采用化学分析方法对河口县8个香蕉种植区的194个土壤样品的养分指标进行分析，结果表明：71.6%的土样pH值在正常范围内；有机质、水解氮、有效磷、速效钾、交换镁低于临界值20 g/kg、90 g/kg、10 mg/kg、100 g/kg、50 mg/kg的土样分别为23.2%、30.4%、59.3%、75.8%和63.9%；所有土样的有效铁、锌含量均高于临界值；少数样品的交换钙、有效铜、锰含量低于临界值。据此提出河口县香蕉园相应的施肥建议，对指导香蕉的合理施肥具有重要意义。

194 soil samples from banana plantations in Hekou country were analyzed. The results showed that 71.6% of soil samples soil pH was remained within the normal limits. The organic matter content in 23.2%of soil samples were lower than 20 g/kg, available N content in 30.4%of soil samples were lower than 90 g/kg, available P content in 59.3%of soil samples were lower than 10 mg/kg, available K content in 75.8% of soil samples were lower than 100 g/kg, exchangeable Mg content in 69.3% of soil samples were lower than 50 mg/kg. Soil available Fe and available Zn content in all soil samples were higher than the critical value. Soil exchangeable Mg, available Cu, available Mn content in few of samples were lower than the critical value. The study result can improve the effectiveness of soil improvement and soil nutrients management provided scientific basis.
