摘要：

掌握织金县红托竹荪中矿质元素的含量水平,通过适当调控土壤,利于红托竹荪生长,也可为红托竹荪的营养性和安全性评价提供参考依据。通过对基地土壤-红托竹荪矿质元素钾(K)、钙(Ca)、铁(Fe)、锌(Zn)、硒(Se)的测定,并对其进行相关性分析。结果表明：土壤中矿质元素平均含量大小为Fe>K>Ca>Zn>Se,红托竹荪中矿质元素平均含量从高到低依次为K>Ca>Fe>Zn>Se;富集能力最强的为钾元素;基地土壤-红托竹荪间的矿质元素相关性统计显示矿质元素Fe与土壤pH呈显著负相关(P<0.05);土壤(Ca)-红托竹荪(Ca、Zn)、土壤(Se)-红托竹荪(Se)为极显著正相关(P<0.01);土壤(K)-红托竹荪(Fe、Zn)、土壤(Fe)-红托竹荪(Fe)为显著正相关(P<0.05)。基地土壤间矿质元素的相关关系为：K-Fe、K-Se、Ca-Zn呈极显著正相关;K-Ca、Ca-Se在0.05水平上呈显著正相关;Ca-Fe、K-Fe呈极显著负相关。红托竹荪中矿质元素K-Zn、Ca-Fe呈显著正相关;K-Ca、K-Fe、Ca-Zn呈极显著正相关。其他矿质元素则无显著相关关系。在土壤中添加一定浓度的钾、钙元素可能促进红托竹荪对其他矿质元素的吸收,一定程度上可能提高竹荪的品质。

Abstract:

The study aims to understand the contents of mineral elements in Dictyophora rubra in Zhijin County of Guizhou Province to facilitate D. rubra growth by properly regulating the soil, and to provide a basis for the nutritional and safety evaluation of Dictyophora rubra. Through the determination of mineral elements of potassium (K), calcium (Ca), iron (Fe), zinc (Zn) and selenium (Se) in the soil of D. rubra production base, the correlation analysis was carried out. The results showed that the average content of mineral elements in soil was in the order of Fe > K > Ca > Zn > Se. The average content of mineral elements in Dictyophora rubra was in the order of K > Ca > Fe > Zn > Se, potassium is the most abundant element. The correlation statistics of mineral elements between the base soil and D. rubra showed that the mineral element Fe had a significantly negative correlation with soil pH (P<0.05); there was a very significantly positive correlation between soil Ca and D. rubra Ca and Zn, and soil Se and D. rubra Se (P<0.01); there was a significantly positive correlation between soil K and D. rubra Fe and Zn, and soil Fe and D.rubra Fe (P<0.05). The correlation of mineral elements in the soil showed very significantly positive correlations between K and Fe, K and Se, and Ca and Zn; there was a significantly positive correlation between K and Ca, and Ca and Se at the level of 0.05; there was a very significantly negative correlation between Ca and Fe, and K and Fe. The mineral elements K and Zn, and Ca and Fe in D. rubra had a significantly positive correlation; K and Ca, K and Fe, and Ca and Zn had very significantly positive correlation. Other mineral elements had no significant correlation. Adding a certain concentration of potassium and calcium in the soil could promote the absorption of other mineral elements and improve the quality of D. rubra to a certain extent.

Key words: Dictyophora rubra in Guizhou, mineral elements, correlation analysis, enrichment coefficient, soil in the base
