Other claims from this paper (10)
- Intervention effect Faba bean/maize intercropping with maize residue return increased faba bean yield by 26% compared with monocropping.
- Intervention effect Faba bean/maize intercropping with maize residue return increased maize yield by 27% compared with monocropping.
- Intervention effect Faba bean/maize intercropping with maize residue return increased broccoli yield by 9.1% compared with monocropping.
- Intervention effect Nodulation-related gene expression in faba bean roots intercropped with maize increased 1.5–2.3-fold compared with monoculture.
- Mechanism More than half of the N2 fixation increase of faba bean under intercropping was due to interactions with micro-organisms.
- Observation Nine key bacterial genera were identified in the faba bean rhizosphere by 13C-DNA stable isotope probing.
- Mechanism Agromyces, Arthrobacter and Bacillus directly fix N2.
- Mechanism Lysobacter and Paenibacillus directly fix N2.
- Mechanism Gemmatimonas, Heliobacillus and Natronocella increase N2 fixation capacity of Azotobacter by providing additional carbon sources.
- Recommendation The authors recommend adopting and optimizing faba bean/maize intercropping with residue return.
