【摘要】 探讨了我国主要产茶区 13个茶园不同叶龄茶叶锰含量的分布规律 ,土壤 0 .0 2mol/LCaCl2 提取的活性锰与土壤 pH的关系及茶叶锰含量与土壤 pH、土壤活性锰的关系。结果表明 :不同叶龄茶叶锰含量的分布规律为老叶 >成叶 >嫩叶 ;茶叶锰含量和土壤活性锰与土壤pH均呈显著负相关关系 ;茶叶锰含量与土壤活性锰呈显著正相关关系 ,茶园土壤 0 .0 2mol/LCaCl2 提取的活性锰可作为茶叶吸收利用的有效态锰更多还原

【Abstract】 Distribution of manganese content in tea leaves, relationships between Mn content in tea leaves/active Mn in soil extracted by 0.02mol/L CaCl 2 and soil pH and between Mn content of tea leaves and active Mn in soil extracted by 0.02mol/L CaCl 2 for thirteen tea gardens from East China were discussed in the paper. The results showed that: the law of distribution of Mn in tea leaves was old leaf>mature leaf>young leaf; both Mn in the tea leaves and active Mn in soils extracted with 0.02mol/L CaCl 2 were nagtively correlated with soil pH, and furthermore Mn in tea leaves was positively correlated with active Mn in soil; the uptake of Mn by tea leaves was best predicated linely by the amounts of 0.02mol/L CaCl 2 extractable Mn in soils, consequently, 0.02 mol/L CaCl 2 extractable Mn of soils could be regarded as the "tea leaf available Mn".更多还原
