摘　　要：试验以秋季英红九号为原料,在发酵湿度分别为90%和95%的情况下,以不同的发酵温度、发酵时间及氧气浓度进行正交发酵试验研究,通过对加工后的茶叶进行评价分析,试验条件下,在90%湿度环境下,氧气浓度是影响茶叶发酵品质最重要的影响因子,较佳的发酵参数为发酵温度34℃、发酵时间5 h、氧气浓度21%。在95%湿度环境下,发酵时间是影响茶叶发酵品质最重要的影响因子,较佳的发酵参数为发酵温度30℃、发酵时间5 h、氧气浓度22%。The orthogonal fermentation experiment was carried out with autumn Yinghong No. 9 as raw material in different temperature, time and oxygen concentration when the fermentation humidity under 90%and 95%. Through the evaluation and analysis of the processed tea, it was concluded under 90% humidity environment, oxygen concentration was the most important factor affecting the tea fermentation quality, and the better fermentation parameters were 34℃ fermentation temperature, 5 h fermentation time and 21% Oxygen concentration;Under 95% humidity environment, fermentation time is the most important factor affecting tea fermentation quality. The best fermentation parameters are fermentation temperature 30 ℃, fermentation time 5 h,22% oxygen concentration.
