摘要
根据改进的内梅罗综合指数法,选择pH值、有机质、碱解氮、有效磷、有效钾、全氮、全磷、全钾,对永胜县涛源村新垦土地的土壤肥力进行综合评价。结果表明:评价区域的土壤综合肥力属于瘦瘠水平,其中土壤呈碱性,有机质含量中等,氮、磷缺乏,钾稍缺。
The soil fertility index of newly reclaimed field of Taoyuan Village in Yongsheng County was appraised with improvement Nemero Index by selected pH value,soil organic matter,available nitrogen,available phosphorus,available potassium,total nitrogen,total phosphorus and total potassium.The results showed that the soil composite fertility was poor,the soil was alkaline,the content of organic matter was medium,nitrogen and phosphorus were poor,potassium was slightly poor.
