摘　　要：选用湖北省推广面积较大的茶树品种鄂茶10号一芽四五叶为原料,对青砖茶关键工序-渥堆进行三因素(茶坯含水量、渥堆温度和湿度)三水平的正交优化试验。结果表明,茶坯含水量和渥堆湿度对青砖茶品质形成影响较大;最佳渥堆参数如下:茶坯含水量40%,发酵环境湿度70%,发酵环境温度45℃。One bud four five leaves of the tea tree variety E tea No.10 popularized in Hubei Province were selected as the raw materials.An orthogonal optimization experiment was conducted on the key process of Qingzhuan tea,pile-fermentation,with three factors(tea dhool moisture content,temperature,and humidity)at three levels.The results showed that the moisture content of the tea dhool and the humidity of the pile-fermentation had great influence on the quality of Qingzhuan tea;the optimal parameters were as follows:Moisture content of the tea dhool(40%),humidity(70%)in the fermentation environment,and temperature(45 ℃)in the fermentation environment.
