摘要
福建烟区土壤中量和微量元素的平均含量交换性钙为519.33mg/kg,交换性镁为34.49mg/kg,有效硫为27.91mg/kg,有效铁为61.07mg/kg,有效锰为13.99mg/kg,有效铜为3.09mg/kg,有效锌为3.32mg/kg,有效硼为0.17mg/kg,水溶性氯为26.30mg/kg。福建烟区土壤交换性镁、有效硼含量不足,有效铁、锰含量丰富,有效铜、锌含量较适宜。
Calculated arithmetic means of medium-element and micro-element contents of tobacco-growing soils in Fujian are as follows： exchangeable Ca 519.33mg/kg, exchangeable Mg 34.49mg/kg, available S 27.91mg/kg, available Fe 61.07mg/kg, available Mn 13.99mg/kg,available Cu 3.09mg/kg, available Zn 3.32mg/kg,available B 0.17mg/kg and water soluble Cl 26.30mg/kg. Exchangeable Mg and available B contents of the soil are evidently deficient while available Fe and Mn are abundant, yet available Cu and Zn are just in the right amounts.
