本文采用了熵权系数法对平昌县白衣镇的土壤肥力进行了综合评价并针对于当地的土壤肥力情况提出一些施肥建议。结果表明该地区土壤综合肥力均在3级或3级以上水平其中3级质量土壤分布最广占样点数的94.53%2级质量土壤占全部土壤的5.47%无1级和4级土壤质量样点分布。土壤肥力综评值与有机质、全氮、碱解氮、有效磷及速效钾均有极显著正相关性。
In this paper, the entropy coefficient method was used to evaluate the soil fertility in Baiyi Town, Pingchang County. Some fertilization recommendations were made according to the local soil fertility. The results showed that the comprehensive fertility of soils in the region was all above Grade 3 or above, among which the grade 3 quality soil was the most widely distributed, accounting for 94.53% of the sample size. The Grade 2 quality soil accounted for 5.47% of the total soil without Grade 1 and Grade 4 soil quality samples distributed. Comprehensive assessment of soil fertility and organic matter, total nitrogen, available nitrogen, available phosphorus and available potassium were significantly and positively correlated.
