Abstract: In order to deep understand the relationship between production in sunlight green house and meteorological factors and provide key science technology of agricultural meteorological service to sunlight green house production, based on the observation data, change characteristic of temperature in greenhouse and the relationship between it and exterior temperature, long wave radiation were analyzed. The result showed: the change trend of the ten days average temperature in greenhouse during non-growing season was not significant. The day various trend appeared ‘U’ type curve, the maximum and minimum value appeared at PM 2:00 and AM 8:00, respectively. The temperature in sunlight greenhouse was mainly affected by long wave radiation and exterior temperature. The significant rise of temperature during non-growing season could be favorable to the development of sunlight greenhouse produce. The decrease of hours of sunlight led to the temperature lower in sunlight greenhouse, however, according to the various range during later 60 years, the change extent of sunlight hours was not enough to limit the development of sunlight greenhouse produce in countryside. Therefore, the short-term low temperature and less sunlight was mainly control factors for sunlight greenhouse produce.
