目的
2
分析不同产量下天麻根际微生物的多样性,探讨土壤微生物对天麻产量的影响。
方法
2
该试验采用16S DNA和内转录间隔区(ITS)序列高通量测序对天麻根际土壤中高产土样(GC)和低产土样(DC)下的细菌和真菌群落多样性进行分析。

结论
2
在不同产量下,天麻根际土壤中的真菌群落和细菌群落中均存在差异微生物,推测这些微生物与天麻产量高低有关,研究结果可为后续天麻的高产研究提供重要的理论基础。
Objective
2
To analyze the microbial diversity in the rhizosphere soil of
Gastrodia elata
with different yields and explore the influence of soil microorganisms on the yield of
G. elata
.
Method
2
The experiment adopted the 16S DNA and ITS high-throughput sequencing technologies to study the diversity of the bacterial and fungal community in the rhizosphere soil of
G. elata
with high yield (GC) and low yield (DC).
Result
2
Proteobacteria, Firmicutes, and other unidentified Bacteria were dominant in the rhizosphere soil of
G. elata
. The dominant rhizosphere fungi were
A
scomycota, Basidiomycota, and Mortierellomycota. There was no significant difference in microbial community abundance in the high-yield and low-yield rhizosphere soil of
G. elata
, but there was a significant difference in species composition. Thirty-eight microbes such as
Bradyrhizobium
,
Schleiferilactobacillus
, and
Archaeorhizomyces
were gathered in large numbers in the high-yield rhizosphere soil, and thirty microbes such as
Fusarium
,
Coprinellus
, and
Nitrosotalea
were gathered in large numbers in the low-yield rhizosphere soil. At the level of genus and species, there were six different species in the high-yield and low-yield rhizosphere soil of
G. elata
, among which
Russula mariae
,
Archeaeorhizomyces
, and
Ilyonectria
were gathered in the high-yield rhizosphere soil of
G. elata
, while
Nitrosotalea
,
Coprinellus disserminatus
, and
Fusarium
were gathered in the low-yield rhizosphere soil of
G. elata
.
Conclusion
2
There are different microorganisms in the rhizosphere soil of
G. elata
with different yields, and it is speculated that these microorganisms are related to the yields of
G. elata
. The research results are expected to provide a vital theoretical basis for the follow-up study of the high yield of
G. elata
.
