摘要:

为探究接种不同根际促生菌(PGPR)对白花前胡品质及根际土壤氮、磷、钾含量的影响,并为微生物菌肥的开发与白花前胡大田栽培提供参考,本研究设置9个接种不同PGPR菌株的处理,以接种无菌生理盐水作为对照(CK)。结果表明,各PGPR处理均能显著(p<0.05)提高白花前胡根部白花前胡甲素与白花前胡乙素的含量。除个别处理外,多数处理的白花前胡根部及根际土壤中氮、磷、钾含量均有不同程度提升;白花前胡根部对氮磷钾元素的吸收能力依次为磷>氮>钾。相关分析显示,白花前胡甲素含量与根部氮含量呈显著正相关,白花前胡乙素含量与根部氮含量呈显著负相关,而与土壤磷含量呈显著正相关。综上,接种PGPR可有效提高白花前胡根际土壤氮磷钾含量及其药用成分积累,从而改善药材品质。

Abstract:

To investigate the effects of different plant growth-promoting rhizobacteria (PGPR) on the quality of Peucedanum praeruptorum and the nitrogen (N), phosphorus (P), and potassium (K) content in the rhizosphere soil, and to provide a reference for the development of microbial fertilizers and field cultivation of P. praeruptorum, this study established nine treatments inoculated with different PGPR strains, using sterile saline inoculation as the control (CK). The results showed that all PGPR treatments significantly (p<0.05) increased the content of praeruptorin A and praeruptorin B in the roots of P. praeruptorum. Except for a few treatments, most treatments increased the N, P, and K content in the roots and rhizosphere soil to varying degrees. The absorption capacity of the roots for the N,P,and K elements followed the order: P>N>K. Correlation analysis revealed that the content of praeruptorin A was significantly positively correlated with root nitrogen content, while the content of praeruptorin B was significantly negatively correlated with root nitrogen content and significantly positively correlated with soil phosphorus content. In conclusion, PGPR inoculation can effectively enhance the N, P, and K content in the rhizosphere soil and promote the accumulation of medicinal components, thereby improving the quality of P. praeruptorum.
