以宁夏贺兰园艺产业园日光温室为研究对象,以日光温室后墙裸墙为对照,研究了反光幕、黑色膜不同后墙张挂材料处理对日光温室室内光照强度、墙体表面温度及湿度等室内环境的影响,以期为日光温室环境调控提供理论依据。结果表明:水平方向反光幕区光照强度最大,平均高于其它2个区12.7%~15.4%;垂直方向与水平方向相似,三者差异显著;晴天黑色膜区墙体表面温度最高,平均高于其它2个区1.6~7.2℃;阴天受光照影响,裸墙区墙体表面温度最高,平均高于其它2个区1.3~4.5℃;晴天裸墙区墙体表面平均湿度最高,高于其它2个区9.5%~16.3%;阴天黑色膜区平均湿度高于其它2个区6.3%~10.4%;不同处理下墙体表面平均温度进入冬季后逐渐降低,尤其夜间规律明显,黑色膜区温度始终高于其它2个区。
Taking the greenhouse of Ningxia Helan Horticultural Industry Park as the research object and the nude wall of the solar greenhouse as the contrast, this paper studied the effects of the reflective curtain and the different materials of the back wall of the black film on the indoor light intensity, the surface temperature and the humidity of the greenhouse Indoor environment, in order to provide a theoretical basis for the regulation of sunlight greenhouse environment. The results showed that the light intensity of the horizontal reflective curtain was the highest, averaging 12.7% ~ 15.4% higher than that of the other two regions; the vertical direction was similar with the horizontal direction, and the difference was significant; The other two areas of 1.6 ~ 7.2 ℃; cloudy by the light of the impact, the naked wall area wall surface temperature is highest, an average of 1.3 ~ 4.5 ℃ higher than the other two areas; sunny naked wall area wall surface average humidity highest, higher than the other The average humidity of the black film area in cloudy day was 6.3% ~ 10.4% higher than that of the other two areas. The average surface temperature of the wall surface gradually decreased after entering the winter in different treatments, especially at night. The black film area The temperature is always higher than the other 2 zones.
