To study the effects of four trace elements Mn, Fe, Zn and Cu on growth of the 2nd- and the 3rd-years Paeonia lactiflora.
The experiment was designed as randomized blocks. The data of physiological parameters such as fresh weight of root, numbers of bud and root division, length and diameter of the root and the contents of paeoniflorin in root were measured after fertilized with the four trace elements. Also the contents of the four trace elements in soil and roots, stem and leaves of P. lactiflora were detected by atomic absorption spectrometry.
The growth of the P. lactiflora was improved and the content of paeoniflorin was increased by proper level of Mn, Fe, Zn and Cu, but depressed by the higher level. Only Zn can be accumulated in the roots of P. lactiflora.
研究锰、铁、锌、铜四种微量元素对二年生和三年生芍药生长的影响。
试验采用随机区组设计。在施用四种微量元素后，测定根鲜重、芽数、根分枝数、根长和根直径以及根中芍药苷含量等生理参数数据。同时采用原子吸收光谱法检测土壤及芍药根、茎、叶中四种微量元素的含量。
适量的锰、铁、锌、铜可促进芍药生长，提高芍药苷含量，而高浓度则起抑制作用。只有锌能在芍药根中积累。
