采用主成分分析的方法对牡丹农艺指标进行了简化,然后采用典型相关分析法对反映案头牡丹生长状况的一组指标与反映基质理化性质状况的另一组指标进行分析。结果表明案头牡丹的农艺指标与基质理化指标相关极显著,两组指标之间的相关主要是由株花蕾数与容重有显著相关引起的。统计分析提示案头牡丹与基质配方理化性质的差别主要是由于容重造成的。案头牡丹的开花朵数主要与电导率的高低有关。
Principal component analysis (PCA) was used to simplify the agronomic index of peony. Then, a set of indicators reflecting the growth status of peony and another set of indicators reflecting the physical and chemical properties of peony were analyzed by canonical correlation analysis. The results showed that the agronomic index of peony was significantly correlated with the physico-chemical indices of the maize. The correlation between the two indices was mainly caused by the significant correlation between the number of flower buds and the bulk density. Statistical analysis suggests that the difference between the physical and chemical properties of peony and matrix formulations is mainly due to the bulk density. The number of flowers on the desk peony mainly related to the level of conductivity.
