| 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。

| Abstract: | 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. |
