摘要:

为改善传统日光温室抵御自然灾害能力差、土壤利用率低等问题,提出一种新型装配式异质复合墙体日光温室。该温室由骨架构成承重结构,墙体由蓄热层和保温层构成,厚度仅30 cm,实现土地资源的高效利用。本研究主要对温室冬季应用效果进行测试与分析,分别在温室内外布置31个温度、1个太阳辐照量和1个室外风速测点。结果表明:连续阴天状况下,温室内日最低空气温度范围为6.5~8.9℃;土壤日最低温度范围为15.3~18.2℃;温室墙体内表面最低温度范围为6.5~9.6℃;均维持在番茄适宜生长温度范围内。同时对温室连续1个月的室内温度进行分析,无低于番茄最低耐受温度的情况出现。所设计温室在连续阴天的不利状况下具有较好的保温和蓄热性能,可实现番茄的越冬生产。本研究可为装配式日光温室的建造和发展及新型复合墙体材料的选择提供一定的理论依据。

Abstract:

In order to solve the problems of traditional solar greenhouses such as poor resistance to natural disasters and low soil utilization efficiency, a new type of prefabricated heterogeneous composite wall solar greenhouse is proposed. The greenhouse is composed of a bone structure forming a load-bearing structure, and the wall is composed of a heat storage layer and an insulation layer, with a thickness of only 30 cm, which realizes the efficient use of land resources. This study mainly tested and analyzed the winter application effect of the greenhouse, and arranged 31 temperatures, 1 solar irradiance and 1 outdoor wind speed measurement point in the greenhouse and outdoor respectively. The results showed that under continuous cloudy days, the daily minimum air temperature range in the greenhouse was 6.5-8.9℃, the daily minimum temperature range of soil was 15.3-18.2℃, and the minimum temperature range of the internal surface of the greenhouse wall was 6.5-9.6℃, which were all maintained within the suitable growth temperature range of tomatoes. At the same time, the indoor temperature of the greenhouse was analyzed continuously for one month, and there was no temperature lower than the minimum tolerance temperature of tomatoes. The designed greenhouse has good thermal insulation and heat storage properties under the unfavorable condition of continuous cloudy days, which can realize the overwintering production of tomatoes. This study can provide a certain theoretical basis for the construction and development of prefabricated solar greenhouses and the selection of new composite wall materials.
