摘　　要：为了探究金兰柚最佳套袋时间,为金兰柚套袋技术生产应用提供一定理论基础,以金兰柚果实为研究材料,比较了套袋前后袋内温度、湿度、光照强度的变化及对金兰柚果实内外品质的影响。结果表明,套袋后袋内温度升高,湿度增大,光照强度减弱;套袋处理可以改善果面色泽,增加果皮厚度,降低果实总糖含量及可滴定酸含量;基于主成分分析法对4个不同套袋时间和不套袋的果实进行综合评价,结果显示,7月6日套袋处理果实综合品质最佳,其次为7月26日套袋和6月16日套袋处理。该研究结果为金兰柚套袋时间选择提供了理论依据。In order to explore the optimal bagging time of Jinlan pomelo and provide a theoretical basis for the bagging technology of Jinlan pomelo,Jinlan pomelo was used as material to compare the temperature,humidity and light intensity after bagging and the effects on the internal and external quality of Jinlan pomelo fruit.The results showd that the temperature and humidity increased,the light intensity decreased after bagging.Compared with no bagging,bagging treatment could improve fruit surface color,increase fruit peel thickness,decrease fruit total sugar content and titratable acid content.Based on principal component analysis(PCA),the comprehensive evaluation of the four bagging times and non-bagging fruits showed that the fruit with the best comprehensive quality was bagged on July 6th,followed by bagging on July 26th and bagging on June 16th.The results of this study provide a theoretical basis for bagging time selection of Jinlan pomelo.
