温室棚膜对室内光照强度的影响力分析

Impact Analysis of Greenhouse Membrance on Indoor Light Intensity

于2014年3月20日至4月10日连续20d,对日光节能温室和组合式内保温温室的光照强度进行连续测定分析,研究了温室棚膜对光照强度的影响力以及规律性变化。结果表明:通过分析38种常见瓜、菜品种的光饱和点,确定双膜结构的组合式保温温室的室内光照强度完全可满足正常的农业生产。

Continuous 20 days measurement analysis on light intensity was conducted to the energy-saving solar greenhouse and composite insulation greenhouse from March 20 th to April 10 th,effect of greenhouse films on the influence of light intensity regularity change were studied.The results showed that,through analyzing light saturation point of 38 kinds of common melons,vegetables varieties,indoor light intensity of double membrane structure of composite insulation greenhouse could completely meet normal agricultural production.
