Other claims from this paper (6)
- Observation Heat episodes were more severe in Central China than in East and Southwest China.
- Method / resource The duration and intensity based HDH index was needed to describe the heat–yield correlation.
- Association Heat episode variability was negatively associated with observed rice grain yield across all subregions.
- Association In East China, rice yield decreased 113.9 kg ha −1 for each 1.0°C·d increase in HDH.
- Association In Central China, rice yield decreased 19.1 kg ha −1 for each 1.0°C·d increase in HDH.
- Association In Southwest China, rice yield decreased 22.2 kg ha −1 for each 1.0°C·d increase in HDH.
