Abstract : Experiment was conducted in a 200ha mango farm with the t10-year-old trees of Kate mango cultivar. The trees suffered seriously with chlorosis were selected for material for correction by using 0.3% ferrous sulfate. 4 treatments were used: root injection, trunk injection, spraying and cut root soaking. Results showed all treatments could greatly improve the chlorosis. But the best effectiveness was received from root injection, before injection, the leaf chlorophyll content was 0.200 mg/g, but after injection increased to 0.329, increased by 64.5%. Then the trunk injection, before treatment the chlorophyll content was 0.245 mg/g, after injection increased to 0.381 mg/g, increased by 55.51%. Using root injection of 0.2% amino acid Fe also could greatly improve the chlorosis, the increment could reach 68.00%.
