The invention relates to the technical field of soil improvement, and particularly discloses a method for synchronously retarding soil acidification and hardening and improving soil fertility, which comprises the following steps: (1) soil acidification degree determination: determining the pH value of a soil sample; (2) applying a base fertilizer: spreading the base fertilizer into the ditches, uniformly mixing the base fertilizer with surface soil, covering the soil, and immediately irrigating after the base fertilizer is applied; (3) applying a soil conditioner: applying the soil conditioner to each apple tree; (4) topdressing: performing topdressing for three times before germination, before bagging and in a fruit swelling period; (5) keeping agronomic measures such as pruning, branch pulling, flower and fruit thinning, weeding, bagging, pest control and the like consistent with local habits; the soil conditioner disclosed by the invention contains three components including the silicon-calcium-potassium-m
