摘要
植烟土壤养分丰缺状况的综合评价在平衡施肥技术研究中具有重要的意义。本文简要介绍了土壤养分数据分析的统计方法,主要包括土壤养分的描述性统计分析、次数分布图(表)分析和基于土样相似性距离的聚类分析,并对土壤养分丰缺状况评价、烟草专用肥配方筛选等有关问题进行了讨论。
Multifactorial evaluation of the status of soil fertility in tobacco-growing areas plays an important role in balanced fertilization. Some statistical methods for analyzing soil nutrient content were introduced briefly, including descriptive statistics, figure (table) of frequency distribution, and cluster analysis based on similar distance among soil samples. In addition, some issues on evaluating the status of soil nutrient and recommending rational fertilizer application were discussed.
