- Intervention effect Plastic film mulching increased maize yield by 31.1%–46.4% in 2017.
- Intervention effect Plastic film mulching increased maize yield by 3.6%–34.7% in 2018.
- Intervention effect High planting density significantly increased yield in the dry year 2017.
- Intervention effect High planting density slightly reduced yield in the rainy year 2018.
- Intervention effect Mulching increased photosynthesis and respiration.
- Intervention effect Mulching increased leaf stomatal density and aperture.
- Intervention effect High planting density lowered photosynthetic rate, dark respiration and stomatal conductance.
- Intervention effect High planting density lowered stomatal aperture.
- Association Maize yield correlated positively with photosynthesis, dark respiration and stomatal aperture.
- Intervention effect Mulching increased root activity at maturity.
- Mechanism Changes in root growth and leaf anatomy increased photosynthesis and dark respiration under mulching.
- Mechanism Increased photosynthesis contributed to increased grain yield and biomass under mulching.
