To evaluate microelement status in citrus leaves in Chongqing, 871 leaf samples were collected from 871 citrus orchards in 14 main citrus production counties (districts), and 5 essential microelements were quantitatively analyzed. The results showed that the content ranges of Fe, Mn, Zn, Cu and B in citrus leaves were 18.00-362.10 mg/kg, 5.54-219.09 mg/kg, 1.00-83.95 mg/kg, 0.55-40.28 mg/kg and 7.19-435.49 mg/kg, respectively. The proportions of leaf Fe, Mn, Zn, Cu and B in insufficient level (deficient level or low level) accounted for 8.73%, 30.43%, 91.50%, 45.35% and 27.67% ,respectively, and in optimum level accounted for 53.73%, 68.31%, 8.50%, 44.89% and 65.56% respectively, however in excess level (high or excessive) were 37.54%, 1.26%, 0.00%, 9.76%, and 6.77%, respectively. Among the five microelements, the percentage of leaf Mn and B in optimum levels was the highest, and that of leaf Zn was the lowest. The proportion of leaf Fe content exceeding optimum level was the largest, reaching 37.54%. In most of the citrus orchards, rich and deficient of some microelement coexist, indicating poor balance of leaf microelement status. The proportion of orchards with 5 or 4 microelements in optimum levels was only 0.69% and 12.06%, respectively. Therefore, in citrus production, attention should be paid to the supplement and balance of microelements.
