前言云南大种是我国建制红茶的优良茶树品种之一,起源于西南原始森林,喜湿喜温,植株高大,叶形较大,叶肉肥厚,产量高,品质好,在同样的栽培技术和管理条件下,产量比当地其它品种均高,加工成红碎茶为出口畅销产品。由于该品种特性优异,从五十年代起,许多产茶省都陆续引种,有些科研单位作了系统的、较细致的调查,对其特征特性以及引种后的变异情况进行了详细的研究。如福建省闽东地区自1952年开始引种,经多年的调查研究,认为云南大叶种在红茶产区中确实是一个高产优质的大叶群体,值得广泛试种与逐步推广,但要选一些土壤气侯较为适宜、南向而避风之山麓,湿度较
Introduction Yunnan Dacai is one of the fine varieties of tea cultivated in China. It originates from the virgin forest in southwestern China, enjoys hi-temperature, high humidity, high leaf shape, hypertrophy of leaf, high yield and good quality. In the same cultivation technology and management Under the conditions, the output is higher than other local varieties, processed into red broken tea for export selling products. Due to its excellent characteristics, many tea-producing provinces have been introduced since the 1950s. Some research institutes have conducted systematic and detailed investigations and conducted a detailed study on their characteristics and variation after introduction. For example, Fujian Province, Fujian Province, the introduction of the region since 1952, after years of investigation, that the Yunnan big leaf species in the black tea production area is indeed a high yield and quality of the big leaf groups, it is worth extensive trial and gradually promote, but to select some Soil climate is more appropriate, south to the foothills of the storm, humidity more
