摘 要：
Nutrient elements of K, Ca, Mg, P, Cu, Zn, Mn, Fc, and B inorchard leaves were extracted with 1N hydrochloric acid (HC1) inpolyethylene bottles and analyzed by inductively coupled plasmaatomic emission spectroscopy. The experimental result suggested thatbesides Fe and P, other elements were extracted completely with I NHCl. This analytical procedure is simple, easily manageable andaccurate. Meanwhile, we compared this procedure and dry ashingmethod and got identical resuls. Standard reference material of orchardleaves, GB 7171-87, and peach leaves, 82301, were analyzed and thethe data were identical with certified values.
