枸杞果实、叶片、枝条中铜含量与土壤背景值相关性研究

Correlation of Background Values of Copper Content among Wolfberry Fruits,Leaves and Branches

对枸杞果实、叶片、枝条中铜含量与土壤有效铜、全量铜的调查分析结果表明:枸杞果实铜素含量与土壤有效铜、全量铜含量呈现正相关;枸杞枝条铜素含量与土壤有效铜含量呈极弱的负相关,与土壤全量铜含量呈极弱的正相关;枸杞叶铜素含量与土壤0~80 cm有效铜含量呈极弱的正相关,与土壤全量铜含量呈极弱的负相关。

Through the investigation and analysis of copper content in wolfberry fruits,leaves and branches and available copper and total copper in soil,it was found that the copper content in wolfberry fruits was positively correlated with available copper and total copper content in soil;while the copper content in wolfberry branches was negatively correlated(very weak)with available copper content in soil,and positively correlated(very weak)with total copper content in soil.The copper content in wolfberry leaves was positively correlated(very weak)with available copper content in soil and negatively correlated(very weak)with total copper content in soil.
