| 中文摘要: |
| 采取南丰75个和衢州41个柑橘园土壤及叶片，对样品中铜和锰的含量进行分析。结果表明：南丰和衢州柑橘园土壤有效铜均表现为过量。其中，南丰土壤有效铜平均含量为3.00mg/kg，铜过量比例为85.3%；衢州土壤有效铜含量平均为3.68 mg/kg，铜过量比例为95.1%。南丰柑橘园土壤有效锰含量平均为7.41 mg/kg，缺乏比例为22.7%，适量比例为77.3%；衢州柑橘园土壤锰含量平均为7.21 mg/kg，缺乏比例为26.8%，适量比例为73.2%。南丰和衢州柑橘叶片铜含量均表现为过量。其中，南丰柑橘叶片铜含量平均为54.68mg/kg，过量比例为98.7%；衢州柑橘叶片铜含量平均为51.49mg/kg，过量比例为95.1%。南丰柑橘叶片锰含量平均为117.78 mg/kg，过量比例为78.7%；衢州柑橘叶片锰含量平均为99.79 mg/kg，过量比例仅为2.4%，其余均为适量。 |

| Taking 75 samples of soil and leaf in Nanfeng citrus orchard and 41 samples of soil and leaf in Quzhou citrus orchard, analyzing the available copper (Cu) and manganese (Mn) content of soil and leaf. The results show that: The soil available copper are excessive of Nanfeng and Quzhou citrus orchard. The soil available copper content of Nanfeng citrus orchard is 3.00 mg/kg, the excessive proportions is 85.3%. Meanwhile, the soil average available copper content of Quzhou citrus orchard is 3.68 mg/kg, and the excessive proportions is also very high, even up to 95.1%. The soil available manganese content of Nanfeng citrus orchard is 7.41 mg/kg, its deficiency proportion is 22.7% and optimum proportion is 77.3%; besides, the Quzhou citrus orchard’s soil manganese content is 7.21 mg/kg, its deficiency proportion is 26.8% and optimum proportion is 73.2%. The leaf copper content of Nanfeng citrus orchard is 54.68 mg/kg, its excessive proportion is up to 98.7%; and Quzhou citrus orchard's leaf copper content is 51.49 mg/kg, the excessive proportion is also very high, up to 95.1%.The leaf manganese content of Nanfeng citrus orchard is 117.78 mg/kg, excessive proportion is 78.7%; but the Quzhou’s leaf manganese content is 99.79 mg/kg, the excessive proportion is just only 2.4%, the rest are optimum. |
