【Abstract】 The late spring coldness is the main meteorological disaster in tea production, which seriously affects the production of famous tea. It can be divided into chilling injury and frost disaster. Because the temperature indicators of chilling injury and frost disaster are close, it is easy to mistake the chilling injury as frost disaster. Based on comparing the differences in symptoms and mechanism of chilling injury and frost disaster, this paper proposed their discriminant indicators, which provided a basis for further prevention of frost disaster.更多还原
