摘　　要：2013年在江西南丰和浙江衢州分别选择75个和41个柑桔园采集土壤和叶片样品,对铜和锰含量进行分析。结果表明,南丰和衢州柑桔园土壤有效铜无一极缺、缺乏或适量,普遍过量,过量果园所占比例分别为85.3%和95.1%;南丰和衢州柑桔叶片铜含量无一缺乏,极少数适量,普遍过量,过量果园所占比例分别为98.7%和95.1%。南丰和衢州柑桔园土壤有效锰无一高量和过量,适量者多,少部分表现为缺乏,南丰缺乏和适量果园所占比例分别为22.7%和77.3%,衢州缺乏和适量果园所占比例分别为26.8%和73.2%;两地叶片锰含量表现差异较大,南丰叶片锰过量果园比例为78.7%,而衢州适量果园所占比例高达97.6%。两地应注意控制铜肥及含铜农药的施用,而南丰柑桔产区还应控制含锰农药的施用。Available copper（Cu）and manganese（Mn）contents in 75 samples of soil and leaves from citrus orchards in Nanfeng of Jiangxi province and 41 samples from Quzhou county of Zhejiang province were analyzed.Results showed that the available Cu in most of soil samples were excessive.The 85.3% and 95.1% of soil samples from Nanfeng and Quzhou were excessive on available Cu,respectively.Cu contents in leaves from Nanfeng and Quzhou were mostly excessive,of98.7% and 95.1% orchards with Cu excessiveness,respectively.Mn contents in the soils from Nanfeng and Quzhou were mostly optimum,only a few samples were deficient.Proportions of orchards with deficient and optimum Mn in Nanfeng were 22.7%,77.3%,respectively,while those of in Quzhou were 26.8% and 73.2%,respectively.Proportion of orchards with excessive Mn contents in leaf from Nanfeng was 78.7%.Proportion of orchards with optimum Mn contents in leaf from Quzhou was 97.6%.Cu containing fertilizers and pesticides should not be used in Nanfeng and Quzhou.Mn containing pesticides of should also not be used in Nanfeng citrus orchards.
