摘要
为了深入理解农村日光温室生产与气象要素的关系,并提供基层设施农业气象服务关键的科技支撑,基于锦州日光温室观测数据,分析了日光温室气温的旬变化特征和日变化特征,及其与外界气温和长波辐射的关系。结果表明:非生长季日光温室旬平均气温不呈显著的变化规律,日平均气温呈现显著的变化规律,最高为午后2点,最低为早晨8点。日光温室气温变化主要受温室地面长波辐射和外界气温影响,非生长季气温显著升高,可能有利于设施农业的发展。日照时数减少,导致温室内气温下降,但就近60年的变化程度,日照时数的变化程度不足以限制农村设施农业日光温室的发展。因此,短期的低温寡照将成为日光温室发展的关键因子。
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.
