Effects of Exogenous Fusarium oxysporum and Trichoderma viride on Soil Fungal Community of Panax ginseng
on the diversity of soil fungal community and carbon metabolic function of cultivated
Panax ginseng
.
Method
2
Illumina HiSeq 2500 high-throughput sequencing combined with Biolog-ECO was used to analyze the species diversity and functional diversity of soil fungal communities in
P. ginseng
soil under different exogenous treatments.
Result
2
The results of high-throughput sequencing showed that the number and species of microorganisms in the soil were significantly changed after exogenous microorganisms were added. The soil fungi with relative abundance greater than 1% included
Mortierella
sp.,
Fusarium
sp.,
Humicola
sp.,and
Simplicillium
sp.
Mortierella
sp. in each treatment group significantly increased.
Humicola
sp. and
Simplicillium
sp. could be induced to increase by exogenous addition of
F. oxysporum
,while
T.
viride
at a high concentration could significantly inhibit the growth of
F. oxysporum
. As revealed by Biolog and principal component analysis (PCA),the average well color development (AWCD) in the high-dose
T. viride
group (MG) was significantly higher than that in the control group (QS)and the low-dose
F. oxysporum
group(LD). The utilization abilities for amino acids,carboxylic acids,polymers, and amines were enhanced in the MG group,but the microbial metabolic activity was reduced in the high-dose
F. oxysporum
group (LG). There was no significant increase in the utilization of phenolic acids by soil microorganisms in both groups.
Conclusion
2
Exogenous addition of
F. oxysporum
can lead to the growth and reproduction of other pathogenic fungi. Exogenous addition of
T. viride
can enhance the soil fungal community structure and metabolic diversity,inhibit the proliferation of
F. oxysporum
,and improve the soil microbial environment of cultivated
