minimum humidity was about 7.2% higher than that of common sun-light greenhouse.
