摘要
系统分析了近40多年来金衢盆地、湘南及赣南地区柑桔冻害气候特征、越冬期低温变化规律及发展柑桔生产的气候对策。应用谱分析方法,得出极端最低气温主要周期为2—3年,负积温主要周期为9—11年,提出柑桔冻害出现频率以金衢盆地、赣东南地区最大,湘南大部地区、赣南及闽北柑桔冻害频率最小。预测本区柑桔冻害在本世纪末金华地区有中度冻害,吉安、衡阳两地区在2000年前柑桔基本上不会发生冻害。
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.
