摘　　要：以红颜草莓为试材,比较PO膜和PE膜两种不同覆盖材料对越冬日光温室内温度、湿度、光照等温室环境条件及草莓产量、品质的影响。结果表明:相比PE膜,采用PO膜作为覆盖材料的越冬日光温室内平均温度提高1℃左右,保温性更好,湿度更适宜,光照效果更好;草莓产量提高23.27%,坏果率降低,果实可溶性固形物、VC含量、糖酸比均有明显提高,口感更好。Taking strawberry ＇ Hongyan＇ as test material, this study compared the effects of PO and PE film covering materials on greenhouse environment conditions, including temperature, humidity, illumination and strawberry yield and quality in over-winter sunlight greenhouse. The results showed that using PO film the average temperature of greenhouse was about 1℃ higher than that using PE film. The heat preservation was better, humidity was suitable, and lightening effect was also good in greenhouse using PO film. Besides, the strawberry yield increased by 23.27%, rotten fruit percentage was reduced , contents of soluble solids and VC, sugar/acid ratio were all increased obviously, and the strawberry tasted even better.
