Under the field condition, the distribution and abundance of the nutrient (N, P, K, Ca, Mg, Zn, Mn,Cu, Fe) in the citrus and the agro-chemistry of the nutrient elements were analyzed in the present study. The results showed that Ca and K had the maximal contents in the trunk and flower respectively. The distribution of macroelement in the root and leaf was similar. The macroelement in the plant parts which was uptaked strongly was consistent with that in the surface soils. The microelement of Zn, Mn and Cu was uptaked moderately, while the uptake of Fe was very weak. The nutrients were controlled strictly by the background contents of the soil. The amounts of elements in the leaf, flower and root were significantly higher than in the other parts of navel organs, while the trunk and fruit was relatively lower. In the test area, the contents of N and P were deficient but K was rich, so the ratio of N and P should be adjusted in order to improve the supply of N and P by the soil.
