求文对名贵中药材霍山石斛各部位中必需微量元素和必需氨基酸的含量进行了测定,对人体和植物共同的必需微量元素与人体必需氨基酸间的相关性进行了研究。结果发现,Cu、Zn、Fe与必需氨基酸呈负相关;Mg、Ca、Mn与必需氨基酸呈正相关。欲提高霍山石斛中必需氨基酸含量,建议少施Cu、Zn、Fe粪肥料,适当多施Mg、Ca、Mn类微肥。
In this paper, the contents of essential trace elements and essential amino acids in various parts of Dendrobium huoshanense, a precious Chinese herbal medicine, were determined. The correlation between the essential trace elements in human body and plant essential amino acids were studied. The results showed that there was a negative correlation between Cu, Zn, Fe and essential amino acids; Mg, Ca and Mn were positively correlated with essential amino acids. To increase the content of essential amino acids in Dendrobium huoshanense, it is advisable to apply less Cu, Zn, Fe manure and apply more Mg, Ca, Mn fertilizer.
