茶树是喜湿植物,在水分条件充裕时,新梢生长旺盛、展叶数量多、持嫩性强、内含成分丰富。因此,在我国多数茶区春季雨水充沛、空气相对湿度大,加上其他环境因素协调,茶叶品质优良。而夏、秋季降雨量相对减少,尤其是日照时数长、强度大,故水分蒸发、蒸腾量大,相对缺水,甚至造成干 Tea trees are like wet plants, in the water conditions are abundant, the new shoots strong growth, the number of exhibition leaf, holding strong tendentious, containing rich ingredients. Therefore, most of China’s tea area with plenty of spring rain, air relative humidity, coupled with the coordination of other environmental factors, the quality of tea. However, the rainfall in summer and autumn is relatively reduced, especially when the sunshine hours are long and the intensity is high, so the water evaporates, the transpiration is large, the relative water is short, and even the dry
