摘要:

本研究以浙江省台州市黄岩区不同树种套种菜头肾(Strobilanthes sarcorrhiza)的土壤为研究对象,分析了不同套种组合下土壤中有效态微量元素的差异,采用高通量测序技术探讨了不同套种组合对微生物群落结构的影响。结果表明:枇杷林地套种菜头肾后,随着种植年限的增加,土壤有效铁含量从79.83 mg·kg-1显著(p<0.05)上升至155.33 mg·kg-1,而有效锌含量从5.57 mg·kg-1显著下降至3.90 mg·kg-1。主坐标分析(PCoA)与非度量多维尺度(NMDS)的结果表明,不同套种组合的土壤微生物结构存在差异,说明不同的套种方式能够改变土壤微生物的组成。相关分析的结果表明,土壤特定微生物的相对丰度与土壤有效态微量元素含量之间存在显著相关性。

Abstract:

This study investigated the soil of Strobilanthes sarcorrhiza interplanted with different tree species in Huangyan District, Taizhou City, Zhejiang Province. The differences in available trace elements under various interplanting patterns were analyzed, and high-throughput sequencing was employed to examine the effects of different interplanting combinations on the soil microbial community structure. The results showed that in the loquat forest, interplanting with S. sarcorrhiza led to a significant increase (p<0.05) in soil available iron content from 79.83 mg·kg-1 to 155.33 mg·kg-1 with increasing planting years, while the available zinc content significantly decreased from 5.57 mg·kg-1 to 3.90 mg·kg-1. Principal coordinate analysis (PCoA) and non-metric multidimensional scaling (NMDS) indicated structural differences in the soil microbial communities among different interplanting combinations, demonstrating that interplanting patterns can alter microbial composition. Correlation analysis further revealed significant relationships between the relative abundance of specific soil microorganisms and the content of available trace elements.
