关联分析法在筛选参后地土壤敏感因子上的应用

Application of the Correlation Analysis Method in Filtering Sensitive Factors of Ginseng Soil

通过灰色系统中的关联分析方法,在参后地非生物因子中,将有机质、全氮、有效磷、碳氮比这四种因子进行比较,筛选出有机质、全氮、碳氮比这三种因子作为影响人参根重的敏感因子。

Through the correlation analysis of grey system method, this paper compares organic matter, total nitrogen, phosphorus and carbon-nitrogen ratio among abiotic factors of ginseng soil, and filters out the sensitive factors of organic matter, total nitrogen and car- bon-nitrogen ratio that affect the weight of the root of ginseng.
