为探索合理的日光温室后墙材料及结构,以普通结构温室为对照,宁夏后墙主动蓄热第三代日光温室为研究对象,测定温度、湿度、光照强度、土温和后墙热通量。结果表明,采用墙体主动蓄热技术的新型日光温室较普通结构日光温室平均提高温室内空气温度1.98℃;平均提高地温2.45℃,保温效果显著;有效增加光照强度2.28 klx;但对湿度影响不明显。该新型结构日光温室在保温性、透光性等方面均优于普通日光温室,且具有骨架结实、使用寿命长等优点。
In order to obtain a reasonable structure of wall in solar greenhouse,taking the normal solar greenhouse as contrast,we detected the air temperature,air humidity,soil temperature,sunlight intensity and heat storage capacity of the active storage wall in the third generation greenhouse. The results showed that,compared with the normal solar greenhouse,in the solar greenhouse with active storage wall,the average air temperature and ground temperature increased by 1.98℃ and 2.45℃,respectively,the insulation effect was obvious; the effective light intensity increased by 2.28 klx;but the humidity change was not obvious. The new structure of solar greenhouse in the heat preservation,light transmittance and other aspects were better than those in normal solar greenhouse,and had a strong frame and long life,etc,which had a good application prospect.
