Research on Test of Sunlight Greenhouse Illumination Environment

Article Preview

Abstract:

This paper uses total radiation instrument and scattered radiation instruments to test illumination irradiance in the center point of sunshine greenhouse, and compares the test data with the software model predicted data, the results show that: the radiation of fine day indoor sunshine greenhouse is generally larger than that in cloudy. The average values in fine day of outdoor observation value, outdoor simulation value, indoor observation value, indoor simulation value are 347.6, 292.3, 153.8 and 151.7, while that in cloudy day are 261.1, 262.7, 110.2and 123.9. The trend of total indoor radiation simulation value is consistent with the observation value.
