| Abstract: | Based on the discussion on concepts of frost injury, frost, freeze injury and cold injury, and the key factors of low temperature and its duration which take a direct effect on the frost injuries, the field experiment were designed. According to the frost injury index made by pre-Soviet Union and our experiment results,the frost injury index of maize and wheat in Ningxia province were determined,which established a foundation for NOAA satellite to monitor frost injuries by remote sensing. At last, the practicable measures for preventing crops from frost injuries were put forward. |
