Other claims from this paper (8)
- Intervention effect Aboveground dry weight at 5, 10 and 20 cm was significantly greater than at 0 cm.
- Intervention effect Root surface area increased significantly with irrigation depth.
- Mechanism The increased root surface area was attributed to greater root length and branching.
- Intervention effect Subsurface irrigation significantly increased root length below 15 cm.
- Intervention effect Subsurface irrigation increased deep-layer root distribution ratios by 1.2 to 5.7 times.
- Intervention effect The surface-layer root distribution ratio decreased.
- Intervention effect Root diameter decreased with the shift toward deeper roots.
- Mechanism The decreased root diameter may relate to more branches and fewer thick nodal roots.
