| 为研究以农作物秸秆为墙体材料的日光温室(以下称秸秆块墙体日光温室)的保温蓄热性能,以秸秆块墙体日光温室为研究对象,以空心砖墙体日光温室为对照,监测了两种墙体材料温室中空气、墙体、土壤和温室各界面温度变化,分析了两种墙体材料日光温室的保温蓄热性能。结果表明:秸秆块墙体在晴天和阴天时均具有很好的保温性能,空心砖墙体晴天夜间时散失的热量是秸秆块墙体的1.5倍,阴天夜间时散失的热量是秸秆块墙体的1.3倍;秸秆块和空心砖墙体日光温室阴天时室内最低气温分别为5.4 ℃和5.8 ℃,晴天时室内最低气温为6.0 ℃和7.4 ℃;秸秆块墙体温室中40 cm以上土壤平均温度(14.00±2.61)℃高于空心砖墙体温室(13.55±1.73)℃。温室结构中各界面表面温度主要受太阳辐射强度的影响,秸秆块墙体温室中10 cm以上土壤层和空气的蓄热量比空心砖墙体温室中的大,秸秆块墙体的蓄热量比空心砖墙体的蓄热量小。 |

| The purpose of this paper was to analysis the heat-insulating performance of solar greenhouse with straw-bale. A hollow brick wall was also evaluated as a control. The air temperature, the temperature at indoor and outdoor wall surface, at 5 cm depth of wall, soil temperature at different depth, and interface temperature were monitored and discussed. The results showed that the straw-bale wall has better thermal insulation properties than the hollow brick wall on both sunny and cloudy days. The dispersing heat in the hollow brick wall was 1.5 times greater than that in the straw-bale wall at night on sunny day, and 1.3 times greater than that in straw-bale wall at night on cloudy day. The lowest air temperature in straw-bale wall and hollow brick wall solar greenhouse were 5.4 ℃ and 5.8 ℃ on cloudy day, and 6.0 ℃ and 7.4 ℃ on sunny day, respectively. The air temperature in the hollow brick wall was higher than that in the straw-bale wall because of lower heat-storage performance of the hollow brick. The average soil temperature in straw-bale wall solar greenhouse(14.00±2.61)℃ was higher than that in the hollow brick wall(13.55±1.73)℃。 All the interface temperatures were influenced by the solar radiation intensity. The heat was stored in the soil and air in straw-bale wall solar greenhouse. The thermal storage ability of soil(above 10 cm) and air in straw-bale wall greenhouse was larger than that in hollow brick wall, while the thermal storage ability of straw-bale wall greenhouse was smaller than that of the hollow brick wall. The present paper provides the advantages and disadvantages of these two wall types of solar greenhouse, which would help improve the technique of straw-bale wall solar greenhouse. |
