Observation The optimum nitrogen application rate was 135 kg ha−1.
Intervention effect At 135 kg ha−1 N, yield promotion over years was more obvious under PFMC than CFC.
Intervention effect At 135 kg ha−1 N, grain N uptake promotion over years was more obvious under PFMC than CFC.
Mechanism Continuous PFMC might accelerate soil organic matter mineralization.
Mechanism Continuous PFMC might increase soil N availability.
Intervention effect Straw incorporation had no obvious effect on yield increment over years versus removal under PFMC.
Intervention effect Straw incorporation had no obvious effect on grain NRE increment over years versus removal under PFMC.
Intervention effect Film mulching with 135 kg ha−1 N improved early growth stage soil thermal condition.
Intervention effect Film mulching with 135 kg ha−1 N enhanced soil N availability.
Intervention effect Film mulching with 135 kg ha−1 N enhanced grain N uptake.
Intervention effect Film mulching with 135 kg ha−1 N enhanced rice yield.
