| Abstract: | The results of experiment showed that the nutrient uptake by Citrus grandis and the nutrient balance in the trees were improved by suitable application rate of rare earth. In consequence, the rate of fruit setting and the yield of Citrus grandis were increased. Moreover, sugar in the tree body was also increased and the acidity was decreased. Therefore, the rare earth is significant for raising yield and improving quality of Citrus grandis when it is used at suitable time and at suitable application rate. |
