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%。

Abstract:

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 FJAT-0809-GLX 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%.
