摘要
对海南各市县30个胡椒园中0～20cm土层的土壤样品进行了测试分析。结果表明,有一半的土壤样品pH≤4.5;13.33%的土壤样品有机质含量偏低;土壤全N、碱解N丰富;23.33%的土壤样品缺少有效P;30.00%的土壤样品缺少有效K;交换性Ca、Mg严重缺乏;有效Fe、Zn、S丰富,有效B严重缺乏,10.00%的土壤样品均缺乏有效Mn、Cu。
Top soil（0-20cm） samples collected from 30 gardens of Black Pepper（Piper nigrum） in Hainan Province were tested. The results showed that the soil pH of 50% soil samples was obviously lower（≤4.5）; that soil organic matter of 13.33% soil samples was in low status; that total N and alkali hydrolysable N were abundant; that 23.33% and 30.00% of soil samples were deficient of available P and K respectively; that the soil samples were heavily deficient of available Ca, Mg and B but rich in available Fe, Zn and S; and that 10.00% of the soil samples were deficient of available Mn and Cu.
