摘　　要：本文以琼中和保亭作为研究区域,采集了槟榔园土壤样品396个,测定并评价了土壤养分。结果表明:两县土壤pH值及养分分布特点相似,均呈现较强的酸性,有机质和碱解氮均处于较适宜水平,磷钾则表现出极度缺乏。建议在槟榔生产中注重保氮、增磷钾,确保槟榔的生育期有充足的养分。396 soil samples collected from Areca catechu L.land in Qiongzhong and Baoting,Hainan Province were determined.The results showed that the soil in Qiongzhong and Baoting had the similar pH and and nutrient distribution characteristics.The soil fron two countries also appeared strong acidity.The organic matter and available nitrogen kept the suitable level and the phosphorus and potassium were short.Based on this,in betelnut production,the nitrogen fertilization should be kept and the phosphorus and potassium fertilization should be increased in Areca catechu L.land in Qiongzhong and Baoting,Hainan Province.
