Other claims from this paper (11)
- Observation The root rot disease index of American ginseng increased 4.7 times at another sampling site over 4 years.
- Observation Bacterial diversity in the ginseng rhizosphere increased with the seasons in the first, third and fourth years.
- Observation Bacterial diversity in the ginseng rhizosphere remained steady in the second year.
- Observation The seasonal change of relative abundances of bacteria and fungi showed the same trend in the first, third and fourth years but not in the second year.
- Association Relative abundances of nine microbial genera were negatively correlated with the root rot disease index.
- Association Relative abundances of fourteen microbial genera were positively correlated with the root rot disease index.
- Association Soil chemical properties were significantly correlated with the rhizosphere microbial composition in the Mantel test.
- Association Contents of available potassium and nitrogen were positively correlated with the root rot disease index.
- Association Soil pH and organic matter were negatively correlated with the root rot disease index.
- Observation The second year is the key period for the shift of the American ginseng rhizosphere microbial community.
- Mechanism Disease aggravation after the third year is related to deterioration of the rhizosphere microecosystem.
