Abstract: In order to establish a perfect research system of mint tea, high quality fresh stems were used as materials to test production capability under different conditions. Drying temperature at 40 ℃ and consuming time in 40 h could get the best quality of mint tea. Also, it could save time and cost. With the increase of temperature, the change of the quality was a parabola trend. The annual yield and dry weight of fresh stems were 76664.7 kg/hm2, 13117.8 kg/hm2. The general fresh production and dry matter rate of each harvest were 6000.0-6750.0 kg/hm2, 18.0 %-21.0 %. The fresh production increased to 15000.0 kg/hm2 while the dry matter rate decreased significantly to 15.0 %-17.0 % between June and July. The end product could be kept for more than 9 months in close and dark condition.
