摘　　要：从施用浓度、贮藏方式和施用方法进行保鲜功能微生物短短芽孢杆菌FJAT-0809-GLX对龙眼果实保鲜方法的优化,找到一种合理有效而又低成本的方法对龙眼进行保鲜。结果表明,随着稀释浓度的升高,龙眼果实保鲜率逐渐下降,脱粒率逐渐升高,稀释10倍施用时,保鲜率最高,为75%。保鲜功能微生物喷施龙眼后,采用纸包裹龙眼进行贮藏,其保鲜率明显高于用树叶直接贮藏的效果,为53.28%。从喷施方法来看,保鲜功能微生物采前处理龙眼果实,其脱粒率为24.42%,明显高于采后处理的12.96%,保鲜功能微生物FJAT-0809-GLX采后处理的保鲜率最高,保鲜率为83.33%。In order to find reasonable and cheap keeping-fresh method for longan （Dimocarpus longan）,the optimization of application method using the function bacteria strain Brevibacillus brevis to keep the longan fruit （Dimocarpus longan） fresh were compared in this paper.The results showed that the preservation rate was decreased as the concentration dilutions of the fresh-keeping function bacteria strain FJAT-0809-GLX increased,and threshing rate was increased.The highest preservation rate was 75% as the dilution was ten times.The preservation rate of longan fruits with the paper wrapped was higher than that with leaves wrapped,which was 53.28%.The application methods showed that the threshing rate of the fruit for the bacterium spraying before harvest was 24.42%,lower than that spraying after harvest which was 83.33%.
