冬季日光温室内光照强度弱,光照时间短,夜间温度低,易导致作物光合速率低下,生长缓慢,对作物开花、座果以及果实的发育造成严重影响。因此,改善光照条件,提高室内气温尤其是夜间室内气温,是促进作物生长,提高产量的关键。日光温室的光热性能受主体结构参数、前屋面覆盖材料、保温被性能、墙体结构等多个因子影响,需在设计、建造、环境调节等方面进行技术攻关和技术集成才
In winter, the light intensity of the greenhouse is weak, the light time is short, and the temperature is low at night, which can easily lead to the low photosynthetic rate and slow growth of the crop, which seriously affects crop flowering, fruit set and fruit development. Therefore, improving lighting conditions and increasing indoor air temperature, especially nighttime indoor air temperature, are the keys to crop growth and increase production. The solar thermal performance of the solar greenhouse is influenced by many factors, such as the structural parameters of the main body, the materials of the front roof covering, the performance of the thermal insulation, and the structure of the wall. It is necessary to carry out technical research and technical integration in terms of design, construction and environmental regulation
