The invention relates to a saline soil restoration material for weathered coal soil and a preparation method thereof. The restoration material consists of the following elements: weathered coal: 55 to 65 portions; monoammonium phosphate: 10 to 12 portions; carbamide: 2 to 6 portions; ferrous sulfate: 2 to 6 portions; zinc sulphate: 1 to 4 portions; manganous sulfate: 1 to 3 portions; calcareous adhesive: 5 to 15 portions and dilute nitric acid: 15 to 30 portions. The saline soil restoration material can be used as basic fertilizer or additional manuring. The saline soil restoration material for weathered coal soil can neutralize soil alkalinity, and the active calcium ion contained can replace the sodium ions absorbed on soil colloids which can be washed out of soil by rain water or irrigation water. The invention can raise the organic content in alkalization soil, make up for the insufficiency of the contents of the medium elements and trace elements in alkalization soil, and the active humic acid contained in the saline soil restoration material can promote plants to grow fast.
