Abstract:
Orange freeze injury climatic features and the law of low temperature change in the overwinter period and climatological contermine to develop orange production in Jinhua-Quxian Basin and both in the southern Part of Hunan and Jiangxi Provinces in recent 40 years are analyzed systematically. Spectrum analysis suggests that there are principal period lengths of 9-10 years of negative accumulated temperature. The frequency and the probability of orange freeze injury occurrence are the biggest in Jinhua-Quxian basin and in the southeast part of Jiangxi Province,and smaller both in southern part of Hunan and Jiangxi provinces and the northern part of Fujian. It is expected that a medium degree of freeze injury of orange to the end of century in Jinhua county will appear,and freeze injury of orange to the end of the century will not appear both in Jianxian and Hengyang county.
