对山东普遍用于黄瓜等冬季蔬菜种植的日光温室内温度和光照进行测定，结果表明：日光温室虽然有很好的保温采光性能，但在寒冷季节内，日光温室内的温光条件仍满足不了黄瓜等作物正常生长的需要。日光温室内的温度条件在很大程度上受外界气温的影响，两者呈双曲线型相关。温室的温光调节不能仅根据作物正常生长的需要，日光温室内夜间所能维持的温度也是调节的重要依据。为防止夜间温度过低，白天宜高温管理以蓄积热量，早揭草苫，以增加温室截获光能时间。
The temperature and light in sunlight greenhouse which are generally used for planting winter vegetables such as cucumber in Shandong were measured. The results showed that although the sunlight greenhouse had a good light and heat insulation performance, the temperature and light conditions in solar greenhouse could not be satisfied in the cold season Cucumber and other crops need to grow normally. The temperature conditions in the solar greenhouse are greatly affected by the outside air temperature, and the two are hyperbola-related. Greenhouse temperature and light regulation can not only be based on the needs of normal crop growth, solar greenhouse temperature can be maintained at night is an important basis for regulation. In order to prevent the night temperature is too low, the day should be high temperature management to accumulate heat, as soon as possible, to increase the greenhouse intercepted light time.
