摘 要:为研究日光温室后屋面内设反光幕对室内环境和植株的影响,在秋冬季节测定了反先幕对日光温室室内光强、温度、温度和植株株高、茎粗的影响.结果表明:后屋面张挂反光幕有补光效果,室内光照强度平均增加7%~14%,可缓解温室内南北方向光分布不均,室内温度增加1.8~7.2℃;同时温室内植株茎粗平均提高1 mm,且改善了室内植株南北高度不均的问题.因此,冬季在温室后屋面张挂反光幕,既可以补光又不影响后墙正常蓄热保证室内温度.In order to study the influence of greenhouse roof with reflective film on growth of environment and plants, the light intensity, temperature, humidity, plant height and stem diameter were measured during autumn and winter in sunlit greenhouse with the reflective film. The results showed that hanging reflective film after greenhouse roof could supplemental light and the indoor light intensity increased by 7%~14%, which eased light distribution gap of the greenhouse in the north and south,and the indoor temperature increased by 1.8~7.2℃ ;Moreover, stems diameter increased 1 mm; It could improve high inequality of indoor plants in the north and south. Therefore,hanging reflective screen after the greenhouse roof could not only supplement light but also affect the normal heat storage of back wall in winter.
