为了解双膜日光温室土壤-空气换热器对周围土壤及根系的影响,对兰州市一个新建双膜日光温室和单膜普通温室进行测试对比.结果表明:阴天时,土壤温度受换热器影响较大;晴天时,土壤温度受太阳辐射影响较大.双膜日光温室的浅层土壤温度高于单膜普通温室,单膜普通温室土壤表面温度的波动幅度明显强于双膜日光温室.双膜日光温室能有效提高土壤温度,并且双膜温室的室内热环境稳定性强于单膜温室.
Experimental Study on Soil Temperature of Soil-Air Heat Exchanger in Double-film Solar Greenhouse
In order to understand the effects of the soil-air heat exchanger on the surrounding soil and roots of a double-film solar greenhouse,a new double-film solar greenhouse and a single-film conventional greenhouse was compared in Lanzhou.The results show that heat exchanger affects soil temperature on cloudy days.On sunny days,soil temperature is greatly influenced by solar radiation.The shallow soil temperature of the double-film solar greenhouse is higher than that of the single-film conventional greenhouse,and the fluctuation range of soil surface temperature of single-film conventional greenhouse is obviously stronger than that of the double-film solar greenhouse.Double-film solar greenhouse can effectively increase the soil temperature,and the indoor thermal environment stability of the double-film greenhouse is stronger than that of the single-film greenhouse.
