An application of desulphurized waste of coal fired flue gas and an application method thereof for saline alkali land forestation belong to the technical field of saline alkali land improvement. For the application method, soil samples are firstly taken and analyzed to obtain pH values, total salt contents and alkalization degrees of different sections, different amounts of the desulphurized waste of coal fired flue gas are applied according to the alkalization degrees of the saline alkali land, and saline-alkali resistant trees such as Populus bolleana lauche, Populus popularis, weeping willow, Chinese scholar tree, and the like, can be chosen for planting. In the planting process, the land is firstly uniformly leveled, the dimension of a surrounding tree well is determined by the size of the tree, soil is taken out, then the desulphurized waste of flue gas and an organic fertilizer with different proportions and the original soil are uniformly mixed and backfilled to the well, a sapling is put into the tree
