摘　　要：为探究相变材料和太阳能空气集热器相结合应用于日光温室梯形墙体后对室内热环境和草莓产量、品质的影响,对主-被动式蓄热温室(Tr)和普通温室(CK)的梯形墙体的墙表面温度、根系环境温度,室内外温度、草莓的产量及品质指标进行了测试分析。结果表明,无论晴阴多云天,Tr的墙体表面温度、根际温度和室内气温均高于CK,且存在显著性差异;Tr和CK的产量分别为(1396.60±38.99)kg和(969.32±23.78)kg,与CK相比,Tr增加了44%。主-被动蓄热系统分别提高了草莓果实中的葡萄糖、果糖、蔗糖含量为33%、28%和57%,同时提高了可溶性糖17%、糖酸比75%、维生素C 30%。该研究结果可为改善温室热环境、提升草莓品质及产量提供参考。To explore the effect of the indoor thermal environment on the yield and quality of strawberry,we installed the phase change material and solar air collector in the trapezoidal north wall of solar greenhouse.We analyzed the wall surface temperature,root environment temperature,indoor and outdoor temperature and the difference in the yield and quality indexes of strawberry between trapezoidal wall of active-passive thermal storage greenhouse(abbreviated as Tr)and ordinary greenhouse(abbreviated as CK).The results showed that:the wall surface temperature,root ambient temperature and indoor temperature of Tr were significantly higher than those of CK regardless of any typical weather;the yield in the treatment group(Tr)was(1396.60±38.99)kg,which was 44%higher than that of CK(969.32±23.78)kg.Active-passive heat storage system could increase the contents of glucose,fructose and sucrose in the strawberry fruit by 33%,28%and 57%,respectively,and it also increased the contents of soluble sugar by 17%,sugar-acid ratio by 75%and vitamin C by 30%.The results of this study could provide a reference for improving the greenhouse heat environment,and improving the quality and yield of strawberry.
