摘要
分析了气候因子与我国茶树栽培界限的关系,发现冬季低温条件是茶树栽培北界和垂直高度界限的决定因子。将年极端最低气温≤-15℃≤-5℃低温出现频率10％分别作为划分灌木中小叶型茶树和乔木大叶型茶树栽培北界的气候指标,划分出茶树的栽培北界。灌木中小叶型茶树栽培北界位于朝阳、蚌埠、信阳、商县、武都、泸定、德钦、林芝到错那一线;乔木大叶型茶树栽培北界位于温州、龙岩、韶关、榕江、广南、昆明到六库一线。用年极端最低气温多年平均值-10℃和-3℃作为2种生态类型茶树栽培垂直高度界限指标,推算出茶树栽培垂直高度界限在440～2130m之间。
The relationship between climatic factors and the tea tree cultivated limits is studied. The results show that the temperature condition in winter is the key factor of determining the tea tree cultivated limit in China. We take annual extreme minimum temperature ≤-15℃ and ≤-5℃ (frequency being 10%) as the north cultivated limit of the bush-mid or small leaf type tea tree and the tall tree-big leaf type tea tree,respectively.Therefore,the north limit for the bush-mid or small leaf type tea tree is along Sheyang,Bengbu ,Xinyang,Shangxian,Wudu,Luding,Deqin,Linzhi and Cuona. The north limit for the tall tree-big leaf type tea tree is along Wengzhou,Longyan,Shaoguan,Rongjiang,Guangnan,Kunming and Liuku.The vertical lowest temperature limit of two kinds of tea tree is -10℃ and -3℃ respectively. Then, the vertical limit height of two kinds of tea tree cultivation is between 440 and 2130 meters above sea level.
