摘  要:
应用灰色关联分析方法对林下参生长与土壤养分因子间的关系进行关联度分析。结果表明:主要土壤养分因子与林下参株高相关程度的大小顺序为有效磷>有效钾>pH值>有机质>含水量>全氮;与茎粗相关程度的大小顺序为有效磷>有效钾>pH值>有机质>含水量>全氮;与叶长相关程度的大小顺序为有效钾>pH值>有效磷>含水量>有机质>全氮;与叶宽相关程度的大小顺序为有效磷>有效钾>含水量>pH值>全氮>有机质。其中,对林下参生长影响的主导土壤养分因子为有效养分、pH值、土壤含水量和有机质。

摘  要:
The relationship between soil nutrient factors and growth of panax ginseng under forest was studied by grey association analysis.The results show that correlativity of soil nutrient factors and strain height of Panax ginseng under forest: available P>available K>pH value>organic matter>water content>total N;correlativity of edaphic factor and stem diameter: available P>available K>pH value>organic matter>water content> total N;correlativity of soil nutrient factors and leaf length: available K>pH value>available P>water content>organic matter>total N;correlativity of soil nutrient factors and leaf width: available P>available K>water content>pH value> total N>organic matter.Major edaphic factors had influences on growth of Panax ginseng under forest and soil nutrient factors which were available nutrient,pH value,soil water content and organic matter.
