摘　　要：目的探究紫娟在井冈山引种及井冈红茶在井冈山的适制性。方法参照《国家茶树品种区域实验实施细则》《品种区域试验茶树栽培管理和鉴定》,采用国家标准方法研究紫娟引种井冈山后的栽培特性、产量、品质等。结果紫娟引种井冈山后,采摘期较福鼎大白茶晚10 d以上,移栽成活率为91.67%;紫娟生长势显著优于福鼎大白茶,株高为74.33 cm、树幅为81.66 cm;2020年采摘鲜叶微波制样后测定茶多酚含量为36.29%、花青素含量2.34%、水浸出物含量46.52%均显著高于福鼎大白茶;紫娟鲜叶制成红茶后,茶多酚含量29.15%、花青素含量1.92%、茶黄素含量0.46%,这3项指标均显著优于福鼎大白茶,经感官审评,紫娟制作的红茶得分高于对照样品,滋味、香气、叶底均高于福鼎大白茶。结论紫娟适宜在井冈山及周边红茶、特色茶生产基地推广种植。Objective To explore the introduction of Zijuan in Jinggangshan and the suitability of Jinggang black tea in Jinggangshan. Methods According to The implementation rules of national tea variety regional test and The cultivation management and identification of tea variety regional test, the cultivation characteristics, yield and quality of C.sinensis var.assamica(Masters) Kitamura cv. Zijuan(Zijuan) introduced into Jinggangshan city were studied by using China standards. Results The picking period of Zijuan was more than 10 days later than C.sinensis var. Fudingdabaicha after planted in Jinggangshan, and the transplant survival rate was higher at 91.67%. The growth trend of Zijuan was significantly better than Fudingdabaicha, with a high plant height of 74.33 cm and a tree length of 81.6.6 cm. The content of tea polyphenols was measured to be 36.29%, antholic content was 2.34%, and the content of leachate was 46.52%, all significantly higher than Fudingdabaicha after picking fresh leaf microwave samples in 2020. Tea polyphenol content of 29.15%, antholic content of 1.92%, tea flavonin content of 0.46%, these 3 indicators were significantly better than Fudingdabaicha after produced black tea. It had higher score than the control yield, taste, aroma, leaf bottom. Conclusion Zijuan is suitable for planting in Jinggangshan and its surrounding black tea and characteristic tea production bases.
