对棚型结构、建筑材料不同的４种冬暖塑料大棚的透光率、棚内温度进行测定。结果表明，在冬季弱光条件下，大棚透光率与高跨比呈显著正相关，随着光照强度的增加相关性降低。棚内温度的上升速率与高跨比呈显著正相关。棚内气温与棚的保温性能、采光性能、管理措施等因素有关。
On the shed structure, building materials, four kinds of winter warm plastic shed transmittance, shed temperature was measured. The results showed that under low light conditions in winter, the light transmittance of greenhouses was significantly and positively correlated with the high-span ratio, with the decrease of light intensity. The rate of increase of shed temperature was significantly and positively correlated with the high span ratio. Shed temperature and shed insulation, lighting performance, management measures and other factors.
