- Intervention effect Optimal fertilization under controlled irrigation increased rice yield by 8.5%~9.8% compared with farmers practice under regular irrigation.
- Intervention effect Optimal fertilization under controlled irrigation increased stem diameter by 9.4%~17.5% at 40 days after heading compared with FFP.
- Intervention effect Optimal fertilization under controlled irrigation increased stem wall thickness by 12.7%~21.2% at 40 days after heading compared with FFP.
- Observation The index of lodging resistance of rice was reduced by 15.4%~21.1% under the optimized treatment.
- Intervention effect OPT-30 increased rice yield by 15.5% compared with FFP-25.
- Intervention effect OPT-30 reduced the index of lodging resistance by 16.8% compared with FFP-25.
- Association With increasing plant density under the same fertilizer and water management, rice yield and the index of lodging resistance showed no significant differences.
- Observation The number and area of great and small vascular bundles and the thickness of mechanical tissue increased in the optimized treatments.
- Observation The great and small vascular bundles of the optimized treatments appeared as approximate circles.
- Observation The weight per 10 cm internode and the sugar to N ratio were enhanced in the OPT-25 and OPT-30 treatments.
- Mechanism Water and fertilizer optimization improves the microstructure of the second basal internodes, facilitates internode filling and gives high lodging resistance in rice.
