摘　　要：以冬枣为试材,在常温条件下(18～20℃),研究硅窗和打孔包装对冬枣的贮藏保鲜效果。定期统计其转红指数、腐烂指数和软果率,同时测定硬度、Vc、总糖、总酸及乙醇含量等指标的变化,分析表明:硅窗和打孔包装对冬枣的保鲜效果均优于对照组,打孔包装效果明显优于硅窗组,试验条件下以打2个孔保鲜效果最佳。Experiment was conducted with the fruit of winter jujube cultivar for studying the storage quality by using silicon windows and punch packaging under normal temperature（18 ～20 ℃）.The turning red index,de-caying index and soft fruit ratio were examined regularly.At the same time,the hardness,ascorbic acid,total sugar,total acid and ethanol content were determined.The result shows that： silicon window and drilling package were,for storage,better than the comparison group.Packing punch group was better than silicon window group obviously.Punching two holes made the best results under the experimental conditions.
