为了了解乐东县农田土壤养分的现状,为合理施肥提供科学依据,乐东县农技中心结合测土配方施肥项目,全县2008~2009年共采集农化样2 481个,采用测土配方施肥技术规程推荐分析方法,对全部样品测定土壤有机质、pH、速效氮、有效磷、速效钾含量,部分样品抽测土壤有效钙、镁、硫等,共计14 637项次。通过土壤野外调查与室内分析化验汇总,基本摸清了乐东县目前农田土壤养分含量和分布规律,为农民科学种田提供了科学依据。
In order to understand the status quo of farmland soil nutrients in Ledong County and provide a scientific basis for rational fertilization, Ledong County Agricultural Technology Center combined with soil testing and fertilizer project, a total of 2 481 agricultural samples were collected in the county from 2008 to 2009, Soil organic matter, pH, available nitrogen, available phosphorus and available potassium were determined for all the samples. Soil samples were extracted from available samples for calcium, magnesium and sulfur for a total of 14 637 times. Through soil field survey and laboratory analysis, the content and distribution of soil nutrients in farmland in Ledong County were basically ascertained, which provided the scientific basis for farmers to farm in a scientific way.
