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 ana lyzed the wall surface temperature root environment temperature indoor and outdoor temperature and the difference in the yield and quality inds 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 tempera ture 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 1 396 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 im proving the greenhouse heat environment and improving the quality and yield of strawberry Key words solar greenhouse wall temperature strawberry
