本文主要根据2014年获得第三届“国饮杯”评比红茶类特等奖第一名的生产实践,针对以凌云白毫茶品种为原料研制的“缘韵”红茶加工工艺,包括鲜叶采摘、晾青、摇青、萎凋、揉捻、发酵、理条、干燥等加工工序的关键技术进行总结,研究了“缘韵”红茶产品不同工艺对其品质的影响.

2016年和2008年,八桂凌云茶业有限公司雾中园茶园遭遇了50年一遇的低温冰冻天气,气温降至-5～0℃,喜温喜润的茶树在气温骤降的情况下,会出现不同程度的冻害.论述了冻害发生的机理,阐述了茶树受冻害的症状,提出了防治措施,并总结了茶园冻害后采取补救措施的效果,以供参考.

为探讨利用红茶原料加工黑茶的工艺,选用凌云白毫荼品种鲜叶加工的红茶、绿茶为原料(绿茶1号、绿茶2号、红茶1号、红茶2号),在控温控湿条件下,不同的“渥堆”时间、温度、湿度条件下进行黑茶加工工艺试验,通过对试验样品进行感官审评及生化成分分析,研究“渥堆”过程的“渥堆”叶含水量、水浸出物、茶多酚、氨基酸、茶黄素、茶红素、茶褐素含量变化情况及对六堡茶品质影响.结果表明,利用红茶为原料加工黑茶,品质达到或超过传统黑茶品质要求,且减少了杀青工序、缩短了黑茶加工的渥堆时间及加工周期,降低了生产成本,可提高黑茶产业整体效益.

The invention relates to the new technical field of production for a new kind of tea, and particularly relates to a production method for purple tea. The whole process specifically comprises a selective breeding method for kinds and raw materials, and a production method for finished tea leaves, wherein the selective breeding method for raw materials is divided into single-plant selective breeding and group selective breeding, which comprises the following steps that: first, through single-plant selective breeding, different kinds of purple strains, purple-red strains and red strains are obtained, and performing trial production, and then selecting high-quality strains, and performing the group selective breeding on the raw materials of the strains, wherein the pink-purple finished tea is finally produced via the tea-producing processes of six kinds of tea. Via the implementation of the production method disclosed by the invention, the seventh tea, i.e., purple tea, is produced, and a wonderful product is added in the tea leaf family in China.
