土壤中不同形态铝与贵州红山茶叶片铝含量关系的研究

Study on Relationship between Different Aluminum Forms in Soil and Aluminum in the Leaves of Camellia kweichowensis

[目的]为了研究不同形态铝与贵州红山茶叶片铝含量的关系。[方法]对贵州特有植物贵州红山茶分布地九龙山土样进行测定分析,对该地土壤理化性质和不同铝形态含量以及与贵州红山茶叶片铝含量的相关性进行了研究。[结果]贵州红山茶叶片铝含量与土壤pH呈0.05水平显著负相关,与0.02 mol/L CaCl2可提取铝含量呈0.01水平显著正相关关系,而与其他所测指标相关性不大。[结论]贵州红山茶主要吸收土壤游离态铝离子。

[Objective]The research aimed to study the relationship between different aluminum forms and aluminum in the leaves of C.kweichowensis.[Method]Soil samples was collected from Jiulong mountain,where an endemic plant of Guizhou Camellia kweichowensis was planted.Physicochemical properties of soil,five forms of Al and the correlation were studied.[Result]There were significant negative correlation （P ＜ 0.05） between the content of Al in C.kweichowensis leaves and soil pH.The content of Al in C.kweichowensis leaves and 0.02 mol/L CaCl2 extractable Al had significant correlation （P ＜ 0.01）.But the correlations weren＇ t significant between the content of Al in C.kweichowensis leaves and other indicators in study.[Conclusion]C.kweichowensis.absorbed aluminium ion found free in soil.
