Other claims from this paper (16)
- Intervention effect Irrigation at the 11-leaf stage (IV) increased the two-year average net photosynthetic rate by 17.0% relative to no irrigation
- Intervention effect Irrigation at the silking stage (IS) increased the two-year average net photosynthetic rate by 27.2% relative to no irrigation
- Association Intercellular CO2 concentration increased as planting density increased
- Association Stomatal conductance, transpiration rate and net photosynthetic rate decreased as planting density increased
- Association Leaf water use efficiency decreased as planting density increased
- Intervention effect High planting density significantly reduced leaf photosynthetic capacity
- Intervention effect Irrigation treatments significantly increased leaf relative water content
- Intervention effect High planting density significantly decreased relative water content during the silking and filling stages
- Intervention effect Irrigation at the 11-leaf stage (IV) significantly increased photosynthetic capacity
- Intervention effect Irrigation at both stages (IVS) significantly increased photosynthetic capacity after irrigation at the 11-leaf stage
- Intervention effect Irrigation at the 11-leaf stage (IV) decreased leaf water use efficiency
- Intervention effect Irrigation at the silking stage (IS) significantly increased photosynthetic capacity over two years
- Intervention effect Irrigation at both stages (IVS) significantly increased photosynthetic capacity after silking-stage irrigation over two years
- Intervention effect The highest grain yield was obtained with IVS at medium density, not significantly different from IS
- Intervention effect The IVS treatment used two times more water than the IS treatment
- Recommendation Medium planting density combined with silking-stage supplementary irrigation is a suitable water-saving planting model
