Hypothesis
How does integrated rice-crayfish farming affect bacterioplankton communities in paddy water?
Conclusion
Integrated rice-crayfish farming significantly alters the composition and stability of bacterioplankton communities in paddy water.
Supporting Evidence
- Integrated rice-crayfish farming did not significantly impact bacterioplankton diversity but altered community composition.
- Chloroflexota was promoted during the tillering stage but reduced during the grain-filling stage.
- Bacillota decreased during the jointing stage while Actinomycetota increased during the flowering stage.
- Environmental factors like TN and phosphate levels were correlated with changes in bacterioplankton communities.
- IRCF improved the robustness and cohesion of bacterioplankton co-occurrence networks.
Takeaway
This study shows that farming rice with crayfish changes the types of bacteria in the water, which can help rice grow better.
Methodology
The study used Illumina high-throughput 16S rRNA gene sequencing to analyze bacterioplankton communities in paddy water during different rice growth stages.
Limitations
The study only covers one year, making it unclear if the effects are long-term.
