Other claims from this paper (11)
- Intervention effect Higher fertilizer (N and P) use raised early tiller-stage dry matter accumulation, which then decreased.
- Intervention effect Irrigation mode made no significant difference to early tiller-stage dry matter accumulation.
- Intervention effect Dry matter accumulation increased significantly from later tiller growth to the tasseling stage under the water and fertilizer treatments.
- Intervention effect Continuous submergence dry matter accumulation was 12.1% higher than AWD at fertilizer level F1 at the tasseling stage.
- Intervention effect Continuous submergence dry matter accumulation was 22.1% higher than AWD at fertilizer level F2 at the tasseling stage.
- Intervention effect Continuous submergence dry matter accumulation was 61.9% higher than AWD at fertilizer level F3 at the tasseling stage.
- Intervention effect Under AWD, net dry matter accumulation and community growth rate peaked and increased significantly from tasseling-milk stage at F1 to later tillering-heading stage at F2 and F3.
- Observation Dry matter was distributed among organs in the order grain, stem, leaf, root at the yellow maturing stage.
- Intervention effect Continuous submergence harvest index decreased by 12.4% at F2 compared with F1.
- Intervention effect Continuous submergence harvest index decreased by 17.9% at F3 compared with F1.
- Method / resource A cubic equation fit rice dry matter accumulation better than a Logistic equation.
