研究了3个无性系茶树品种的成熟叶片、嫩梢(正常芽和对夹叶)及不同器官(嫩梗、嫩叶)内6种元素(钙、镁、铁、锰、锌、铜)的含量及年周期的变化。结果表明,成熟叶片含钙量变化趋势是,3个品种的春叶及东湖早的夏叶均与叶龄呈负相关。政和大白茶、毛蟹的夏叶和3个品种的秋叶含量则与叶龄呈正相关。各品种叶片含镁量与叶龄呈2次曲线相关,而铁、锰、锌、铜元素的含量均与叶龄呈正相关。正常芽叶钙.镁.铁、锌,铜含量高于对夹叶,而含锰量则相反,对夹叶高于正常芽叶。嫩梗钙、镁含量高于嫩叶,而铁、锰、锌、铜的含量则有随季节不同交替变化的趋势。
The effects of six elements (calcium, magnesium, iron, manganese, zinc and copper) in mature leaves, young shoots (normal shoots and opposite leaves) and in different organs (tender stems and young leaves) of three clonal tea cultivars Content and annual cycle changes. The results showed that the change trend of calcium content in mature leaves was negative correlation between leaf age and spring leaf of three cultivars and early summer leaf of Donghu Lake. Zheng and Dabaicha, hairy crabs and three varieties of autumn leaves content was positively correlated with leaf age. Leaf magnesium content of each variety was correlated with the leaf curve quadratic curve, while the contents of iron, manganese, zinc and copper were positively correlated with leaf age. Normal shoots of calcium and magnesium. Iron, zinc, copper content higher than the folder leaves, while manganese content is the opposite, the folder leaves higher than the normal shoots. The tender stems calcium, magnesium content is higher than the young leaves, while the iron, manganese, zinc, copper content with different seasons alternately change trend.
