| 摘 要： | 目的:对三峡库区不同产地重楼属药用植物种植基地的根际土壤及药材中矿质营养元素K,Ca,Mg,Na,Mn,Zn,Cu,Ni的含量及其相关性进行分析评价,为重楼矿质营养元素诊断和指导合理施肥提供参考。方法:采用湿法消解处理重楼根茎及根际土壤,通过原子吸收分光光度法测定,所得数据用SPSS 18.0软件进行分析。结果:重楼根茎中营养元素与根际土壤中营养元素呈现一定的相关性。不同产地重楼根茎及其根际土壤中8种营养元素含量存在显著差异,重楼根茎中各营养元素平均含量排序为KCaNaMgCuMnNiZn,根际土壤则为MgNaCaKMnZnNiCu。重楼对Na,Cu,Ca具有一定的富集能力,重楼根茎及根际土壤中8种营养元素有多重相关性。结论:重楼药材主要通过选择性吸收调控其矿质营养元素的含量;重楼对营养元素的吸收积累具有一定的协同吸收作用。

| Abstract: | Objective: To conduct correlation analysis of mineral nutrient elements in soil and herbs of Paridis Rhizoma growing in different places around three gorges reservoir. Method: Rhizome and rhizosphere soil of Paridis Rhizoma were disposed with the wet digestion method, and then determined by atomic absorption spectrophotometry.Data were analyzed and compared with SPSS 18.0. Result: Nutrient elements in Paridis Rhizoma and rhizosphere soil showed some correlation.There were significant differences existing in concentrations of eight kinds of nutrient elements in rhizome and rhizosphere soil of Paridis Rhizoma from different places.Contents of each nutrient elements in ranking of rhizome was K> Ca> Na> Mg> Cu> Mn> Ni> Zn,and that in rhizosphere soil was Mg >Na >Ca >K >Mn> Zn >Ni> Cu.Paridis Rhizoma had a certain capability of enriching Na,Cu and Ca.Eight kinds of nutrient elements in rhizome and rhizosphere soil had multiple correlation. Conclusion: Main regulation pathway of mineral nutrient elements in Paridis Rhizoma is selective absorption.Coordination among nutrient elements is in favor of accumulation of nutrient elements in Paridis Rhizoma. |
