摘要
从日光温室内部光环境变化入手,以满足作物获得充足光照为目标,提出以保证冬至日正午前后4 h内,太阳光对温室前屋面透过后的辐射照度衰减率不超过2%,以及保证栽培区最后一排作物的冠层全天受到太阳照射为条件,建立了一套日光温室总体尺寸的取值方法。并与典型区域的日光温室建造规范进行比对。结果表明:该方法具有较高的可信度,能够为科学指导我国日光温室规范化建设提供理论参考。
This research based on internal light environment change of solar greenhouse,using fulfilling plants illumination demands as aim,developing ensuring the irradiance decay rates less than 2% after sunlight through the greenhouse roof in 4 h around noon on winter solstice and the last row plant canopy receiving sunlight all day in cultivated area as limitation conditions,established a kind of determination method for solar greenhouse integral sizes.By comparing with construction criterion of solar greenhouse in typical regions,the results showed that this method had high credibility and can provide theoretical reference for scientifically guiding standardization construction of solar greenhouse in China.
