信阳茶区生态环境分析与评价

AN ANALYSIS OF THE ECOLOGICAL CONDITIONS IN THE XINYANG TEA-PRODUCING AREA

通过对信阳茶区与全国茶区生态环境对比分析,本文认为:（1）温度是影响茶叶质量最关键的因素之一,北亚热带的温度条件是生产优质名茶的最佳条件之一;（2）信阳茶区地处北亚热带,区内水分条件优越,云雾条件良好,是优质茶叶的适生区;（3）信阳茶区的地貌类型以低山丘陵为主,宜茶地面积广阔,耕作强度小,发展茶叶生产的潜力较大;（4）信阳茶区茶树病虫害较少,农药使用量很少。因此,若经营得当,信阳茶区不仅会成为我国优质茶叶的产区,而且信阳茶叶也可在国内外市场上占据一定的优势。

Comparing the ecological conditions of the tea-producing area in Xinyang with that in the other places in China, we have obtained the following conclusions; (1)The temperature is one of the most important factors that affect the tea quality,and the temperature of the Northern Subtropical Zone is one of the best for high quality teas. (2)The Xinyang tea-producing area which is located in the Northern Subtropical Zone has favourable moisture condition and fogs, and is a suitable area for high quality tea production. (3)The landforms in Xinyang tea-producing area are mostly low-mountains and hills;the area of land suitable for growing tea is large and the farming intensity of land is low. Therefore, the Xinyang tea-producing area is a high quality tea-producing area. (4) The Xinyang tea-producing area is rarely affected plant diseases and insect peses,the pesticide is little used. If management and administration are improved, the Xinyang tea-producing area will not only become a high quality tea-producing area in China,but also will have a superior position in the domestic and foreign markets.
