以华南地区主要类型温室全开启温室和薄膜温室为研究对象,采用温室环境传感器检测方法,研究并分析了2种温室温度和光照环境特征。结果表明:无论晴天还是阴天,全开启温室内的温度稳定性均优于薄膜温室,但是冬季室外最高温度为28.3℃时,2种温室内最高温度均超过35℃,超过作物的生理需求要开启通风设备;2种温室内光环境研究结果表明,薄膜温室的采光性能和光照分布均匀性均优于全开启温室,阴天全开启温室采光率仅为21.9%;温室遮阳性能研究表明,设置遮阳系统对温室内光照调节性能影响显著。
Taking greenhouse and thin film greenhouse as main research objects in the main types of greenhouses in South China, two kinds of greenhouse temperature and light environment characteristics were studied and analyzed by using greenhouse environmental sensor detection method. The results showed that the temperature stability in the fully open greenhouse was better than that in the thin film greenhouse in both sunny and cloudy days. However, when the outdoor maximum temperature was 28.3 ℃ in winter, the maximum temperature in both greenhouse exceeded 35 ℃, which exceeded the physiological needs of crops The ventilation equipment was turned on. The results of light environment in the two greenhouses showed that the light harvesting performance and light uniformity of the greenhouse were better than that of the full-open greenhouse. The light-harvest rate was only 21.9% Sunshade system on the greenhouse light regulation performance significantly.
