Optimizing the rhizosphere to enhance photosynthesis and functional traits of Cyperus esculentus in saline-alkali soils: A comparison between biochemical amendments and salt-tolerant plant intercropping

Key Points

• Enhancements in photosynthesis and functional traits during intercropping indicate positive responses to biochemicals.
• Photosynthesis increased by 30% with biochemical amendments in saline-alkali soils, highlighting effective interventions.
• This observational analysis compares the effects of biochemical amendments and intercropping using salt-tolerant plants.
• These findings suggest that optimizing the rhizosphere with specific amendments may improve crop resilience in saline environments.
