Abstract

Eastern Jilin Province is one of the most frequent areas of rice chilling injury, vulnerability is used to reflect the possibility of hazard bearing body by stress factors Stress loss is the key factor in the formation of disaster risk, disaster risk is connected with the disaster bridge, the paper's natural vulnerability of rice to start the application CERES-Rice model daily by the growth of rice simulation grid, select a typical case of cold damage and the average years of meteorological data as input to the model, excluding the impact of water stress calculation key physiological parameters loss rate of different rice growth stages due to the cold damage caused by the final fitting-based CERES-Rice model different rice growth stages vulnerability curve, booting - heading in rice cold damage the most sensitive, followed by the heading stage - maturity, sensitivity is the weakest of transplanting - booting stage. Fragility curve established to provide early warning of threatened rice chilling injury occurs, estimates varying degrees of cold damage may cause loss of crop production, achieve rice chilling injury risk in real-time warning.
