摘要
Nanfeng orange is a world famous fruits, but its quality changes remarkably with the producing area. The present paper studied the contents of heavy metal mineral elements and microelements in soil planting Nanfeng orange by ICP-MS/ICP-AES and in order to find the dominant factors that affect the quality of Nanfeng orange in soil. The results showed that the contents of B, P, K, Mg and Ca, especially B, P and K were much higher in soil where the quality of Nanfeng orange is palatable than those where Nanfeng orange is unpalatable,. but the contents of Fe, Mn, Si, Cu and Zn were lower in soil where the quality of Nanfeng orange is palatable than those where Nanfeng orange is unpalatable. These data indicate that B, P, K, Mg and Ca, especially B, P and K, affect the quality of Nanfeng orange significantly.
