野生翘鳞肉齿菌菌塘土壤理化性质研究

采用相关性分析和主成分分析方法对野生翘鳞肉齿菌菌塘土壤样品的12个养分指标进行分析,结果表明,野生翘鳞肉齿菌喜爱弱酸性的环境,土壤养分指标除交换性钙离子稍有偏斜其余都符合正态分布。12个养分指标可以简化为5个主成分,它们所提供的信息量占总信息量的84.30%。其中有机质、全氮、有效P、有效K,有效Mn、有效Zn在成分指标中起决定作用。...

Summary:采用相关性分析和主成分分析方法对野生翘鳞肉齿菌菌塘土壤样品的12个养分指标进行分析,结果表明,野生翘鳞肉齿菌喜爱弱酸性的环境,土壤养分指标除交换性钙离子稍有偏斜其余都符合正态分布。12个养分指标可以简化为5个主成分,它们所提供的信息量占总信息量的84.30%。其中有机质、全氮、有效P、有效K,有效Mn、有效Zn在成分指标中起决定作用。
Bibliography:Twelve nutrient indexes of fungal colony soil of Sarcodon imbricatus were tested in this study by correlation analysis and the principal component analysis method（ PCA）. Statistical analysis showed that wild Sarcodon imbricatus favored slightly acidic environment,and the soil nutrient indexes conformed to normal distribution except that the exchange of soil nutrients calcium were slightly skewed. 12 indexes were simplied into 5 principal components using principal component analysis,all of which provided 84. 30 % cumulative variance in which organic matter,total nitrogen,available P,effective K,effective Mn,Zn played decisive roles in the effective component indicators.
