摘　　要：为了研究不同年型下日光温室内小气候的差异及对蔬菜生长发育需要的满足情况,实现对日光温室有目的地科学管理,基于偏暖年型和偏冷年型下日光温室内小气候资料,结合黄瓜生长发育所需要的气象条件,对比分析2种年型下日光温室内在温度、光照和空气相对湿度方面的差异。结果表明,偏暖年型下日光温室内的适宜温度出现的时间较长,日照相对充足,但发生热害的风险更大,温室管理应重点预防热害;偏冷年型下日光温室内的热量远不能满足黄瓜生长发育需要,尤其是冬季,存在发生冷害或冻害的风险,温室管理应以预防低温冷害或冻害为重点。In order to research the microclimate differences and the conditions the microclimate which meet the need of vegetable growth in sunlight greenhouse in different years, to realize objective management in sunlight greenhouse, based on the microclimate data in sunlight greenhouse in the warm and cold years, combined with the meteorological conditions needed by the growth of cucumber, the author analyzed the microclimate differences, about temperature, sunlight and air relative humidity, in sunlight greenhouse between the warm year and the cold year. The results showed that： in sunlight greenhouse, the temperature was more suitable for the growth of cucumber in the warm year, and the sunshine was relatively abundant, while the thermal hazard risk was greater, so the management in sunlight greenhouse should focus on the prevention of thermal hazard; the heat in sunlight greenhouse in the cold year could not meet the needs of growth of cucumber, especially in winter. There was chilling or freezing injury risk in the cold year, so the management in sunlight greenhouse should focus in the prevention of chilling or freezing injury.
