| 摘 要： | 第二次土壤普查后首次大规模对海南省文昌市的土壤养分状况进行调查分析,共分析统计了17个乡镇的4127个土样。结果表明:文昌市土壤养分含量总体水平较低,特别是钾素含量严重缺乏;磷素供应能力适中;氮素偏低;从空间分布分析各个地区含量不平衡,相差较大。结果反映了文昌市不同地区养分状况,提出了合理施肥及改良利用的建议,为今后土壤养分资源的综合评价和科学施肥提供了基础支持。 |

| Abstract: | The 4127 soil samples collected from 17 townships in the second national soil survey in Wenchang,Hainan Province were analysed.The results showed that the soil nutrient content in Wenchang was generally low,especially the K content which was heavily deficient.The soil P content was moderate and the soil N content slightly lower in these areas;the soil nutrient content was different in spatial distribution in various townships.The soil nutrient regimes in different townships were presented based on the surve... |
