Other claims from this paper (7)
- Intervention effect Intercropping increased C. pilosula root yield by 3.2%-18.7% relative to monoculture.
- Intervention effect Intercropping increased active ingredient concentrations by 5.5%-56.9% relative to monoculture.
- Intervention effect Intercropping increased active ingredients yield by 29.7%-47.1% relative to monoculture.
- Mechanism Enhanced photosynthetic capacity, with larger leaves and higher photosynthetic rate, increased total carbon assimilation in C. pilosula.
- Mechanism Upregulated C/N metabolism strengthened utilization and storage capacity of photosynthetic assimilates in roots.
- Intervention effect The intercropping advantage for C. pilosula was maximized at 60 kg N ha−1.
- Intervention effect Excessive nitrogen at 120 kg N ha−1 diminished intercropping benefits and reduced active ingredient concentrations.
