Study on Monitoring and Early Warning Technology of Rice Heat Injury in the Three Gorges Reservoir Area

Heat injury is one of the main meteorological disasters for rice in the Three Gorges Reservoir Area.Based on the physiological studies,meteorological factors(daily maximum temperature(℃),daily mean temperature(℃)and relative humidity) were screened to develop the rice heat injury accumulating damage index.Combined with weather forecast,the index was used to dynamically monitor the rice heat-induced damage and present the early warning for cumulative high Temperature-Induced damage to rice,which was a guide to defend the rice against heat injury to some extent.
