| 摘 要： | 为了进一步提高日光温室保温性能，减轻温室内低温寡照灾害发生，以苏北（徐州）番茄日光温室为研究对象，利用采集的2010年12月-2011年4月温室小气候数据及番茄发育数据，根据日光温室小气候形成的物理过程与机理，系统研究了冬春季节不同天气类型及不同叶面积指数对温室能量分配的影响。结果表明：日光温室内潜热、显热随着室内总辐射量的改变而发生变化，阴天以显热消耗为主，潜热消耗量全天低于显热；晴天日光温室内用于作物蒸腾的能量显著多于阴天，阴天室内外贯流传热消耗的能量远远多于晴天；随着叶面积指数增大，到达地面的太阳辐射减少，地面升温慢，室内空气与地表的显热交换量减少，同时室内空气与墙体的显热交换增加。本研究结果可为温室的结构优化及冬春季节日光温室管理提供科学依据。 |

| Abstract: | In order to further enhance the thermal insulation properties and reduce the frequency of low temperature and solar radiation disaster occurred in the greenhouse, the tomato sunlit-greenhouse of Xuzhou was used as research object, using the greenhouse microclimate data collected from December 2010 to April 2011, according to the physical processes and mechanism of forming sunlit-greenhouse microclimate, different weather type about winter, spring and effect of different leaf area index on greenhouse energy distribution were studied systematically. The results showed that： with indoor total radiation changing, sensible heat and latent heat changed, sensible heat consumption was the main consumption in cloudy day, latent heat consumption was less than sensible heat consumption in the whole day; the energy used as crop evapotranspiration in fine day was significantly higher than that in cloudy day, while the consumed energy of indoor and outdoor tubular heat transfer was the opposite; with leaf area index increasing, the radiation reaching the earth surface reduced, the ground heating was slow, the exchanging quantity between indoor air and sensible heat of earth surface reduced, while the exchanging quantity between indoor air and sensible heat of wall increased. The results could provide a scientific basis for greenhouse structure optimization and sunlit-greenhouse management in winter and spring. |
| Keywords: | sunlit-greenhouse latent heat sensible heat heat exchange |
