海口市美兰区土壤养分状况研究

在海口市美兰区5个乡镇场共采集有效土壤样品2414份,测定了pH值、有机质、碱解氮、有效磷及速效钾含量,按照全国第二次土壤普查养分分级标准和养分丰缺指标划分方案,系统评价了土壤养分状况,结果表明：海口市美兰区土壤酸性较强,pH为5.21,土壤有机质和碱解氮含量处于中等偏上的水平;有效磷含量丰富,速效钾含量缺乏;各养分含量空间分布不均匀。总体来看海口市美兰区土壤养分含量处于中等水平,土壤酸化和养分含量不均衡主要与环境气候、成土母质和人为施肥不平衡关系密切。因此,今后在农业生产中应采取平衡施肥,切记要稳氮、补钾和减磷,提高耕地地力水平,实现农业可持续健康发展。...

A study on soil nutrient status at Meilan district of Haikou city was conducted and 2414 soil samples were collected to determine pH,organic matter,available nitrogen,available phosphorus and available potassium,soil nutrient status was evaluated according to the second national soil survey of nutrient grading standards and nutrient abundance index partitioning scheme,systematically. The results showed that the study area soil was acidity,pH was 5. 21,the content of soil or
