The invention provides a saline-alkali land desulfurized gypsum carbon-based soil conditioner as well as a preparation method and application thereof, and mainly relates to the technical field of soil improvement. The flue gas desulfurization gypsum carbon-based soil conditioner for the saline-alkali soil is prepared from the following raw material components: flue gas desulfurization gypsum, biochar, Hangjin 2 # soil, wood vinegar, ectothiorhodospirillum halophilum and flavobacterium acidificum. The prepared soil conditioner increases nutrients for soil and promotes crop growth while repairing the saline-alkali soil, the chemical fertilizer amount of a soil conditioner test group is reduced by 20% compared with that of a control group, the raw materials are all industrial and agricultural solid wastes, the preparation is easy, the cost is low, the national environmental protection requirement is met, and the method is suitable for large-scale popularization and application. The fertilizer is reduced and incr
