| 摘 要： | 采用多层覆盖是冬季温室保温的一个重要手段，本试验通过在温室四周增加保温幕围护、顶部覆盖双层保温幕和搭建小棚等保温措施，对其在冬季夜间的保温效果进行了研究。结果表明，通过在温室设置四周保温幕和顶部双层保温幕可提高室内温度2～5?℃|在温室内采用四周保温幕、顶部双层保温幕覆盖并搭建小棚能使温室小棚内温度提高8.5?℃以上，在温室四周增加保温幕围护不仅可以提升温室内温度，还可以减少温室在冬季的边际效应。

| Abstract: | Multi-layer covers was an important method of heat preservation for greenhouse in winter．Enclosures，top double thermal screens and covers are increasingly used around greenhouses, in order to study the effects of insulation effect in winter night of multi-layer covers．The results show that the use of enclosures and top double thermal screens around the greenhouses can increase the indoor temperature by 2-5 ℃ and the use of enclosures，top double thermal screens and covers can increase the indoor temperature by 8.5 ℃ above．The increasing use of the thermal screen and enclosures around the greenhouse can not only increase the greenhouse temperature，but also reduce the marginal effect of greenhouse during winter． |
