【摘要】[目的]探索荔浦芋种植过程中土壤养分的含量变化及各养分含量的相互关系,为农业生产提供指导.[方法]在荔浦芋种植过程中的4个时期分别采集土样,并且检测分析.[结果]pH值与土壤有效养分含量密切相关,施加追肥后,土壤pH值明显升高;碱解氮含量在种植前后差异明显;有效磷、有效钾含量随着肥料的施加逐渐增加;微量元素有效态含量在种植过程中也发生了相应的变化.[结论]土壤养分因素之间存在密切联系,各养分含量在种植过程中也发生了相应的变化.适时对土壤养分指标进行检测、分析,才能掌握其变化规律.%[Objective] The research aimed to explore the content change rules of soil nutrient and the relationship among the elements for Lipu taro production. [ Method ] Soil samples were collected and detected in four stages of Lipu taro cultivation process. [ Result ] pH value closely related to soil effective nutrients and increased significantly after fertilization. Alkali hydrolysable N value was significantly higher before planting. Available P value and available K value gradually increased in the planting process. The available state content of microelements changed correspondingly at different periods. [ Conclusion] There was close relation among soil nutrient factors and their contents changed in the process of Lipu taro cultivation. Soil nutrient targets should be detected and analyzed at the
