Study on Distribution Characteristics of Mineral Nutrients in Fritillaria hubeiensis

Abstract

The contents and correlation of various mineral elements in soil and roots, stems and leaves of Fritillaria hubeiensis were analyzed and evaluated to supply basis for diagnosis of soil mineral nutrition and rational fertilization of Fritillaria hubeiensis. The contents of Phosphorus, potassium, calcium, magnesium, iron, zinc, manganese and copper were tested by the inductively coupled plasma, and the results were analyzed by SPSS11.5 software. The total contents of manganese, phosphorus, potassium, calcium and magnesium in soil and roots, leaves and stems of Fritillaria hubeiensis were different with different cultivation bases. The order of Fe and Cu contents was root > leaf > stem. The distribution of Zn showed a trend of “root > stem > leaf.” Between potassium content of soil and root, it was a significant positive correlation. But there was a significant negative correlation between Zinc content of soil and root. The total contents of calcium and iron were positively correlated between roots and stems. The total contents of Phosphorus, potassium, magnesium and copper were positively correlated among stems and leaves, while the contents of Mn were positively correlated. Therefore, Fritillaria hubeiensis mainly regulates the amount of mineral nutrients through selective absorption.
