海南儋州荔枝园土壤养分现状分析

摘要

对儋州市各乡镇21个荔枝园中0-20cm土层的土壤样品进行了测试分析。结果表明：土壤有机质含量不高,全N和碱解N属于中等偏下水平,而有效P则较丰富,有效K属于中等水平,有23.8%的土壤样品pH≤4.5。调查结果揭示的儋州市荔枝果园土壤养分状况,为今后儋州荔技园土壤养分资源的综合评价和科学施肥提供了基础资料,并提出了儋州荔技园合理施肥及改良利用的建议。%Top soil（0-20cm） samples collected from 21 litchi orchards in Danzhou of Hainan were tested.The results showed that the contents of the soil organic matter were very low,total N and alkali hydrolysable N were lower-middle level,that available P were abund
