不同茶树品种雁荡毛峰茶适制性研究

Study on Productive Character for Yandang Maofeng Tea of Main Cultivated Tea in Yandang

文章以雁荡茶区乌牛早、浙农139、迎霜、中茶108、龙井43、智仁早、本地群体种7个主栽茶树品种为原料,分析其制成的雁荡毛峰茶主要理化成分和感官品质,旨在探明这些品种雁荡毛峰茶的适制性,以筛选出适宜在雁荡茶区推广种植的茶树品种。结果表明,这7个品种内含物丰富,水浸出物含量高于46%,最高的智仁早含量达49.64%,咖啡因含量低于4.5%,但酚氨比相差较大,最低的龙井43酚氨比为3.76,最高中茶108达6.24。龙井43、乌牛早、浙农139、迎霜和群体种都有适制雁荡毛峰茶的潜质。结合感官评审结果及各品种的萌发期,适宜在雁荡地区种植并加工成雁荡毛峰茶的品种为群体种、迎霜、龙井43和乌牛早,也可适当考虑浙农139。

In order to screen out the tea varieties suitable for promotion and planting in Yandang tea area,the main biochemical components and sensory quality of the Yandang Maofeng made from 7 main varieties,including Wuniuzao,Zhenong 139,Yingshuang,Zhongcha 108,Longjing 43,local group species in the Yandang tea area,were studied to determine the suitability of these varieties of Yandang Maofeng.The results showed that the 7 varieties were all rich in content,the water extract content was higher than 46%,the highest one which was Zhirenzao,reaching 49.64%.The caffeine content was all less than 4.5%,but the phenol-ammonia ratio was quite different,the lowest one was Longjing 43,with a ratio of 3.76,and the highest one was Zhongcha 108,with a ratio of 6.24.Longjing 43,Wuniuzao,Zhenong 139,Yingshuang and local group species were all have the potential to be suitable for Yandang Maofeng.Based on the results of sensory evaluation and the germination period of each variety,the suitable varieties for planting and processing into Yandang Maofeng in Yandang area were local group species,Yingshuang,Longjing 43 and Wuniuzao,and Zhenong 139 could also be included to an certain extent.
