山茶原产我国长江以南,区内自西至东,各地都发现过野山茶。云南腾冲还保存有山茶半野生林;震撼世界园艺界的24个品种、5个变种的金花茶就是1960年以来在广西及其邻地陆续发现的。而长江以南的丘陵地带遍布重粘性的黄壤和红壤,好多沙砾土、碎石土中的细颗粒也还是粘土,真正的沙质土较少。而长江北岸各省,气候也适宜山茶生长,那里沙质土多,红黄壤很少,但野山荼不在那里落户。与广西、云南接壤的越南北部.也是红黄壤分布区,那里也生长着野山茶。因此,从宏观看来,哪里有粘性的红黄壤,哪里就有野山茶;反之,哪里没有或很少有红黄粘土,哪里就没有野山茶生长。
Camellia native to China’s south of the Yangtze River, the region from west to east, all over the wild tea was found. Yunnan Tengchong also preserved camellia semi-wild forest; shook the world horticultural industry 24 varieties, 5 varieties of Camellia sinensis in 1960 in Guangxi and its neighboring areas have been discovered. The hilly areas to the south of the Yangtze River are all over the heavy-viscosity yellow and red soils. Many of the gravelly soils and gravelly soils are also clays of fine particles, with less real sandy soils. The northern coast of the Yangtze River, climate is also suitable for the growth of Camellia, where sandy soil and more, very few red and yellow soil, but wild mountain tea is not settled there. And northern Guangxi bordering Yunnan, Yunnan is also a distribution area of red and yellow, there is also growing wild Camellia. Therefore, macroscopically, where there are sticky red and yellow soil, there is wild camellia; the other hand, where there is little or no red-yellow clay, where there is no growth of wild camellia.
