一个多世纪以来,依据于野生大茶树的分布、栽茶饮茶的历史、史料的考证和地质变迁等,国内外学者对茶树原产地问题提出了多种论点。但由于对事物认识的局限性,再加各人研究的侧重面不一,故迄今未有定论。笔者曾在《茶叶科学》(1986年第1期)著文指出,我国云南为茶树原产地,滇东南是茶的起源中心。本文进一步就茶树如何从起源中心向外扩散以及茶种之间的变迁问题作一讨论。 For more than a century, domestic and foreign scholars have put forward many arguments on the origin of tea tree, based on the distribution of wild large tea tree, the history of planting tea and tea, textual research and geological changes. However, due to the limitations of understanding of things, together with different emphasis on different aspects of research, it has so far not been conclusive. The author once said in the article “Tea Science” (No.186, 1986) that Yunnan is the origin of tea tree and the southeast of Yunnan is the origin of tea. This article further discusses how the tea tree can spread out of the center of origin and the transition between tea varieties.
