Research on classification criteria of Chinese olive freezing injury level based on orchard meteorological station data
摘要
Abstract
[Objective]To mitigate the risk of freezing injury to Chinese olive in Fuzhou,classification criteria of Chinese olive freezing injury level is established in this study.[Method]Through field investigation of historical Chinese olive freezing injury events,literature review and orchard observation,60 samples of Chinese olive freezing injury in Fuzhou from 1991 to 2024 were collected.According to morphological characteristics of Chinese olive freezing injury symptoms,Chinese olive freezing injury was classified into five levels:none,light,moderate,severe,and extreme.A fitting equation between Chinese olive freezing injury level and daily minimum temperature of orchards is developed.And through classification analysis method,meteorological classification criteria of Fuzhou Chinese olive freezing injury level is established.[Result]Freezing injury to Chinese olive is classified into five levels,with corresponding threshold values of daily minimum temperature(Tmin)of orchards as follows:none freezing injury(Level 0):Tmin>-1.5℃;light freezing injury(Level 1):-2.5℃<Tmin≤-1.5℃;moderate freezing injury(Level 2):-3.0℃<Tmin≤-2.5℃;severe freezing injury(Level 3):-3.5℃<Tmin≤-3.0℃;extreme freezing injury(Level 4):Tmin≤-3.5℃.Through geographical transplantation tests and comparative validation of Chinese olive freezing injury events in typical years,the established classification criteria of Chinese olive freezing injury level showed a high consistency with actual conditions of Chinese olive in Fuzhou.The matching rate reached 80%or above.[Conclusion]The results indicated that the classification criteria of Fuzhou Chinese olive freezing injury level can provide references for the monitoring and early warning of Chinese olive freeze damage.关键词
