陕南茶树栽培区域生态与地方品种分布

ECOGEOGRAPHICAL AND LOCAL TEA VARIETIES DISTRJBUTION OF TEA PLANTATION IN SHANXI PROVINCE

陕南秦巴山区是亚热带北缘地区。由于生态环境复杂,地区差异性大,茶树栽培与引种受到一定限制。大致以汉江谷地粮作区为界,南部大巴山北麓低山丘陵区为适栽区;北部秦岭南麓低山丘陵区则为次适栽区。地方茶树群体品种有7个,约由28个地方品种组成,呈斑、块状分布。

The Qinling-Daba Mountains of Shanxi is located in the north margin of subtropical zone,where there are complex ecological conditions which,differ greatly with places,and so to somewhat limit the distribution of the cultivated tea plants.Taking the grain-planting area in Hanjang River as a center,to the south, the low mountains and hills zone along the north slope of Daba Mountains is a relative suitable region for tea plantation :and to the north, that along the south slope of Qinling Mountains is a subsuitable region.The local ancient tea populations are divided into seven groups constituted with 28 varieties spotting in the regions.Five of them locate in the north slope of Daba Mountains, while the others locate in the south slope of Qinling Mountains.Due to the differences of ecohabitats,the populations appear in different constitutions and quality characteristics, and consist of masses of good eccgeographical types and individuals,which are the material bases of varietilization of tea production in Shanxi province.
