The present application belongs to the field of fertilizer preparation, and particularly relates to an active silicon-calcium-potassium-magnesium fertilizer, and preparation and application thereof. The active silicon-calcium-potassium-magnesium fertilizer contains biomass ash 60%, mineral humic acid 30% and binder 10% by weight. The active silicon-calcium-potassium-magnesium fertilizer is used as base fertilizer or topdressing. When used as base fertilizer, the application amount is 200 kg, and when used as topdressing, the application amount is 50 kg. The present application uses biomass ash of a biomass thermal power plant as the main raw material, adds appropriate amount of mineral humic acid, uses clay as binder, and uses granulation process to prepare granules, and then uses film spraying technology to inoculate functional bacterial agent. On the one hand, the present application solves the resource recycling of a large amount of biomass ash of a biomass power plant, and on the other hand, the present application improves the activity of silicon, calcium, potassium and magnesium in the product, and meets the needs of crops for silicon, calcium, potassium and magnesium.
