Other claims from this paper (11)
- Intervention effect N absorption, translocation and fertilizer-N use efficiency were significantly influenced by N application rates.
- Intervention effect Amount of N translocation in the grain-filling period increased significantly with N application rate.
- Intervention effect Agronomic efficiency and partial factor productivity showed an obvious reduction as N application rate increased.
- Intervention effect Manual-transplanted seedlings had more N accumulation after heading than machine-transplanted seedlings.
- Intervention effect Manual-transplanted seedlings had a higher ratio of N accumulation after heading than machine-transplanted seedlings.
- Intervention effect Manual-transplanted seedlings had more N translocation at the grain-filling stage than machine-transplanted seedlings.
- Intervention effect Manual-transplanted seedlings had a higher rate of N translocation at the grain-filling stage than machine-transplanted seedlings.
- Intervention effect Manual-transplanted seedlings had higher NHI, PE and PFP than machine-transplanted seedlings.
- Intervention effect Manual-transplanted seedlings had fewer N accumulations before heading and at maturity than machine-transplanted seedlings.
- Intervention effect Manual-transplanted seedlings had lower contributions to grain-N and lower RE than machine-transplanted seedlings.
- Observation Manual- and machine-transplanted seedlings showed the same trend of N accumulation before heading and at maturity.
